Underwater earthquakes occur quite often but it has to have some specific qualities to create a full on tsunami. People in Rterg office gets all the seismic data from all over the world and analyze it instantly to find out if the earthquake matches with the standards. So the results are much precise. The old tsunami warning system works on two phases: detecting seismic movement and then detecting wave, there is a tsunami if there is a match but it is relatively slower.
