Which action would geologists take in order to determine the Richter magnitude of an earthquake?
A) analyze seismic instrument readouts
B) take core samples at several spots and from different distances from the epicenter
C) assess financial costs of rebuilding roads, buildings, and public areas in the quake zone
D) interview people who experienced the quake

Question

Quizplus · Accepted Answer

Geologists would analyze seismic instrument readouts, such as seismograms, to determine the Richter magnitude of an earthquake. Seismograms record the seismic waves generated by the earthquake and allow geologists to measure the amplitude and duration of the waves, which are used to calculate the magnitude. Taking core samples, assessing financial costs, or interviewing people would not provide information on the Richter magnitude of an earthquake.
