WebEarth scientists can gather data at key sites along sections of a fault to figure out the past timeline of earthquakes at each spot. This type of research is called paleoseismology (“paleo” means old, and “seismology” is the study of earthquakes, so paleoseismology is the study old earthquakes). The basic assumption that ...

Webb. Geologists use seismometers to measure seismic waves. The amplitude of the seismic wave tells the size of the paleoearthquake. c. Geologists make computer models to figure out how frequently large earthquakes happened in the past. Models are always correct. d. Geologists study folded rocks and the tall mountains.
