[quote:Watcher of the ETSZ 939683:MV8xMDQ0OTY1XzE2NTY0MTQ1X0I0NDFFRTRB] This recent story summarizes the 3 recent East Tennessee earthquakes that I posted about previously... [b][u]Third Earthquake Since Tuesday Hits East Tennessee[/u][/b] Posted: Apr 22, 2010 10:08 AM MARYVILLE, Tenn. – Residents of Blount County in East Tennessee have experienced their third earthquake in less than 48 hours. The U.S. Geological Survey reported the quake at 10:14 p.m. EDT Wednesday, measuring [b]2.6[/b] on the Richter scale. Over 400 people reported feeling the quake on their website, usgs.gov. WVLT in Knoxville reported several emails and calls from residents who described it as a "big jolt" that shook their houses. The earthquake was centered about two miles west-southwest of Maryville with a depth of 1.1 miles. Officials with the Blount County emergency dispatch center told WVLT the quake prompted several calls, but there were no reports of damages or injuries. The earthquake was the third to strike the area since Tuesday morning, when a [b]3.3[/b] magnitude earthquake woke some East Tennessee residents. The U.S. Geological Survey reported a small [b]1.6[/b] earthquake just five minutes later. [u]The epicenters were all within a half mile of each other.[/u] Kristin Parker with the Tennessee Emergency Management Agency in Nashville said there were no reports of injury or damage from the larger quake, but said the agency received a lot of phone calls reporting the shake. Some reported noises that they at first thought was thunder. One man said he was walking the family dog when he felt the earth shake. [b]He said his wife thought he had run into their house with his truck.[/b](LOL) A person in Alcoa said the house shook and the windows rattled for about five seconds. http://www.newschannel5.com/Global/story.asp?S=12355697 Actually, as I mentioned earlier, this area is actually considered the ETSZ (Eastern Tennessee Seismic Zone) rather than the New Madrid Fault... [b][u]Eastern Tennessee Seismic Zone[/u][/b] The Eastern Tennessee Seismic Zone is a geographic area subject to frequent small earthquakes which stretches from northeast Alabama to southwest Virginia. The Eastern Tennessee Seismic Zone (ETSZ) is also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone. The area is one of the most active earthquake zones in the eastern United States. http://en.wikipedia.org/wiki/Eastern_Tennessee_Seismic_Zone So, I have become the "Watcher of the ETSZ" for the future life of this thread ;-) [/quote]

Tremors In Tennessee Could Mean An Active New Madrid Fault Line
January 27, 2010 03:11 PM EST
Experts say that the New Madrid fault is active which could result in an earthquake. Recent tremors in West Tennessee could mean an earthquake in the future on the New Madrid fault line. Earthquakes that occur on the New Madrid fault can affect areas such as Illinois, Missouri, Kentucky, Indiana, Arkansas, Tennessee and Mississippi. The fault has produced four of the largest North American earthquakes in history.
The four earthquakes that occurred in this region happened between 1811 and 1812. The magnitude of the quakes was in excess of 8.0.
The recent tremors in the area seem to mean that this fault is active and should be watched carefully.
