Earthquake maps and graphs

This is a map of the Apparent Intensity of the 1906 San Francisco earthquake using the Rossi-Forel scale.

These seismic readings from around the world taken in 1906 are from the same San Francisco earthquake as above. It's interesting to see which world locations were able to register the event.

This, by the way, is the state San Francisco was left in after said quake. (Youtube).
