SPARKS, Okla. (AP) — Clouds of dust belched from the corners of almost every room in Joe Reneau's house as the biggest earthquake in Oklahoma history rocked the two-story building.
The magnitude 5.6 earthquake and its aftershocks still had residents rattled Sunday.
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.
Geologists now believe a magnitude 4.7 earthquake Saturday morning was a foreshock to the bigger one that followed that night. They recorded at least 10 aftershocks by midmorning Sunday and expected more. Two of the aftershocks, at 4 a.m. and 9 a.m., were big, magnitude 4.0.
Scientists are puzzled by the recent seismic activity. It appeared the latest quake occurred on the Wilzetta fault, but researchers may never know for sure. Earthquakes that hit east of the Rocky Mountains are harder to pinpoint because the fault systems are not as well studied as major faults like the San Andreas in California.
Arkansas also has seen a big increase in earthquake activity, which residents have blamed on injection wells. Natural gas companies engaged in hydraulic fracturing, or fracking, use fluid to break apart shale and rock to release natural gas. Injection wells then dispose of the fluid by injecting it back into the ground.
There are 181 injection wells in the Oklahoma county where most of the weekend earthquakes happened, said Matt Skinner, spokesman for the Oklahoma Corporation Commission, which oversees oil and gas production in the state and intrastate transportation pipelines.
But natural gas companies claim there is no proof of a connection between injection wells and earthquakes, and a study released earlier this year by an Oklahoma Geological Survey seismologist seems to back that up. It found most of the state's seismic activity didn't appear to be tied to the wells, although more investigation was needed.....snip~
Scientists don't know the reason why. Due to non-sufficent studying of the Wilzetta Fault. From 50 to over a Thousand. Arkansas with increased seismic activity. We are starting to see and hear more and more about them. Also Seismic Activity has increased the World over. Earthquakes where none were felt before. Does anyone think this may have to do with the Polar Shift?
Note if an earthquake of anything over a 4.7 hits Yellowstone park it will cause that Supervolcanoe to blow. Already they have been recieving the tremors. Here in the Midwest We also have been hit with Shocks. Think our media and government will tell people if it does happen to stir the Supervolcano In Yellowstone Park? http://politirant.com/Smileys/oldrant/blob8.gif http://politirant.com/Smileys/oldrant/blob6.gif
