Earthquakes Rock Oklahoma City Metropolitan Area

iStockphoto/Thinkstock(OKLAHOMA CITY, Okla.) -- A series of earthquakes hit the Oklahoma City area early Tuesday morning.

According to the United States Geological Survey's website, the Oklahoma City metropolitan area was hit by seven seismic events on Tuesday.

The Oklahoma City area is home to multiple fault lines and is prone to earthquake activity. Multiple quakes in succession are also common in the area.

The first quake, measured at magnitude 3.0, struck southwest of Chandler, Okla., at 2:45 a.m. EST.

The next three tremors occurred within 15 kilometers of Luther, Okla., between 2:56 and 3:17 a.m. EST. The second quake, a magnitude 4.3, was the strongest of the day. It was followed soon after by a pair of earthquakes measuring magnitudes of 2.9 and 3.3.

Three additional quakes hit near Luther between 6:00 a.m. and 2:00 p.m.

People in the Oklahoma City area reported being woken up by the tremors, but there are no reports of structural damage. Officials do expect that the foundations of some buildings will have suffered cracks.

USGS Director : "Shame On Us If We Don't Learn From Their Misfortunes" in Japan

NASA via Getty Images(WASHINGTON) -- The director of the U.S. Geological Survey, Dr. Marcia McNutt, told a House Subcommittee Thursday morning there are a lot of lessons to be learned by scientists and by people in the United States from the earthquake and tsunami in Japan.

“Shame on us if we don’t learn from their misfortunes” she told the subcommittee. Testifying before the House Appropriations Committee Subcommittee on Interior Environment, and Related Agencies, McNutt stressed the importance of Japan’s earthquake early warning system saving “thousands of lives”.

McNutt also pointed to Japan’s earthquake engineering. The engineering of the buildings in Japan helped many of the buildings come thru the magnitude 9.0 earthquake.  McNutt told the subcommittee how the tsunami was the real killer in Japan, killing thousands of lives.  “We are much more fortunate than Japan,” she said, that the U.S. does not have many areas that can be affected by local tsunami hazards.

She also told the subcommittee that the United States continues to be on track to develop an earthquake early warning system for California.  But, USGS officials later explained to ABC News that the reality is the U.S. is way behind Japan in developing an earthquake warning system for California.  The U.S. still has approximately two more years before completing a prototype and the completion may be delayed further with expected cuts in the president’s upcoming 2012 budget.
