Residents in Helston reported feeling tremors at 17:00 BST on Thursday. No structural damage was reported.
The BGS confirmed the "seismic event" and has urged affected people to tell them how they experienced it.

Stuart MacKenzie, from Leedstown, said he had been upstairs in his house when he heard a sound like "thunder or a large lorry going by".
"I also was aware of the bit of movement because I heard the room creak a bit," he said.
Radio Cornwall producer Rebecca Wills, from Helston, added: "There was a low rumble and there was like a sonic boom.
"The whole of the house shook and everyone kind of looked at each other and thought 'what on earth was that?'"
