Quakes shaking up some Oklahomans

OKLAHOMA CITY — The power and frequency of earthquakes in Oklahoma have been increasing, but the Legislature has done little to try to curb the temblors that scientists have linked to the underground disposal of oil and gas drilling wastewater.

Some residents have been turning up at town-hall meetings and legislative hearings to call for state leaders to address the problem.

According to the U.S. Geological Survey, Oklahoma this year has already had more than 90 earthquakes of magnitude 3.0 or greater, which is generally when most people start to feel them. The town of Fairview, in northwest Oklahoma, has been hardest hit, but several large quakes also have rattled the suburb of Edmond, including a 4.3-magnitude quake on Dec. 29 and a 4.2 temblor a few days later.
