A series of earthquakes have been plagueing the Oklahoma state on Saturday November 5th, 2011 and on Sunday November 6th, 2011. The earthquakes started with smaller trembles and eventually increased to a 5.6 magnitude at 10:53pm CST. The OK earthquake 5.6 magnitude is the largest earthquake since records have been kept on earthquake activity.
The USGS first reported the earthquake at a 5.2 magnitude quake but soon after upgraded this to a 5.6 magnitude. The 5.6 tremblor was about 44 miles East-Northeast of Oklahoma City and could be felt as far as Kansas City, Southeast Nebraska and through many parts of Missouri.
Damaged roads, highways, homes, buildings and infrastructure have been reported throughout the parts hit by the Oklahoma quake. The Lincoln County Emergency Management has posted messages on Facebook stating, “Very significant damages are being reported in southern Lincoln County.” Highways like the US-62 were crumbled in pieces and one major road was blocked by a boulder that had rolled into the road.
A U.S. Geological Service shake map provided here in our report shows where the epicenter was for this major earthquakes felt on Saturday and Sunday in OK. The center of the quake erupted from Sparks, OK which is between Tulsa, OK and Oklahoma City.
ESPN has some footage of a reporter named Kirk Herbstreit reacting to the earthquake in Oklahoma. Mr. Herbstreit was being questioned during coverage on Oklahoma State’s defeat of Kansas State when his eyes opened wide and his lips pinched together. When it was time for the answer to the question Kirk Herbstreit replied to Chris Fowler he would have to ask the question again because he had just felt an earthquake and saw people in the stadium reacting. You can watch the video of Mr. Herbstreit and Mr. Fowler below.
