How do scientists mesure earthquacks?

Answer 1

Scientists measure earthquakes using instruments called seismometers or seismographs, which detect and record the vibrations generated by seismic waves. These instruments capture the intensity, duration, and frequency of the ground motion, allowing scientists to analyze the earthquake's magnitude and location. The moment magnitude scale (Mw) is commonly used to quantify the size of an earthquake, providing a standardized measure based on the seismic energy released. Additionally, data from multiple seismometers can be used to triangulate the epicenter of the earthquake.
