A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake. If you live in a city, you may have noticed that buildings sometimes shake when a big truck or a subway train rolls by. Good seismographs are therefore isolated and connected to bedrock to prevent this sort of data pollution.
One seismograph is needed to measure vertical motion, and two to record horizontal motion. The two seismographs recording horizontal directions, record in 90-degree angles (Kauffman and Judson 182). Seismographs record in a zigzag trace that shoes the varying amplitude of ground oscillations beneath the instrument.
