Oklahoma Earthquakes
A slew of small earthquakes have rattled parts of the Oklahoma City Metro.According to the United State Geological Survey (USGS), the first quake – a 3.7-magnitude – struck about five miles east-southeast of Edmond, around 4:36 a.m. local time.
A 2.6-magnitude quake struck the same area just over an hour later.
Shaking has continued intermittently through the morning. A 2.7-magnitude earthquake struck six miles east-southeast of Edmond at 7:04 a.m. local time and a larger 3.6-magnitude was recorded at 9:19 a.m.
A recently released report from the USGS suggests that the latest series of quakes could be related to an increase in seismic activity dubbed an ‘earthquake swarm.’ According to the report, since 2009, Oklahoma has experienced a dramatic increase in the average number of earthquakes with a magnitude of 3.0 or greater.
The Oklahoma Geological Survey says the on average there are about 50 earthquakes a year in Oklahoma.
