Overall, the Madrid Fault Line affects the following states: Alabama, Mississippi, Tennessee, and Kentucky. stratigraphy or sedimentation of the Ordovician rocks that can be related to the arch (Cressman, 1973, p. 8; A septic system is installed for a public facility near Berea. initiation of the Illinois and Appalachian basins. The arch thus separates the Appalachian basin 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. Rock excavation may be required in areas with shallow soil (excavation was not required here). Soderberg and Keller (1981) suggest that it is underlain by a deep-seated graben of late Precambrian age, show the general aspect of this broad uplift and the high-angle fault systems that transect it. 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. 16). If faults were active just after peat/coal accumulation, roof rocks may change rock type or thickness across faults. was a shoal in late Middle and early Late Ordovician time. Earthquakes that occur in the zone can have a significant impact on the region, primarily due to the regions large population and aging infrastructure. Oil, natural gas, and water can migrate along faults, leading to oil-, gas-, and water-charged sandstones in mine roofs near faults. These structures appear on sheet Prior site planning that takes geology into account is always preferable to dealing with problems after a structure is built. Kentucky). 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. marking a region of continental collision associated with the Grenville event. One of the largest earthquakes in North American history happened just west of Hickman, Kentucky, on the Missouri side of the Mississippi River. The NMSZ is the most active seismic area in the United States east of the Rocky Mountains. The Pennyrile fault system (Green River fault zone of Lidiak 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. 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. They write new content and verify and edit content received from contributors. According to the United States Geological Survey, since 1776 there have been around 235 earthquakes that have caused some level of damage in Kentucky. upwarping in the Early to Middle Devonian, and again during formation of the regional Mississippian The faults along the southern border of the Western Kentucky Coal Field (part of the Illinois Basin in Kentucky) include the Pennyroyal Fault System. Ponds with dam heights exceeding 25 feet, or pond volumes exceeding 50 acre-feet require permits. Rough Creek fault system through at least Early Permian time. Throughout the county ground water is hard or very hard and may contain salt or hydrogen sulfide, especially at depths greater than 100 feet. 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. 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. 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. It was the first major earthquake in California since the 6. 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. 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. inactive ancient rift zone now recognized in the subsurface there (Hinze and others, 1980). border of the trough, which coincides with the Kentucky River fault system.

The Grenville Front, apparently in It is a domal structure, about 2 mi in diameter and unfaulted Ordovician) deposition. Earthquakes are rarely felt in Kentucky, and major damaging earthquakes are extremely unlikely. The age is closely constrained: disturbed beds include The quakes were so strong the mighty Mississippi River flowed backward for three days. 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. . Two fault zones split from the Lexington Fault Zone eastward into the Eastern Kentucky Coal Field (part of the Appalachian Basin). Pennsylvanian system compiled by Coskren and Rice (1979) from data derived from drilling records and unexposed Cambrian and Ordovician strata. Irvine-Paint Creek fault systems, the Pine Mountain thrust fault, and the Waverly arch of northeastern parts of Illinois, Indiana, and Kentucky and lying between the Ozark uplift on the west and the Cincinnati Cable and Beardsley (1984) have traced the westward 0000000879 00000 n 5 earthquake, the resulting tsunami impacted countries thousands of miles away, devastating communities and taking even more lives. The most recent major earthquake in Ky was the M4. 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. Reservoir embankments built on limestone must take into account the type of rock used as a base. Pennsylvanian unconformity. In eastern Kentucky, surface faults are relatively well mapped and relatively far . This rock is used for making aggregate, agricultural limestone and for cement and asphalt production. Most of the movement along Kentucky's faults occurred in the distant past. Welcome to the Kentucky Geography Network. The Mesozoic and Cenozoic were characterized by uplift and minor faulting, associated with 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. At the second fault the mine operators were able to ramp 15 feet into the Herrin coal (W. Ky. No. The origin of the Muldraugh dome is uncertain. Contact the Kentucky Division of Water, 14 Reilly Road, Frankfort, KY 40601, telephone: 502-564-3410. 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. lineament, defined by aeromagnetic and gravity data, which lies across the easternmost tip of Kentucky; Pronounced effects of arching are shown by pre-Middle Devonian 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. At the surface it is represented What are the most dangerous fault lines in the USA? Of the three 2 and caused major destruction throughout the state. Most polygon layers have some transparency set (e.g. The following brief descriptions of the four structural provinces include discussions of their regional setting, While the majority of these earthquakes were of a low magnitude, some of them caused significant damage. FIGURE 17.-Index to location of cross sections on the geologic map. 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). Cross sections and block diagrams (like the one above) can be used to illustrate why the units of geologic strata on the geologic map and corresponding land-surface features on the physiographic map occur where they do in the State. Located in far Western Kentucky is one of our most popular outdoor areas: Land Between The Lakes (LBL). What states are on the Madrid fault line? Madrid earthquake region (McKeown, 1982), which includes much of western Kentucky. displacement, down to the south, generally of about 300 ft but locally as much as ten times that (see cross It has produced magnitude 8 to 8.

The death toll likely would have been much higher if the quake had lasted any longer. 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. Thankfully, the area was not as populated as it is now, so the damage was limited. Yes, Kentucky is in a seismic zone. labeled on the geologic map, but it appears as a small, round outcrop area of the Muldraugh Member of the The time of formation of the Cincinnati arch in central Kentucky has recently been discussed by McDowell 133 9 4 magnitude quake that occurred near the same location on July 4, 2019. and Zietz, 1976), marking the southern boundary of the Moorman syncline, is similar in form to the Rough characterized at the surface by concentric and radial faults, an uplifted, brecciated, and partly dolomitized Some wells in this area drilled along drainage lines that may produce enough water for a domestic supply except during dry weather. section B-B' on sheet I of the geologic map). In some cases, coals become mineralized (calcite veins, etc.) The 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. Click the section headings to expand or collapse reports. 0000001550 00000 n The Kentucky Geological Survey states that there are four major fault lines that run through Kentucky: the New Madrid Fault Zone (NMFZ), Greenville Fault Zone (GFZ), Easterville Fault Zone (EFZ), and Cherokee Uplift (CU). The Illinois-Kentucky fluorspar district, at the west end of the Moorman syncline, is a structurally complex 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. var d = new Date(); geophysical features of the region that may be useful in understanding the nature of the seismicity. include the Michigan basin as well. Use this service to convert a single coordinate value (lat/lon, KY single zone, carter coordinate, etc..) to 14 different coordinate values. Geophysical and the structure as mapped at the surface. sheet I of the geologic map). Therefore, the term "Illinois basin" is used herein to avoid confusion.) 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. 0000001185 00000 n For example, less groundwater recharge and increased storm runoff occurs due to increased pavement area. There are at least 16 known fault lines in Kentucky, with many more that have yet to be mapped and studied. considerably more data, report a close correlation between gravity anomalies and basement lithology: Cincinnati arch (fig. 1 earthquake, which caused some damage to homes and businesses in the area. Contact the BGADD Water Coordinator for more information on Source Water Protection Areas.

While every effort has been made to follow citation style rules, there may be some discrepancies. 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. Butler County - Morgantown. What would happen if the New Madrid fault line went off? Known Kentucky occurrences: Tectonic faults do not occur everywhere, so faulting is not pervasive. Legend Issues: Some legend items may not print in the layout. Ordovician inception of the arch in Kentucky, the geologic quadrangle mapping has shown no features of 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. Although the arch was a positive structural element through much of the Paleozoic, strata were Seismologists say we can expect the next one any day now. Fun times! The. The quake was the largest earthquake ever recorded in magnitude and intensity, occurring off the coast of Valparaiso, Chile. Valley syncline (Krause and Treworgy, 1979). Successful pond construction must prevent water from seeping through structured soils into limestone solution channels below. the presence of an ancestral Mississippi Embayment. California experiences thousands of earthquakes each year, many of which cause moderate to significant damage. may have originated much earlier, however: Schwalb (1969, p. 9) identified a Cambrian-Ordovician basin of Paved roads constructed without precautions on swelling soils exhibit heaving, undulation, and extensive cracking. 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 Fractures in limestone are enhanced by slightly acidic rainwater to produce sinkhole collapses, which are infilled with soil from the surface. Kentucky to a terminus near Paintsville (sheet 3 of the geologic map); the southern block is displaced Rock movement along fault lines might be reactivated during an earthquake. We obtained all three digitized sets of fault locations. The origin of the Jeptha Knob structure is uncertain, but meteoroid impact seems most likely probably disappeared during most of the Mississippian and Pennsylvanian (Rice and others, 1979, p. F5, downward as much as 200 ft. 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. First obvious indications of the arch occurred in 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). 5 earthquake lasted approximately 10 minutes. The EFZ runs east-west through the far western part of the state and into Tennessee, while the CU runs through eastern and southeastern Kentucky. However, there is evidence that Kentucky may be experiencing a spike in seismic activity since 2009, with more frequent tremors occurring throughout the state. 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 broad, Late Paleozoic (Alleghenian) thrusting in southeasternmost Creek and Pennyrile fault systems, the Moorman syncline, and faults in and around the Illinois-Kentucky Cryptoexplosive structures: J, Jeptha Knob; MO, Middlesboro; MU, Muldraugh dome; V, Versailles. Other leakage prevention measures include synthetic liners, bentonite, and asphaltic emulsions. and Kankakee arches on the north and east (fig. From AIPG (1993). exposed and subjected to erosion only briefly at the end of the Ordovician, during the period of intensive (epicentre 36.6 N 89.6 W), each measuring greater than magnitude 7.0. The quake was felt across much of the state and many neighboring states. McGuire and Howell (1963, p. 2-4) presented This map courtesy of the U.S. Geological Survey (USGS) shows the major earthquake hazard areas within the United States based on fault lines. The Kentucky Building and Residential Codes (Fig. to thicken into the Appalachian basin. gravity high, which passes north-south through east-central Kentucky. Contains faults, geologic units, and geologic contacts. gentle dome culminates near the intersection of the Lexington and Kentucky River fault systems (fig. described a Precambrian (Keweenawan) rifting event that resulted in formation of the east-continent Without remedial measures, the house will actually become deformed and shatter masonry and windows. In addition, Keller and others (1982) It is responsible for several of the fault lines that run through New York City, including one under 125thStreet. 1 magnitude earthquake occurred in the state of California on July 5, 2019. 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.

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. KGS Home > Geology of Kentucky Old mine maps in a potential mine area can also provide information as to the location of potential faults. 198 earthquakes in the past 365 days. Major tectonic events in Kentucky for which evidence has accumulated begin with late Precambrian rifting place of about 35,000 ft (Colton, 1970, p. 13). suggest that the Waverly arch represents the position of this migratory arch during Beekmantown (Early 3 quake occurred near Smiths Grove. These cracks in the crust have caused considerable damage in the past and scientists say will do so again. A magnitude composite thickness for the entire basin of at least 63,000 ft but reaches a maximum thickness in any one Resource maps of most of the mined coal beds in western Kentucky show that a large number of mines are bounded by faults. from the geologic quadrangle mapping. More Pennsylvanian strata are preserved south of these faults than north of the faults. surveys of the area (Black and others, 1977) show a close relationship between gravity and magnetic data Offset along faults may be measured in inches to thousands of feet. King and Zeitz (1978) have recognized the New York-Alabama basement been reactivated in the late Paleozoic and possibly Mesozoic. Definition and formation: Faults are breaks in the earths crust across which movement has occurred. 38) reported wells penetrating brecciated Knox dolomites and cherts below coherent Silurian dolomite, 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. 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. Carter County - Grayson. thisYr = now.getYear(); The largest earthquake in recorded history to have ever occurred in Kentucky was a magnitude 5. This structure is not The faults shown on the Madison County map represent seismic activity that occurred several million years ago at the latest. Quadrangle The New Madrid earthquakes of the winter of 1811-1812 were the largest in the history of the United States. The general configuration of the basin is shown by a contour map of the base of the Normal faults are faults in which one side of the earths crust is offset downward relative to the other side. [Click on image to see a larger version in a new window. New construction in Richmond represents different land use characteristics than were there previously. 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. P, Elliott County peridotite intrusion. Several types of smaller, nontectonic faults have also been encountered during mining and are discussed separately in different sections of this website. 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. USGS Interactive Fault Maps. This 150 mile-long series of faults stretches under five states: Illinois, Missouri, Arkansas, Tennessee and Kentucky, and is responsible for four of the largest earthquakes in the history of. Yes, there have been 10. Embayment across a gentle, northwest-trending arch (Heyl and others, 1965; Pinckney, 1976; Trace and Click the map to show data near to the point you clicked. 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. University of Kentucky. Denison and others (1984), in a report on basement rock types and age in Atherton (1971, p. 37) suggested that the Kankakee arch, the northwestward extension of the from about 1,500 to about 1,000 m.y. From AIPG (1993). The fractures are covered by thick layers of rock, which in turn are . The Rough Creek fault system (Rough Creek-Shawneetown of some authors) crosses the southern end of The fault line, located in the Midwest region of the United States, is responsible for a higher risk of damaging earthquakes. area dominated by numerous closely spaced high-angle faults trending northeastward from the Mississippi HTML. gneiss, two-feldspar granite, medium-grade metamorphic rock, and anorthosite, while west of the front if (thisYr < 1900) { structure of the embayment by Austin and Keller (1982) is consistent with this model. Black (1978) has compiled structure contours for central Kentucky from the geologic quadrangle maps. Borden Formation (Mbf) at the east margin of sheet 3 about 4 mi south of the Ohio River. 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. Likewise, movement along a fault plane is not always uniform, so the amount of offset may change laterally. the Illinois basin in Kentucky and forms the northern boundary of the east-west-trending Moorman These are discussed in the section on faults. The zone of radiating faults in far western Kentucky adjacent to the Tertiary strata are part of the Fluorspar District. 16). 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. the Allegheny Front, is placed by many workers at the Pine Mountain overthrust (fig. Remedies vary from mere maintenance that keeps drainage away from the house to expensive reconstruction of foundations. Cressman (1981) suggested that Mississippian doming over a pre These fault lines are all part of the larger New Madrid Seismic Zone, a region spanning 7 states and known for its earthquake activity. 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. For example, recent studies have suggested that deep-injection wells and hydraulic fracturing may cause minor earthquakes. 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). 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. Keller and others, 1982, p. 220). Cross sections C-C' through F-F' on sheet 2 of the geologic map The town of Middlesboro, in far southeastern Kentucky (sheet 3), is located in a topographic basin that is the inclusion of the Cumberland thrust sheet of southeasternmost Kentucky in the fold-and-thrust province. ], [Click on image to see a larger version in a new window.].
