Relative annual energy release from earthquakes, magnitude 6 or greater, 1900-2008

Estimated total annual earthquake energy release (magnitude 8 earthquake = 1 = 1,000 magnitude 6 earthquakes) in red; 7-year average in grey.

Annual earthquake-related fatalities per million population, worldwide, 1900-2008

Annual earthquake death rate per million population in red; smoothed rates in grey (specifically, linear smoothing with 7-year Hann window). Note logarithmic scale.
