Seismographs. Seismographs are instruments used to measure seismic waves. They measure the vibration of the ground using pendulums or springs. The seismograph principle involves mounting a recording device solidly to the earth and suspending a pen or writing instrument above it on a spring or pendulum.Nepal's National Earthquake Monitoring and Research Center gave a preliminary magnitude of 6.1. The U.S. Geological Survey provided measurements of a 5.2 magnitude with a depth of 24.7 ...There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between the earthquake and the recording seismometer so that the calculated magnitude should be about the same no matter where it is measured.
