Record Quake Strikes Oklahoma November 11, 2011
Quake Map of Oklahoma
Oklahoma’s most powerful earthquake on record damaged more than a dozen homes about 40 miles east of Oklahoma City, and was felt throughout neighboring Kansas, Missouri and Arkansas.

The 5.6 magnitude quake caused roadways to buckle near the epicenter and sent a brick chimney tumbling through the roof of a house.

The shaking was felt for more than a minute, starting Saturday evening at 10:53 p.m. local time.

Wire service reports said the quake was also felt as far away as Illinois, Tennessee and Texas.

Aftershocks kept nerves on edge for three days following Saturday’s initial jolt and a 4.7 magnitude foreshock Saturday morning.

Previously, Oklahoma’s most powerful quake was a magnitude 5.5 temblor in April 1952, according to the Oklahoma Geological Survey.

The agency was rushing to deploy a network of remote seismographs near the epicenter of Saturday's quake so any future shaking could be better documented.
