Scientists can collect measurements of vibrations occurring inside Earth using a seismograph. A seismograph is an instrument that detects and records the ground motion caused by seismic waves, which are generated by earthquakes, volcanic eruptions, and other sources of underground activity. By analyzing the data recorded by a seismograph, scientists can study the intensity, frequency, and duration of seismic events, as well as the location and depth of the source. This information is valuable for understanding the Earth's structure, studying plate tectonics, detecting and monitoring earthquakes, and assessing the potential hazards associated with volcanic activity.
