This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop crust and mantle models of the Eastern Tennessee Seismic Zone (ETSZ) using imaging and inversion of the radial component P-wave transfer functions for stations in the Center for Earthquake Research and Information's (CERI) eastern Tennessee seismic network. We find complex structure in the upper 10 km in addition to an upper mantle high velocity zone with Vp values from 8̃.2-8.56 km/s. This high velocity zone most likely extends from the west into the ETSZ and may be preserved mantle structure from the Granite Rhyolite province. Moho in the area is mostly gradational. However, velocity discontinuities can be seen at places indicating a fairly stable Moho depth of 4̃5-50 km. We suggest that the NY-AL lineament represents a major deep crustal to upper mantle feature.

Available in PDF, EPUB and Kindle. Book excerpt: Part 1: A phased array of 19 broadband seismometers was deployed from November 2009 to September 2011 to detect nonvolcanic tremor associated with the Reelfoot fault. An autodetection algorithm using broadband frequency & ndash;wavenumber analysis was used to search for the recurrence of signals. The original signals, detected in 2006, appeared as short duration, impulsive arrivals with a high phase velocity. We identify thousands of signals during the experiment. Two azimuthal peaks are observed arriving from the west and northeast. The detections are similar to the events seen in 2006 and are inferred to come from very small ML=-1 microearthquakes occurring in shallow basement faults. Most signals arrive with coherent S-wave energy which implies very small local and regional earthquakes. Other signals show distinct changes in slowness and azimuth as a function of time. These events were interpreted as atmospheric acoustic sources. The high-frequency content and impulsive arrivals of the nonacoustic arrivals are not consistent with traditional tectonic tremor but indicate seismic activity in the crust near the Reelfoot thrust fault. Part 2: Waveforms from the Eastern Tennessee Seismic Network are corrected to the nominal Wood & ndash;Anderson (WA) torsion seismometer to obtain a total of 11,905 amplitudes to determine a local magnitude scale for the Eastern Tennessee Seismic Zone (ETSZ). We obtain the following distance correction function: -log10(A0)=0.538log10(r/17) & minus;0.0002516(r-17)+2.0 from our inversion. The -log10(A0) is very flat at distances> 200 & thinsp; & thinsp;km, suggesting low distance attenuation at local and near-regional distances. The b-values for the currently reported duration magnitude is 0.9. Part 3: Dispersion measurements obtained from ambient noise tomography and earthquake data are combined with radial receiver functions from 134 stations to invert for a high resolution shear-wave velocity model of the ETSZ. We obtain velocities models to depths of 200 km to obtain information about the structure of the crust and upper mantle. We detect a strong velocity contrast across the vertical projection of the New York & ndash;Alabama lineament which we attribute to an ancient strike-slip fault. We also observe a low-velocity zone in the upper mantle which could be the base of the continental lithosphere in this area. The majority of the depths of this low velocity zone begin around 125 km.

This book was released on 2012 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume focuses on the continental intraplate region of the United States and provides an update and overview of documented Quaternary faulting and paleoseismic liquefaction east of the Rocky Mountains, and of the application of these results to seismic hazard and risk assessments. Contributions include papers that describe zones of newly recognized Quaternary deformation such as the East Tennessee Seismic Zone, as well as reinterpretations of well-known areas such as the New Madrid Seismic Zone. The chapters make important contributions to the recognition of earthquake sources active during the Quaternary and assess the seismic hazards posed by these sources. This volume should interest a wide range of readers from geology, seismology, hazard assessment, and emergency management"--Provided by publisher.

Download or read book A New Set of Focal Mechanisms and a Geodynamic Model for the Eastern Tennessee Seismic Zone written by Matthew T. Cooley and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new set of focal mechanisms is determined for the eastern Tennessee seismic zone (ETSZ). The 26 solutions are consistent with previous solutions in the northern and middle portions of the ETSZ and extend coverage into the southern portion. The solutions exhibit strike-slip and oblique normal faulting, with nodal planes generally oriented N-S/E-W and NE-SW/NW-SE. Strike-slip solutions dominate the middle and northern portions of the zone. To the south, near the Tennessee/Georgia border, a group of focal mechanisms for relatively shallow events exhibit normal faulting. To examine a possible cause of the normal faulting, a geodynamic model is developed which simulates a delamination of the lower crust. Evidence for delamination has been seen elsewhere in the southern Appalachians. Results from this model suggest that delamination is a possible cause of localized, shallow normal faulting.

Available in PDF, EPUB and Kindle. Book excerpt: Memphis is built on land once the bottom of a sea, Nashville rests within a 600-foot-depth basin eroded from a mighty arch, Knoxville and Chattanooga nestle on lands that have migrates - Knoxville's underpinning traveling all the way from the middle of Sevier County. Our Restless Earth is written for all Tennesseans who are curios about the origins of familiar landscapes. Edward T. Luther describes a state that has attracted specialists from all over the world to study its fascinating geology, a state that in its long east-west axis encompasses nine distinct geologic regions. Appearing here are phenomena such as the New Madrid earthquake that formed Reelfoot lake, the state's almost forgotten gold rush, 60-foot reptiles that once inhabited parts of McNairy County, and the contrary Tennessee River that could not decide which way to flow. The origins of the state's oil, coal, iron, marble, and famous cave country - these too are a part of Our Restless Earth. Edward T. Luther is a native Tennessean whose professional career as a geologist and personal interest in writing have pointed him toward the preparation of this book. Since receiving his advanced degree in geology from Vanderbilt University in 1951, he has come to know that state intimately - first as a team member of the Tennessee Geological Survey and more recently as supervisor of the Survey's research program. He is also an avid reader of fiction and has long been interested in applying writing skills to his technical knowledge in order to make the fascinating science of the earth available to a wider audience.
