Relative annual energy release from earthquakes, magnitude 6 or greater, 1900-2010. Estimated total annual earthquake energy release (magnitude 8 earthquake = 1 = 1,000 magnitude 6 earthquakes) in red; 7-year average in grey.Of the total energy released in earthquakes, 12 percent comes from intermediate earthquakes—that is, quakes with a focal depth ranging from about 60 to 300 km. About 3 percent of total energy comes from deeper earthquakes. The frequency of occurrence falls off rapidly with increasing focal depth in the intermediate range.

Magnitudes are usually determined from measurements of an earthquake's seismic ...Earthquakes based on the depth of focus. The earthquakes are divided into three zones: shallow, intermediate, and deep based on their depth which range between 0 – 700 km. Shallow earthquakes have a focus 0 – 70 km deep.
