Oklahoma was rocked by seven small earthquakes in a span of about 14 hours over the weekend, the U.S. Geological Survey said.
Three quakes hit between Saturday evening and Sunday morning, centered in the areas of Guthrie, Jones and Langston, and ranging between 2.6 and 2.9 in magnitude. They followed four larger temblors earlier on Saturday, including one near Langston shortly after noon that clocked in at 4.3 on the Richter scale.
