University of Michigan experts are available to comment. In Detroit, it was an intensity II-III, while in Chicago it was an intensity V. 1895: A major earthquake originated in Charleston, Missouri. - Hough. Source: http://www.fema.gov/earthquake/earthquake-hazard-maps. An historical record of earthquakes with epicenters in Michigan is shown on Table 1. [11] The quartz biotite gabbro is medium- to coarse-grained,[11] the Climax quartz monzonite is medium-grained. The rigid nature of the bedrock that runs throughout the Midwest allows seismic waves to travel across the region. [8]:3 Late-stage dikes and sills of diabase, quartz-feldspar fine-grained instrusive rocks (aplite) and quartz-feldspar-mica coarse-grained intrusive rocks (pegmatite) are common. [13]: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. It was felt in Grand Rapids as an intensity V. 1935: An earthquake registering 6.1 on the magnitude scale originated in Timiskaming Quebec. In: T. Mikumo, K. Aki, M. Ohnaka, L.J. [10]:1890 The sublayer consists of a mass of basic to ultrabasic inclusions of varying size and frequency of occurrence. Jump to Navigation Significant Earthquakes - 2015. The ground shakes in Detroit from those quakes was felt as a V. Additional notable out-of-state earthquakes felt in Michigan: There have been several earthquakes that have impacted Michigan since 2000. [13]:9, In the northern Black Hills of southwest South Dakota the 2,600- to 2,560-million-year-old Precambrian crystalline core, the Blue Draw Metagabbro, is a 1 km (0.62 mi) thick layered sill. 1980: An earthquake registering 5.2 on the magnitude scale originated in northeast Kentucky, where it was an intensity VII. [8]:8 Lithologies of the rocks are usually gneissose and migmatitic. The geologic record of pre-1811 earthquakes also reveals that the New Madrid seismic zone has repeatedly produced sequences of major earthquakes, including several of magnitude 7 to 8, over the past 4,500 years. Noida, like most of the National Capital Region, is a high-damage risk earthquake zone, also known as earthquake zone 4 or seismic zone 4. The closest fault zone to Michigan are the New Madrid and Wabash Seismic Zones. [10]:1890[note 1] The structure consists of the Sudbury Igneous Complex, a differentiated sequence of intrusive volcanic rocks – norite, gabbro and Updated 2 Dec 2020 06:37 GMT - There were no significant earthquakes in or near Michigan during the past 30 days. Greece and Turkey are both situated in one of the world's most active earthquake zones. Most of Michigan ranks in the lowest seismic zone category and is 36 th in the U.S. for earthquake hazards according to the USGS. [8]:8, The Sudbury Basin structure is located in Greater Sudbury[10]:1891 at the erosional boundary between the Archean Superior province and the overlying sequence of early Proterozoic continental margin deposits. [11], In the eastern Sudbury area the rock is highly crystalline hornblendic gneiss, which apparently dips at a rather low angle toward the southeast. Seismic hazard is the hazard associated with potential earthquakes in a particular area, and a seismic hazard map shows the relative hazards in different areas. The zone, colored red on the map, is called the New Madrid Seismic Zone. In general, greater shaking is expected in regions closer to active faults. This map and table shows where Minnesota's earthquakes have occurred. [5]:409 Shear zone boundaries are subparallel and strike N60°W; the foliation in mylonite within the GLTZ strikes N70°W and dips S75°W. When stress that has accumulated over time eventually exceeds the rock’s strength, rupture occurs, generally along a plane of weakness called a fault. It was felt as an intensity II-IV at various locations in and around Detroit. [13]:2 Radiometric dating shows that the Wyoming province's Blue Draw Metagabbro was undergoing rifting at 2,480 million years ago, the same time the emplacement of the 250 km (160 mi) long belt of mafic layered intrusions in the Sudbury region. Learn more about the causes and effects of earthquakes … The … This program can be used to obtain the earthquake ground motion parameters needed to design structures for specific geographic locations in accordance with the latest building code reference documents. [4] The Algoman Mountains had been built and then eroded into sediments that covered the area. Causes of Earthquakes. There are 43 earthquake incidents in Michigan on record since 1931. May 2015 in The Pub. Although you can’t control the seismic hazard in the community where you live or work, you can influence the most important factor in saving lives and reducing losses from an earthquake: the adoption and enforcement of up-to-date building codes. Questions? This region has a low to moderate level of seismicity when compared to the more active seismic zones to the east, along the Ottawa River and in Quebec. The swarm of earthquakes began on September 30 in the Brawley seismic zone. Algoman orogeny added landmass to the Superior province by volcanic activity and continental collision along a boundary that stretches from present-day South Dakota, U.S., into the Lake Huron region near Sudbury, Ontario, Canada. [13]:9, By 2,100 million years ago, the Wyoming craton is thought to have completely separated from the southern Superior province, this is consistent with the occurrence of a 2,076- to 2,067-million-year-old hotspot centered just south of the Superior province and east of the MRV. [6]:145 This is when the Wyoming province is hypothesized to have drifted away from the Superior province. Designated earthquake, hurricane or other emergency shelters. 2015-12-30 07:39:29 UTC 52.4 km. [4] The growth of the Superior province greenstone-granitic terranes ended with the suturing of the Minnesota River Valley gneiss terrane to the basaltic Wawa subprovince. 2.0+ 3.0+ 4.0+ 5.0+ [smaller] [bigger] Today | Yesterday | Past month | All time. The Holland, Michigan tsunami started at 4:10 AM, just 2 minutes after the earthquake occured.

The state averages 1 earthquakes per year. [13]:9 In southcentral Wyoming province there is a 2,170 ± 8-million-year-old quartz diorite dike of Wind River Range. [4] Similar intrusions farther east along the GLTZ show later dates, reinforcing the theorized closure from west to east. [4] Fragmentation of this Archean supercontinent began around 2,450 million years ago under a hotspot near Sudbury and was completed by around 2,100 million years ago. The 2,125- to 2,090-million-year-old mafic magmatic events affecting the Superior and Wyoming cratons show the hotspot having moved 500 km (310 mi) west from Sudbury, and the two provinces have rifted so that they are separated by 100 km (60 mi). There is broad agreement in the scientific community that a continuing concern exists for a major destructive earthquake in the New Madrid seismic zone. 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. It is a 1,400 km (870 mi) long paleosuture that separates the more than 3,000-million-year-old Archean gneissic terrane to the south – Minnesota River Valley subprovince – from the 2,700-million-year-old Late Archean greenstone-granite terrane to the north – Wawa Subprovince of the Superior province. Even though Michigan is categorized as having a very low hazard risk for earthquakes, the state does experience earthquakes. USGS Earthquake Hazards Program, responsible for monitoring, reporting, and researching earthquakes and earthquake hazards . [6]:165, The Northern and Southern complexes of the Upper Peninsula are highly migmatized and intensely foliated, with the intensity of foliation increasing toward margins. 11 Northwestern its first loss of the season with a 29-20 victory Saturday.The Wildcats (5-1, 5-1) were coming off a 17-7 victory over Wisconsin that put them in contention for a spot in the College Football Playoff. Title. Not only was this one of the biggest earthquakes in Michigan’s history, but it came less than two months after a larger earthquake occurred less than 30 miles away. of Examples: Monday, today, last week, Mar 26, 3/26/04. granophyre – overlain by breccias and metasedimenary rocks. It doesn't seem to work when the url is typed into Google. The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and … 2015-12-30 01:48:57 UTC 7.0 km. Migrated composite section of COCORP north-south seismic-reflection profiles, Minnesota S4 3. Kalamazoo - It was the first earthquake in Michigan in years with a rating of 4.2; Grand Rapids - Lying on sofa, felt weak tremor lasting 4 seconds. [8]:8 These Late Archean rocks form a roughly north–south belt lying south of Marquette extending to the Michigan-Wisconsin border. A magnitude 4.9 struck near Resolute, Nunavut Sunday night at a depth of 10 kilometres, according to the U.S. Geological Survey. Earthquakes in Virginia commonly occur on blind faults that do not reach earth’s surface. We have a seismic zone that produces earthquake clusters. Earthquake News Today. Ruff and P.K.P. Department of Geological Sciences, Unir~ersity of Michigan, Ann Arbor, MI 48109, USA (Received June 14, 1991; revised version accepted March 2, 1992) ABSTRACT Ruff, L.J., 1992. Filter by magnitude: all. An episode of hotspot gabbro magmatism occurred 2,480 million years ago at the eastern edge of the Wyoming craton,[13]:1 south of current-day Sudbury. [8]:8 The western part of the Southern Complex shows intricate phases of folding and foliation. This assessment is based on decades of research on New Madrid earthquakes and related phenomena by d… Some people often use the term “seismic zone” to talk about an area with an increased risk of seismic activity, while others prefer to talk about “seismic hazard zones” when discussing areas where seismic activity is more … H [13]:2 Intrusion of the 2,475- to 2,445-million-year-old Matachewan-Hearst Mafic Dike Swarm and the 2,490- to 2,475-million-year-old East Bull Lake suite of layered mafic intrusive rocks are interpreted as indicating early Paleoproterozoic, mantle-hotspot driven rifting centered near Sudbury, Ontario, during the onset of Kenorland breakup.
