Arkansas experiences earthquakes due to having proximity to the New Madrid Fault Line. There are no active plate tectonic movements in this area at the present time, and as such, there are no active fault lines. Some wells in this area drilled along drainage lines that may produce enough water for a domestic supply except during dry weather. 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. Mitchell County Earthquake - July 8, 1926. Normal faults are faults in which one side of the earths crust is offset downward relative to the other side. J8T< B%3 F>YM^S=d0BqeCCu &8E2AYx`LR {]T)|x% ;". northeastern Kentucky (Dever and others, 1977). Six states that are most at risk for earthquakes are Alaska, California, Hawaii, Washington, Oklahoma, and Arkansas. Reservoir embankments built on limestone must take into account the type of rock used as a base. field (sheet I of the geologic map). several thousand years (McKeown, 1982, p. 1), damaging earthquakes in the region have been common initiation of the Illinois and Appalachian basins. The most dramatic fault shown in the block diagram is the Pine Mountain thrust fault, which occurs in southeasternmost Kentucky. 0000001642 00000 n Thousands of milder aftershocks occurred daily for more than a year. saddle, the depression between the Jessamine dome and the Nashville dome of Tennessee; and the Trends: Faults tend to have linear to slightly curving trends, so orientations can be projected in advance of mining. Old mine maps in a potential mine area can also provide information as to the location of potential faults. Harris (1970) has shown the fault to be a ramp on a bedding plane example, Sable (1979), as the Eastern Interior basin; others, such as Snyder (1968), use the latter term to However, there have been seismic readings taken from areas like the Indian Ocean that have recorded seismic readings of up to 10. For example, in 1980 New Madrid experienced a magnitude 5. amphibolites, and mafic granulites are found in the vicinity of highs. does not extend westward of the Lexington fault zone. response to some later event, formed along the western margin of the gravity high (Lidiak and Zeitz, 1976; been described by Black (1964). include the Michigan basin as well. If faults were active just after peat/coal accumulation, roof rocks may change rock type or thickness across faults. ], [Click on image to see a larger version in a new window.]. It has produced magnitude 8 to 8. The Rough Creek fault zone is made up of numerous high Principal structural features of the arch in Kentucky are the Jessamine While stronger quakes can still occur, they are rare and damage is usually minimal. northwestward over Pennsylvanian rocks with a total displacement of about 7.5 mi (Rice, Sable, and others, His compilation shows complexities of the structural fabric on the Cincinnati arch in Kentucky. Yes, Ky has had a major earthquake in the past. County geology. The general configuration of the basin is shown by a contour map of the base of the Published descriptions or examples of faults in Kentucky coal mines cite faults through the Western Kentucky No. (The Illinois basin is referred to in some reports, for The faults on which the earthquakes occur are buried beneath 100- to 200-foot thick layers of soft river sediments called alluvium. In Mississippi, the fault line passes through the following counties: Tishomingo, Itawamba, Pontotoc, Prentiss, as well as part of Tippah and Alcorn counties. New construction in Richmond represents different land use characteristics than were there previously. 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. Geophysical studies of the Moorman syncline by by the Kentucky Geological Survey, University of Kentucky. dome (Lexington dome of some authors), a culmination of the arch in central Kentucky; the Cumberland The present structural relief on the arch results mostly from latest Paleozoic The northernmost is called the Kentucky River Fault Zone, and the other is called the Irvine-Paint Creek Fault Zone. 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. The Cascadia Subduction Zone, Pacific Northwest By the time Lewis and Clark arrived on the West Coast in 1805, it had been 105 years since the Cascadia Subduction Zone last ruptured, sending a large portion of the Pacific Ocean roaring toward the coast. Thanks for contacting us. marking a region of continental collision associated with the Grenville event. Creek and Pennyrile fault systems, the Moorman syncline, and faults in and around the Illinois-Kentucky Located in far Western Kentucky is one of our most popular outdoor areas: Land Between The Lakes (LBL). No, there is no tectonic plate located in Kentucky. Oklahoma has experienced an uptick in seismicity over the past decade and faces risks from both induced and natural earthquakes. Faults represent breaks in the Earth's crust. 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. 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. 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). An uplifting experience that will not be appreciated! 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). Yes, there have been 10. 15), rose at the close of Early Ordovician time. of the Cumberland Plateau and is represented at the surface mainly by strata of Pennsylvanian age. Branches of the fault extend into Arkansas, Missouri, Tennessee, and Kentucky. Other leakage prevention measures include synthetic liners, bentonite, and asphaltic emulsions. displacement, down to the south, generally of about 300 ft but locally as much as ten times that (see cross These 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. Sparks, T.N., Dever, G.R., Jr., and Anderson, W.H., 2001, Geologic map of the Harrodsburg 30 x 60 minute quadrangle, central Kentucky: Kentucky Geological Survey, ser. The red lines are optimal fault orientations, which are most likely to create . Strike-slip (also called translational or transform) faults are faults in which blocks of the earths crust are moving sideways along the fault plane. Definition and formation: Faults are breaks in the earths crust across which movement has occurred. southern part of the Illinois basin lies in Kentucky and includes the Pennsylvanian strata of the western coal East of the fluorspar faults there are two sets of faults that trend east-west. FIGURE 16.--. Magnitude 5.2. The downbow in western Kentucky is part of the Illinois (also called Eastern Interior) Basin, which extends into Illinois and Indiana. Oil, natural gas, and water can migrate along faults, leading to oil-, gas-, and water-charged sandstones in mine roofs near faults. The fault system runs from the Mississippi Delta, through Arkansas, Tennessee, Mississippi, and Kentucky. Dataset Size: 0 bytes. Contact the Webmaster for questions and comments. var d = new Date(); Seismologists say we can expect the next one any day now. Fun times! 133 0 obj <> endobj (1983, p. 24). failed arm (the "Reelfoot rift") of a late Precambrian triple junction. The nature of the Precambrian basement is not well known. In western Kentucky, however, faulting is common. characterized at the surface by concentric and radial faults, an uplifted, brecciated, and partly dolomitized described a Precambrian (Keweenawan) rifting event that resulted in formation of the east-continent show the general aspect of this broad uplift and the high-angle fault systems that transect it. For example, less groundwater recharge and increased storm runoff occurs due to increased pavement area. (photo by Edward Nuhfer). Digital Map of the Hayward Fault Map showing active fault traces within the Hayward Fault Zone, including a virtual tour of the Hayward fault in the east San Francisco Bay Region that can be viewed in the Google Earth. strata. The Kentucky Building and Residential Codes (Fig. Hillside road construction can cause earth movements if not properly planned, as shown in the photographs above and below. Cumberland Plateau of Kentucky and Tennessee. The. The zone of radiating faults in far western Kentucky adjacent to the Tertiary strata are part of the Fluorspar District. 5 earthquake lasted approximately 10 minutes. Across a span of millions of years, this gradual, periodic movement can result in thousands of feet of offset along a fault. Kentucky 1:24,000 Geologic Map Data. Contact the BGADD Water Coordinator for more information on Source Water Protection Areas. 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. 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 Lexington Limestone dips on the order of 20 to 30 ft/mi or less away from the apex (Cressman, 1973, p. Buschbach and Atherton (1979) suggest that 0 earthquake. The data in this package is compatible. most movement on faults at the southern end of the Illinois basin took place at the end of the Paleozoic. Rock excavation may be required in areas with shallow soil (excavation was not required here). Output includes the KY county and KY 1:24,000 quadrangle where the coordinate is located and links to map views. Offsets on these fault zones are mostly down to the south. 2 of the geologic map; the Irvine-Paint Creek fault system extends well into sheet 3 as well. 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. 15,000-km2 area there will be on the average one earthquake Of mb about 4 or greater annually. The quakes were so strong the mighty Mississippi River flowed backward for three days. A description of meteor impact sites and other interesting features. from the geologic quadrangle mapping. if (thisYr < 1900) { Let us know if you have suggestions to improve this article (requires login). Surface traces of the faults in the soft alluvium erode quickly or may be rapidly covered by new deposits thereby hiding evidence of earlier earthquakes locations. 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. Other hypotheses attribute faulting to the continued rebound of the crust stemming from the most recent ice age, the buildup of pressure within the Reelfoot Rift zone located in the crustal rocks underground, or the stress brought on by mantle flow changes caused by the descent of the ancient Farallon Plate directly below the region. parts of Illinois, Indiana, and Kentucky and lying between the Ozark uplift on the west and the Cincinnati Cressman (1981) suggested that Mississippian doming over a pre 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. from about 1,500 to about 1,000 m.y. bounded rift zone which is responsible for the relatively high level of modern seismic activity in the New One of the largest earthquakes in North American history happened just west of Hickman, Kentucky, on the Missouri side of the Mississippi River. 0. Some seismologists believe that the maximum magnitude for a quake is 9. 16). Kentucky and adjacent States, indicate that the dominant rock types east of the Grenville Front are granite Rock movement along fault lines might be reactivated during an earthquake. Underlying shale may restrict percolation in some areas. Welcome to the Kentucky Geography Network. 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. A quake of this magnitude would have devastating consequences on infrastructure and could potentially trigger massive tsunamis. (Photographs by Paul Howell, USDA-NRCS. 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. Parts of Kentucky may be profoundly affected by seismicity in the well-known New Madrid seismic zone of A recent seismic study of the crustal section B-B' on sheet I of the geologic map). stratigraphy or sedimentation of the Ordovician rocks that can be related to the arch (Cressman, 1973, p. 8; Paved roads constructed without precautions on swelling soils exhibit heaving, undulation, and extensive cracking. The last one was in 1884. Howell (1963), who applied the name Rome trough to a belt of thickened Cambrian Rome Formation in the Alaska has a long history of powerful earthquakes, including the 1964 Great Alaskan Earthquake which had a magnitude of 9. Where this occurs, minor unmapped faults may be encountered. This new map shows yellow, orange and red lines, which denote differing likelihoods of an earthquake along each fault. labeled on the geologic map, but it appears as a small, round outcrop area of the Muldraugh Member of the Carlisle County - Bardwell. and Kankakee arches on the north and east (fig. 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. This is called a fault. Click the map to show data near to the point you clicked. No, Pine Mountain in Kentucky is not a fault line. Did you know record earthquakes have rocked Kentucky? 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. gneiss, two-feldspar granite, medium-grade metamorphic rock, and anorthosite, while west of the front the geologic map layers are set at 20% transparent by default). Major tectonic events in Kentucky for which evidence has accumulated begin with late Precambrian rifting Pennsylvanian unconformity. Kentucky (fig. The ground shaking that would result could cause buildings to collapse, gas pipelines to rupture, and transportation routes to be blocked. Summaries of the geology in each of Kentucky's counties by Kentucky students. Lexington, Kentucky River, and Irvine-Paint Creek fault systems (fig. This map shows the major fault lines in the US! (Photographs by Paul Howell, USDA-NRCS.). The US Geological Survey estimates that the likelihood of an earthquake with a magnitude of 6 or greater in Kentucky is 0. 16). basin as a whole contains sedimentary rocks of Precambrian to Early Permian age in a sequence that has a Hawaii sits atop the Ring of Fire and experiences around 900 earthquakes each year. The relative direction or motion of movement defines the type of fault. thrust that underlies the structurally complex Middlesboro syncline. may have originated much earlier, however: Schwalb (1969, p. 9) identified a Cambrian-Ordovician basin of Thus, it is still unknown whether or not there has ever been a 10. It was the first major earthquake in California since the 6. Thankfully, there were only minor reported injuries and no deaths associated with the quake. sedimentation, the Reelfoot basin, in roughly the same position, and Cressman (1973, p. 57) interpreted Geophysical 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. Washington experiences frequent, moderate earthquakes from its many active fault systems. However, there is some debate over whether or not there has actually been a 10. These faults were pathways for mineral-rich fluids, which deposited many types of minerals including fluorite. These are discussed in the section on faults. 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. For information on obtaining Kentucky Geological Survey maps and publications call: Public Information Center 859.257.3896. First obvious indications of the arch occurred in However, there is evidence that Kentucky may be experiencing a spike in seismic activity since 2009, with more frequent tremors occurring throughout the state. Earthquakes are rarely felt in Kentucky, and major damaging earthquakes are extremely unlikely. Please refer to the appropriate style manual or other sources if you have any questions. inactive ancient rift zone now recognized in the subsurface there (Hinze and others, 1980). indicating growth faulting with a total throw at the top of the Precambrian of 5,000 ft along the northern zones and some associated with dolomitization (Black and Haney, 1975). Fractured limestone, such as that found in Richmond, can result in leaky reservoirs or embankments. Cross sections C-C' through F-F' on sheet 2 of the geologic map Recent geophysical, geological, and seismological studies of the Reelfoot basin, which underlies the Jackson Boonesboro Quarry mines the Camp Nelson Limestone along the Kentucky River. Silurian deformational event argues against an impact origin. 15). On December 16, 1811, and January 23 and February 7, 1812, a series of three earthquakesthe largest in recorded American history east of the Rocky Mountainsoccurred near the frontier town of New Madrid, Missouri. the Moorman syncline of western Kentucky as the "Eastern Interior Aulacogen" and traced the trough from 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 relatively high seismicity is probably due to resurgent tectonics in the Successful pond construction must prevent water from seeping through structured soils into limestone solution channels below. Denison and others (1984, fig. Several types of smaller, nontectonic faults have also been encountered during mining and are discussed separately in different sections of this website. 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 The Cryptoexplosive structures: J, Jeptha Knob; MO, Middlesboro; MU, Muldraugh dome; V, Versailles.

What states are on the Madrid fault line? Click the section headings to expand or collapse reports. An Equal Opportunity University. 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. Alternate titles: Mississippi Valley fault system, New Madrid Fault. Rough Creek graben, that was active as early as latest Precambrian or earliest Cambrian time and that has document.write(d.getFullYear()); Ordovician) deposition. (epicentre 36.6 N 89.6 W), each measuring greater than magnitude 7.0. What are the most dangerous fault lines in the USA? Atherton (1971, p. 37) suggested that the Kankakee arch, the northwestward extension of the # / ) ) 0 $! 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. 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. Ervin and McGinnis (1975) suggested, largely on the According to the United States Geological Survey, since 1776 there have been around 235 earthquakes that have caused some level of damage in Kentucky. Kentucky). Some Earth scientists suggest that fracturing in this region resulted from stresses brought on by the downcutting of the Mississippi River into the surrounding landscape between 10,000 and 16,000 years ago. 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. Keller (1981) indicate that the Moorman syncline is underlain by a large graben, which they name the to thicken into the Appalachian basin. 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. 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. 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. 877.778.7827 (toll free). 5) also show right lateral offset of about Known Kentucky occurrences: Tectonic faults do not occur everywhere, so faulting is not pervasive. Most polygon layers have some transparency set (e.g. Webb (1969) and Silberman (1972) have interpreted subsurface data as Offset along faults may be measured in inches to thousands of feet. 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. A compacted clay liner, or artificial liner, may prevent pond failure. in western Kentucky (the Rough Creek graben of Soderberg and Keller (1981) and the Mississippi } The Appalachian basin is divided structurally into an eastern highly deformed part, the fold-and-thrust Earthquakes still occur on these faults, but most are so small that they are barely felt. 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. 1979, p. F23) (see cross section G'-G"). ), Swelling soils and expansive clay shales can cause construction problems in some areas of the county. inclusion of the Cumberland thrust sheet of southeasternmost Kentucky in the fold-and-thrust province. %%EOF 0000001314 00000 n While every effort has been made to follow citation style rules, there may be some discrepancies. Contact the Kentucky Division of Water, 14 Reilly Road, Frankfort, KY 40601, telephone: 502-564-3410. The Versailles cryptoexplosive structure was discovered during the cooperative mapping project and has A magnitude Englund and Roen (1963) suggested a meteor-impact origin for the structure on the basis of the presence of probably disappeared during most of the Mississippian and Pennsylvanian (Rice and others, 1979, p. F5, 4 magnitude quake that occurred near the same location on July 4, 2019. It is responsible for several of the fault lines that run through New York City, including one under 125thStreet. subsidence of the Rome trough (Cable and Beardsley, 1984). In some cases, where offset is not too great, mine plans can be altered to ramp (adjust the dip of the excavated entries up or down) across the fault to the level of the coal on the other side of the fault. Pronounced effects of arching are shown by pre-Middle Devonian These fractures can also contribute to roadway failure. It is also known as the Waynesville earthquake, although the epicenter was closer to Skyland. The faults along the southern border of the Western Kentucky Coal Field (part of the Illinois Basin in Kentucky) include the Pennyroyal Fault System. Don't search a large area this way, it takes too long. Rock strata often dip more steeply near faults or between closely spaced faults. Purchase and extends southwestward into Missouri, Arkansas, and Tennessee, suggest that it is a fault 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. Fault gouge is commonly mineralized. Chain-link fencing is used to prevent further rock falls on a road cut in Madison County. and Pakiser, 1982) provides detailed descriptions of historic and modern seismicity and geologic and P, Elliott County peridotite intrusion. 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. 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). Surface faults are well mapped, but unmapped faults or splinter faults branching from mapped faults are sometimes encountered. Fractures in limestone are enhanced by slightly acidic rainwater to produce sinkhole collapses, which are infilled with soil from the surface. 30 mi wide, which coincides with gravity and magnetic highs and extends from south-central Kentucky into The vertical component has been stretched or vertically exaggerated in the above diagram. 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. and especially in western Kentucky. endstream endobj 134 0 obj <>]/PageLabels 122 0 R/Pages 125 0 R/Type/Catalog>> endobj 135 0 obj <>/Font<>>>/Fields[]>> endobj 136 0 obj <>/ProcSet[/PDF/Text/ImageB]/XObject<>>>/Rotate 0/Type/Page>> endobj 137 0 obj <> endobj 138 0 obj <>stream In the block diagram, one can see that the faults continue beneath the Tertiary strata. 12, Geologic Map 1, scale 1:100,000. Without remedial measures, the house will actually become deformed and shatter masonry and windows. The quake was felt widely throughout the state and even as far away as Las Vegas, Nevada. Butler County - Morgantown. subsurface of eastern Kentucky. The quake was the largest earthquake ever recorded in magnitude and intensity, occurring off the coast of Valparaiso, Chile. These structures appear on sheet States located along the Madrid Fault Line include Alabama, Mississippi, Tennessee, and Kentucky. This area, mostly on sheet 3 of the geologic map, forms a part 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. Appalachian basin.--The eastern part of Kentucky, particularly the area east of the Pottsville Escarpment, lies reports indicate that, although the most severe earthquakes (New Madrid type) may occur only every 38) reported wells penetrating brecciated Knox dolomites and cherts below coherent Silurian dolomite, Creek but has fewer and smaller faults; fault scarps along this system exposed by strip mining of the coal In Alabama, the fault line is concentrated in the northeastern part of the state, extending from Cullman County to Lauderdale County. 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 faults that cut across the coal field are part of the Rough Creek FAult System. Kentucky. It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg. 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). migration of an arch through northeastern Kentucky in the Late Cambrian and Early Ordovician; they And there are many more than what you would expect!
