Four tremors hit the city on Monday while the latest series began at about 0440 BST on Tuesday.

The first earthquake, measuring 3.2 on the Richter scale, shook the area at 0845 BST on Monday.

Four hours later it was followed by an earthquake 11 times more powerful which shook buildings across the city.

There were then powerful aftershocks.

The British Geological Survey said the lunchtime earthquake measured 3.9 on the Richter scale.

The earthquakes took place less than a month after a much stronger event rocked Dudley in the West Midlands.

I have just felt another small quake - I'm going to miss them when they are gone!
Bruce Mitchell, Student, Manchester

9.25am Thursday 24th October 2002. Large Tremor felt in Old Trafford area of Manchester and confirmed by friends in buildings of adjacent areas. Felt as strong as first quake on Monday morning 8.45am. Computer screens rattled for 5 seconds following an audible rumble.
gary brown, england

I felt the latest quake at 9.15 this morning. It was like something out of a disaster movie. Walls shaking, filing cabinets rattling around and people diving under their desks for safety.
Bernard Edwards, UK

Many people in Manchester are convinced that we might be leading up to something a little larger

Ross Alderton, UK

I am a Geography student studying at The Manchester Metropolitan University in the city centre. I have felt and experienced over 5 different Earthquakes in the last few days. I've never experienced such an amazing feeling and every time it has shocked all of the people I live with into silence. Many people in Manchester are convinced that we might be leading up to something a little larger than just a tremor, and I as an academic working in Manchester must warn the BGS not to underestimate the power that can be released from 'fault slips.' In the past such faults, as the one under Manchester is currently showing, have stored many hundreds of years of tension up. I do believe that this tension is being released now in the form of an earthquake swarm. Earthquake activity like this is not fully understood.
Ross Alderton, UK

I don't mean to sound alarmist, but how are geologists absolutely sure that these "esrthquake swarms" happening in Manchester are simply a slow release of seismic energy? What if these tremors are the reactivation of an old fault that may cause a catastrophic quake in Greater Manchester at some point in the future? I recall hearing that people should not become complacent because there have been no major earthquakes in a particular location in recorded history. Major quakes can happen on timescales of thousands of years.
Patrick Shiels, Dublin, Ireland

Being a geographer I am very interested in the latest phenomenon to hit Manchester. I have felt many of them and am really excited about this little swarm we are having. As long as they don't become too big, keep them coming I say.
Tom Wadsworth, Manchester

I absolutely love these earthquakes!

Sarah Ruston, England

I absolutely love these earthquakes! When the first one came on Monday, I thought a car had crashed through the front of our house. I study at Salford University, and I am now always trying to get to my lessons early now, as they are all on the top floor of the building, which means I get to feel them more, and I don't want to miss them!
Sarah Ruston, England

Having experienced nearly all the recent quakes including the Dudley one, I'd say Monday afternoon was the most severe, regardless of Richter scale results. Dudley's felt like a large vehicle driving down the road, Monday afternoon's felt like an aeroplane hitting heavy turbulence. I've just been woken by another (4am 23/10/02)
Martin George, England

I felt the tremor just after 4.30am on the 23rd Oct on the 6th floor of a Salford Quays hotel, which woke me up suddenly. The bed seemed to shake from end to end for no more than a couple of seconds and there was a tinkling sound from the objects in the room. I also saw rather than felt the effects of the one at lunchtime today at Salford University when the image from a projector and the screens started shaking. All very exciting.
Sylvia, UK

Lovely - 2:58am and rocked out of bed by another tremor!
Mike Holbrough, Manchester, UK

I don't think it's anything to worry about. It's probably just Beckham and Keane dropping their wallets.
Michael Pearce, UK

I work in the City Centre of Manchester and after the series of tremors we have experienced we are quickly becoming used to waiting for the next one. When outside you can barely sense them but on the sixth floor of an office building it is all too clear that something has occurred. I think people are holding sweepstakes on how many we can get in one day.
Michael Fiddaman, England

A number of properties have suffered damage in the area in which we live

The Scotts, England

We live within a mile of the epicentres of these earthquakes/tremors, its is quite frightening when then are occurring over and over again, especially for the children aged 5 yrs and 7 yrs. We have been at home during all the tremors due to the fact that it is half term at school. A number of properties have suffered damage in the area in which we live, a neighbours chimney stack collapsed and had to be taken down last night. Our roof tiles have also shifted and the chimney stack seems to be twisted.
Craig, Maria, Bethany & Nicole Scott, England

I was in Manchester Student's Union bar when the earthquake struck. The television screens went off and suddenly the roof was shaking and rattling. Everyone stopped and looked at each other, wondering what was happening. Only a few seconds later, it all happened again. It was very strange and a little unnerving, but thankfully not a drop of my Guinness was spilled.
Lisa, England

It was exciting at first, but after 15 I'm getting a little worried

Claire Smith, England

I've felt 7 of the last 15 quakes, by far the most frightening was lunchtime on Monday. It was exciting at first, but after 15 I'm getting a little worried and beginning to wonder if we are about to experience a spectacular one.
Claire Smith, England, Manchester

I was drinking a cup of tea at about 1.30 today when suddenly I felt this tremble and I spilt tea down my shirt. I looked round and saw some startled faces, and I grabbed the nearest railing. My heart was beating fast and I quickly broke into a sweat and knew that the inevitable had happened - oh my gosh I thought to myself it's an earthquake. It took me a while to calm down, but I soon regained my senses and took time to comfort others who had also been startled by the tremors. There were lots of pale faces. Let's hope the experts are right - that the first ones are the biggest ones.
Matthew Alderton, UK, Manchester

Scientists, please explain: I was stood outside my office having a sneaky smoke at 13:35 on 22/10 and felt absolutely nothing. I came back in the office and everyone else enjoyed the quake sitting at their desks when I really wanted to feel the tremor underfoot!! They were sat at their desks and felt it just like yesterday, I'm outside, on the car park. Nothing!!! Gutted.
Martin Haywood, Manchester, UK

I was in university in the library when the lunchtime earthquake struck. Part of the ceiling started to fall down and we had to be evacuated! Still receiving the odd tremor now at 13.46 Tuesday.
Sarah, UK

Just felt another one about five minutes ago. It's the first one I felt and was one the strangest feelings I've ever had...
Dan Fell, Manchester, UK

There has been another earthquake

Tom Sanders, UK

There has been another earthquake at 1.30pm Tuesday 22nd October. I work on Oxford Road on the 4th floor of the Williamson Building, which sustained another large jolt today.
Tom Sanders, UK, Manchester

Where is the epicentre for all the recent Manchester earthquakes ?
Nicola Barnett, UK

Another tremor in Manchester 13:30 approx. Around as strong as the first yesterday morning. Still feeling the after shocks now (13:38)
Amanda Denny, UK

Just felt another earthquake, I felt such serenity, like being in the centre of the storm yet controlled by it, so peaceful, so calm, so beautiful, I will never forget the awesome wonder of this experience.
Rich Martin, Britain

I just felt today's tremor at 13.30hrs whilst sat at my desk in the City Centre. The desks at the top end of the office all slid to the other end - I looked outside and saw a huge fissure just off Portland Street and people starting to fall inside it. It was just then a T-Rex came out of the hole and caused me to spill my coffee over my keyboard.
Garry Wild, England

If the country stops for snow, what chance will we have with a serious earthquake, my question is what plan does the government have in place to cope with a major earthquake in the UK?
Jonathan farber, UK, Knutsford, Cheshire

Hope that was the last one!

Stephen Baker, Manchester

Another earthquake at 13:30 on Tuesday 22nd and the building I'm in, St James building, on Oxford Street rumbled and made a low thudding noise. It's strange to hear a building making such a noise, you are listening around to the almost sub-sonic gurgle of the building and getting scared - wondering just what it is that the earthquake is doing to make such a dense thudding noise to the building. Hope that was the last one!
Stephen Baker, Manchester, UK

There has just been another tremor, I'd guess it was somewhere in between the strength of Monday Morning and Monday afternoon's tremors. It does make you wonder if these tremors are building up to something bigger? Is there any advice for what to do in case of a seriously strong Earthquake?? (Without causing panic of course)
Nick Watts, Audenshaw, Manchester, UK

We have just had another one 13:27
James, Salford, UK

Its Tuesday, 13:35, and we have just had another tremor!

Gabrielle, UK

Its Tuesday, 13:35, I'm at work in the Arndale Centre Manchester and we have just had another tremor!
Gabrielle, UK

It just happened again! I'm getting used to them now but it's still a scary experience when everything shakes!
Heather at Royal Exchange, Manchester city centre, England

We have just felt another small quake/tremor here at Salford. I'm not the type of person to panic easily but the fact that we have felt these over the past two days is even starting to make me feel nervous.
Tracey Shaw, UK

Another two shakes at 13:26 today. Not severe but this is getting silly.
Mike, Stockport

I was visiting our Manchester Office having a mock interview with my manager. I thought it was a bomb, but there was no blast. It was unnerving especially as the aftershock struck and we wondered if we should evacuate the building; it crossed my mind there might be other bigger ones.
James Terence Statham, England

I was working at the Manchester Royal Eye Hospital and experienced both quakes. It was particularly unnerving to patients awaiting surgery and could have adversely affected the patient in the operating room as it caused equipment to shake and move about. The lunch time quake was especially strong and quite scary when you are standing in a building that is very old! Neither felt like minor quakes to the staff working there where concern for our patients safety was paramount.
Tracy Birchall, UK

I've felt much worse in NZ, but this series of quakes does raise some safety concerns. I

Eleanor Ryan, Manchester

I'm living in Central Manchester, but am from Wellington, New Zealand, which sits on a major, active fault line and where earthquakes are common. I assumed I'd left them behind when I left NZ! I've felt most of the tremors today. I've felt much worse in NZ, but this series of quakes does raise some safety concerns. In NZ we are taught in school how to respond to an earthquake, to minimise danger of injury. This included standing under doorframes, heading for the nearest table for cover and staying away from windows if possible. We were always advised to stay inside until the all clear was given, a tactic learnt after people were crushed by falling debris during the Hawkes Bay earthquake of 1931. Take a look at www.gns.cri.nz, the website of the Institute of Geological and Nuclear Sciences which gives some very clear guidelines on earthquake safety. Just a thought!
Eleanor Ryan, Manchester, England

I cannot sleep after the last 2 earthquakes woke me up. They seem to be getting more and more powerful, the ones this morning caused a picture to fall from my wall. I was lay in bed next thing there was a very loud rumble, vibration then movement. There is talk now that we are heading for something bigger, although I don't believe it. Why Manchester, why now and why so many?
Adam Murphy, Manchester England

Sat here all bleary-eyed at 6.40am. Just knew there had been another one at around 4.40am, my bed was shaking and I could hear items on my dressing table moving. Didn't know if I was dreaming or not - thank heavens for the BBC website! At least I know I'm not going mad now.
Madeline Edgar, Manchester, England,

There were cries of 'again, again'.

James Beamish, England

The one in the morning felt like someone had fallen out of bed on the floor above, but the one at lunchtime was much more impressive. We were having a lecture at the University, when the whole room shook for a few seconds. Bewildered looks spread across the room, and the lecturer had a chance to say a couple of words before the second part of it came. No one panicked; we were at about ground level, so it didn't seem that bad. In fact, there were cries of 'again, again'.
James Beamish, England

I'm a Mexican post-graduate student at the University of Manchester and I was at a lecture when the floor started moving. Suddenly, everybody started to evacuate the building. I'm used to earthquakes but it was a little strange to have one here in the UK.
Luis Javier Cu�, UK

I was in the kitchen cooking my breakfast, I was boiling an egg in a pan. When the earthquake struck my pan came crashing off the stove. All the hot water burnt my leg, I was in shock. Never have I experienced anything like it, I didn't know if it was terrorists, or an earthquake. I was so frightened. I had trouble getting through to the hospital because there were so many emergency calls.
Rob McBride, England

People here need educating as to what to do in a quake

Marnie Stevens, UK

I'm a student in Manchester, and found the series of earthquakes to be not only frightening, but disruptive too. As it is something British people are unused to - no-one knew what to do. Some university staff thought we should ring the fire bell to evacuate! After the tremor has finished - that's it, nothing more to see. People here need educating as to what to do in a quake - but mainly not to panic.
Marnie Stevens, UK

I was brought up in a corner shop in Bolton. My Auntie Ellen came from a family of Miners in Cumbria. She reported many minor earth tremors in the Manchester area in the 50's. She used the 'budgie' scale. If the budgie or canary fell off its perch in the night there had been an earth tremor. This heuristic was also used by many customers with mining connections who came into the shop. Or were these adults getting legitimate amusement by teasing a curious, earnest and probably pompous child?
Martin, UK

My poor African gray parrot Timmy was shaken from his perch this morning. I came downstairs after the quake woke me up to hear the poor bird flapping about in the bottom of his cage. He had a strange look on his face
Keith Watkins, Stockport

I panicked and ran out screaming

Oliver Sudden, England

I must admit I panicked and ran out of the office screaming and waving my arms in the air while all my colleagues just sat and looked at me. I'm feeling a bit foolish now - people keep pointing at me and laughing. I'm quite looking forward to going home time now.
Oliver Sudden, England

I thought it was a bomb attack so took cover under my desk. Not many of my colleagues noticed me gone though.
Adam Martin, Manchester, UK

The shock at 12:45 seemed much stronger and was quite frightening. There appeared to be a very load bang and then the whole building shook and shuddered. I heard things falling of the bathroom cabinets in the next room and my dog started running around in total confusion.
James, Salford, Manchester

I thought the ceiling was going to collapse

Simon Yates, Manchester

I was sat at my desk at work in Middleton when at 12.45 the whole building shuddered, a lot stronger than the tremor in the morning. I thought the ceiling was going to collapse!
Simon Yates, Manchester, England

What a strange feeling. There I was eating my lunch when the first quake hit. We were just talking about how much bigger this quake was than the one this morning when bang, another quake hit. Shortly after the second quake, we were evacuated from our building as a precaution. A day to talk about.
Richard Garland, UK

I felt the earthquake at approx 12.45. It was much bigger than the quakes this morning. The quake was so big it made my headset fall off my head. The windows rattled so much they nearly smashed.
Mark Ledingham, England

I felt this morning's quake, but at just after 12:45 this afternoon my office building just started rocking - it felt at least twice as strong. Most employees here (near Man City) scrambled outdoors and are still jittery about returning.
Michael Pearl, England

The whole building rocked back and forth

A, UK

I didn't feel the morning Manchester earthquake but certainly felt the one this afternoon at approx 12:45 in Wilmslow town centre. The whole building gently rocked back and forth for about eight or nine seconds.
A, UK

I was working on the 14th floor of the Arndale tower. The tremors shook the whole tower and you could feel the floor moving beneath us. It was quite surreal but also quite scary when you think what could have happened!
Laura Whitworth, England

I was travelling in by car this morning when the first quake occurred and noticed only a small tremor. The second quake was much more disturbing. The PCs in our office started shaking quite badly and crashing noises were heard from a few items that been dislodged on the floors above us. A straw poll of colleagues in the office was that the second tremor felt far worst than the first. Bearing in mind how uneasy I felt at the small tremors here in Manchester makes you appreciate how alarming it must be for those living in countries where quakes are more frequent and severe occurrences.
Michele, Manchester, England

It appears that the quake set off the fire alarms at the MMU complex and two of the main buildings had to be evacuated for about 40 minutes.
Brian Hall, England

The second shakes were larger for sure, the whole house felt like a truck hit it, the aftershock was smaller but lasted longer
Alex Doig, England

I felt it... It woke me up!

John Wedge, Manchester

I felt it... It woke me up! I was lying in bed and thought that my house had been hit by a vehicle, or something, though I was aware that I didn't hear a crash and could not hear any engines running. Articles on my bedside cabinet were shaking, and I was surprised to find that the motion was going in all directions, and not just from side to side, as I'd previously thought.
John Wedge, Manchester, North England

I had just finished lunch on floor 19 of the Arndale tower. You could really feel the tremor magnified up there. My first thoughts were to get to ground level, but I must admit it didn't feel as strong as the 8:45 tremor this morning, which I felt in my apartment in Chorlton. I
Claire Evans, England

I was sitting in my office in Eccles. The office is on the third floor and it really did shake like something. Since I am from India, I have experienced some tremors which were as heavy as 6.0. But this one was also not a light one. For a second I thought a big 32 tonner had rammed through the office building!
Amit Ramchandani, India

I live in Billinge, it is about 19 miles from Manchester City Centre. The walls inside my house shook about 1245 hrs. I had heard about the earlier quake but it was fairly unnerving experience.
Shaun R. Rothwell, UK

I automatically held onto the table in case it got worse.

Ann Sainter, UK

I was on a computer on the second floor of the university physics department during the second quake. It felt like the whole building was rocking backwards and forwards and I automatically held onto the table in case it got worse. People rushed in from the labs saying they'd felt it too - no more experiments today then!
Ann Sainter, UK

My colleagues and I are at work at Manchester airport. The terminal shock twice about 10 minutes ago. We're wondering if its another aftershock.
CW, UK

I was at home watching TV at 12:45 when another earthquake hit. I was asleep for the one at 9am, but was shocked when I found out. The floor buckled and the windows shook. It lasted quite long as well.
May Ying Li, Manchester

I was in Stockport this morning and the quake shook the plates in the kitchen, then I came to Salford to work and being on the third floor the building shook, everybody was standing in the corridor looking nervous until it passed. The second was much stronger in the centre than in Greater Manchester for the first.
Emma Nixon, Manchester

It seemed to move in waves across the building

Rebecca Bennett Manchester

I felt 2 tremors at around 12.45pm today. The first was really strong, it seemed to move in waves across the building. A colleague checked out the windows believing that a truck or some large vehicle had drove into the side of the building. The window cleaners were in the office and they soon got down their ladders. It was all stomach churning stuff.
Rebecca Bennett, UK - Greater Manchester

Was in the basement getting my lunch, when I felt the one this afternoon. Was a bit scared, once I realised what had happened, by the time I got back to the office everyone had decided to evacuate the floor I work on, I think that was a bit dramatic.
Oscar, UK

The sharp nudge at 8:45 was the only thing to get this tired student out of bed. The aftershock caused me to choke on my toothbrush. The shudders themselves felt like living in a snow globe being attacked by violent mice.
Aubrey Hesselgren, England.

Earth tremors seem to affect the ability of some people to express themselves. Some of the comments here have reduced me to tears of helpless laughter. I paticularly like the one about violent mice attacking a snow globe. Let's have a Minister of Earthquakes who will arrange more earth tremors to cheer us up.
Chris B, England

My colleague and I were in the office on the third floor of the neuroscience building at Hope Hospital and just after 0845 this morning we felt a shuddering movement of the building for about two or three seconds. We both looked at each other and were amazed to realise that we had both felt it. Initially I thought I was imagining things.
Jill Holmes, UK

We didn't realise it was an earthquake until it was on the news

Lucy Dring, UK

I was in work on the 6th floor of a building at Salford Quays at 8.45. All of a sudden it felt like the floor was dropping from beneath my feet. For a split second I thought the building may collapse. Everyone went quiet and then started asking each other what was going on. We didn't realise it was an earthquake until it was on the news. It made me feel unsafe as I have never experienced anything like that before.
Lucy Dring, UK

I live in Knutsford, and there was a sharp bang at around 12:45 today, not like the one a few weeks ago in Wolverhampton which I also felt, and was more of a rumble. With this one, I thought the chimney had collapsed, or soot had collapsed down the chimney. No visible signs of damage anywhere.
Steve Bolton, England

I felt the second quake. I was just sat doing my homework on the computer in my mum and dad's room, when the computer screen started shaking. The wardrobe doors were also shaking quite loudly. I ran downstairs to my brother and sister who also felt it. I thought that at first it might have been a terrorist bombing or something of that sort. It was quite scary actually.
Jenny Carter, England

I didn't know what to do

Rob Hampson, England

It was really very frightening. I was in a sandwich shop in Manchester City Centre when the floor started to shake. I didn't know what to do, some people rushed to stand in the doorway to the shop, others stood frozen.
Rob Hampson, England

Yes, I was in Manchester this morning. I was doing a headstand, when the earth shook and before I knew it I was back on my feet.
David Barnes, England

I was watching the Harry Potter film with my granddaughter Hannah when the second shake came at 12.45. We were amazed when the settee we were sitting on started to move. We also heard a rumble. Hannah rang her father to tell him.
K Thomas, UK

I was at work in Altrincham. This morning when the quake struck. Most of the plaster of our walls fell off, and I head butted my screen. I hear there may be a volcano in Bolton.
Stuart Smith, UK, Altrincham

My legs were like jelly!

Tina Caution, UK

I had heard reports of the morning earthquake. At around 12.40 I was having soup. It wobbled like jelly, the floorboards under my feet trembled quite fiercely and the windows rattled. It was frightening enough to make me stand on my doorstep - as other neighbours did. Then there was a smaller quake. After that my legs were like jelly!
Tina Caution, UK

I was in a geology lecture at the University of Manchester when the earthquake struck. The lecture on global tectonics was actually just coming to a close. All of us in the lecture theatre froze as the shock waves moved through the building. The tutor nervously explained what was happening as the aftershocks followed seconds later. He decided that it was best to evacuate the building we were in because its so old. The earthquake didn't last for very long, but it was very strong.
Christine McClure, Manchester

I slept through the morning one, but was working on my PC when the 1245 tremor hit. It was weird, the room shook (not violently, but very noticeably) along with me and anything else in it. I thought something had blown up in the flat below me. I was a bit unnerved immediately after, then I thought "Cool, I just felt a wee earthquake".
Simon Buttress, England

This has highlighted how unprepared we are for quakes in this country.

Chris McClenan, England

We were on the second floor of Arkwright House near the sight of an IRA bomb. But we knew that this was different and that it must be an earth tremor. This mornings quake really shook the building but the second quake was much stronger. While everyone was very concerned no one knew what action should be taken and this has highlighted how unprepared we are for quakes in this country.
Chris McClenan, England

As a Los Angeles California native who is living and working in Manchester, I was very surprised to feel a sizeable tremor here in the UK. It made me feel a little homesick. The people I work with all took it very much in stride.
Jeff "Swampy" Marsh, UK

After experiencing the IRA bombing in Manchester whilst at work I could not believe another frightening incident here again in the city centre. I work on the 16th floor of a building right in Piccadilly centre of Manchester so I felt the tremors considerably. Your heart goes like the clappers and legs wobble. It feels the same as when you are in an aeroplane and you suddenly without warning hit turbulence...
Katherine Thorpe, England

Some people were close to tears

Peter Hackleton, England

I work for Deloitte & Touche in Manchester, on floor 10 of a floor 12 building. I can tell you it was pretty hair raising stuff. The floor shook, and file cabinets wobbled. Some people were close to tears. The immediate feeling was of total shock.
Pete Hackleton, England

Weeks after being woken up in Nottingham by the Dudley tremor, I was very surprised to feel another this morning shortly after I had got to work at UMIST in the centre of Manchester. Most of my colleagues looked around in disbelief saying, "Did you feel that?" Later on it happened again and the whole of our beautiful old building shook. We evacuated all the students to be on the safe side. Where will the tremors hit next?
Deborah Hogg, Manchester, UK

The second tremor knocked me to my knees. It was much stronger than the first two and I broke out into a cold sweat. I immediately phoned my mother to let her know I was OK after it had finished. Quite scary really.
Tommy Knockers, England

I don't think many people realised that anything was happening.

Christopher Harding, UK

My family and I were at the Manchester Aquatics Centre when the quake struck. The building moved, it was rather like a very heavy object had just "pushed" into the building. The effect only lasted a few seconds. I don't think many people realised that anything was happening.
Christopher Harding, UK

I was out walking my dog Minton when the first tremor hit and he ran off and sat under a tree! The second one was much worse when I was at work, I immediately phoned my partner Stu to see how Minton was after the second tremor.
Dan Bardsley, England

I was at happily in the physics department of Manchester University, when the building began to quite noticeably shake, everyone in the room fell silent and looked up and around trying to see if one of the big machines had fallen over or something. Then the building shook again, we thought something had crashed into the department and most people ran out of the building... just to be safe.
Jex, Uk

The dog went a little crazy

Lee Bennett, England

I had just sat down to my computer to begin my college work and my chair began to shake and the screen began to shake also. The dog went a little crazy and I thought one of the trucks outside had crashed but they had already left. At first I thought it was a blast of some sort and then I thought of the quake in Dudley but didn't think we would have two quakes so close to each other. One of my friends thinks the end of the world is on its way.
Lee Bennett, England

I was in work having my Lunch when the whole building shook. There are very fine hairline cracks appeared all over the building. We evacuated and had the building checked over before being able to return to work. Any excuse for an extra 1/2 hour for Lunch.
Christine Barber, UK

I arrived early at work hoping to get a head start, but instead was shaken up by our top floor office being shook by mother nature. My colleagues didn't believe me until the second earthquake shook. I feared for my safety, but realised that there was no threat of danger
Erica Lamb, Manchester

The fire alarms started going off and everybody started running out.

Philip Barnes, England

I was sitting in the library here at uni (I'm a law student) when all the shelves started to shake and there was a rumbling like a tank driving past outside. I was on the fifth floor of a tower building, so you could feel it shaking back and forth. The fire alarms started going off and everybody started running out. We all thought it was a bomb. It was pretty scary!
Philip Barnes, England

I was on the 4th floor, in a lecture at uni, when we felt the shaking. I knew it was a tremor straight away because I felt the same thing this morning. Class had ended and there were still a few people in the room. After the shaking we all ran out of the building. Don't know exactly how to feel at the moment except a bit scared.
Basil Baddoo, Central Manchester

Felt the earthquake this afternoon right through the office, the floor shook and we could hear the building juddering. Received email from a friend in Chorlton saying the floor shook and windows rattled there too. Although people I know in Cheshire didn't really notice it. The area around the stadium shook. Was a scary experience, but interesting!
Kim, England

The movement carried on for ten seconds or so after the actual shock finished

Michael Gill, GB

I was unaware of the first tremor as I was driving in to work; the second one was quite strong. I work in Droylsden in a three storey building. I'm on the top floor and I was aware of a load rumbling noise, then the building and floors shook and swayed considerably. The movement carried on for ten seconds or so after the actual shock finished. Very strange sensation.
Michael Gill, GB

I was walking in the centre of Manchester when the earth started to move. I initially thought that my lack of food had made me feel faint and only learnt otherwise when I returned to the office and everybody was talking about an earthquake.
Glenn Costin, Manchester, England

I was in Manchester�s Central Library when the second tremor hit around 12:45pm. Immediately I suspected a bomb, or an aeroplane crashing into the ground so I ended up taking cover under one of the desks. A minute or two later a second tremor hit the building. Nobody really knew what was happening, you could see the confused looks on people faces. After the second tremor I decided to get out of the building and head into open space. That is where I phoned my flatmate, who was at home, to see if anything had come up on the news about the incident - by which time reports where coming through that it was a tremor. It was the first tremor I have ever experienced and quite frankly I hope it is the last.
Gary Fairhurst, England

It was a little bit disconcerting to say the least - what fun!

K Wright, Manchester

I live close to BBC Manchester, the second of the tremors seemed worse than the first, simply because it occurred twice in a matter of seconds. Our tower block of 10 storeys shook like it was landsliding into the nearby river ! It was a little bit disconcerting to say the least - what fun!
K. Wright, Manchester

After the quake finished the building just carried on swaying.
Alex Bailey, UK

I was at work when I felt the second earthquake at approx 1.45pm. Everyone else in the office felt it as well (apart from one person who was standing up at the time - the rest of us were sitting down). It was quite scary, we thought a lorry had hit the front of our building! Within a couple of minutes we looked on the BBC website and saw that it had in fact been an earthquake. How exciting!!

The one this morning was more like a wobble than a quake, but the two at lunchtime were really shocking

It was not being in control that really scared me

I was stood up at my desk, and my body started to shake, I thought I was having a panic attack, then I realised what it was. It was not being in control that really scared me.

I was in uni and felt the ground shake; it's so bizarre and scary when you haven't got a clue what's going on. The building was evacuated for half an hour. Nobody knew what was happening. At first we thought it was a bomb!
