Kenneth Davis has been busy Visualizing One Hundred Years of Earthquakes. He has created three different maps from the data to show earthquake activity through time, a heat-map of all quakes over the last one hundred years and a depth map of the quake data.
The animated Torque powered map shows a marked increase in earthquakes after the 1950's. This isn't a result of more earthquakes but due to the ever increasing improvements in measuring and recording seismic activity.
The heat-map provides a neat overview of the fault lines in the tectonic plates and where those faults have caused the most seismic activity. The depth map reveals the geometry of subduction zones, where two tectonic plates are colliding and one plunges beneath the other.
