More than 2 dozen quakes shake Arkansas in a week

LITTLE ROCK, Ark. (AP) - More than two dozen earthquakes have rumbled through Arkansas in the past week.

Many of the temblors have been too small for people to notice, let alone cause injuries or property damage.

But a couple of residents reported feeling a 3.4 magnitude quake north of Morrilton overnight Friday.

The area north of Morrilton is 1 of 3 spots hit by quakes in recent days. Earthquakes have also shaken an area south of Clinton and another area east of Cave City.

Scott Ausbrooks of the Arkansas Geological Survey says the quakes east of Cave City are believed to have occurred naturally.

But officials aren't sure what is causing the temblors in the other two areas.

The latest round of quakes comes about two years after hundreds of earthquakes shook central Arkansas.
