The instrument designed to measure earthquakes is called a seismometer. Seismometers detect and record the vibrations caused by seismic waves as they pass through the Earth during geological events like earthquakes. These devices can help determine the intensity, duration, and location of earthquakes, providing essential information for research and safety measures. Modern seismometers have become highly sophisticated, capable of detecting even minor tremors and assisting scientists in understanding Earth’s structure and dynamics. They play a critical role in earthquake preparedness, helping communities respond effectively to seismic events and mitigate potential damage.
