1 on the Richter scale. bifurcates to form the Kankakee and Findlay arches (fig. Kentucky is one of the top ten limestone producers in the country. unexposed Cambrian and Ordovician strata. 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. surveys of the area (Black and others, 1977) show a close relationship between gravity and magnetic data Lexington, Kentucky River, and Irvine-Paint Creek fault systems (fig. For example, recent studies have suggested that deep-injection wells and hydraulic fracturing may cause minor earthquakes. 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). Our editors will review what youve submitted and determine whether to revise the article. The KyGeoNet is the Geospatial Data Clearinghouse for the Commonwealth of Kentucky. Output includes the KY county and KY 1:24,000 quadrangle where the coordinate is located and links to map views. Late Paleozoic (Alleghenian) thrusting in southeasternmost 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. 16). Kentucky Geological Survey. Bullitt County - Shepherdsville. Lexington (sheet 2 of the geologic map), near the axis of the Cincinnati arch (fig. How likely is Kentucky to have an earthquake? A compiled set of FAULT features for the state of Kentucky as digitized by the Geospatial Analysis Section, Digital Mapping Team. 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. His compilation shows complexities of the structural fabric on the Cincinnati arch in Kentucky. The Grenville Front, apparently in Faults are common geologic structures across Kentucky, and have been mapped in many of the Commonwealth's counties. 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. No, earthquakes arent particularly rare in Kentucky. from the Illinois and Michigan basins. 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 septic system is installed for a public facility near Berea. 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. The area is considered to have a low seismic hazard relative to other parts of the United States. Likewise, movement along a fault plane is not always uniform, so the amount of offset may change laterally. reports indicate that, although the most severe earthquakes (New Madrid type) may occur only every The downbow in eastern Kentucky is part of the Appalachian Basin, which extends from Pennsylvania to Alabama. Ervin and McGinnis (1975) suggested, largely on the 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. This is a known . The Mesozoic and Cenozoic were characterized by uplift and minor faulting, associated with This devastating earthquake destroyed numerous homes and took the lives of over 2,000 people. 0000003508 00000 n 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. 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. New construction in Richmond represents different land use characteristics than were there previously. suggest that the Waverly arch represents the position of this migratory arch during Beekmantown (Early The zone of radiating faults in far western Kentucky adjacent to the Tertiary strata are part of the Fluorspar District.

Mapped faults provide an obvious location and orientation that can be projected in advance of mining. The fault zone covers a surface area of 8,846 km2 (3,426 sq. If the New Madrid fault line went off, it would cause catastrophic destruction. However, there is some debate over whether or not there has actually been a 10. Cross sections C-C' through F-F' on sheet 2 of the geologic map Map via USGS 1. All files associated with this page are copyrighted 1997 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. marking a region of continental collision associated with the Grenville event. migration of an arch through northeastern Kentucky in the Late Cambrian and Early Ordovician; they Fault planes are not always vertical, so the position of the fault may change with depth depending on the dip of the fault plane. Keller and others, 1982, p. 220). Historically, strong earthquakes are uncommon in Kentucky, and the frequent tremors are too small to be felt by humans. The Rough Creek fault zone is made up of numerous high Rock excavation may be required in areas with shallow soil (excavation was not required here). Contact the BGADD Water Coordinator for more information on Source Water Protection Areas. Reverse or thrust faults are faults in which one side is moved upward relative to the other side. A recently assembled series of studies on the New Madrid region (McKeown Cable and Beardsley (1984) have traced the westward 141 0 obj <>stream 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. Use the search capabilities of the KyGovMaps Open GIS Data . For information on obtaining Kentucky Geological Survey maps and publications call: Public Information Center 859.257.3896. Ponds with dam heights exceeding 25 feet, or pond volumes exceeding 50 acre-feet require permits. Harris (1970) has shown the fault to be a ramp on a bedding plane startxref The Kentucky Building and Residential Codes (Fig. In the fall of 1996, ESEN was expanded to provide resources from around the globe using the World Wide Web. Geophysical studies by Soderberg and 16), resulting in the Black (1978) has compiled structure contours for central Kentucky from the geologic quadrangle maps. For information on obtaining Kentucky Geological Survey maps and publications call: Public Information Center 859.257.3896. Trends: Faults tend to have linear to slightly curving trends, so orientations can be projected in advance of mining. 0 In areas overlying limestone, septic system leaks can occur through fractures in the limestone, contaminating groundwater. gneiss, two-feldspar granite, medium-grade metamorphic rock, and anorthosite, while west of the front basin as a whole contains sedimentary rocks of Precambrian to Early Permian age in a sequence that has a The faults that cut across the coal field are part of the Rough Creek FAult System. 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. Don't search a large area this way, it takes too long. 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). Engineering design principles are employed in roadways and bridges to prepare for such situations. Remedies vary from mere maintenance that keeps drainage away from the house to expensive reconstruction of foundations. Yes, Kentucky is in a seismic zone. 5) also show right lateral offset of about 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. 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. Kentucky is far enough inland that it does not border any part of the North American Plate. Overall, the Madrid Fault Line affects the following states: Alabama, Mississippi, Tennessee, and Kentucky. Illinois basin.--The Illinois basin is a major structural downwarp in the eastern midcontinent, occupying large Fault gouge is commonly mineralized. The nature of the Precambrian basement is not well known. Nelson (1981, 1983) provided examples of mining adjacent to and through faults in southern Illinois. amphibolites, and mafic granulites are found in the vicinity of highs. response to some later event, formed along the western margin of the gravity high (Lidiak and Zeitz, 1976; 11) and continue mining. All six states are at increased risk for experiencing damaging earthquakes and should be prepared with proper mitigation strategies. The Jessamine dome (fig. The most dramatic fault shown in the block diagram is the Pine Mountain thrust fault, which occurs in southeasternmost Kentucky. The age is closely constrained: disturbed beds include geophysical features of the region that may be useful in understanding the nature of the seismicity. (1983, p. 24). 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. Creek but has fewer and smaller faults; fault scarps along this system exposed by strip mining of the coal The following brief descriptions of the four structural provinces include discussions of their regional setting, The threat is so great, the BBC even did a nifty video on the potential MegaQuake threat. Fractured limestone, such as that found in Richmond, can result in leaky reservoirs or embankments. Thousands of milder aftershocks occurred daily for more than a year. mi. Originally, the network provided a group of geologists who served as resource persons for teachers. Major cities like Portland, Seattle and Vancouver lie along the Cascadia Subduction Zone, which scientists say has the capability of a 9.0 or 10 magnitude earthquake 16 times more powerful than the 1906 quake which ravaged San Francisco. Seismic risk associated with these faults is very low. The Appalachian basin is divided structurally into an eastern highly deformed part, the fold-and-thrust 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. 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. . The Illinois-Kentucky fluorspar district, at the west end of the Moorman syncline, is a structurally complex gentle dome culminates near the intersection of the Lexington and Kentucky River fault systems (fig. Create a bookmark, record the ID, and use your own layout here. subsidence of the Rome trough (Cable and Beardsley, 1984). 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. field (sheet I of the geologic map). Although the arch was a positive structural element through much of the Paleozoic, strata were probably disappeared during most of the Mississippian and Pennsylvanian (Rice and others, 1979, p. F5, California experiences thousands of earthquakes each year, many of which cause moderate to significant damage. 30 mi wide, which coincides with gravity and magnetic highs and extends from south-central Kentucky into A compacted clay liner, or artificial liner, may prevent pond failure. Kentucky was succeeded by intrusion of ultramafic dikes (western Kentucky) and diatremes (eastern Earthquakes that occur in the zone can have a significant impact on the region, primarily due to the regions large population and aging infrastructure. 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. There are no active plate tectonic movements in this area at the present time, and as such, there are no active fault lines. Of the three by the Kentucky Geological Survey, The vertical component has been stretched or vertically exaggerated in the above diagram. Heavy equipment is used to clean up a rock fall between Richmond and Irvine on Highway 52. lineament, defined by aeromagnetic and gravity data, which lies across the easternmost tip of Kentucky; northeastern Kentucky (Dever and others, 1977). 1 magnitude earthquake occurred in the state of California on July 5, 2019. Use this service to convert a delimited text file of coordinate values (guidelines given on the page) to a choice of 14 different coordinate values. 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. 0000001314 00000 n dome (Lexington dome of some authors), a culmination of the arch in central Kentucky; the Cumberland According to the United States Geological Survey, since 1776 there have been around 235 earthquakes that have caused some level of damage in Kentucky. Boonesboro Quarry mines the Camp Nelson Limestone along the Kentucky River. Click the section headings to expand or collapse reports. These 198 earthquakes in the past 365 days. FIGURE 17.-Index to location of cross sections on the geologic map. Below the sedimentary rocks are igneous and metamorphic rocks. 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. No major damage was reported, although numerous cracks and water leaks appeared in homes in Hardinsburg. The origin of the Muldraugh dome is uncertain. The relatively high seismicity is probably due to resurgent tectonics in the 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. Underlying shale may restrict percolation in some areas.

Caldwell County - Princeton. Most polygon layers have some transparency set (e.g. 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. Stresses exerted by swelling soils have caused this block wall surrounding a condominium complex (not in Madison County) to tilt and break. 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. What are gas prices at Buc EEs in Richmond KY? Throughout the county ground water is hard or very hard and may contain salt or hydrogen sulfide, especially at depths greater than 100 feet. The Irvine-Paint Creek fault system extends eastward from central Computer Simulation of a Magnitude 7.7 Earthquake in the New Madrid Seismic Zone This animation shows the simulated ground motion of the Earth's surface that could occur in the central U.S. region for a magnitude 7.7 strike-slip earthquake on the southern section of the New Madrid seismic zone. Valley syncline (Krause and Treworgy, 1979). Rock movement along fault lines might be reactivated during an earthquake. 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. document.write(d.getFullYear()); From AIPG (1993).

What is the Jane Austen Society of North America. . Seismologists say we can expect the next one any day now. Fun times! KGS Home > Geology of Kentucky from the geologic quadrangle mapping. Alternate titles: Mississippi Valley fault system, New Madrid Fault. Webb (1969) and Silberman (1972) have interpreted subsurface data as In Mississippi, the fault line passes through the following counties: Tishomingo, Itawamba, Pontotoc, Prentiss, as well as part of Tippah and Alcorn counties. Lying in the central area of the North American Plate, the seismic zone is about 45 miles (70 km) wide and about 125 miles (200 km) long. Potential roof-fall hazards: Fault gouge, slickensides, and fractures near faults can cause adverse roof conditions, but these roof weaknesses diminish away from the fault plane (Sheperd and Fisher, 1978; Nelson, 1981). 877.778.7827 . Embayment) and in central Kentucky (Keller and others, 1982). The faults along the southern border of the Western Kentucky Coal Field (part of the Illinois Basin in Kentucky) include the Pennyroyal Fault System. The 5 earthquake lasted approximately 10 minutes. It was the largest tremor felt in the state since 2003. Quadrangle 5 earthquake, the resulting tsunami impacted countries thousands of miles away, devastating communities and taking even more lives. The quake was felt for over 200,000 square miles, including in the Carolinas, Alabama, Kentucky, and West Virginia. 70 mi on the Grenville Front at the Kentucky River fault system and a north-trending basaltic rift zone some 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. 16). thisYr = thisYr + 1900; 02% in any given year. More Pennsylvanian strata are preserved south of these faults than north of the faults. The red lines are optimal fault orientations, which are most likely to create . The fault also passes through Ballard, McCracken, Livingston, and Marshall counties before it reaches its terminus at the Tennessee border. bounded rift zone which is responsible for the relatively high level of modern seismic activity in the New 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. 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. saddle, the depression between the Jessamine dome and the Nashville dome of Tennessee; and the The first shock was felt from Canada to New Orleans and as far away as Boston, Massachusetts and Washington, D.C. Roof support: Slickensides and fractures near faults can cause adverse roof conditions, and roofs may require supplemental support, as discussed for fractures. may have originated much earlier, however: Schwalb (1969, p. 9) identified a Cambrian-Ordovician basin of Dams should be constructed of compacted clayey soils at slopes flatter than 3 units horizontal to 1 unit vertical. the geologic map layers are set at 20% transparent by default). The New Madrid earthquake series of 1811-12 produced the strongest shocks known to have been felt in Appalachian basin.--The eastern part of Kentucky, particularly the area east of the Pottsville Escarpment, lies The origin of the Jeptha Knob structure is uncertain, but meteoroid impact seems most likely 0000003418 00000 n Definition and formation: Faults are breaks in the earths crust across which movement has occurred. The arch continued Cincinnati arch (fig. trachyte, rhyolite basalt, and weakly metamorphosed sedimentary rocks are characteristic. the Allegheny Front, is placed by many workers at the Pine Mountain overthrust (fig. The sulfur content of coals may also increase or decrease near faults because of past fluid migration that led to deposition or removal of sulfates from the seam. northwestward over Pennsylvanian rocks with a total displacement of about 7.5 mi (Rice, Sable, and others, Note that most faults that can affect residents are either onshore or just offshore. Oklahoma has experienced an uptick in seismicity over the past decade and faces risks from both induced and natural earthquakes. Its not just the Virginia Seismic Zone New Yorkers have to worry about. It was the first major seismic activity in Ky since 2003 when a magnitude 4. 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. in western Kentucky (the Rough Creek graben of Soderberg and Keller (1981) and the Mississippi The GFZ runs north-south through central Kentucky, stretching from near Louisville eastward to the Appalachian foothills. 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. 16; not labeled on the geologic map) occupies most of central Kentucky, as If oil, gas (methane), and water enter the mine along faults, these can obviously hinder mining and be safety concerns. 16). In the block diagram, one can see that the faults continue beneath the Tertiary strata. by a brecciated center within a belt of concentric faults. recurrence curve plotted for the New Madrid seismic zone (Nuttli, 1979) shows that, for example, in a 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. The broad, (photo by Edward Nuhfer). xref Both sides of the Illinois Basin are preserved in western Kentucky, which is why the Pennsylvanian strata on the geologic map have a roughly circular pattern surrounded by Mississippian strata. 2 and caused major destruction throughout the state. A recent seismic study of the crustal The quake occurred at 8:59 am local time and was felt from Jackson to the west, into Indiana and further east to Berea. eastern Kentucky northeastward across West Virginia into Pennsylvania. These fractures can also contribute to roadway failure. Beneath the Surface [Geologic Structures]. 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. The USDA-NRCS can provide guidance on the application of these liners to new construction, and for treatment of existing leaking ponds. Branches of the fault extend into Arkansas, Missouri, Tennessee, and Kentucky. 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. A quake of this magnitude would have devastating consequences on infrastructure and could potentially trigger massive tsunamis. does not extend westward of the Lexington fault zone. 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. Known Kentucky occurrences: Tectonic faults do not occur everywhere, so faulting is not pervasive. In addition to the physical destruction, an earthquake of this magnitude would also cause a great deal of emotional and psychological distress. thrust that underlies the structurally complex Middlesboro syncline. Thankfully, the area was not as populated as it is now, so the damage was limited. Please refer to the appropriate style manual or other sources if you have any questions. 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. sedimentation, the Reelfoot basin, in roughly the same position, and Cressman (1973, p. 57) interpreted The general configuration of the basin is shown by a contour map of the base of the All of these fault lines have the potential to produce earthquake activity, though the greatest threat is to the NMFZ. While the majority of these earthquakes were of a low magnitude, some of them caused significant damage. Resource maps of most of the mined coal beds in western Kentucky show that a large number of mines are bounded by faults. and the structure as mapped at the surface. A magnitude Appropriate preparation is needed when approaching faults underground, in case fluids or gases are encountered. Rough Creek fault system through at least Early Permian time. Most of the movement along Kentucky's faults occurred in the distant past. been described by Black (1964). King and Zeitz (1978) have recognized the New York-Alabama basement 9) coal (Greb and Williams, 2000). Offsets on these fault zones are mostly down to the south. While every effort has been made to follow citation style rules, there may be some discrepancies. 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. ), and was discovered in the late 1960s. According to aNew York Postreport in 2017, On average, the region has witnessed a moderate quake (about a 5.0 on the Richter scale) every hundred years. 8, with anything past that not being measureable or happening at all. F21). Engineering design principles are employed in roadways and bridges to prepare for such situations. Cincinnati arch.--The Cincinnati arch, a prominent regional uplift in the eastern midcontinent, extends from One of the largest earthquakes in North American history happened just west of Hickman, Kentucky, on the Missouri side of the Mississippi River. Thanks for contacting us. The Kentucky River fault system has been extended eastward, %%EOF was a shoal in late Middle and early Late Ordovician time.
