seismometers
Earthquake measuring devices
Seismometers are instruments that detect and measure ground vibrations, most notably those caused by earthquakes.
The device records the intensity, duration, and direction of seismic waves as they pass through the earth, producing data that scientists use to determine an earthquake's magnitude and locate its epicenter.
Networks of seismometers positioned around the globe allow for real-time monitoring of seismic activity.
The seismometers picked up tremors from an earthquake three hundred miles away.
