[22], Beginning in February 1989, self-proclaimed climatologist Iben Browning, who claimed to have predicted the 1980 eruption of Mount St. Helens and the 1989 Loma Prieta earthquake – predicted a 50% probability of a magnitude 6.5 to 7.5 earthquake in the New Madrid area sometime between December 1 and December 5, 1990. The Humboldt Fault (red) and Midcontinent Rift System (green) in Kansas and Nebraska The Humboldt Fault or Humboldt Fault Zone, is a normal fault or series of faults, that extends from Nebraska southwestwardly through most of Kansas. Stephenson, W.J., K.M. [23][24] Browning appears to have based this prediction on particularly strong tidal forces being expected during that time, and his opinion that a New Madrid earthquake was "overdue;" however, seismologists generally agree that no correlation exists between tides and earthquakes. This answer was incorrect. As a result, we are not accepting new comments or questions about Google Earth. A GIS database of geologic units and structural features in Kansas, with lithology, age, data structure, and format written and arranged just like the other states. [6], Dendrochronology (tree ring) studies conducted on the oldest bald cypress trees growing in Reelfoot Lake found evidence of the 1811–1812 series in the form of fractures followed by rapid growth after their inundation, whereas cores taken from old bald cypress trees in the St. Francis sunklands showed slowed growth in the half century that followed 1812. 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. How can I find the primary and secondary global fault lines. Most of the seismicity originates between 3 and 15 miles (4.8 and 24.1 km) beneath the Earth's surface.

We’ve talked about Earthquakes quite a lot over the years, as Google Earth is a great tool for visualizing those types of events. [17][18] Also, some form of heating in the lithosphere below the area has been suggested to be making deep rocks more plastic, which would concentrate compressive stress in the shallower subsurface area where the faulting occurs.[19][20]. People are worried if the recent quakes could trigger the "Big One," on the San Andreas Fault line— the boundary between the North American and Pacific tectonic plates. [15] In 2008 in the nearby Wabash Valley Seismic Zone, a similar magnitude 5.4 earthquake occurred with its epicenter in Illinois near West Salem and Mount Carmel. All Rights Reserved.

Kansas is not particularly earthquake prone, ranking 45th out of 50 states by damage caused. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright 2005-© 2020 Frank Taylor. This map gives an overview of geologically young faults and is intended to help in evaluation of the potential activity of faulting nationally. It is southwest of the Wabash Valley Seismic Zone. Website showing earthquake activity and historical information for Kansas. Map via USGS. [30], Reelfoot Rift and the New Madrid Seismic Zone in a 3D topographic image, Magnetic potential map of the Reelfoot Rift, Petersen, Mark D.; Moschetti, Morgan P.'; Powers, Peter M.' et al. He has created an excellent overlay that shows the fault line in comparison to infrastructure along the path of it. The quake damaged the civic building at Henderson, Kentucky, and was felt in 23 states.

The USGS also has some solid fault line maps that you can use in Google Earth. The 1895 event had its epicenter near Charleston, Missouri.

In 1992, the USGS agreed to help compile maps and fault descriptions for countries in the Western Hemisphere (North, Central, and South America, as well as Australia and New Zealand). What are the most dangerous fault lines in the USA? Contours in Kansas and Nebraska modified from Burchett et al. Although some of these ideas have gained some acceptance among researchers, they have not been accepted by the National Earthquake Prediction Evaluation Council, which advises the USGS. As of the time of this writing, it has been 356 years ago and is well within the potential period of its movement. Yes, the New Madrid fault line runs through Kansas. interpreted the lack of similar signals elsewhere in the chronology as evidence against large New Madrid earthquakes between those years and 1811. This blog and its author are not an official source of information from Google that produces and owns Google Earth In 2009, two studies based on eight years of GPS measurements indicated that the faults were moving at no more than 0.2 mm (0.0079 in) a year. The report found that there would be significant damage in the eight states studied – Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri, and Tennessee – with the probability of additional damage in states farther from the NMSZ.

The New Madrid Seismic Zone (/ˈmædrɪd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri. By studying evidence of past quakes and closely monitoring ground motion and current earthquake activity, scientists attempt to understand their causes and recurrence intervals. The New Madrid fault system was responsible for the 1811–12 New Madrid earthquakes, and has the potential to produce large earthquakes in the future.

The report estimated 86,000 casualties, including 3,500 fatalities, 715,000 damaged buildings, and 7.2 million people displaced, with two million of those seeking shelter, primarily due to the lack of utility services. The USGS has a faults website that includes an interactive fault map that allows users to views a map … (1995). [citation needed]. The USGS issued a fact sheet in 2009 stating the estimate of a 7–10% chance of a New Madrid earthquake of magnitude comparable to one of the 1811–1812 quakes within the next 50 years, and a 25–40% chance of a magnitude 6.0 earthquake in the same time frame. [8], Hundreds of aftershocks of the 1811–1812 series followed over a period of several years. The fault line is growing in interest for a simple reason that Ervin explains: The last known activity along this fault line was the year 1658 and is estimated to be active every 300 years plus or minus 100 years. [16], Since other ancient rifts are known to occur in North America, but not all are associated with modern earthquakes, other processes could be at work to locally increase mechanical stress on the New Madrid faults. Shedlock, and J.K. Odum.

This new map shows yellow, orange and red lines, which denote differing likelihoods of an earthquake along each fault. [25] This contrasts to the rate of slip on the San Andreas Fault, which averages up to 37 mm (1.5 in) a year across California. [24], The lack of apparent land movement along the New Madrid fault system has long puzzled scientists. The largest NMSZ earthquake of the 20th century was a 5.4-magnitude quake (although it was reported as a 5.5 at the time) on November 9, 1968, near Dale, Illinois. The period passed with no major earthquake activity in New Madrid or along the 120-mile (190 km) fault line. (1981); Nemaha fault trace in Kansas Direct economic losses, according to the report, would be at least $300 billion. Earthquake Hazard in the New Madrid Seismic Zone Remains a Concern USGS (2009). See the related link for a USGS map of quaternary faults in Kansas. Kansas geologic map data. The New Madrid Seismic Zone (/ ˈ m æ d r ɪ d /), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri. / | List If you have a question, use the official Google Earth and Maps Forums or the Google Earth Community Forums.

Because the tree ring record in Reelfoot Lake and the St. Francis sunk lands extend back to 1682 and 1321, respectively, Van Arsdale et al.

The faults responsible for the NMSZ are embedded in a subsurface geological feature known as the Reelfoot Rift that formed during the breakup of the supercontinent Rodinia in the Neoproterozoic era (about 750 million years ago)[citation needed]. [25] Seth Stein, the leader of the research group, published these views in a book, Disaster Deferred, in 2008. This relative weakness is important, because it would allow the relatively small east-west compressive forces associated with the continuing continental drift of the North American plate to reactivate old faults around New Madrid, making the area unusually prone to earthquakes in spite of it being far from the nearest tectonic plate boundary.

Many of the published accounts describe the cumulative effects of all the earthquakes (known as the New Madrid Sequence), so finding the individual effects of each quake can be difficult. See the related link for a USGS map of quaternary faults in Kansas. If you visit their Quaternary Faults in Google Earth page, you’ll find a variety of KML files that you can download and explore in Google Earth. [3] Archaeological studies have found from studies of sand blows and soil horizons that previous series of very large earthquakes have occurred in the NMSZ in recent prehistory.
