Comparison of Recent and Historic Earthquakes by Energy ReleaseThis animation compares the relative “sizes” of recent and historical earthquakes. Each circle’s area indicates relative energy release, color indicates tsunami potential (see http://ptwc.weather.gov/ptwc/about_messages.php), and labels indicate each earthquake’s moment magnitude (according to USGS/NEIC), location, and the year they happened.
