Which instrument records tremors?

Explanation:
Recording tremors is what a seismograph does. It’s designed to detect and record ground motion from earthquakes and other seismic activity. Inside a seismograph, a mass on a spring tends to stay still while the ground moves, and the frame moves with the ground; the recording element traces this relative motion, producing a seismogram that shows when the tremor happened and how strong it was. Barometers measure air pressure, useful for weather changes; thermometers measure temperature; anemometers measure wind speed. So the instrument that records tremors is the seismograph.
