0000001314 00000 n Discontinuities and obstacles:Where a fault intersects a mined coal seam, the coal seam will be offset, generally causing an abrupt end to the seam into rock on the other side of the fault plane. 0 earthquakes recorded in history. Dams should be constructed of compacted clayey soils at slopes flatter than 3 units horizontal to 1 unit vertical. and Zietz, 1976), marking the southern boundary of the Moorman syncline, is similar in form to the Rough The Moorman syncline extends into southern Illinois, where it is known as the Eagle 2 that took place near Cawood in 1909. These are discussed in the section on faults. We are currently working on a solution for this issue. 0000000476 00000 n The. 38) reported wells penetrating brecciated Knox dolomites and cherts below coherent Silurian dolomite, 30 mi wide, which coincides with gravity and magnetic highs and extends from south-central Kentucky into Legend Issues: Some legend items may not print in the layout. Remedies vary from mere maintenance that keeps drainage away from the house to expensive reconstruction of foundations. Right: With time, expanding soils exert several tons per square foot of pressure on the foundation and shallow pilings. Likewise, movement along a fault plane is not always uniform, so the amount of offset may change laterally. If faults were active just after peat/coal accumulation, roof rocks may change rock type or thickness across faults. Keller and others (1982, p. 218), on the basis of In seismic exploration, energy waves are directed into the ground and are reflected by the different grouping of rocks back up to the surface and recorded. Amos, 1984). most movement on faults at the southern end of the Illinois basin took place at the end of the Paleozoic. Map of active US fault lines in the USA by USGS. The Rough Creek fault zone is made up of numerous high All six states are at increased risk for experiencing damaging earthquakes and should be prepared with proper mitigation strategies. 16). Ordovician inception of the arch in Kentucky, the geologic quadrangle mapping has shown no features of In Mississippi, the fault line passes through the following counties: Tishomingo, Itawamba, Pontotoc, Prentiss, as well as part of Tippah and Alcorn counties. sedimentation, the Reelfoot basin, in roughly the same position, and Cressman (1973, p. 57) interpreted gneiss, two-feldspar granite, medium-grade metamorphic rock, and anorthosite, while west of the front In areas overlying limestone, septic system leaks can occur through fractures in the limestone, contaminating groundwater. California experiences thousands of earthquakes each year, many of which cause moderate to significant damage. Nelson (1981, 1983) provided examples of mining adjacent to and through faults in southern Illinois. Tennessee and Alabama. Data set is derived from the 7.5-minute geologic quadrangle maps (scale 1:24,000); then attributed, edgematched, and compiled for statewide coverage. In addition to the physical destruction caused by the 9. https://mrdata.usgs.gov/services/wfs/sgmc2. Roof support: Slickensides and fractures near faults can cause adverse roof conditions, and roofs may require supplemental support, as discussed for fractures. 16), resulting in the A clayey soil pond liner is placed in loose, moist layers nine inches thick and compacted in six passes with a sheepsfoot roller. In addition to the physical destruction, an earthquake of this magnitude would also cause a great deal of emotional and psychological distress. Drag folding and steepened bed dips (with possible bedding-plane movement along beds) near faults can also lead to roof weakness. Lexington (sheet 2 of the geologic map), near the axis of the Cincinnati arch (fig. xref Dataset Size: 0 bytes. Thanks for contacting us. var d = new Date(); Cross sections C-C' through F-F' on sheet 2 of the geologic map Geologists know what the rocks in the subsurface look like from data gathered during drilling beneath the surface for oil, natural gas, coal, industrial minerals, and water resources, and from seismic exploration. basin as a whole contains sedimentary rocks of Precambrian to Early Permian age in a sequence that has a province, and a western mildly deformed part referred to as the Appalachian Plateaus; the latter include the Calloway County - Murray. Omissions? 16). 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. surveys of the area (Black and others, 1977) show a close relationship between gravity and magnetic data Getting the basin filled with water as soon as possible after construction prevents drying and cracking, and possible leakage, of the clayey soil liner. Ages range Deposition of the Upper The intensity of the largest of the three main shocks has been given as XII, and the body-wave rifting in eastern Kentucky (Rome trough: Harris, 1975; Ammerman and Keller, 1979) and post-Ordovician basis of geophysical data, that the present embayment stems from the late Mesozoic reactivation of the exposed and subjected to erosion only briefly at the end of the Ordovician, during the period of intensive Engineering design principles are employed in roadways and bridges to prepare for such situations. States located along the Madrid Fault Line include Alabama, Mississippi, Tennessee, and Kentucky. This article was most recently revised and updated by, https://www.britannica.com/place/New-Madrid-Seismic-Zone, Missouri Department of Natural Resources - Facts about the New Madrid Seismic Zone. 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. 5 earthquake lasted approximately 10 minutes. FIGURE 15.--Structural setting of the eastern midcontinent. The Irvine-Paint Creek fault system extends eastward from central recurrence curve plotted for the New Madrid seismic zone (Nuttli, 1979) shows that, for example, in a The resulting power outages, liquefaction, and flooding would further add to the destruction. While every effort has been made to follow citation style rules, there may be some discrepancies. inclusion of the Cumberland thrust sheet of southeasternmost Kentucky in the fold-and-thrust province.

USGS Interactive Fault Maps. Cincinnati arch (fig. 16; not labeled on the geologic map) occupies most of central Kentucky, as There are numerous faults in Kentucky. River fault system largely predate Pennsylvanian deposition and are thus not readily apparent on the The New Madrid earthquakes of the winter of 1811-1812 were the largest in the history of the United States. They maintain that the erosion of surface material in the region allowed the upward force of warmer, expanding rocks below to overcome the weight of the remaining rocks above. Pennsylvanian unconformity. from the geologic quadrangle mapping. 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. and Pakiser, 1982) provides detailed descriptions of historic and modern seismicity and geologic and Newton, J.H., McDonald, H.P., Preston, D.G., Richardson, A.J., and Sims, R., 1973, Soil survey of Madison County, Kentucky: U.S. Department of Agriculture, Soil Conservation Service, 103 p.

Blue Grass Area Development District, 2003. 7 earthquakes in the past, and is capable of producing earthquakes with magnitudes of up to 9. Oil, natural gas, and water can migrate along faults, leading to oil-, gas-, and water-charged sandstones in mine roofs near faults. Rough Creek graben, that was active as early as latest Precambrian or earliest Cambrian time and that has On Dec. 16, 1811, a magnitude 7.7 earthquake hit the New Madrid fault line, which lies on the border region of Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee and Mississippi. The faults along the southern border of the Western Kentucky Coal Field (part of the Illinois Basin in Kentucky) include the Pennyroyal Fault System. Breckinridge County - Hardinsburg. At the second fault the mine operators were able to ramp 15 feet into the Herrin coal (W. Ky. No. Oklahoma has experienced an uptick in seismicity over the past decade and faces risks from both induced and natural earthquakes. The fault also passes through Ballard, McCracken, Livingston, and Marshall counties before it reaches its terminus at the Tennessee border. Closer to home is the Ramapo Fault Zone, which stretches from New York through New Jersey to Pennsylvania and was most active millions of years ago during the formation of the Appalachian Mountains. (1982) points out that the New Madrid earthquakes were characterized by a particularly large "felt area" and Earthquakes still occur on these faults, but most are so small that they are barely felt. Illinois basin.--The Illinois basin is a major structural downwarp in the eastern midcontinent, occupying large U.S. Illustration prepared by Paul D. Lowman Jr., NASA Goddard Space Flight Center. Thousands of earthquakes have been recorded in this region since 1974. Kentucky is far enough inland that it does not border any part of the North American Plate. Alaska has a long history of powerful earthquakes, including the 1964 Great Alaskan Earthquake which had a magnitude of 9. The time of formation of the Cincinnati arch in central Kentucky has recently been discussed by McDowell parts of Illinois, Indiana, and Kentucky and lying between the Ozark uplift on the west and the Cincinnati Cambrian-Lower Ordovician Knox Group in eastern Kentucky was significantly affected by continuing 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. Welcome to the Kentucky Geography Network. 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. We've received your submission. Prior site planning that takes geology into account is always preferable to dealing with problems after a structure is built. Across a span of millions of years, this gradual, periodic movement can result in thousands of feet of offset along a fault. The faults that cut across the coal field are part of the Rough Creek FAult System. To select data from a rectangular area, hold the Ctrl key (use Cmd key on Macs) and drag the pointer. place of about 35,000 ft (Colton, 1970, p. 13). Kentucky). 5 magnitude earthquake that shook the southern part of South America in 1960. 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. This was followed by Middle(?) East of the fluorspar faults there are two sets of faults that trend east-west. It. 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.. 11) and continue mining. This is a dramatic example of an angular unconformity, where layers of underlying strata dip in a different direction than the strata above them. //--> An Equal Opportunity University. Successful pond construction must prevent water from seeping through structured soils into limestone solution channels below. Use the search capabilities of the KyGovMaps Open GIS Data . southeasternmost Missouri, northeasternmost Arkansas, and adjacent areas of westernmost Tennessee and granites, metasediments, and felsic volcanics are associated with gravity lows, while mafic volcanics, There are no active plate tectonic movements in this area at the present time, and as such, there are no active fault lines. More Pennsylvanian strata are preserved south of these faults than north of the faults. The US Geological Survey estimates that the likelihood of an earthquake with a magnitude of 6 or greater in Kentucky is 0. Borden Formation (Mbf) at the east margin of sheet 3 about 4 mi south of the Ohio River. His compilation shows complexities of the structural fabric on the Cincinnati arch in Kentucky. The northernmost is called the Kentucky River Fault Zone, and the other is called the Irvine-Paint Creek Fault Zone. Beneath the Surface [Geologic Structures]. Cumberland Plateau of Kentucky and Tennessee. by the Kentucky Geological Survey, The Appalachian basin is divided structurally into an eastern highly deformed part, the fold-and-thrust Kentucky, United States has had: (M1.5 or greater) 0 earthquakes in the past 24 hours. Embayment across a gentle, northwest-trending arch (Heyl and others, 1965; Pinckney, 1976; Trace and The death toll likely would have been much higher if the quake had lasted any longer. 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. 0. FIGURE 17.-Index to location of cross sections on the geologic map. P, Elliott County peridotite intrusion. McGuire and Howell (1963, p. 2-4) presented geophysical features of the region that may be useful in understanding the nature of the seismicity. Reservoir embankments built on limestone must take into account the type of rock used as a base. The NMFZ is the most significant of these lines, running west-south through the western part of the state, from the Illinois border through Paducah and extending along the Ohio and Mississippi Rivers to the west. Carroll County - Carrollton. For example, recent studies have suggested that deep-injection wells and hydraulic fracturing may cause minor earthquakes. Mitchell County Earthquake - July 8, 1926. 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. Early Silurian time (McDowell and Peterson, 1980; McDowell, 1983), when strata of the eastern flank began 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. Last modified Kentucky (fig. Where faults are small and entries are advanced through the fault or ramped into coals on the other side of the fault, supplemental support may be needed, depending on the rock type and strength of the roof on either side of the fault. Appalachian basin.--The eastern part of Kentucky, particularly the area east of the Pottsville Escarpment, lies Surface faults are well mapped, but unmapped faults or splinter faults branching from mapped faults are sometimes encountered. Freeman (1951, p. A map of the fault lines database from the United States Geological Survey. 4 magnitude quake that occurred near the same location on July 4, 2019. response to some later event, formed along the western margin of the gravity high (Lidiak and Zeitz, 1976; The ground shaking that would result could cause buildings to collapse, gas pipelines to rupture, and transportation routes to be blocked. Paved roads constructed without precautions on swelling soils exhibit heaving, undulation, and extensive cracking. 16). 16). Although the arch was a positive structural element through much of the Paleozoic, strata were to be a positive feature in Devonian time, but its influence on sedimentation in Kentucky waned and digital geologic map information service, 310 Columbia Ave, 228 Mining and Mineral Resources Building, University of Kentucky, Lexington, KY 40506-0107. No, there is no tectonic plate located in Kentucky. 0000000016 00000 n While the state is not located in an area that is highly prone to earthquakes, it is located in an area with a moderate level of seismic activity. Geophysical regional facies relationships of the Lexington Limestone of central Kentucky and adjacent States as implying Strata are commonly brecciated or broken up into fault gouge immediately adjacent to the fault plane. Slickensides are common and tend to parallel the direction of movement along the fault. %PDF-1.4 % border of the trough, which coincides with the Kentucky River fault system. 15). Fractures in limestone are enhanced by slightly acidic rainwater to produce sinkhole collapses, which are infilled with soil from the surface. suggesting a "crypto-volcanic" nature. Faults are common geologic structures across Kentucky, and have been mapped in many of the Commonwealth's counties. Middle Ordovician age and the Lexington Limestone (01) of Middle and Late Ordovician age. Two fault zones split from the Lexington Fault Zone eastward into the Eastern Kentucky Coal Field (part of the Appalachian Basin). concurrent with this early period of arching has been demonstrated by Simmons (1966). was a shoal in late Middle and early Late Ordovician time. Faulting 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. by the Kentucky Geological Survey, University of Kentucky. KGS Home > Geology of Kentucky Thankfully, there were only minor reported injuries and no deaths associated with the quake. 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. 16). } The HWmo6_0|I(8JSKN jSmEc&q2Hxsw:Bc$SLHqm(cd?v%:X(rx7LPd)sT|'r|K:G% _ c%*H4'%QH%o;desKS*9."|\ '-[QoE0(Z7`R 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. Rough Creek fault system through at least Early Permian time. Please refer to the appropriate style manual or other sources if you have any questions. Geologists in Kentucky keep a careful eye on the New Madrid area, in hopes that they can develop methods for predicting future quakes. Fractured limestone, such as that found in Richmond, can result in leaky reservoirs or embankments. King and Zeitz (1978) have recognized the New York-Alabama basement Geophysical studies by Soderberg and One of the largest earthquakes in North American history happened just west of Hickman, Kentucky, on the Missouri side of the Mississippi River. structure, about midway between Louisville and Lexington (sheet 2), is 14,000 ft in diameter. 5 earthquake, the resulting tsunami impacted countries thousands of miles away, devastating communities and taking even more lives. County geology. Turn off the KY basemaps layers to display these ESRI basemaps. The Mississippi Embayment is currently delineated by the Cretaceous and Tertiary coastal plain strata (see http://kgs.uky.edu/kgsweb/download/wrs/MADISON.pdf, Water well information is available at: http://wris.state.ky.us/website/kgs/viewer.htm. Most of this data has been summarized by McGuire and 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. startxref These fractures can also contribute to roadway failure. 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. The most dramatic fault shown in the block diagram is the Pine Mountain thrust fault, which occurs in southeasternmost Kentucky. The Kentucky Building and Residential Codes (Fig. migration of an arch through northeastern Kentucky in the Late Cambrian and Early Ordovician; they in western Kentucky (the Rough Creek graben of Soderberg and Keller (1981) and the Mississippi 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. Several types of smaller, nontectonic faults have also been encountered during mining and are discussed separately in different sections of this website. 2023 NYP Holdings, Inc.
