There is an earthquake
The force or category of an earthquake is typically measured using the Richter scale or the Moment Magnitude scale (Mw). The Richter scale quantifies the seismic energy released at the earthquake's source, while the Moment Magnitude scale provides a more accurate measure of the earthquake's size, especially for larger events, by considering the fault area and the amount of slip. Seismographs detect and record the vibrations generated by the earthquake, which are then analyzed to determine the magnitude. Additionally, the Modified Mercalli Intensity scale assesses the earthquake's effects on people, structures, and the Earth's surface.
