Here is an animated view of the New Madrid Seismic Zone with the earthquakes played back over time. This makes it easy to see clusters of quakes happening in quick succession. The quake data is from the Center for Earthquake Research and Information at the University of Memphis, and it spans the time period from June, 1974 through July, 2011 in 3 minutes and 47 seconds. That’s almost too much time compression, but it works.
Update: Here is a newer version of the video encoded so that YouTube likes it much better. Production notes below.
