Seismic waves are recorded in seismometers. The seismometers record ground movements. Seismometers are sensitive enough to record ground movement with a displacement of (3x10 to the power minus 8 meters). The arrival times of millions of data allows seismologists to have a clearer picture of the location and size of sub-surface structures. The result is a 3D image of a slice through the earth that serves as a seismic velocity map. The image shows where seismic waves ...
