[9] It dips first northeastward[12] but deeper it becomes either vertical or down-to-the-southwest,[13] but certainly steep at depth. [17] It is possible that the fault rupture was limited by geological structures that occur at the northwestern end of the Meers fault[45] where it splays out. Initially, I was unsure whether to make this into a How to for the Fault Line map or have it as a ship video. $37.99 . Merriam (1955c) found that in eight of ten fields in central and western Kansas the structural relief on the Stone Corral is less than on t… [16], A conspicuous[17] 5-meter (16 ft) high and 26-kilometer (16 mi)[18]–22-kilometer (14 mi) long fault scarp just north of the Wichita Mountains is noticeable on Google Earth;[17] it has formed on the Holocene part of the fault[18] and continues southeastwards in the form of more subtle scarps[12] although it may not exactly coincide with the path of the fault. 128). Wichita Blue City Flag State Short Sleeve T Shirt . Line of section shown in Figure 5. [19] Because the scarp is not present along the entire length of the fault, it is subdivided in a southeastern section in Comanche County and a northwestern section in Kiowa County, with only the southeastern section featuring a scarp. [30] The development of the Meers fault may have been influenced by the South Oklahoma aulacogen. [56] Likewise, seismicity is scarce in the wider region[31] and photographic analysis has shown little evidence of recent fault movement in other faults of the Wichita fault system. [64], The fault was discovered during field work in the 1930s[68]–1940s[39] and is named after the town of Meers; previously it was known as the "Thomas fault"[21] after a ranch named George Thomas Ranch[69] and then as the "Meers Valley fault". There are 565 earthquake incidents in Kansas on record since 1931. All rights reserved. The county does run over a fault line. The Meers Fault runs along the northern side of Meers Valley[1] through Comanche County and Kiowa County and close to Caddo County[2] in an east-southeast to north-northwest direction. [17] The scarp was described as a Permian fault scarp before Holocene activity was discovered[70] and made known by Gilbert 1983 and Donovan et al. [61], Judging earthquake hazards in the central and eastern United States is made hard by the scarcity of geological evidence of seismicity, the long timespans between earthquakes and the shortness of the historical record thereof. [58] The discovery of Holocene activity at the Meers fault was a surprise to scientists[71] and attracted the attention of geologists[72] after two publications in 1983 highlighted the young movements on this fault;[17] it is the best researched fault east of Colorado. He said it’s not unheard of for there to be earthquakes in northeast Wichita. “You … Wichita Humboldt-fault. [51] In general, the movement direction of the Meers fault is contentious. It cuts off the Meers fault. The earthquake shook the city just after 5 a.m. Wednesday morning. [21] Other faults in the area are the Blue Creek Canyon fault which is connected to the Meers fault at its northwestern end, the Broxton Fault Complex northeast and the Mountain View fault to the north[3] which intersects with[32] and is also connected to the Meers fault. [31], The Meers fault is among the most prominent tectonic structures in the region. United States", https://www.researchgate.net/publication/236473980_Investigation_of_the_Meers_fault_in_southwestern_Oklahoma, 10.1130/0016-7606(1990)102<0001:SATOHS>2.3.CO;2, "The Meers Fault: tectonic activity in southwestern Oklahoma. Looking at … [12], Two to four earthquakes occurred during the Holocene in the last 6,000 years,[17] one of which occurred 1,100–1,300 years ago and the other 2,000–2,900 years ago. For Miller, seeing earthquakes happening there again made sense. Wichita Navy Workhorse Long Sleeve Light Weight Hood . [65] Other regional faults such as the Washita Valley fault which runs parallel to the Meers fault may also be capable of causing earthquakes. There isn’t an active enough fault-line to produce the […] RENO COUNTY, Kan. — Earthquakes keep rocking Kansas this year. WICHITA, Kan. — the major basin-bounding fault, dips 20-30o SW beneath the Slick Hills and Wichita Mountains. The KCC released the following statement. Synopsis General: Fault originally mapped in about the late 1930s, and scarp was considered to be an erosionally exhumed fault-line scarp. [18] In addition, earthquakes are often only weakly correlated to geological structures such as faults. He showed a map with two possible other faults not connected to the Humboldt fault line. Wichita Womens Red Fault Line Jr Tank Top . $27.99 . Nine … Wichita Womens Red Fault Line Jr Tank Top . The interval Pennsylvanian Hogshooter - top Mississippian “lime” is about 840 feet thicker in the two fault blocks comprising the graben than in the areas to the west and to the east. Wichita 3x5 Red Silk Screen Grommet Flag . $27.99 . [14] One interpretation is that the Meers fault is a "back-thrust" that dips northwards. Just for some info to those who may not know, Wichita and most of the Eastern side of Kansas running from north to south sits atop the Humboldt Fault Line as … [9] Finally ductile folding,[25] vegetation and landform variations have also been recognized on the Meers fault. Dr. Rick Miller with KGS didn’t give a specific cause for the earthquake but noted the city does sit on a fault line, making earthquakes common. [3] The nature of the surrounding rocks also influences the expression of the Meers fault, as it has a more pronounced scarp in erosion-resistant rock units. It is marked by a 22–26 kilometers (14–16 mi) long conspicuous fault scarp but the fault extends beyond the ends of this scarp. [14] The fault may generate strong earthquakes in the future;[66] earthquakes with magnitudes Mw 7.5–8 might be possible on the Meers fault[67] and an earthquake similar to the Holocene ones would be felt over large parts of the continent, including Oklahoma and Texas,[54] with intensities comparable to these of the 1886 Charleston earthquake and 1811–12 New Madrid earthquakes. Wichita Grey City Flag Short Sleeve T Shirt . He said it’s not unheard of for there to be earthquakes in northeast Wichita. Structural cross-section across the Garber graben. Looking at possible causes of the numerous earthquakes reported in the area since Thanksgiving, a local geologist explains why he thinks there is a newly-identified fault line. Regional subsurface mapping, seismic data, and outcrop observations indicate that the Wichita Mountains have been thrust over the Slick Hills by a fault named here as the Wichita Mountains fault (Figure 5-9) . The state averages 7 earthquakes per year. Year Published: 1978 Preliminary map of young faults in the United States as a guide to possible fault activity. He said it’s not unheard of for there to be earthquakes in northeast Wichita. WICHITA, Kan. (KWCH) - The Kansas Geological Survey reported a magnitude 3.9 earthquake in Wichita. It may exist. “But I would rather not live in a tectonically active zone.”. In general, it may be stated that the amount of closure increases with depth. 130) to 104 feet at Coats (Fig. The Mississippi embayment is a broad trough filled with marine sedimentary rocks about 50-100 millions years old and river sediments less than 5 millions years old. Geologist explains possible cause of Wichita earthquakes, Evergy concludes emergency shutoffs, could do more in days ahead, Evergy alerts of potential blackouts, urges consumers to reduce electricity use, Gov. WICHITA, Kan. (KWCH) - The latest earthquake registered in east Wichita was felt early Monday morning and measured at a magnitude of 2.2. $19.99 . © Provided by Wichita-Hutchinson Plus KWCH-DT Two unidentified fault lines in east Wichita could be the source of recent earthquakes in the area, a retired geology professor believes. WICHITA, Kan. (KWCH) - The latest earthquake registered in east Wichita was felt early Monday morning and measured at a magnitude of 2.2. [34] The fault system, which also includes the Meers fault[35] as its southern margin,[36] was active during the Mississippian to Permian, generating a total offset of about 12 kilometers (7.5 mi). But, quakes on it are super rare and we are voted as one of the least 5 states to have earthquakes. I googled it and I guess there is a fault line that runs southwest out of Nebraska and though Kansas. [62] Assessing the hazard potential for the Meers fault suffers from similar problems[44] but it is considered the largest seismic hazard source of the central United States[63] as it has the potential to cause large earthquakes[31] and earthquakes in the central United States usually affect much larger regions than those of the western United States. ", "My Favorite Outcrop(s): An Imposter Exposed? However, Pleistocene sediments and Holocene alluvium have been offset, indicating fault movement during this time. The overwhelming majority of earthquakes are caused by natural phenomena and tension building up between tectonic plates and along fault lines. Wichita Olive Green Wordmark Keeper Short Sleeve T Shirt . The ones I’ve felt in Wichita in the past have normally lasted several seconds like a low rumble these jolts are freaky. [35], Reconstructions of the intensity of the Holocene earthquakes indicates magnitudes of Mw 6.75–7.25[18] with possibly similar intensities,[48] with the terrain north of the fault being shifted upwards and leftwards relative to the terrain to its south;[18] this latter movement[35] and the position of the Meers fault are consistent with the tectonic stress pattern of North America[7] which favours movement along the Meers fault. [15] Unlike many other faults, there is no evidence of segmentation in the Meers fault. [12] Both the Wichita Mountains thrust[17] and possibly a second fault are linked with the Meers fault,[37] which is the only fault in the Wichita fault system with Holocene activity. I don’t know if they will or won’t,” Dr. Mazzullo said. [54], The USGS national hazard map states that the Meers fault has a recurrence interval of 4,500 years[44] but estimates range from 100,000 years to 1,300 years. Dr. Mazzullo believes there are new, previously unrecognized faults under Wichita. [13] The erosion/sedimentation patterns[22][23] and the path of drainages[10] such as Canyon Creek may have been influenced by movement along the fault,[24] and topographic ridges are offset. A possible fourth and fifth quakes also may have taken place around 12:52 p.m. and 1:18 p.m.Wichita is near the Nemaha Ridge, or Humboldt Fault line. ", "The Meers fault scarp, southwestern Oklahoma", "Neotectonic and Paleoseismic Analysis of the Northwest Extent of Holocene Surface Deformation along the Meers Fault, OklahomaNeotectonic and Paleoseismic Analysis of the Northwest Extent of Holocene Surface Deformation", 10.1130/0016-7606(1995)107<0098:SCOHRO>2.3.CO;2, "Investigation of the Meers fault in southwestern Oklahoma (NUREG/CR--4937). It may have begun as a rift margin fault in the Proterozoic-Cambrian[13] associated with the Southern Oklahoma Aulacogen[39] but its maximum activity took place during the Mississippian and Permian when the Wichita Mountains and the Slick Hills were offset along it by about 2 kilometers (1.2 mi)[13] and the Meers Valley formed along the fault. Slip on the Springer detachment is dissipated along a number of forward-propagating imbricates, culminating in the Carter-Knox structure ( Turko and Mitra, 2020a ). The New Madrid seismic zone is located in the northern part of what has been called the Mississippi embayment. [58] Earthquakes in Oklahoma have been observed in the areas of the southern Oklahoma aulacogen and of the Amarillo-Wichita uplift; in southwestern Oklahoma they are rare and of moderate intensity.
