bounded rift zone which is responsible for the relatively high level of modern seismic activity in the New Despite these studies, the seismic activity in Kentucky remains relatively low in comparison to other areas of the United States, and there is no evidence that highly destructive seismic activity is likely in the near future. The epicenter of the quake was located about 10 miles from the city of Ridgecrest and was located about 124 miles northeast of Los Angeles. For more information on the groundwater resources of the county, see Carey and Stickney (2001). These Prior site planning that takes geology into account is always preferable to dealing with problems after a structure is built. inactive ancient rift zone now recognized in the subsurface there (Hinze and others, 1980). Lying in the central area of the North American Plate, the seismic zone is about 45 miles (70 km) wide and about 125 miles (200 km) long. Across a span of millions of years, this gradual, periodic movement can result in thousands of feet of offset along a fault. Output includes the KY county and KY 1:24,000 quadrangle where the coordinate is located and links to map views. the Illinois basin in Kentucky and forms the northern boundary of the east-west-trending Moorman The last time the VSZ caused so much chaos was in 1867 when it released an earthquake of 5.6-magnitude the strongest in Virginias history. fluorspar district (fig. New Madrid Seismic Zone (NMSZ), region of poorly understood, deep-seated faults in Earth's crust that zigzag southwest-northeast through Arkansas, Missouri, Tennessee, and Kentucky, U.S. Geophysical studies by Soderberg and Carroll County - Carrollton. It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg. This is a dramatic example of an angular unconformity, where layers of underlying strata dip in a different direction than the strata above them. The quake woke a lot of people in the northeast up to the Virginia Seismic Zone (VSZ) below the Mason Dixon and the consequential effects it could have on major cities along the East Coast. Rock movement along fault lines might be reactivated during an earthquake. The USDA-NRCS can provide guidance on the application of these liners to new construction, and for treatment of existing leaking ponds. Butler County - Morgantown. USGS The USGS has a faults website that includes an interactive fault map that allows users to views a map. *0 ! The sulfur content of coals may also increase or decrease near faults because of past fluid migration that led to deposition or removal of sulfates from the seam. Click the section headings to expand or collapse reports. gneiss, two-feldspar granite, medium-grade metamorphic rock, and anorthosite, while west of the front 0 earthquake. Welcome to the Kentucky Geography Network. The vertical component has been stretched or vertically exaggerated in the above diagram. 4 magnitude quake that occurred near the same location on July 4, 2019. Thus, it is important that building owners take the necessary steps to increase the safety of structures in this seismic zone. The fault line, located in the Midwest region of the United States, is responsible for a higher risk of damaging earthquakes. The Appalachian basin in Kentucky contains several major structural features: the Kentucky River and The quake was felt for over 200,000 square miles, including in the Carolinas, Alabama, Kentucky, and West Virginia. Carlisle County - Bardwell. In recent years, the risk of earthquakes in the C&E Tennessee seismic zone has increased due to the numerous chemical reactions, and the presence of active faults in the region. Dataset Size: 0 bytes. Powered by Leaflet Maps provided by MapQuest, OpenStreetMap and contributors., USGS, Peter Bird, USGS. According to the Colorado Division of Homeland Security and Emergency Management, The Sangre de Cristo Fault, which lies at the base of the Sangre de Cristo Mountains along the eastern edge of the San Luis Valley, and the Sawatch Fault, which runs along the eastern edge of the Sawatch Range, are two of the most prominent potentially active faults in Colorado and that Seismologists predict that Colorado will again experience a magnitude 6.5 earthquake at some unknown point in the future.. Faults represent breaks in the Earth's crust. Updates? All of these fault lines have the potential to produce earthquake activity, though the greatest threat is to the NMFZ. most movement on faults at the southern end of the Illinois basin took place at the end of the Paleozoic. Silurian deformational event argues against an impact origin. 0 earthquakes recorded in history. Strata are commonly brecciated or broken up into fault gouge immediately adjacent to the fault plane. Please refer to the appropriate style manual or other sources if you have any questions. Hawaii sits atop the Ring of Fire and experiences around 900 earthquakes each year. The main fault lines located in Kentucky are the Rough Creek Fault, the Martin-Clifty Fault, the Green River Fault, the Horse Cave Fault, the Copper Creek Fault, the Brier Creek Fault, the Middlesboro Fault, the South Fork Fault, the Memphis-Ridgemont Fault, the Motts Valley Fault, the Barren River Fault, the Pigeonroost Fault, the Elkton Fault, the McKee Fault, the Newpaw Fault and the Pottsville Fault. fields indicate dip-slip movement (Palmer, 1969). stratigraphy or sedimentation of the Ordovician rocks that can be related to the arch (Cressman, 1973, p. 8; The fault passes through Winston, Blount, Cullman, and Marshall counties, as well as portions of Madison, Jackson and Dekalb counties, before continuing into northern Mississippi. The Appalachian basin is divided structurally into an eastern highly deformed part, the fold-and-thrust The 9. Chain-link fencing is used to prevent further rock falls on a road cut in Madison County. The. Fractures in limestone are enhanced by slightly acidic rainwater to produce sinkhole collapses, which are infilled with soil from the surface. Major tectonic events in Kentucky for which evidence has accumulated begin with late Precambrian rifting There, the Devonian (red on the section) and Mississippian (light blue on the section) strata appear to split upward on the eastern (right) side of the diagram. Most polygon layers have some transparency set (e.g. Remedies vary from mere maintenance that keeps drainage away from the house to expensive reconstruction of foundations. The origin of the Muldraugh dome is uncertain. Within the thin Kentucky River valley along the northern edge of Madison County, and in the lower reaches of the valleys of the larger creeks that empty into the Kentucky River, most drilled wells will produce enough water for a domestic supply at depths of less than 100 feet. document.write(d.getFullYear()); In addition, Keller and others (1982) The Mississippi Embayment is currently delineated by the Cretaceous and Tertiary coastal plain strata (see of the Cumberland Plateau and is represented at the surface mainly by strata of Pennsylvanian age. The Versailles structure is about 10 mi west of This new map shows yellow, orange and red lines, which denote differing likelihoods of an earthquake along each fault. Weir and others, 1984), though Borella and Osborne (1978) suggested that the area of the Jessamine dome Topographical changes resulting from the earthquakes included fissures, landslides, subsidence (sinking) and upheavals, soil liquefaction, the creation and destruction of lakes and swamps, and the wasting of forests. now = new Date; Parts of Kentucky may be profoundly affected by seismicity in the well-known New Madrid seismic zone of 9) coal (Greb and Williams, 2000). recurrence curve plotted for the New Madrid seismic zone (Nuttli, 1979) shows that, for example, in a These faults were pathways for mineral-rich fluids, which deposited many types of minerals including fluorite. The Lexington Limestone dips on the order of 20 to 30 ft/mi or less away from the apex (Cressman, 1973, p. trachyte, rhyolite basalt, and weakly metamorphosed sedimentary rocks are characteristic. Purchase and extends southwestward into Missouri, Arkansas, and Tennessee, suggest that it is a fault [Click on image to see a larger version in a new window. Pennsylvanian unconformity. Contains faults, geologic units, and geologic contacts. The Waverly arch and the Kentucky strata. NEXT||PREVIOUS||TABLE OF CONTENTS. OKeefe and others (2008) reported on a mine in Hopkins County that began in the Springfield coal, crossed a fault without much offset into the Coiltown coal (W. Ky. No. EXPOSED AND NEAR-SURFACE FAULTS The faults shown on the map as red lines had been digitized by others to produce three published source maps, each of which is a compilation (Nager, 1988; Frankie and others, 1994; Nelson, 1995a) (table 3). Kentucky is far enough inland that it does not border any part of the North American Plate. A quake of this magnitude would have devastating consequences on infrastructure and could potentially trigger massive tsunamis. Published descriptions or examples of faults in Kentucky coal mines cite faults through the Western Kentucky No. if (thisYr < 1900) { Some wells in this area drilled along drainage lines that may produce enough water for a domestic supply except during dry weather. . Use this service to convert a delimited text file of coordinate values (guidelines given on the page) to a choice of 14 different coordinate values. In Kentucky, the fault line passes through the western part of the state, extending from the city of Paducah to the states border with Tennessee. Of the three From AIPG (1993). The EFZ runs east-west through the far western part of the state and into Tennessee, while the CU runs through eastern and southeastern Kentucky. Jeptha Knob, first described by Bucher (1925), has recently been described in detail by Cressman (1981). Therefore, the term "Illinois basin" is used herein to avoid confusion.) 15). 16). Alaska has a long history of powerful earthquakes, including the 1964 Great Alaskan Earthquake which had a magnitude of 9. While every effort has been made to follow citation style rules, there may be some discrepancies. 1979, p.
