Amazing. During the Venezuela earthquake, Google used its Android phone network’s accelerometers as mini-seismometers.<br>When many phones detected initial seismic waves (faster P-waves), the system analysed the data, estimated the quake's location/magnitude, and pushed alerts to people phones to prepare for the more destructive waves to follow.<br>Google's system sent warnings to 11.4 million people in Venezuela.<br>Even if it only a tiny fraction of these alerts saved lives, Google may have saved tens of thousands of people and prevent a similar number of injuries.<br>Goes to show you what technology can do and why people like myself celebrate and cherish human progress.<br>Subscribe to Risk & Progress for more.
