The U.S. Geological Survey (USGS) monitors and reports on earthquakes globally, providing data such as magnitude, location, depth, and time of occurrence. Magnitude, a measure of an earthquake's size, is determined from seismic waves recorded by seismographs. The location indicates the epicenter, the point on the Earth's surface directly above where the earthquake originates, and depth refers to how far below the surface the earthquake occurred.
