The red dots show larger-magnitude earthquakes in Minnesota, Wisconsin, Michigan's Upper Peninsula and southern Ontario. The earthquake near Minnesota's western "bulge" is the Morris earthquake. This map and table shows where Minnesota's earthquakes have occurred. Earthquakes 1, 6, 9, 11, 15 and 18 are in the Great Lakes tectonic zone.
The Southern Great Lakes Seismic Zone is a zone of low to moderate seismic activity surrounding Lake Erie and Lake Ontario in Canada and the United States. [ 1 ] See also
The Charlevoix region has been the location of at least five magnitude six or larger earthquakes over the last 350 years, including the 1925 Charlevoix–Kamouraska earthquake. At the Lower St Lawrence zone the largest recorded earthquakes are about magnitude five.
Earthquakes in the New Madrid and Wabash Valley seismic zones from 1974 to 2002, with magnitudes larger than 2.5. The zone had four of the largest earthquakes in recorded North American history, with moment magnitudes estimated to be as large as 7 or greater, all occurring within a 3-month period between December 1811 and February 1812. Many of ...
2019 Ridgecrest earthquakes: California, Nevada, Arizona: Three earthquakes struck California between July 4 and July 5. The main earthquake was a 7.1 magnitude, as two others were 5.4 and 6.4 magnitudes. At least one was killed and several others were injured. The main earthquake was the strongest earthquake to hit the region in 20 years. [28 ...
Tectonic map of Alaska and northwestern Canada showing main faults and historic earthquakes Denali Fault and the Denali National Park boundary. The Denali Fault is a major intracontinental dextral (right lateral) strike-slip fault in western North America, extending from northwestern British Columbia, Canada to the central region of the U.S. state of Alaska.
With over 200 small earthquakes occurring each year, the Charlevoix Seismic Zone is one of the most active seismic zones in Canada. Since 1663, five damaging earthquakes have occurred in the area, including a magnitude 7.3-7.9 event in 1663 , a magnitude 7.0 event in 1791, a magnitude 6.0 event in 1860, a magnitude 6.5 event in 1870 and a ...
A strong earthquake on the Wasatch Fault could trigger landslides, cause mass liquefaction, and flooding of low-lying areas forming near lakes due to subsidence and tilting. The quake may also rupture the surface causing displacement of up to 20 feet (6.1 m), and severely damage gas, electric, water, communication, and transportation lifelines ...
