whaT DOes a seismograph record

Answer 1

A seismograph records seismic activity, specifically the vibrations or seismic waves caused by earthquakes or other sources of ground motion. It measures the amplitude, frequency, and duration of these waves, providing data that can be used to determine the magnitude and location of an earthquake. Seismographs can also record other types of ground motion such as volcanic eruptions, landslides, and even human activity.
