Big quake follows increase in Oklahoma rumblings


The magnitude 5.6 earthquake and its aftershocks still had residents rattled Sunday. No injuries were reported, and aside from a buckled highway and the collapse of a tower on the St. Gregory's University administration building, neither was any major damage. But the weekend earthquakes were among the strongest yet in a state that has seen a dramatic, unexplained increase in seismic activity.

Oklahoma typically had about 50 earthquakes a year until 2009. Then the number spiked, and 1,047 quakes shook the state last year, prompting researchers to install seismographs in the area. Still, most of the earthquakes have been small.

Scientists say they have no explanation for the quakes. They happened along an ancient fault, although it's not clear yet whether shifting along the fault is what caused them, Earle said. One reason earthquakes are hard to predict in Oklahoma is that the state sits over a series of smaller ancient faults, rather than a major fault, such as California's San Andreas Fault, he said.

Needless to say, also many questions about Injection wells/fracking --

However, the melting of the glaciers is lessening/increasing pressures on the tectonic plates

which causes earthquakes.

Earthquakes in turn generte new volcanic activity.

1. Are they even doing any fracking in that area? Or is it that an ancient fault line acting up? nt

4. Answer: no and yes

It's the result of a geologic event that took place millions of years ago. It's been going on since then as well.

Dr. Tapp says you can blame this on events that first happened 300 million years ago. He says when the Wichita, Arbuckle, and Ouachita Mountains were formed, the ground rose up. But just north of the Wichita and Ouachita Mountains the ground sunk and formed the Anadarko and Arkoma basins.

This action caused a fault line to form between the two basins, that fault line is where the epicenter to these large earthquakes is located. He says the earth is still trying to relieve pressure from those long ago geologic events.

"So we just seem to be relaxing, just slightly, over time," he said.

One thing he's positive of: this mess was not caused by fracking.

"There's no way that this particular fault or this particular earthquake could have been activated by oil field activity; there's just no evidence of that," said Dr. Bryan Tapp, a structural geologist.

5. 181 sites in that county alone ...

2. it's god telling warning them to quit being so...OKKKlahoman lol nt

3. Must be warning about Sharia law

I'm sure if they post the 10 Commandments on every vertical surface, they'll be fine.
