wisconsin fault line
The Great Lakes tectonic zone (GLTZ) is bounded by South Dakota at its tip and heads northeast to south of Duluth, Minnesota, then heads east through northern Wisconsin, Marquette, Michigan, and then trends more northeasterly to skim the northernmost shores of lakes. KML (Google Earth-type) files and GIS shape files are also available for download from the site. An online map of United States Quaternary faults (faults that have been active in the last 1.6 million years) is available via the Quaternary Fault and Fold Database. Harlan's reconstruction of this pivot is shown to the right.  The collision is interpreted to have happened obliquely at an angle, beginning in the west. Ano ang Imahinasyong guhit na naghahati sa daigdig sa magkaibang araw?  The boundary that separates the two colliding bodies is the Great Lakes tectonic zone; it is a fault zone of highly deformed rocks. :2 These Huronian and Snowy Pass sedimentary rocks are similar, each having 2,450- to 2,100-million-year-old epicratonic rifts succeeded by a 2,100- to 1,800-million-year-old passive sedimentary margins. Filter by magnitude: all. The giant tremors, which rocked buildings, knocked dishes off shelves and pictures off walls and put some pedestrians off balance, were felt in surrounding counties, too, but not as strongly.”. The area had been previously shaken by the 1909 Wabash River earthquake, causing damage assessed at VII (Very strong) on the Modified Mercalli scale across the Wisconsin-Illinois border. Several earthquakes have been documented in Minnesota in the last 120 years, with at least six in the GLTZ. Trench located approximately 3 miles NW of downtown Napa, CA. What is a fault and what are the different types? In addition to the earthquakes shown above, there might have been other earthquakes felt in Southeastern Wisconsin. How do I find the nearest fault to a property or specific location? :9 By 2,100 million years ago the Superior and Wyoming provinces had completely separated. , Wisconsin has had no earthquakes along the GLTZ, Michigan's Upper Peninsula has had four earthquakes in the vicinity of the GLTZ – Negaunee, Newberry and two in Sault Ste. The Earth is formed of several layers that have different physical and chemical properties.  The locals' initial impression was that an explosion had taken place. The Blue Draw Metagabbro is now 935 km (580 mi) west of Sudbury and remains about 150 km (90 mi) south of the Superior-Wyoming provinces' junction. The orange, bean-shaped area represents the dense, magnetic body of rock on the east side of the fault beneath Santa Rosa. An earthquake is ground shaking caused by a sudden movement of rock in the Earth’s crust. The area hardest hit was a 7,770 square kilometers (3,000 sq mi) strip of land in southeastern Wisconsin, while the earthquake was felt over a much more extensive 99 miles (159 km) wide area stretching across the Wisconsin-Illinois border, and to Lake Michigan and Waukesha. The largest earthquake on record for Wisconsin occurred on 05/12/2014, with a depth of 10.0 miles and a magnitude of 5.1 on the Richter scale in Dane County, WI. “Milwaukee shook in the grip of its first recorded earthquake for half a second at 3:25 p. m. yesterday – and can thank its stars that the quake lasted no longer. Time: Mag. 5 years ago. Events below magnitude 2.0 are also excluded because these are so rarely felt by people and are relatively common events. These and other young faults exposed in area help reveal the latest kinematic (movement) and paleostress histories of the mountain block. Why are there so many faults in the Quaternary Faults Database with the same name? :4, Recent radiometric age data indicates that there are four crystalline rock complexes 3,400 million years old in the Lake Superior region. Seismographs record the motion of the ground during an earthquake. 20 cool facts about the New Madrid Seismic Zone-Commemorating the bicentennial of the New Madrid earthquake sequence, December 1811-February 1812 [poster]; 2011; GIP; 134; Williams, R. A.; McCallister, N.S. , Recent geologic mapping in the Marquette, Michigan, U.S., area provides information of the structure for the zone along a 10 km (6.2 mi) strike. In a first of its kind study U.S. Geological Survey (USGS) and Duke University seismologists have used tiny "microearthquakes" along a section of California’s notorious San Andreas Fault to create unique images of the contorted geology scientists will face as they continue drilling deeper into the fault zone to construct a major earthquake "observatory. However, the earthquake caused no serious damage or casualties. The data was obtained from the US Geological Survey (USGS) and from the UW Milwaukee Geosciences Seismic Center.  During the collision with the Superior province, the MRV gneissic block was thrust up onto the Superior province's edge; this resulted in a thrusted crumpled fault tens of kilometers wide producing a mountain range, and a shear zone which defines the boundary between the two terranes. Collision began along the Great Lakes tectonic zone with the Algoman mountain-building event and continued for tens of millions of years. My friend is freaking out because of the earthquakes that are happening near where we live. Additional descriptions of earthquakes felt in Wisconsin are described by the USGS. Two faults (located on either side of project geologist Chris Fridrich) cutting Pleistocene fluvial gravels on the northern edge of the Poncha mountain block. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other. The 2,170-million-year-old intrusive events that affected the Superior and the Wyoming cratons indicate that the plume had moved 330 km (210 mi) west, centered in the opening between the Superior province and the rifting Wyoming province. This earthquake occurred on May 6, 1947. What is the hink-pink for blue green moray? The earthquake that occurred Wednesday didn't happen near a fault line in Tennessee, for the most part, the state is free of any faults that would suggest a vulnerability to earthquakes. How do I find fault or hazard maps for California? It’s measured in g, or m/s². Damage consisted of broken windows and fallen porcelain, pots and dishes. How much does does a 100 dollar roblox gift card get you in robhx?  After the oceanic crust is consumed, the two blocks meet and the subducting oceanic crust pulls the attached continental block under the other. :409 A stretching lineation (line of tectonic transport) in the mylonite foliation plunges 42° in a S43°E direction. Fault lines are hard to find in our region due to so many trees and other plant life … The fault surface can be vertical, horizontal,... Field, E.H., and 2014 Working Group on California Earthquake Probabilities, 2015, UCERF3: A new earthquake forecast for California’s complex fault system: U.S. Geological Survey 2015–3009, 6 p., http://dx.doi.org/10.3133/fs20153009. There are 2 earthquake incidents in Wisconsin on record since 1931. These fault segments are given a different value for name, number, code, or dip direction and so in the database each segment occurs as its own unique entity.
