All warning systems work in the same general way. First, a network - TopicsExpress

All warning systems work in the same general way. First, a network of broadband seismometers detects the seismic waves generated by an earthquake, which travel at speeds of several kilometres per second. When several seismometers have detected the seismic waves, the location and approximate magnitude of the earthquake can be computed. If the epicentre is under water and the magnitude large (greater than 6.5 on the Richter, or moment magnitude, scale) a tsunami bulletin, watch or warning is issued to local communication centres, ideally within three minutes of the earthquake. If the epicentre is nearby and the probability of a tsunami is high, evacuation procedures will be initiated immediately.
