Series of earthquakes hit Oklahoma

Series of earthquakes hit Oklahoma

A series of earthquakes hit parts of Oklahoma on November 11, 2016, just days after damaging M5.0 in Cushing, north-central Oklahoma, one of the world's key oil hubs.

Between 00:08 and 15:49 UTC today, USGS registered a total of 6 earthquakes with magnitudes between 2.5 and 3.0.

Today's quakes come just 4 days after a sharp M5.0 earthquake hit the city of Cushing in Payne County, a key world oil hub, at 01:44 UTC on November 7, 2016. That quake, however, was the strongest after M5.8, the strongest earthquake in Oklahoma's history, hit Pawnee and forced shutdowns of 37 oil wells.

Oklahoma governor Mary Fallin declared a state of emergency for Payne County on Tuesday, November 8. The authorities shut down 7 more disposal wells and reduced volumes of 47 others.

In recent years, Oklahoma has had thousands of earthquakes. Nearly all have been traced to the underground injection of wastewater left over from oil and gas production.

Over the past 7 days, Oklahoma and neighboring Kansas were hit by 32 earthquakes, according to the USGS, with magnitudes between 1.4 and 5.0.
