which strategy do geologists use to locate the center of an earthquake?\no they only analyze local data.\no they collect data from seismographs.\no they measure arrival times of surface waves.\no they draw squares on maps for measurements.
Answer
Brief Explanations:
Geologists use seismographs to record seismic waves during an earthquake. By collecting data from multiple seismographs located at different places, they can triangulate the epicenter (center) of the earthquake. Analyzing only local data is not sufficient. Measuring arrival times of surface - waves is part of the data collection but not the whole strategy. Drawing squares on maps for measurements is not a standard method for locating earthquake centers.
Answer:
They collect data from seismographs.
