seismograph
Other forms: seismographs
A seismograph is an instrument scientists use to measure the strength of an earthquake.
Geologists or geophysicists who study earthquakes are called seismologists, and the tool that helps them study the shaking of the ground is called a seismograph or seismometer. It is usually installed at ground level or slightly underground, and it measures how intense an earthquake is. Seismograph comes from the Greek words seismos, "earthquake," and graph, "writing."
