Scientists can collect measurements of vibrations occurring inside the Earth using a seismograph. A seismograph is an instrument designed to record and measure seismic waves resulting from earthquakes, volcanic activity, or other sources of ground vibrations. It consists of a stationary frame and a suspended mass, and when seismic waves pass through the instrument, the mass remains relatively still while the frame moves, causing a pen or stylus to trace the vibrations on a paper or digital recording device. These recordings provide valuable information about the timing, intensity, and location of seismic events, helping scientists understand the Earth's interior structure, tectonic activity, and earthquake hazards.
