Question

Quizplus · Accepted Answer

The first step in producing a timely warning of a tsunami is the detection of a possible tsunami-producing earthquake. This detection can be done through seismic sensors that are capable of identifying the type of earthquake that can cause a tsunami. Once the earthquake is detected, the calculation of ocean travel times, and the use of tidal gauges and tsunameters can help in predicting the arrival and intensity of the tsunami.
