Mapped faults provide an obvious location and orientation that can be projected in advance of mining. In addition to the physical destruction caused by the 9. 0000000476 00000 n and Pakiser, 1982) provides detailed descriptions of historic and modern seismicity and geologic and The first shock was felt from Canada to New Orleans and as far away as Boston, Massachusetts and Washington, D.C. http://kgs.uky.edu/kgsweb/download/wrs/MADISON.pdf, Water well information is available at: http://wris.state.ky.us/website/kgs/viewer.htm. The pressures from mountain building caused the northeast edge of a block of Devonian, Mississippian, and Pennsylvanian strata to be pushed upward, forming a 125-mile long ridge that we call Pine Mountain. 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. Arkansas experiences earthquakes due to having proximity to the New Madrid Fault Line. Cressman (1981) suggested that Mississippian doming over a pre We are currently working on a solution for this issue. A recent seismic study of the crustal expression of a cryptoexplosive structure nearly 4 mi across in Lower and Middle Pennsylvanian rocks. 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). The arch thus separates the Appalachian basin A variety of datasets can be located and downloaded, static map products can be viewed, and many web mapping applications and services are easily accessible. (photo by Edward Nuhfer), Homes constructed in areas of steep slopes can cause earth movements if not properly planned, as shown in the photographs above and below. bounded rift zone which is responsible for the relatively high level of modern seismic activity in the New Campbell County - Alexandria. Silurian deformational event argues against an impact origin. northeastern Kentucky (Dever and others, 1977). This is called a fault. Planning and mitigation: Geologic maps of the mined area should be examined prior to mining to see if any surface or subsurface faults occur in the mined area. characterized at the surface by concentric and radial faults, an uplifted, brecciated, and partly dolomitized An Equal Opportunity University. The New Madrid earthquakes of the winter of 1811-1812 were the largest in the history of the United States. Six states that are most at risk for earthquakes are Alaska, California, Hawaii, Washington, Oklahoma, and Arkansas. to be a positive feature in Devonian time, but its influence on sedimentation in Kentucky waned and Thanks for contacting us. document.write(thisYr); Dataset Size: 0 bytes. What is the Jane Austen Society of North America. Soderberg and Keller (1981) suggest that it is underlain by a deep-seated graben of late Precambrian age, Washington experiences frequent, moderate earthquakes from its many active fault systems. Irvine-Paint Creek fault systems, the Pine Mountain thrust fault, and the Waverly arch of northeastern the Nashville dome in central Tennessee through central Kentucky to northwestern Ohio, where it Specifically, the region of Kentucky is in the Central and Eastern Tennessee Seismic Zone, which is classified as a high hazard by the United States Geological Survey. The Grenville Front, apparently in Definition and formation: Faults are breaks in the earths crust across which movement has occurred. and Kankakee arches on the north and east (fig. For example, recent studies have suggested that deep-injection wells and hydraulic fracturing may cause minor earthquakes. New Madrid Seismic Zone (NMSZ), region of poorly understood, deep-seated faults in Earths crust that zigzag southwest-northeast through Arkansas, Missouri, Tennessee, and Kentucky, U.S. But while Americans are aware of the San Andreas fault and the seismic activity in California, which has wreaked havoc in San Francisco and Los Angeles, there are other, lesser-known fault lines in the United States that fly dangerously under the radar. The fault shown cutting the Cincinnati Arch in the block diagram is part of the Lexington Fault Zone. The current form of the embayment in Kentucky was established in latest 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. Slickensides are common and tend to parallel the direction of movement along the fault. ), Swelling soils and expansive clay shales can cause construction problems in some areas of the county. zones and some associated with dolomitization (Black and Haney, 1975). A quake of this magnitude would have devastating consequences on infrastructure and could potentially trigger massive tsunamis. The Appalachian basin in Kentucky contains several major structural features: the Kentucky River and Irvine-Paint Creek fault systems, the Pine Mountain thrust fault, and the Waverly arch of northeastern Kentucky (fig.16). The GFZ runs north-south through central Kentucky, stretching from near Louisville eastward to the Appalachian foothills. Jeptha Knob, first described by Bucher (1925), has recently been described in detail by Cressman (1981). now = new Date; The last one was in 1884. # / ) ) 0 $! Across a span of millions of years, this gradual, periodic movement can result in thousands of feet of offset along a fault. basin as a whole contains sedimentary rocks of Precambrian to Early Permian age in a sequence that has a Appropriate preparation is needed when approaching faults underground, in case fluids or gases are encountered. by the Kentucky Geological Survey, University of Kentucky. The basin In the end, some 3,000 to 5,000 square miles (7,800 to 13,000 square km) were visibly scarred with the effects. In the block diagram, one can see that the faults continue beneath the Tertiary strata. The ground shaking that would result could cause buildings to collapse, gas pipelines to rupture, and transportation routes to be blocked. Rough Creek fault system through at least Early Permian time. Ervin and McGinnis (1975) suggested, largely on the American Institute of Professional Geologists, 1993, The citizens' guide to geologic hazards: 134 p. Black, D.F., 1989, Tectonic evolution in central and eastern Kentucky; a multidisciplinary study of surface and subsurface structure,U.S. Many surface-fault traces are mapped on 7.5-minute geologic quadrangle maps for Kentucky, and can be viewed online on the digital geologic map information service. if (thisYr < 1900) { There has been no activity along these faults in recorded history. What are gas prices at Buc EEs in Richmond KY? 14), and then after some distance, crossed another fault. Cincinnati arch.--The Cincinnati arch, a prominent regional uplift in the eastern midcontinent, extends from From AIPG (1993). fields indicate dip-slip movement (Palmer, 1969). Through millions of years, strata have gradually dropped downward above the rift, along the southern edge of the Rough Creek faults and the northern edge of the Pennyroyal Faults. Kentucky is one of the top ten limestone producers in the country. The general configuration of the basin is shown by a contour map of the base of the Rock strata often dip more steeply near faults or between closely spaced faults. This print tool currently honors the default opacity/transparency of each layer (if you change the opacity of a layer, the updated rendering will NOT be printed). A few drill holes have penetrated these rocks in central Kentucky where they are as little as 5,000 feet beneath the surface, but in most areas they occur at depths that have not been drilled, so little is known about them. County geology. Pennsylvanian unconformity. However, there is some debate over whether or not there has actually been a 10. The most powerful earthquake to be ever recorded was a 9. Other leakage prevention measures include synthetic liners, bentonite, and asphaltic emulsions. Which 6 states are most at risk for these earthquakes? Drag folding and steepened bed dips (with possible bedding-plane movement along beds) near faults can also lead to roof weakness. These fault systems were formed along the edges of a broad rift or crack in the Earth's crust that occurs deep beneath the surface, and extends from western Kentucky to the Mississippi River. Powered by Leaflet Maps provided by MapQuest, OpenStreetMap and contributors., USGS, Peter Bird, USGS. 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 feature is about 5,000 ft in diameter and is in limestones and shales of In some cases, coals become mineralized (calcite veins, etc.) by the Kentucky Geological Survey, 16). (The Illinois basin is referred to in some reports, for These fault lines are all part of the larger New Madrid Seismic Zone, a region spanning 7 states and known for its earthquake activity. Faults may be associated with increased fracturing of bedrock in the immediately adjacent area. suggest that the Waverly arch represents the position of this migratory arch during Beekmantown (Early Denison and others (1984), in a report on basement rock types and age in syncline (fig. Kentucky (Nuttli, 1979, p. 68). The arch continued Natural gas piplines (30-inch mains) are laid across a new subdivision in Kingston, Madison County. It has produced magnitude 8 to 8. A recently assembled series of studies on the New Madrid region (McKeown border of the trough, which coincides with the Kentucky River fault system. } The fractures are covered by thick layers of rock, which in turn are . We obtained all three digitized sets of fault locations. Still, this quake caused significant damage to homes and infrastructure in the area, with an estimated $3 million worth of damages. Usually, movements along faults are not great at any one time.

(photo by Edward Nuhfer). There are no active plate tectonic movements in this area at the present time, and as such, there are no active fault lines. Contact the Webmaster for questions and comments. Geophysical studies by Soderberg and Where this occurs, minor unmapped faults may be encountered. Harris (1978) combined the Rome trough with Of the three Kentucky geologic map data A GIS database of geologic units and structural features in Kentucky, with lithology, age, data structure, and format written and arranged just like the other states. thisYr = thisYr + 1900; 11) and continue mining. Turn off the KY basemaps layers to display these ESRI basemaps. Branches of the fault extend into Arkansas, Missouri, Tennessee, and Kentucky. extensive denudation. xref It was the first major seismic activity in Ky since 2003 when a magnitude 4. 1 magnitude earthquake occurred in the state of California on July 5, 2019. This is a known . For example, in 1980 New Madrid experienced a magnitude 5. This structure is not 133 0 obj <> endobj Whaley and others (1980), in a description of the structures These cracks in the crust have caused considerable damage in the past and scientists say will do so again. These structures are described by the following categories: The block diagram shown above, represents a slice through Kentucky, as if a giant knife had cut the State to a depth of 3,000 feet. Ordovician inception of the arch in Kentucky, the geologic quadrangle mapping has shown no features of Use this service to convert a single coordinate value (lat/lon, KY single zone, carter coordinate, etc..) to 14 different coordinate values. dome (Lexington dome of some authors), a culmination of the arch in central Kentucky; the Cumberland USGS Interactive Fault Maps. A map of global tectonic and volcanic activity over the last one million years, showing: active ridges, continental extensions, transform faults, ridge spreading rates and directions, continental rifts, subduction and overthrust zones, and generalized volcanic activity. 0 The debate over the maximum magnitudes of earthquakes is still ongoing and there has yet to be a definitive answer as the exact measurement of magnitude is hard to pin down due to the strength of the tectonic plates in different areas. 16). Getting the basin filled with water as soon as possible after construction prevents drying and cracking, and possible leakage, of the clayey soil liner. 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. response to some later event, formed along the western margin of the gravity high (Lidiak and Zeitz, 1976; There are numerous faults in Kentucky. hb```">&S ac`a8 _o9j{VkL*1{|icPGEO&u\w:=q$O\S-9 T ` ` @@ vfb3"|$2f b v` rY lY`a609060 `@X vH;3b :k0\U\(C&0@u0 FV\s 3) were developed from a complicated process that started with a group of engineers, seismologists, and others using the national seismic hazard maps developed by the U.S. Geological Survey and engineering science. The quake occurred at 8:59 am local time and was felt from Jackson to the west, into Indiana and further east to Berea. place of about 35,000 ft (Colton, 1970, p. 13). most movement on faults at the southern end of the Illinois basin took place at the end of the Paleozoic. lineament, defined by aeromagnetic and gravity data, which lies across the easternmost tip of Kentucky; The potential for significant shaking and ground movement can cause considerable damage to structures in the region. FIGURE 16.--. eastern Kentucky northeastward across West Virginia into Pennsylvania. Located in far Western Kentucky is one of our most popular outdoor areas: Land Between The Lakes (LBL). Rough Creek graben, that was active as early as latest Precambrian or earliest Cambrian time and that has One of the largest earthquakes in North American history happened just west of Hickman, Kentucky, on the Missouri side of the Mississippi River. The. Engineering design principles are employed in roadways and bridges to prepare for such situations. The 9. The relatively high seismicity is probably due to resurgent tectonics in the angle normal faults and less common reverse faults bounding a series of grabens and horsts, with a total 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. The most dramatic fault shown in the block diagram is the Pine Mountain thrust fault, which occurs in southeasternmost Kentucky. Below the sedimentary rocks are igneous and metamorphic rocks. gravity high, which passes north-south through east-central Kentucky. Map of active US fault lines in the USA by USGS. The quake was felt across much of the state and many neighboring states. Therefore, the term "Illinois basin" is used herein to avoid confusion.) Major structural elements within the basin in Kentucky are the Rough This fracturing may influence slope stability and groundwater flow in these limited areas. Thus, it is still unknown whether or not there has ever been a 10. However, there have been seismic readings taken from areas like the Indian Ocean that have recorded seismic readings of up to 10. bifurcates to form the Kankakee and Findlay arches (fig. Major tectonic events in Kentucky for which evidence has accumulated begin with late Precambrian rifting 38) reported wells penetrating brecciated Knox dolomites and cherts below coherent Silurian dolomite, 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. considerably more data, report a close correlation between gravity anomalies and basement lithology: Creek and Pennyrile fault systems, the Moorman syncline, and faults in and around the Illinois-Kentucky %PDF-1.4 % All files associated with this page are copyrighted 1997 beyond the surface faults shown on the map (sheets 2 and 3), as a concealed system that extends into West 15). This rock is used for making aggregate, agricultural limestone and for cement and asphalt production. trailer Carter County - Grayson. Early Silurian time (McDowell and Peterson, 1980; McDowell, 1983), when strata of the eastern flank began Embayment across a gentle, northwest-trending arch (Heyl and others, 1965; Pinckney, 1976; Trace and However, Ammerman and Keller This 150 mile-long series of faults stretches under five states: Illinois, Missouri, Arkansas, Tennessee and Kentucky, and is responsible for four of the largest earthquakes in the history of. Middle and Late Ordovician age; no younger beds are preserved in the area. thrust that underlies the structurally complex Middlesboro syncline. Updates? University of Kentucky. strata. KGS Home > Geology of Kentucky Earthquakes in Kentucky mostly occur due to seismic activity associated with the New Madrid and Wabash Valley Seismic Zones, though there can be earthquakes caused by other seismic events. This devastating earthquake destroyed numerous homes and took the lives of over 2,000 people. Roof support: Slickensides and fractures near faults can cause adverse roof conditions, and roofs may require supplemental support, as discussed for fractures. the presence of an ancestral Mississippi Embayment. The quakes epicenter was in Mineral, Virginia, about 90 miles southwest of Washington, D.C., and was so powerful that Union Station, the Pentagon and the Capitol Building were all evacuated. 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. Keller and others, 1982, p. 220). 1 on the Richter scale. basis of geophysical data, that the present embayment stems from the late Mesozoic reactivation of the The vertical component has been stretched or vertically exaggerated in the above diagram. Lexington (sheet 2 of the geologic map), near the axis of the Cincinnati arch (fig. The US Geological Survey estimates that the likelihood of an earthquake with a magnitude of 6 or greater in Kentucky is 0. In 2011, New Yorkers were jolted by a5.8 magnitude earthquake that shook the East Coast from New Hampshire all the way down through Chapel Hill, North Carolina. parts of Illinois, Indiana, and Kentucky and lying between the Ozark uplift on the west and the Cincinnati Most polygon layers have some transparency set (e.g. The quake was felt widely throughout the state and even as far away as Las Vegas, Nevada. East and west of the axis of the Arch, strata gradually dip beneath the surface into two bowls or depressions in the Earth's crust, called basins. Exploration for oil and gas in Kentucky has resulted in considerable information on the nature of the How likely is Kentucky to have an earthquake? and especially in western Kentucky. That is because the strata on the left side of the photo have moved downward relative to the strata on the right side of the photo. Yes, Ky has had a major earthquake in the past. downward as much as 200 ft. Fractured limestone, such as that found in Richmond, can result in leaky reservoirs or embankments. This map courtesy of the U.S. Geological Survey (USGS) shows the major earthquake hazard areas within the United States based on fault lines. or post-Paleozoic movement. 0000000879 00000 n And there are many more than what you would expect! Popular Kentucky Earth Science Publications. Oil, natural gas, and water can migrate along faults, leading to oil-, gas-, and water-charged sandstones in mine roofs near faults. Kentucky is far enough inland that it does not border any part of the North American Plate. Thousands of milder aftershocks occurred daily for more than a year. Rock excavation may be required in areas with shallow soil (excavation was not required here). Virginia (Dever and others, 1977). Cross sections and block diagrams (like the one above) can be used to illustrate why the units of geologic strata on the geologic map and corresponding land-surface features on the physiographic map occur where they do in the State. Cable and Beardsley (1984) have traced the westward This 150 mile-long series of faults stretches under five states: Illinois, Missouri, Arkansas, Tennessee and Kentucky, and is responsible for four of the largest earthquakes in the history of the United States, which took place over three months from December 1811 and February 1812. marking a region of continental collision associated with the Grenville event. No, Pine Mountain in Kentucky is not a fault line. This function will create two bookmark links to save the current map layout with or without the current extent: These basemaps are displayed above the ESRI basemaps. (1982) points out that the New Madrid earthquakes were characterized by a particularly large "felt area" and Illinois basin.--The Illinois basin is a major structural downwarp in the eastern midcontinent, occupying large The closest tectonic plate to Kentucky is the North American Plate, which runs along the east coast of the United States and covers most of North and Central America. Engineering design principles are employed in roadways and bridges to prepare for such situations. Harris (1970) has shown the fault to be a ramp on a bedding plane It started at 8:11pm GMT on May 22nd 1960 and ended at approximately 8:21pm GMT. of the Cumberland Plateau and is represented at the surface mainly by strata of Pennsylvanian age. 0000000016 00000 n Mitchell County Earthquake - July 8, 1926. 15). *0 ! Although some reports indicate an Early Fractures in limestone are enhanced by slightly acidic rainwater to produce sinkhole collapses, which are infilled with soil from the surface. 8). It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg. The Reservoir embankments built on limestone must take into account the type of rock used as a base. The broad, East of the fluorspar faults there are two sets of faults that trend east-west. The zone of radiating faults in far western Kentucky adjacent to the Tertiary strata are part of the Fluorspar District. 19 earthquakes in the past 30 days. The Waverly arch and the Kentucky Thus, it is important that building owners take the necessary steps to increase the safety of structures in this seismic zone. southern part of the Illinois basin lies in Kentucky and includes the Pennsylvanian strata of the western coal No major damage was reported, although numerous cracks and water leaks appeared in homes in Hardinsburg. NEXT||PREVIOUS||TABLE OF CONTENTS. The hard dolomite of the Boyle formation was undercut by weathering of the softer shale of the Crab Orchard Formation, which caused the dolomite to fracture and fall. This was followed by Middle(?) Kentucky. 4 magnitude quake that occurred near the same location on July 4, 2019. Don't search a large area this way, it takes too long. Beneath the Surface [Geologic Structures]. Nelson (1981, 1983) provided examples of mining adjacent to and through faults in southern Illinois. There are at least 16 known fault lines in Kentucky, with many more that have yet to be mapped and studied. Normal faults are faults in which one side of the earths crust is offset downward relative to the other side. A detail of the western part of the block diagram, presented as a cross section (2-dimensional panel illustration) how the Tertiary and Cretaceous strata cut across the older Paleozoic strata, and dip into the Paducah-Memphis Basin. 9) coal (Greb and Williams, 2000). 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. The faults that cut across the coal field are part of the Rough Creek FAult System. Principal structural features of the arch in Kentucky are the Jessamine Contact the Kentucky Division of Water, 14 Reilly Road, Frankfort, KY 40601, telephone: 502-564-3410. The Irvine-Paint Creek fault system extends eastward from central Resource maps of most of the mined coal beds in western Kentucky show that a large number of mines are bounded by faults. Geological Survey OF-89-0106, Plate 11, 151 p. Carey, D.I., and Stickney, J.F., 2001, Ground-water resources of Madison County, Kentucky: Kentucky Geological Survey, Open-file Report OF-01-73, 30 p. Blue Grass Area Development District, 2003. Fault gouge formed from movement along the fault. in western Kentucky (the Rough Creek graben of Soderberg and Keller (1981) and the Mississippi Offset along faults may be measured in inches to thousands of feet. In most cases, faulting impedes mining and forms the boundary of a mine, so adverse roof conditions adjacent to faults lead to entries along mine boundaries being abandoned. Throughout the county ground water is hard or very hard and may contain salt or hydrogen sulfide, especially at depths greater than 100 feet. Atherton (1971, p. 37) suggested that the Kankakee arch, the northwestward extension of the may have originated much earlier, however: Schwalb (1969, p. 9) identified a Cambrian-Ordovician basin of show the general aspect of this broad uplift and the high-angle fault systems that transect it. Geologists in Kentucky keep a careful eye on the New Madrid area, in hopes that they can develop methods for predicting future quakes. Carlisle County - Bardwell. This area, mostly on sheet 3 of the geologic map, forms a part We've received your submission. granites, metasediments, and felsic volcanics are associated with gravity lows, while mafic volcanics, 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. Map showing Quaternary faults in the western U.S. and Pacific Ocean. The fact is most states are at risk of major . These Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. concurrent with this early period of arching has been demonstrated by Simmons (1966). Black (1978) has compiled structure contours for central Kentucky from the geologic quadrangle maps. Thankfully, there were only minor reported injuries and no deaths associated with the quake.
