Map Of The New Madrid Fault Line

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. 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. It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg.

This map shows earthquakes (circles) of the New Madrid and Wabash Valley seismic zones (orange patches). Red circles indicate earthquakes that occurred from 1974 to 2002 with magnitudes larger than 2.5 located using modern instruments (University of Memphis). New Madrid earthquake map: Topographic map showing earthquakes greater than magnitude 2.5 (circles) of the central United States. Red circles are earthquakes that occurred after 1972 from the USGS Preliminary Determination of Epicenters catalog.

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.

While not as well known for earthquakes as California or Alaska, the New Madrid Seismic Zone (NMSZ), located in southeastern Missouri, northeastern Arkansas, western Tennessee, western Kentucky and southern Illinois, is the most active seismic area in the United States, east of the Rocky Mountains.

The New Madrid Fault extends approximately 120 miles southward from the area of Charleston, Missouri, and Cairo, Illinois, through Mew Madrid and Caruthersville, following Interstate 55 to Blytheville, then to Marked Tree Arkansas. It crosses 5 state lines and cuts across the Mississippi River in 3 places and the Ohio River in 2 places.

An earthquake prompted by the New Madrid Seismic Fault Line occurs at 3 and 15 miles depth. Shallow earthquakes equate to more violent shaking on the surface due to having much less insulation to absorb the seismic waves being thrust out from the earthquake's epicenter.

The current best guess is that the New Madrid Seismic Zone (NMSZ) is about 30 years overdue for a magnitude 6.3 earthquake — one strong enough to damage ordinary buildings and overturn heavy furniture. A magnitude 7.6 earthquake, as serious as the 1811-12 series, may arrive by 2069.

New Madrid earthquakes of 1811-12, series of three large earthquakes that occurred near New Madrid, Missouri, between December 1811 and February 1812. There were thousands of aftershocks, of which 1,874 were large enough to be felt in Louisville, Kentucky, about 190 miles (300 km) away. The number of lives lost from the earthquakes remains unknown; however, scholars note that the number was.

The New Madrid Fault is much more powerful. Map by uwgb.edu As described by USGS: " In 1811, the extent of the area that experienced damaging earth motion, which produced Modified Mercalli Intensity greater than or equal to VII, is estimated to be 600,000 square kilometers.

Expected shaking intensity of a magnitude 7.5 earthquake on the New Madrid central fault. Greens to yellows indicate moderate to strong shaking; oranges to reds indicate severe to extreme shaking and moderate to heavy damage. Credit: US Geological Survey Human and Economic Risks

New Madrid Fault. Jun 24, 2021. In the last week of June, the General Land Office is exploring the New Madrid Fault, also known as the New Madrid Seismic Zone. This earthquake-prone region has been extremely active in the past and scientists predict it will be just as active in the near future. Read more on ArcGIS Story Maps. The GLO website.

Most maps show the north end of the New Madrid fault about 20 miles west of this point, though some fault lines and quakes continue just north of here (in the distance of photo), through Paducah, Ky. and connect with the Wabash Valley fault near Evansville, IN.

The New Madrid Seismic Zone 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.

The New Madrid Seismic Zone is unique, though, because by all accounts it should not even exist in the first place, Sandvol said. "The (fault) is not even supposed to be there according to.

The New Madrid fault system contains two types of faults, a strike slip segment oriented to the northeast, running from Marked Tree, AR to Caruthersville, MO, and a northwest trending reverse fault that rests below the New Madrid region. Material on the northwest side of the strike-slip fault moves northeast, and up the ramp.St.

As of January 12, 2017, the USGS maintains a limited number of metadata fields that characterize the Quaternary faults and folds of the United States. For the most up-to-date information, please refer to the interactive fault map. Reelfoot scarp and New Madrid seismic zone (Class A) No. 1023 Last Review Date: 1994-04-12

The composition of geologic materials between these points is a major factor in transmitting the energy to buildings and other structures on the Earth's surface. Earthquake strength is recorded by a seismograph and is.

The New Madrid Fault, also called the New Madrid seismic zone, is actually a series of faults, or fractures, at a weak spot in the earth's crust called the Reelfoot Rift. It lies deep in the earth and cannot be seen from the surface. The fault line runs roughly 150 miles from Arkansas into Missouri and Illinois. In 1811-1812, it was responsible for the most violent series of earthquakes in.
