Earthquake Shakes Oklahoma City

A magnitude 5.6 earthquake has struck Oklahoma City along with other surrounding communities.  There have numerous smaller aftershocks.  Here is a map of the general area, with recent earthquakes depicted by the squares:

This image will not update as new earthquakes occur.  The size of the squares depicts the intensity of the earthquake, and color shows the time.  We can see a large square near the middle, with numerous smaller squares surrounding it.  This is the big quake and the smaller quakes, respectively.  Here is a map depicting where the larger earthquake was felt:

It spreads out far, with people near Milwaukee reporting feeling this one.  This is usually the case for areas east of the Rockies.  While earthquakes like this don't occur often, the shaking can spread far and wide due to the flat land.  The opposite is true in areas west of the Rockies, where earthquakes occur often, but can't spread out as far due to the mountainous landscape.  An earthquake of this intensity in this region is extremely unlikely to occur again in the near future (unless this is a foreshock to an even bigger quake), but small aftershocks should continue for a while.  Stay tuned!
