The everyday tech helping prevent disasters

For International Day for Disaster Risk Reduction, we're finding out how technology can help prevent disasters, save lives and help rescuers. In Argentina, we’ll meet Franco Rodríguez Viau whose family friends lost their home in a fire, inspiring him to find a way of tracking wildfires. He was just a teenager when he began developing an app that combines NASA satellite imagery with other data sources to identify and intercept fires before they become unmanageable. Meanwhile in Colombia, podcasters and sound engineers tell us about using their specialist recording equipment and live analysis of sound to detect breathing and tapping beneath earthquake rubble, helping rescuers locate survivors.
