1 Mar 11 - The central Arkansas town of Greenbrier has been plagued by more than
800 small earthquakes in recent months, says this article in the Kansas City
Star. Last night residents awoke to the largest quake to hit the state in 35
years.
The magnitude 4.7 temblor - also felt in Oklahoma, Missouri, Tennessee and
Mississippi - was centered just northeast of Greenbrier, about 40 miles north of
Little Rock, in what is now being called the Guy-Greenbrier earthquake swarm.
"The earthquake activity varies each week, though as many as nearly two dozen
small quakes have occurred in a day," says journalist Sarah Eddington.
"Researchers are studying whether there's a possible connection to the region's
natural gas drilling industry.
"A six-month moratorium was established in January on new injection wells in the
area to allow time to study the relationship - if any - between the wells and
the earthquakes."

"I personally find this interesting since new
zealand started having earthquakes last september totalling over
5,000," says James, "and since last september this region of
arkansas has had 800." |

I'm with you, James. With all of the earthquake
activity in New Zealand (that also began in September), I'm inclined
to doubt the drilling connection.
