Re: [Geology2] Geologist: worldwide seismic uptick responsible for Oklahoma earthquake swarm



He needs to write a paper and have it go through peer review.... a luncheon is a start but not a finish.

Geologist: worldwide seismic uptick responsible for Oklahoma earthquake swarm

Oklahoma quakes not 'unprecedented,' according to Glen Brown

Jul 23, 2014

OKLAHOMA CIT —A geologist representing the oil and gas industry says his business is not to blame for the uptick in Oklahoma quakes.

Glen Brown, a geologist with Continental Resources, made the case Wednesday to hundreds of geologists attending a luncheon hosted by the Oklahoma City Geological Society.

Brown argued earthquakes swarms naturally come and go and right now the world is experiencing more quakes. He maintains that's why Oklahomans are feeling more.

"Oklahoma has gone through an unusual period of earthquakes," Brown told a packed room at the Oklahoma History Center. While Brown agrees seismic activity in the last few years in Oklahoma is unusual, he believes it is not unprecedented.

"What maybe (is) unprecedented here is our ability to observe and measure the quakes," Brown stated.

Brown points to similar seismic activity in Oklahoma in the 1950s. Other than the 5.6 quake in Prague in 2011, the largest quake on record in Oklahoma is a 5.5 in El Reno in 1952. Brown says that quake was one of many in the '50s, just like the Prague quake is one of many in the last few years.

Brown is quick to point out back in the 1950s, there were no wastewater injection wells in Oklahoma to cause quakes. He also contends the quakes in Oklahoma today are deeper in the earth than injection wells can reach.

Separating his hands, Brown told the crowd, "You're injecting up here and the earthquakes are down here, let's talk about something that's possible."

So what's the reason for the surge in quakes in Oklahoma? Brown believes it's a surge in worldwide seismic activity including recent monster quakes in Japan and Chile. Brown says back in the 1950s the world was also going through a similar significant seismic period.

Brown's statements bring many questions, but KOCO did not get the chance to ask them Wednesday. He left the luncheon without speaking to the media.
