This pie chart shows the 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. M_w designates an earthquake's magnitude on the moment magnitude scale.
