Oklahoma, which has had 133 quakes of magnitude 2.5 or greater in the last 30 days, was rocked on April 7 by a 4.3 magnitude earthquake in the central part of the state, according to the Oklahoma Geological Survey.
The quake struck shortly after 11 a.m. and was centered near Langston. It was felt widely through the central part of the state, including Oklahoma City. There are no immediate reports of damage.
Austin Holland with the Oklahoma Geological Survey says the quake had a preliminary depth of three miles.
The U.S. Geological Survey, however, reported that the quake had a 4.0 magnitude. Quake magnitudes are often revised after data is reviewed.
Langston has been the site of several earthquakes over the past few months. Three rocked the area over the weekend, including one that the USGS measured as 4.0 magnitude.
