Prehistoric Earthquakes May Be Studied By

Prehistoric earthquakes may be studied by:

A) digging trenches along a fault in order to map the offset of layers of sediment and soil to provide a timeline for interpreting when the fault moved
B) using seismic recording stations to gather data about P-waves, S-waves, and surface waves so that earthquake magnitude can be determined
C) looking at seismograms in order to measure P-S time to determine the epicenter of the earthquake
D) using satellite data to create an interferogram and show how Earth deformed near the fault rupture
