The United States Geological Survey has recorded the largest number of earthquakes on record in the country’s Rocky Mountains, a record that has not been broken in decades.
The quake occurred Thursday near the town of Hinton, Oklahoma, about 140 miles north of Oklahoma City, the U.S. Geological Survey said.
The quake measured 5.3 on the Richter scale.
Scientists say there is no consensus as to why this particular earthquake struck, with many theorizing the area may have been at the top of a fault line.
However, others point to an unusual series of tremors in the area around the town in recent years, including one in February that measured a magnitude of 6.7.
The U. S. Geological survey also says the quakes in the past week were larger and were centered in a region that sits close to the boundary of the Oklahoma and Missouri Rivers.
Geological Society issued a statement Thursday saying the new quake was the most powerful earthquake recorded in the United States.
