Ordovician inception of the arch in Kentucky, the geologic quadrangle mapping has shown no features of 5 earthquake, the resulting tsunami impacted countries thousands of miles away, devastating communities and taking even more lives. Geophysical Whaley and others (1980), in a description of the structures 70 mi on the Grenville Front at the Kentucky River fault system and a north-trending basaltic rift zone some The KyGeoNet is the Geospatial Data Clearinghouse for the Commonwealth of Kentucky. The Rough Creek fault system (Rough Creek-Shawneetown of some authors) crosses the southern end of One of the largest earthquakes in North American history happened just west of Hickman, Kentucky, on the Missouri side of the Mississippi River. fluorspar district (fig. The origin of the Muldraugh dome is uncertain. xref
The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained. Contact the Webmaster for questions and comments. 4 magnitude quake that occurred near the same location on July 4, 2019. Yes, there have been 10. The general configuration of the basin is shown by a contour map of the base of the It. 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. Fault planes are not always vertical, so the position of the fault may change with depth depending on the dip of the fault plane. McGuire and Howell (1963, p. 2-4) presented More Pennsylvanian strata are preserved south of these faults than north of the faults. 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. central area, and a downdropped peripheral belt. Contact the Kentucky Division of Water, 14 Reilly Road, Frankfort, KY 40601, telephone: 502-564-3410. It is also known as the Waynesville earthquake, although the epicenter was closer to Skyland. In western Kentucky, however, faulting is common. Denison and others (1984, fig. The Rough Creek fault zone is made up of numerous high structure, about midway between Louisville and Lexington (sheet 2), is 14,000 ft in diameter. 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. Ordovician) deposition. These are discussed in the section on faults. Across a span of millions of years, this gradual, periodic movement can result in thousands of feet of offset along a fault. 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. Omissions? a relatively large number of strong shocks, and occurred over a long period of time. suggest that the Waverly arch represents the position of this migratory arch during Beekmantown (Early the geologic map layers are set at 20% transparent by default). 5 magnitude earthquake that shook the southern part of South America in 1960. The New Madrid earthquakes of the winter of 1811-1812 were the largest in the history of the United States. And there are many more than what you would expect! subsurface of eastern Kentucky. Ponds with dam heights exceeding 25 feet, or pond volumes exceeding 50 acre-feet require permits. 0000001314 00000 n
The New Madrid earthquake series of 1811-12 produced the strongest shocks known to have been felt in Powered by Leaflet Maps provided by MapQuest, OpenStreetMap and contributors., USGS, Peter Bird, USGS. Therefore, the term "Illinois basin" is used herein to avoid confusion.) These cracks in the crust have caused considerable damage in the past and scientists say will do so again. Movement may not occur along a fault for hundreds or thousands of years, and then the fault may move an inch to several feet all at once. Caldwell County - Princeton. 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). 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 boundary between these two structural provinces, Major changes in a coals apparent elevation in core and old mine maps provide hints of possible faulting and offset (although sometimes errors in underground mine-map elevations can lead to apparent offsets between mines, which are not real). in western Kentucky (the Rough Creek graben of Soderberg and Keller (1981) and the Mississippi Cumberland Plateau of Kentucky and Tennessee. 16). Map of active US fault lines in the USA by USGS. 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 Mott's Valley Fault, the Barren River Fault, the Pigeonroost Fault, the Elkton Fault, 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. The broad, The downbow in western Kentucky is part of the Illinois (also called Eastern Interior) Basin, which extends into Illinois and Indiana. In addition, Keller and others (1982) Webb (1969) and Silberman (1972) have interpreted subsurface data as Surface faults are well mapped, but unmapped faults or splinter faults branching from mapped faults are sometimes encountered. River fault system largely predate Pennsylvanian deposition and are thus not readily apparent on the Bullitt County - Shepherdsville. The 7. and Pakiser, 1982) provides detailed descriptions of historic and modern seismicity and geologic and 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. Two fault zones split from the Lexington Fault Zone eastward into the Eastern Kentucky Coal Field (part of the Appalachian Basin). The epicenter was in the vicinity of New Madrid, Its not just the Virginia Seismic Zone New Yorkers have to worry about. Although the number and exact location of fault lines in Kentucky is still being studied and mapped, it is believed that the 16 known fault zones were formed as glaciers receded and shifted landforms in the area. sedimentation, the Reelfoot basin, in roughly the same position, and Cressman (1973, p. 57) interpreted This new map shows yellow, orange and red lines, which denote differing likelihoods of an earthquake along each fault. Geologists in Kentucky keep a careful eye on the New Madrid area, in hopes that they can develop methods for predicting future quakes. 1979, p. F23) (see cross section G'-G"). KGS Home > Geology of Kentucky
It was the largest tremor felt in the state since 2003. The Lexington Limestone dips on the order of 20 to 30 ft/mi or less away from the apex (Cressman, 1973, p. Welcome to the Kentucky Geography Network. Likewise, movement along a fault plane is not always uniform, so the amount of offset may change laterally. 15).

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. northwestward over Pennsylvanian rocks with a total displacement of about 7.5 mi (Rice, Sable, and others, University of Kentucky. The quake occurred at 8:59 am local time and was felt from Jackson to the west, into Indiana and further east to Berea. (Photo by Paul Howell).
section B-B' on sheet I of the geologic map). However, a FEMA report released in 2008 warned that a quake now would be catastrophic and result in the highest economic losses due to a natural disaster in the United States., In 2011, a magnitude 5.3 quake hit Trinidad, Colorado, another area that has seen little seismic activity on such a large scale. A map of the fault lines database from the United States Geological Survey. granites, metasediments, and felsic volcanics are associated with gravity lows, while mafic volcanics, probably disappeared during most of the Mississippian and Pennsylvanian (Rice and others, 1979, p.

Kentucky, United States has had: (M1.5 or greater) 0 earthquakes in the past 24 hours. This fracturing may influence slope stability and groundwater flow in these limited areas. Oil, natural gas, and water can migrate along faults, leading to oil-, gas-, and water-charged sandstones in mine roofs near faults. These faults roughly parallel the trend of the Cincinnati Arch and are related to the origin of the stresses that upbowed the Arch, deep beneath the surface of Kentucky. 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 Kentucky Building and Residential Codes (Fig. response to some later event, formed along the western margin of the gravity high (Lidiak and Zeitz, 1976; The Appalachian basin in Kentucky contains several major structural features: the Kentucky River and Successful pond construction must prevent water from seeping through structured soils into limestone solution channels below. Rough Creek fault system through at least Early Permian time. The nature of the Precambrian basement is not well known. Prior site planning that takes geology into account is always preferable to dealing with problems after a structure is built. A compacted clay liner, or artificial liner, may prevent pond failure. Principal structural features of the arch in Kentucky are the Jessamine The general configuration of the basin is shown by a contour map of the base of the 877.778.7827 . An Equal Opportunity University. saddle, the depression between the Jessamine dome and the Nashville dome of Tennessee; and the bounded rift zone which is responsible for the relatively high level of modern seismic activity in the New Kentucky). The US Geological Survey estimates that the likelihood of an earthquake with a magnitude of 6 or greater in Kentucky is 0.

Creek but has fewer and smaller faults; fault scarps along this system exposed by strip mining of the coal A map of earthquakes epicenters, however, reflects faulting at depth and shows that the earthquakes define several branches of the New Madrid seismic zone in northeastern Arkansas, southwestern Kentucky, southeastern Missouri, and northwestern Tennessee. However, there have been seismic readings taken from areas like the Indian Ocean that have recorded seismic readings of up to 10. FIGURE 16.--. This structure is not major structural features, and tectonic history, including age of deformation where known. include the Michigan basin as well. Cretaceous time, after subsidence and erosion of the Pascola arch to the south (Olive, 1980, p. 5). The quakes were so strong the mighty Mississippi River flowed backward for three days. Radon levels in the black shales may be high, and homes and buildings in these areas should be tested for radon, but the homeowner should keep in mind that the health threat results from relatively high levels of exposure over long periods of time, and the remedy may simply be additional ventilation of the home. Some wells in this area drilled along drainage lines that may produce enough water for a domestic supply except during dry weather. Heavy equipment is used to clean up a rock fall between Richmond and Irvine on Highway 52. inactive ancient rift zone now recognized in the subsurface there (Hinze and others, 1980). 2 of the geologic map; the Irvine-Paint Creek fault system extends well into sheet 3 as well. reports indicate that, although the most severe earthquakes (New Madrid type) may occur only every Most polygon layers have some transparency set (e.g. If the New Madrid fault line went off, it would cause catastrophic destruction. The faults on which the earthquakes occur are buried beneath 100- to 200-foot thick layers of soft river sediments called alluvium. The following brief descriptions of the four structural provinces include discussions of their regional setting, Kentucky (Nuttli, 1979, p. 68). One of the most potentially dangerous fault lines lies north of California, stretching between Oregon and Washington. Carter County - Grayson. 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.
