[64] In particular, it indicates that the Mid-Continent is not free of earthquakes and that the absence of recent seismicity does not rule out the presence of active faults. The CVSZ, the New Madrid seismic zone, and the central Oklahoma seismic zone (COSZ) are all bisected by major river systems. Despite the considerable variability in seismic … Seismic Risk of the Meers Fault, SW Oklahoma: A Hoary Giant or Great Imposter? When? Southern Oklahoma has long been recognized as the home to a series of very large and complex intraplate structures that are exposed in the Wichita and Arbuckle Mountains. 2020-12-07 07:32:32 UTC 2.1 magnitude, 4 km depth Alva, Oklahoma, United States 2.1 magnitude earthquake 2020-12-07 07:32:32 UTC at 07:32 December 07, 2020 UTC [1], The Meers fault is a reverse fault[7] (at first it was interpreted to be a normal fault[8]) with a straight path despite a variable topography;[9] it probably does take the form of a broad dislocation rather than of a plane[10] and its expression varies depending on the substrate rock. Andrew Cullen / Warwick Energy & University of Oklahoma STATEMENT of the PROBLEM: The southern edge of the Anadarko basin in SW Oklahoma is defined by a regional fault system that records Pennsylvanian-aged inversion of a failed Cambrian intra-continental rift; an aulacogen formed during the break-up of … Other areas, such as the Wabash Valley and East Tennessee Seismic zones also produce earthquakes on a regular basis. The central Virginia seismic zone (CVSZ), New Madrid, MO, seismic zone, and the central Oklahoma intraplate seismic zone are all bisected by major river systems.

[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. (AP) — Five low intensity earthquakes have rattled part of the Wichita area since Thanksgiving, but a Kansas expert on seismic activity says residents of the state's largest city should not be overly concerned about a larger, more destructive quake occurring there. The New Madrid Seismic Zone, sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes in the southern and midwestern United States, stretching to the southwest from New Madrid, Missouri. [5] The fault scarp is located on private land;[6] the southeastern part runs through farmland and the northwestern part runs through hilly terrain. The west-northwest-trending rift appears to follow an older Proterozoic line of structural weakness in the crust. [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. [9] The ratio of the horizontal to vertical motion is about 1.3–1.5[14] or about 2:1[12] although the amount of horizontal movement on the fault is controversial. A high-resolution seismic-reflection survey over part of the Meers fault scarp in Comanche County, Oklahoma, provides an improved understanding of the shallow structure associated with the fault zone. [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. The quake, which was centered in the town of Puturge, struck at... TIRANA, Albania (AP) — Albanian prosecutors indicted 16 investors, construction experts and local officials Friday on murder and other charges resulting from fatal building collapses after an earthquake a year ago. [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.
