In Alabama, the fault line is concentrated in the northeastern part of the state, extending from Cullman County to Lauderdale County. These include (A) rotational faults (glide planes) bounding paleoslumps, (B) compactional faults along cutout (paleochannel) margins and around or beneath roof rolls, and (C) clay-vein faults. startxref
This fracturing may influence slope stability and groundwater flow in these limited areas. No, there is no tectonic plate located in Kentucky. King and Zeitz (1978) have recognized the New York-Alabama basement While the majority of these earthquakes were of a low magnitude, some of them caused significant damage. This is called a fault. suggest that the Waverly arch represents the position of this migratory arch during Beekmantown (Early 3 earthquakes in the past 7 days. 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. It has produced magnitude 8 to 8. 0 earthquakes recorded in history. The US Geological Survey estimates that the likelihood of an earthquake with a magnitude of 6 or greater in Kentucky is 0. These are discussed in the section on faults.

Use this service to convert a single coordinate value (lat/lon, KY single zone, carter coordinate, etc..) to 14 different coordinate values. 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. Bullitt County - Shepherdsville. 16). 14), and then after some distance, crossed another fault. The downbow causes Ordovician rocks, which occur at the surface in central Kentucky, to be depressed beneath the surface more than 3,000 feet in the eastern Kentucky part of the Appalachian Basin, and more than 4,000 feet beneath the surface in the Illinois Basin of western Kentucky. 16). Right: With time, expanding soils exert several tons per square foot of pressure on the foundation and shallow pilings. Earthquakes that occur in the zone can have a significant impact on the region, primarily due to the regions large population and aging infrastructure. Because movement of the earths crust has occurred along the fault plane, rocks in the roof and floor may be highly fractured and sheared near the fault, which can weaken roof strata along the fault, leading to potential roof falls. Kentucky (fig. The most powerful earthquake to be ever recorded was a 9. Let us know if you have suggestions to improve this article (requires login). Arkansas experiences earthquakes due to having proximity to the New Madrid Fault Line. Contains faults, geologic units, and geologic contacts. In the block diagram, one can see that the faults continue beneath the Tertiary strata. digital geologic map information service, 310 Columbia Ave, 228 Mining and Mineral Resources Building, University of Kentucky, Lexington, KY 40506-0107. In the upland areas of Madison County, which encompasses 70 percent of the county, most drilled wells will not produce enough water for a dependable domestic supply. Other interesting features. Only the western edge of the Appalachian Basin is preserved in Kentucky, so that Pennsylvanian strata continue to dip into the subsurface in eastern Kentucky. granites, metasediments, and felsic volcanics are associated with gravity lows, while mafic volcanics, The feature is about 5,000 ft in diameter and is in limestones and shales of No, Pine Mountain in Kentucky is not a fault line. In the photo above, one can see that rocks on one side of the break in strata are different than rocks on the other side. (The Illinois basin is referred to in some reports, for The basin 5 earthquake, the resulting tsunami impacted countries thousands of miles away, devastating communities and taking even more lives. thisYr = now.getYear();

Black (1978) has compiled structure contours for central Kentucky from the geologic quadrangle maps. Getting the basin filled with water as soon as possible after construction prevents drying and cracking, and possible leakage, of the clayey soil liner. composite thickness for the entire basin of at least 63,000 ft but reaches a maximum thickness in any one by a brecciated center within a belt of concentric faults. 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 New Madrid, Reelfoot, and Wabash Valley seismic zones sometimes affect the state, but they are located in adjacent Missouri and Tennessee. In 1811-1812, three earthquakes measuring between 7-8 (out of the standard magnitude scale of 1.0-10.0) in magnitude originated from this fault. 70 mi on the Grenville Front at the Kentucky River fault system and a north-trending basaltic rift zone some This was followed by Middle(?) southern part of the Illinois basin lies in Kentucky and includes the Pennsylvanian strata of the western coal Throughout the county ground water is hard or very hard and may contain salt or hydrogen sulfide, especially at depths greater than 100 feet. Kentucky, United States has had: (M1.5 or greater) 0 earthquakes in the past 24 hours. 38) reported wells penetrating brecciated Knox dolomites and cherts below coherent Silurian dolomite, Noger, M.C., compiler, 1988, Geologic map of Kentucky: sesquicenntennial edition of the Kentucky Geological Survey: U.S. Geological Survey and the Kentucky Geological Survey, scale 1:500,000. 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. Data set is derived from the 7.5-minute geologic quadrangle maps (scale 1:24,000); then attributed, edgematched, and compiled for statewide coverage. 0
Alaska has a long history of powerful earthquakes, including the 1964 Great Alaskan Earthquake which had a magnitude of 9. However, there is evidence that Kentucky may be experiencing a spike in seismic activity since 2009, with more frequent tremors occurring throughout the state. Principal structural features of the arch in Kentucky are the Jessamine The largest earthquake in recorded history to have ever occurred in Kentucky was a magnitude 5. initiation of the Illinois and Appalachian basins. (Photo by Paul Howell). document.write(d.getFullYear());
Reservoir embankments built on limestone must take into account the type of rock used as a base. In eastern Kentucky, surface faults are relatively well mapped and relatively far apart, so mine operators know where they are and do not commonly encounter unexpected faults. The epicenter was in the vicinity of New Madrid, The Mississippi Embayment is currently delineated by the Cretaceous and Tertiary coastal plain strata (see Trends: Faults tend to have linear to slightly curving trends, so orientations can be projected in advance of mining. }
Lexington, Kentucky River, and Irvine-Paint Creek fault systems (fig. Usually, movements along faults are not great at any one time. Rough Creek fault system through at least Early Permian time. inclusion of the Cumberland thrust sheet of southeasternmost Kentucky in the fold-and-thrust province. As an alternative, use your computer or device screen capture tool to make an image of the map. A recently assembled series of studies on the New Madrid region (McKeown Most of this data has been summarized by McGuire and Ordovician) deposition. Geophysical studies by Soderberg and 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. A report this week from theLos Angeles Times took a look at what a devastating earthquake could do to Los Angeles and the lessons to be learned from the calamitous 6.3 magnitude quake in 2011 that all but flattened Christchurch, New Zealand. The Kentucky Building and Residential Codes (Fig. 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. Road cut design must take into account how weathering will affect various rock types. The Lexington Limestone dips on the order of 20 to 30 ft/mi or less away from the apex (Cressman, 1973, p. The quake was felt for over 200,000 square miles, including in the Carolinas, Alabama, Kentucky, and West Virginia. (epicentre 36.6 N 89.6 W), each measuring greater than magnitude 7.0. Please refer to the appropriate style manual or other sources if you have any questions. Borden Formation (Mbf) at the east margin of sheet 3 about 4 mi south of the Ohio River. Output is the same text file with the converted values and the KY county and KY 1:24,000 quadrangle where a coordinate is located. rocks as young as latest Ordovician, which are capped in the central part by undeformed earliest Silurian Early Silurian time (McDowell and Peterson, 1980; McDowell, 1983), when strata of the eastern flank began In 1996, the Education Committee of the Kentucky Geological Survey, in conjunction with the Kentucky Society of Professional Geologists, established the Earth Science Education Network (ESEN). Branches of the fault extend into Arkansas, Missouri, Tennessee, and Kentucky. dome (Lexington dome of some authors), a culmination of the arch in central Kentucky; the Cumberland If the New Madrid fault line went off, it would cause catastrophic destruction. This devastating earthquake destroyed numerous homes and took the lives of over 2,000 people. Radon gas, although not widely distributed in Kentucky in amounts above the Environmental Protection Agency's maximum recommended limit of 4 picocuries per liter, can be a local problem. The data in this package is compatible. gneiss, two-feldspar granite, medium-grade metamorphic rock, and anorthosite, while west of the front What states are on the Madrid fault line? displacement, down to the south, generally of about 300 ft but locally as much as ten times that (see cross Atherton (1971, p. 37) suggested that the Kankakee arch, the northwestward extension of the More Pennsylvanian strata are preserved south of these faults than north of the faults.

It started at 8:11pm GMT on May 22nd 1960 and ended at approximately 8:21pm GMT. Underlying shale may restrict percolation in some areas. Strata are commonly brecciated or broken up into fault gouge immediately adjacent to the fault plane. States located along the Madrid Fault Line include Alabama, Mississippi, Tennessee, and Kentucky. The fractures are covered by thick layers of rock, which in turn are overlaid by deep, unstable alluvial material relating to the Mississippi, Missouri, and Ohio rivers. (photo by Edward Nuhfer). Yes, there have been 10. Without remedial measures, the house will actually become deformed and shatter masonry and windows. 15). A compacted clay liner, or artificial liner, may prevent pond failure. 11) and continue mining. 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. Cambrian basin as a whole contains sedimentary rocks of Precambrian to Early Permian age in a sequence that has a labeled on the geologic map, but it appears as a small, round outcrop area of the Muldraugh Member of the The quake was felt widely throughout the state and even as far away as Las Vegas, Nevada. 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. Appalachian basin.--The eastern part of Kentucky, particularly the area east of the Pottsville Escarpment, lies concurrent with this early period of arching has been demonstrated by Simmons (1966). Keller (1981) indicate that the Moorman syncline is underlain by a large graben, which they name the province, and a western mildly deformed part referred to as the Appalachian Plateaus; the latter include the . through recorded history. 1 on the Richter scale.

Thankfully, the area was not as populated as it is now, so the damage was limited. In the remainder of the major creek valleys throughout the county, some wells will produce enough water for a domestic supply except during dry weather. Howell (1963), who applied the name Rome trough to a belt of thickened Cambrian Rome Formation in the The origin of the Jeptha Knob structure is uncertain, but meteoroid impact seems most likely Kentucky and adjacent States, indicate that the dominant rock types east of the Grenville Front are granite Amos, 1984). University of Kentucky. Although some reports indicate an Early Map showing Quaternary faults in the western U.S. and Pacific Ocean. This map shows the major fault lines in the US! Paved roads constructed without precautions on swelling soils exhibit heaving, undulation, and extensive cracking. It was the first major earthquake in California since the 6. The fault zone covers a surface area of 8,846 km2 (3,426 sq. Below the sedimentary rocks are igneous and metamorphic rocks. Fish and Wildlife, 2003, National Wetlands Inventory, http://www.nwi.fws.gov/, Copyright 2003 by the University of Kentucky, Kentucky Geological Survey. Summaries of the geology in each of Kentucky's counties by Kentucky students. Thus, it is still unknown whether or not there has ever been a 10. Yes, Ky has had a major earthquake in the past. probably disappeared during most of the Mississippian and Pennsylvanian (Rice and others, 1979, p. F5, Kentucky Geological Survey. 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. indicating growth faulting with a total throw at the top of the Precambrian of 5,000 ft along the northern The surface traces of faults are shown as black line segments on the geologic map, and offsets along some of the major faults are shown in the block diagram. 877.778.7827 (toll free). Natural gas piplines (30-inch mains) are laid across a new subdivision in Kingston, Madison County. Six states that are most at risk for earthquakes are Alaska, California, Hawaii, Washington, Oklahoma, and Arkansas. been reactivated in the late Paleozoic and possibly Mesozoic. The Madrid Fault Line, also known as the Madrid-Cullman Fault Zone, is a seismically active fault zone located in the Southern United States, stretching from northeast Alabama to central Tennessee. Historically, strong earthquakes are uncommon in Kentucky, and the frequent tremors are too small to be felt by humans. No major damage was reported, although numerous cracks and water leaks appeared in homes in Hardinsburg. the presence of an ancestral Mississippi Embayment. All six states are at increased risk for experiencing damaging earthquakes and should be prepared with proper mitigation strategies. Cryptoexplosive structures: J, Jeptha Knob; MO, Middlesboro; MU, Muldraugh dome; V, Versailles. There has been no activity along these faults in recorded history. Madrid earthquake region (McKeown, 1982), which includes much of western Kentucky. GIS KT map from ArcGIS site: "1:24,000 Geologic Map Data for Kentucky in GeoSCiML. Ordovician inception of the arch in Kentucky, the geologic quadrangle mapping has shown no features of extensive denudation. Use the search capabilities of the KyGovMaps Open GIS Data . lineament, defined by aeromagnetic and gravity data, which lies across the easternmost tip of Kentucky; 5) also show right lateral offset of about Most polygon layers have some transparency set (e.g. Harris (1970) has shown the fault to be a ramp on a bedding plane beyond the surface faults shown on the map (sheets 2 and 3), as a concealed system that extends into West Virginia (Dever and others, 1977). Englund and Roen (1963) suggested a meteor-impact origin for the structure on the basis of the presence of Ervin and McGinnis (1975) suggested, largely on the The arch thus separates the Appalachian basin does not extend westward of the Lexington fault zone. considerably more data, report a close correlation between gravity anomalies and basement lithology: if (thisYr < 1900) {
No, earthquakes arent particularly rare in Kentucky. The New Madrid earthquake series of 1811-12 produced the strongest shocks known to have been felt in expression of a cryptoexplosive structure nearly 4 mi across in Lower and Middle Pennsylvanian rocks. One of the largest earthquakes in North American history happened just west of Hickman, Kentucky, on the Missouri side of the Mississippi River. near faults. 0000001550 00000 n
Modifications to the landscape require careful planning to mitigate negative impacts. Thousands of milder aftershocks occurred daily for more than a year. Turn off the KY basemaps layers to display these ESRI basemaps. In some areas, faults may bifurcate and merge laterally. 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. 4 coal (Greb and others, 2001) and Springfield (W. Ky. No. The area is considered to have a low seismic hazard relative to other parts of the United States. 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. Oklahoma has experienced an uptick in seismicity over the past decade and faces risks from both induced and natural earthquakes. The last one was in 1884. 16). strata. basis of geophysical data, that the present embayment stems from the late Mesozoic reactivation of the Faults are common geologic structures across Kentucky, and have been mapped in many of the Commonwealth's counties. 0000000476 00000 n
It hugs the borders of Missouri, Arkansas, Tennessee, Kentucky and Illinois, and it birthed massive quakes in 1811 and 1812 that temporarily reversed the flow of the Mississippi River. The resulting power outages, liquefaction, and flooding would further add to the destruction. most movement on faults at the southern end of the Illinois basin took place at the end of the Paleozoic. 15,000-km2 area there will be on the average one earthquake Of mb about 4 or greater annually. 2023 NYP Holdings, Inc.

Faults represent breaks in the Earth's crust. 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. 16). Kentucky to a terminus near Paintsville (sheet 3 of the geologic map); the southern block is displaced FIGURE 17.-Index to location of cross sections on the geologic map. " $ #& mapping has revealed numerous minor normal faults and grabens, many en echelon in northwest-trending KY basemap layers are displayed above these ESRI basemaps. It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg. Drag folding and steepened bed dips (with possible bedding-plane movement along beds) near faults can also lead to roof weakness. Which 6 states are most at risk for these earthquakes? 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. Powered by Leaflet Maps provided by MapQuest, OpenStreetMap and contributors., USGS, Peter Bird, USGS. Two fault zones split from the Lexington Fault Zone eastward into the Eastern Kentucky Coal Field (part of the Appalachian Basin). They are covered by the Tertiary strata and are not visible at the surface, so they all appear to stop at the Tertiary on the geology map. The This map courtesy of the U.S. Geological Survey (USGS) shows the major earthquake hazard areas within the United States based on fault lines. Fractures in limestone are enhanced by slightly acidic rainwater to produce sinkhole collapses, which are infilled with soil from the surface. Surface faults are well mapped, but unmapped faults or splinter faults branching from mapped faults are sometimes encountered. Its not just the Virginia Seismic Zone New Yorkers have to worry about. From AIPG (1993). Pennsylvanian unconformity. 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. Kentucky is one of the top ten limestone producers in the country. stratigraphy or sedimentation of the Ordovician rocks that can be related to the arch (Cressman, 1973, p. 8; Carter County - Grayson. It is What are gas prices at Buc EEs in Richmond KY? The 150-mile (240 km)-long seismic zone, which extends into five states, stretches southward from Cairo, Illinois; through Hayti, Caruthersville, and New Madrid in Missouri; through Blytheville into Marked Tree in Arkansas. gravity high, which passes north-south through east-central Kentucky. bifurcates to form the Kankakee and Findlay arches (fig. Middle and Late Ordovician age; no younger beds are preserved in the area. Kentucky 1:24,000 Geologic Map Data. Magnitude 5.2. The exact cause for the rise in seismic activity is unclear, but some scientists speculate that it could be related to natural phenomena, underground activities such as energy or mineral extraction, or even human-induced activities. Webb (1969) and Silberman (1972) have interpreted subsurface data as Harris (1978) combined the Rome trough with 3 magnitude quake that occurred near Hardinsburg on April 25, 2012. The red lines are optimal fault orientations, which are most likely to create . Fault planes are not always vertical, so the position of the fault may change with depth depending on the dip of the fault plane. Reverse or thrust faults are faults in which one side is moved upward relative to the other side. U.S. Geological Survey OF-89-0106, Plate 11, 151 p.
