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.
