“Which device is used to measure earthquakes?”

"A seismograph is a critical device utilized to measure earthquakes by detecting and recording ground motion. It captures seismic waves generated by tectonic activity enabling scientists to determine an earthquake’s magnitude location and depth. The instrument’s precise measurements are essential for monitoring seismic events assessing risks and ensuring public safety. Seismographs play a vital role in earthquake-prone regions supporting early warning systems and disaster preparedness. By analyzing seismic data researchers enhance understanding of earth’s geophysical processes contributing to advancements in geology and hazard mitigation strategies for global communities."
