Oklahoma Earthquakes

A slew of small earthquakes have rattled parts of the Oklahoma City Metro.

A series of earthquakes rattled parts of central Oklahoma on Saturday. There have been no reports of damage or injuries, but the quakes were a rude awakening to some in the northeastern suburbs of Oklahoma City.

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.

Hurricane Cristobal ceased to be at 11 am EDT on Friday, as the storm completed its transition to a powerful extratropical storm. With Cristobal's transition to an extratropical storm and the demise of the Eastern Pacific's Tropical Storm Marie earlier today, there are now no named tropical cyclones anywhere in the world--an unusual situation for what is traditionally one of the busiest days of the Northern Hemisphere's tropical cyclone season.

By Angela Fritz

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
