How does a seismograph record an earthquake?
ScienceEarthquakes
Quick Answer
A seismograph measures ground motion with a suspended mass and records it as a trace on paper or a digital display. The resulting seismogram shows the shaking’s strength and timing.
The Full Story
A seismograph works because a heavy mass tends to stay still while the ground around it moves. Relative motion between the mass and the instrument is converted into a visible or digital record called a seismogram. Seismologists use these records to determine an earthquake’s arrival time, distance, and magnitude. Modern networks of seismographs around the world help detect even small quakes and track seismic waves through Earth’s interior.
