Earth shakes unnoticed

Thursday, January 25, 2007

Local residents weren't shaken up during a small earthquake Jan. 17 centered near Ash Flat.

According to a United States Geological Survey Web site, the quake began at 5:06 a.m two miles northwest of Ash Flat and five miles southwest of Cherokee Village. The quake lasted just a few short moments, but measured 2.5 on the Richter scale in magnitude, according to the site.

The area is known as the Ozark Dome Region of the Illinois Basin. The dome stretches from Indianapolis to St. Louis to Memphis. The region also borders the New Madrid seismic zone, which is considered to be the source of the quake, the site said.

An earthquake also struck Jan. 13 near New Madrid, Mo. The quake hit at 1:04 p.m. and measured 1.8 on the Richter scale. The epicenter was four miles from Marston, Mo., and six miles south of New Madrid, the site said.
