Oklahoma earthquakes, November 5-7 2011 and historical

ANN ARBOR USA, November 5-7, 2011 (Vacuum News) – There were a series of earthquakes in Lincoln County, Oklahoma, but we didn’t feel them here in Ann Arbor, Michigan.

Some maps and news from people who did feel the quakes follow. The data here are preliminary, and you’ll want to go to the USGS page for the Oklahoma quake for details, and Oklahoma earthquake history to figure out how normal this is. The Oklahoma Geological Survey is likely to also have excellent data.

News coverage from the New York Times quotes Austin Holland, a research seismologist with the Oklahoma Geological Survey; Don Blakeman, a geophysicist at the National Earthquake Information Center; and Justin Reese, who runs the Boomarang Diner in Chandler, Oklahoma.

The earthquake, originally reported at magnitude 5.2 and then upgraded to 5.6, was said to be felt [as far away as Milwaukee] – a claim which is being tested and that I haven’t confirmed. Additional aftershocks were reported; the map is by Dawn Endico using the Google Maps API. Earthquake data provided by the U.S. Geological Survey on Mon, 07 Nov 2011 01:14:04 GMT.

Damage to homes in the area has been reported to the Lincoln County Emergency Management system on Facebook.

Another map, this one showing historical patterns; the red marks are quakes. The source document gives more seismic data.

    “We don’t normally feel earthquakes, it was shocking,” said study co-author Katie Keranen, a seismologist at Oklahoma University.
    Now, a new study published March 26 in the journal Geology confirms that wastewater injected into the ground after oil extraction caused the quake. The quake is the largest wastewater-induced earthquake ever recorded.
    Ever since wastewater injection was linked to a series of small quakes around Denver, Colo., in the 1960s, scientists have known that oil extraction could trigger temblors. When oil is extracted from the ground, lots of water, dubbed “wastewater,” comes up as well. So oil companies sometimes pump the water back into the well, where it fills porous spaces within the rocks, Keranen said.
