Experts leaning toward man made cause of quaking Posted on Thursday, February 14, 2013 at 11:35 am Scientists are meeting today to try to determine what has been shaking Hamblen County recently. “They know activity occurred, however, most of their indicators lean toward a man-made event over a natural event,” said Hamblen County Emergency Management Agency Director Chris Bell. “They know it was felt up into Lonesridge, Va. and they are pulling data from each of their incidents. There is a group meeting today to pull together information and, at this time, it appears to be man made but they can not rule out some type of seismic activity in the earth,” Bell said. The booms that rocked Morristown Tuesday afternoon and night returned again Thursday morning in the Crockett’s Ridge, Country Club Drive area. Hamblen County 911 Director Eric Carpenter said around 10 calls came in reporting shaking, rattling and booming. Bell spoke with Dr. Gary Patterson with the Center for Earthquake Research and Information in Memphis Thursday morning. Bell, said Patterson and his team have met, and as of Thursday morning they are still studying information from charts. “They are still studying information at this point and they can not make an official statement. Gary Patterson said they would give us their unofficial conclusion based on the evidence. Unofficially, they said the other occurrences appear to be man made, based on the evidence they have at this time and they do not appear to be indicative of earthquakes. They are still studying the 9:16 p.m. anomaly,” Bell said. Authorities have said that fracking, explosions, sewer repair work, area construction, the Tennessee Valley Authority, weather, the military and the mine in Jefferson City are likely not the cause either. Historically, “mysterious” booms and ground shaking are not all that uncommon. Between Dec. 4 and Dec. 5 of 2012, five states reported mysterious booms, similar to Morristown’s, within 24-hours. For centuries, booms have been heard in Moodus, Conn. Those booms could be attributed to post glacial rock slabs settling beneath the surface. Many “mysterious” booms reported throughout the country were later identified as earthquakes, sonic booms or meteors while others have gone unexplained. -By Aletheia Davidson, Tribune Staff Writer
MORRISTOWN (WATE) - Officials now say they've confirmed that the source of mysterious booms in Hamblen County as mining or quarry-related activity.
The Center for Earthquake Research and Information told emergency management officials there's only a 5 to 10 percent chance the booms were seismic activity, and much more likely man-made.
Emergency Managment Agency Director Chris Bell says there was no licensed blasting in the Hamblen County area on Tuesday.
10News also confirmed with the area's only quarry, Vulcan Materials, that no blasting happened yesterday.
Patterson says the activity shows up over a large area with sensors reporting vibrations in Copper Ridge, Avondale Springs, Green Top, and Lonesome, VA.

Here is the legend and final mapping.
A's - Morris Town node (mttn)
B's - Hickory node (brbc)
C's - Athens node (athn)
And the map -
Geophysicist Julie Dutton in Denver said the USGS received several phone calls regarding the tremors that were reported around 4 p.m. and 9:30 p.m. Tuesday in Central and East Hamblen County and Morristown.
"It wasn't big enough or we couldn't see it on wave forms to identify it as an earthquake," she said. "It doesn't mean you didn't have one, we just didn't find it on our system."
Dutton said seismographs record earthquakes and personnel use the instruments to look at records to see if an earthquake occurred.
"So far, we've been unable to identify one on our wave forms," she said.

Mayan Calendar didnt calculate for leap year....so its only a rough estimate.
Tennessee has a long, rich, and varied mining history. Historically, Tennessee's most important mining products have been iron, bituminous coal, copper, lead, zinc, and phosphate. Iron ore was the most significant during early settlement years. Interest in the iron ore of the Western Highland Rim dates back to the 1790s and even earlier in the eastern Tennessee mountains.
Historically, Tennessee's most important mining products have been iron, bituminous coal, copper, lead, zinc, and phosphate. Iron ore was the most significant during early settlement years. Interest in the iron ore of the Western Highland Rim dates back to the 1790s and even earlier in the eastern mountains. The commercially valuable iron ores were located in the valleys and mountains of East Tennessee and in Middle Tennessee and were processed in facilities that supplied mostly local and regional markets.
By 1860 the state ranked third nationally in iron bloomery production, with Western Highland Rim properties in Stewart, Houston, Hickman, Montgomery, and Lewis Counties being particularly important. Early national census reports did not separate iron ore mining from iron production, but most early manufactories were associated with mines.By 1840 the U.S. Census reported iron production from eighty-two furnaces, bloomeries, forges, and rolling mills in East Tennessee; forty-seven in Middle Tennessee; and four in West Tennessee. In 1870, however, the census reported only six producers of iron ore in the state producing just over 34,600 tons of ore
By 1840 the U.S. Census reported iron production from eighty-two furnaces, bloomeries, forges, and rolling mills in East Tennessee; forty-seven in Middle Tennessee; and four in West Tennessee. In 1870, however, the census reported only six producers of iron ore in the state producing just over 34,600 tons of ore By 1910 the state reported forty-six producing iron mines. Pit mining along surface outcrops had almost disappeared, largely replaced by underground mining in the Euchee, Rockwood-Cardiff, and Chamberlain areas of central East Tennessee and the La Follette area of northeast Tennessee. In the early twentieth century iron mining became less and less important in Tennessee as the number of producing mines and the volume of ore production both dropped by roughly half from 1909 to 1919.
Iron's close companion in early industry was coal. Tennesseans began to mine coal in small quantities during the 1840s. Blacksmiths who used the coal in their shops undertook much of this activity. Unlike iron, however, coal production in the state has remained significant ever since. Tennessee coal is of the bituminous, or soft, variety and is found in extensive deposits along a northeast-southwest belt a little east of the center of the state.
Sub-terranian pressure fluctuations in caverns may also produce a similar effect - maybe without even registering on the rictor scale.?
