How are earthquake predictions made
WebWhat is long-range earthquake prediction? Long-term forecasting is based mainly on the knowledge of when and where earthquakes have occurred in the past. … Through study of the offsets in sedimentary layers near fault zones, it is often possible to determine recurrence intervals of major earthquakes prior to historical records. WebThese predictions are based on extensive research of aftershock patterns. Seismologists can make a good guess of how an earthquake originating along one fault will cause additional earthquakes in connected faults. Another area of study is the relationship between magnetic and electrical charges in rock material and earthquakes.
