A preliminary report from the U.S. Geological Survey shows that a 2.5 magnitude earthquake struck 24 miles northwest of Healdton, in south-central Oklahoma, at 10 a.m. Tuesday.
It had a depth of 3.1 miles.
Another earthquake centered near Edmond struck at around 3:45 p.m. Tuesday. The 2.8 magnitude quake had a depth of 3.1 miles and was located 4 miles southeast of Edmond and 11 miles northeast of Oklahoma City.
Following a rash of earthquakes, a state lawmaker says he plans to file a bill to require insurance companies to notify Oklahomans whether their policies cover property damage caused by earthquakes.
Rep. Mike Shelton of Oklahoma City filed a bill last year that would have required insurance companies to notify Oklahomans who are purchasing or renewing an insurance policy whether the policy covers losses caused by earthquakes. Shelton says the measure was opposed by the insurance industry and died in a House committee.
Oklahoma's insurance commissioner is advising residents to purchase earthquake insurance after a national report suggested that seismic activity in the central part of the state is here to stay.

Morning recess at St. Augustine Catholic School in Culver City, Calif., is like recess in many other schools. Children run and play in the afternoon sun. But nearby, away from the basketball hoops and the games of tag, the staff is preparing.
Next to the playground sits a cargo container full of supplies: water, duct tape, an axe, a shovel and a generator along with gasoline. All of these supplies are here just in case the freeways are cut off or the power goes out — in case there is a major, destructive earthquake.
A new study shows yet another link between oil and gas drilling and manmade earthquakes in Texas. The report, by scientists at the University of Texas at Austin, says that a recent string of quakes in the Eagle Ford Shale formation of South Texas are mostly a result of oil and gas drilling.
The Oklahoma Geological Survey has begun work on plans to reduce the risk of oil-field work causing earthquakes.
The Tulsa World reported Saturday that a summary report says the risk of oil-field caused earthquakes is small — and can be reduced further with "appropriate industry practices" involving injection disposal wells.
