seismographs
Ground movement recorders
Seismographs are instruments that detect and record vibrations in the earth, especially those caused by earthquakes.
A seismograph produces a seismogram—a visual record of ground motion over time.
The data helps scientists measure earthquake intensity, locate epicenters, and study the earth's interior structure.
The seismographs registered a 5.2 magnitude tremor.
