Question

Explain how we know the history of earthquakes in the Pacific Northwest. How is this evidence of past earthquakes used to predict future earthquakes?

Answer 1

Answer:Scientists estimate earthquake probabilities in two ways: by studying the history of large earthquakes in a specific area and the rate at which strain accumulates in the rock. Scientists study the past frequency of large earthquakes in order to determine the future likelihood of similar large shocks
