Most earthquakes occur under the St. Lawrence River, within a triangular zone defined by the towns of Baie-Comeau, Sept-Iles, and Matane on the south shore.Although the network is not sufficiently dense to accurately determine earthquake focal depths, it can be assumed that the active zone lies in the mid- to upper crust, between 5 and 25 km depth, similar to the Charlevoix Seismic Zone (CSZ). Michael Bliss.
At some time in the future, these plates will snap loose, generating a huge offshore "subduction" earthquake - one similar to the 1964 M=9.2 Alaska earthquake, or the 1960 M=9.5 Chile earthquake. A decade will, on average, include three events greater than magnitude 5. The seismograph network of Earthquakes Canada can detect all events exceeding magnitude 3 in eastern Canada and all events magnitude 2.5 or greater in densely populated areas.The causes of earthquakes in eastern Canada are not well understood.
From some focal mechanism determinations (see references below) and by analogy with the CSZ, most earthquakes probably cluster along or between the mapped Iapetan faults (also called St. Lawrence paleo-rift faults), beneath the Logan's line and the Appalachians.A Lower St. Lawrence earthquake occurs every five days on average.The Northern Appalachians Seismic Zone includes most of New Brunswick and extends into New England down to Boston.The Laurentian Slope Seismic Zone comprises an area off Canada's southeast coast, which includes the Grand Banks of Newfoundland.
Canada like just about everywhere in the world has fault lines. More recently, on March 16, 1999The region is closely monitored by a network of five local stations of the About 60 events are recorded in the LSZ annually. The continual shifting of large segments of the earth's crust, called tectonic plates, causes more than 97% of the world's earthquakes. Every fault line in British Columbia From the benign to those which threaten major cities, these are the fault lines responsible for earthquakes across British Columbia. By the time Lewis and Clark arrived on the West Coast in 1805, it had been 105 years since the Cascadia Subduction Zone last ruptured, sending a large portion of the Pacific Ocean roaring toward the coast. Eastern Canada is located in a stable continental region within the North American Plate and, as a consequence, has a relatively low rate of earthquake activity. Social Sharing In relation to Canada, fault lines are political, social and economic cracks that divide people and regions and they also threaten to destabilize the integrity of Canada as a nation. Each year, seismologists with the Geological Survey of Canada record and locate more than 1000 earthquakes in western Canada. The St. Elias region of the southwest Yukon Territory, northwest British Columbia, and southeast Alaska is one of the most seismically active areas in Canada. Magnitude 6-plus earthquakes have occurred in the Richardson Mountains of the Yukon Territory (M=6.2 in May, 1940; M=6.5 in June, 1940, and M=6.6 in March, 1955).South of 60 N, seismicity in the interior and Rocky Mountain areas drops off rapidly.
Two magnitude 5 earthquakes (1905, northern Michigan, and 1928, northwest of Kapuskasing) have occurred in this region.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. Canada has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 3 earthquakes in the past 7 days; 25 earthquakes in the past 30 days; 324 earthquakes in the past 365 days In 1986 a magnitude 5.5 earthquake occurred near Prince George, causing some minor damage.Seismic activity in the prairie region south of 60 N is predominantly confined to southern Saskatchewan in a zone that continues into Montana.
As most earthquakes occur under the St. Lawrence River, between the regions of the Quebec North Shore and the Lower St. Lawrence, this zone is sometimes refered to as the "Lower-St. Lawrence-Quebec North Shore" Seismic Zone.Unlike the Charlevoix Seismic Zone, no large earthquake has ever been reported or recorded in the LSZ.

In relation to Canada, fault lines are political, social and economic cracks that divide people and regions and they also threaten to … Over the past 30 years, on average, 2 to 3 magnitude 2.5 or larger earthquakes have been recorded in the southern Great Lakes region.
Published May 2, 2000 Updated May 2, ... More than ever, Canada has become politically two countries. It is this squeezing of the crust that causes the 300 or so small earthquakes that are located in southwestern British Columbia each year, and the less-frequent (once per decade, on average, damaging crustal earthquakes (e.g., a magnitude 7.3 earthquake on central Vancouver Island in 1946). CSZ earthquakes occur in the Canadian Shield, between the surface and 30 km depth, beneath Logan's line and the Appalachians.On average, an earthquake occurs in the Charlevoix region every day and a half.Located some 400 km downstream from Quebec City in the estuary of the St. Lawrence River, the Lower St. Lawrence Seismic Zone (LSZ) is a seismically active region of eastern Canada.
A magnitude 3 event is sufficiently strong to be felt in the immediate area, and a magnitude 5 event is generally the threshold of damage.
