Graph showing earthquake magnitudes and equivalent energy release
Illustrations
A simplified set of plots of earthquake sequences, with magnitude on the vertical and time on the horizontal axis. In the top plot, dots show earthquake magnitude starting off large and getting smaller and less frequent over time. On the bottom plot, earthquake magnitudes and times don't follow any particular pattern but happen in bursts.

This map shows the Mono Lake - Long Valley region and part of the Sierra Nevada to the south. The landscape is shown in shades of gray while earthquakes are depicted with orange dots scaled according to the earthquake's magnitude. Black lines indicate where seismic monitoring boxes are drawn around Mono Lake, the Long Valley Caldera, the Sierra Nevada, and Mammoth Mountain.
