Types of earthquake sequences

By California Volcano Observatory
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.
