            English: This pie chart shows how the total  seismic moment released by earthquakes over the period 1906-2005 was distributed, with the largest individual earthquakes (left side) and groups of earthquakes (right side). The thin sliver of the 1906 San Francisco Earthquake is also depicted for comparison purposes. Mw designates an earthquake's magnitude on the  moment magnitude scale.Earthquakes referenced in this chart:
