Through this book you will see where the Mississippi River ran backwards and where, for a time, the land surface rippled like the waves of an ocean, changing the face of the earth forever. The study area includes the seismically active region known as the Western Quebec Seismic Zone (WQSZ). Pointe-de-Saint-Valliers sits on the south-western fringe of the Charlevoix Seismic zone, where the weaknesses in the crust created by the meteor impact in addition to the late Proterozoic faults release the . Qualitative Aspects of Chromo-Stereoscopy for Depth Perception, Photogrammetric Engineering and Remote Sensing, 63 (2): 193-203. http://www.ccrs.nrcan.gc.ca/ccrs/rd/sci_pub/bibpdf/1530.pdf, Toutin, Th., B. Rivard, 1997. From focal mechanisms of CSZ earthquakes, it is known that most earthquakes represent strike-slip to reverse faulting on fault planes with varied orientations (Lamontagne, 1999). It was felt throughout Western Quebec, Ottawa, and other parts of Ontario, and as far away as Ohio in the U.S.[6][7], Coordinates: .mw-parser-output .geo-default,.mw-parser-output .geo-dms,.mw-parser-output .geo-dec{display:inline}.mw-parser-output .geo-nondefault,.mw-parser-output .geo-multi-punct{display:none}.mw-parser-output .longitude,.mw-parser-output .latitude{white-space:nowrap}46°22′N 76°43′W / 46.37°N 76.71°W / 46.37; -76.71, "The 16 September, 1732, Montréal earthquake", "The 1935 Magnitude 6.1 Timiskaming earthquake", "The 1944 Magnitude 5.8 Cornwall-Massena earthquake", "Magnitude 5.0 - ONTARIO-QUEBEC BORDER REGION, CANADA", "2013-05-17: M=5.2 - 18 km NE of Shawville, QC - felt", "2013-05-17: M=4.1 - 20 km NE of Shawville, QC - aftershock", https://en.wikipedia.org/w/index.php?title=Western_Quebec_Seismic_Zone&oldid=1004388647, Creative Commons Attribution-ShareAlike License, This page was last edited on 2 February 2021, at 10:40.

Contrary to popular belief, Eastern Canada is more at risk of earthquakes than perceived. British Columbia outer coast. Interested in starting, or contributing to a conversation about an article or issue of the RECORDER? Here and there earthquakes are more numerous, for example in the New Madrid seismic zone centered on southeastern Missouri, in the Charlevoix-Kamouraska seismic zone of eastern Quebec, in New England, in the New York - Philadelphia - Wilmington urban corridor, and elsewhere. The map is a simplification of the National Building Code of Canada seismic hazard map for spectral acceleration at a 0.2 second period (5 cycles per second), and shows the ground motions that might damage one- to two-storey buildings. Lopes, A., E. Nezry, R. Touzi, and H. Laur, 1993. The Potential for Earthquakes in the Quebec Utica Shale . The complexity of CSZ seismicity can be explained by a combination of factors. Kempf, P., & Moernaut, J. These systems provide images sufficiently detailed to locate collapsed buildings (Chiroiu and André, 2002; Adams et al., 2003). However, most of the enormous region from the Rockies to the Atlantic . Beneath the St. Lawrence River, however, these structures lie hidden by several kilometres of Appalachian nappes and hundreds of meters of Quaternary sediments. The ortho-image has a final planimetric positioning accuracy of 30 to 40 m. A Gamma adaptive filter (Lopes et al., 1993) is incorporated during the re-sampling process to reduce the SAR speckle. Seismologists often use the term seismic zones to mean areas where the seismicity likely shares a common cause. This zone lies mainly beneath the St. Lawrence River between Ile aux Lievres to the northeast and Ile aux Coudres to the southwest. During the past 30 days, Quebec was shaken by 1 quake of magnitude 4.0, 2 quakes between 3.0 and 4.0, and 16 quakes between 2.0 and 3.0.There were also 29 quakes below magnitude 2.0 which people don't normally feel. by admin. Previous studies of this earthquake concentrated on modeling teismograms recorded at regional distances, a better constrained focal mechanism is obtained. Last month of events located by Earthquakes Canada. In Charlevoix, composite products that include remote sensing imagery reveal a very complex fault distribution (Figure 2). A.L. "This area is quite an active seismic zone in eastern Canada, it's part of what we call the western Quebec seismic zone and in this region, we report one earthquake every five days," she said. Despite these repetitive large earthquakes, no surface rupture has ever been reported in the geological maps, in the historical accounts or in the scientific reports. Earthquake Zones in Canada. An earthquake centred less than 100 kilometres from the nation's capital, in the Western Quebec seismic zone, was felt in both Ottawa and Toronto Friday. A repeat earthquake of the 1663 M~7 earthquake would seriously damage towns located in the epicentral region on both shores of the St. Lawrence River. On November 18, 1929, a submarine earthquake (magnitude 7.2) beneath the Grand Banks south of Newfoundland caused an underwater landslide. At 9:43 a.m., a quake measuring 5.2 on . Found inside – Page 43Several densely populated areas are affected by seismic activity in the northeast, including large urban areas such as Quebec City, Montreal, Ottawa, Toronto, Boston, New York City and Buffalo. Northeastern America is located on a very ... The next day, Tee Lake (close to the epicenter) was clouded. Natural Resources Canada, Ottawa, Ontario, Maurice Lamontagne, Mario Beauchemin, Thierry Toutin, Magnetic and Gravity Methods in Mineral Exploration: the Value of Well-Rounded Geophysical Skills, Knowledge True and False: Scientific Logic and Climate Change, Geomechanics: Bridging the Gap from Geophysics to Engineering in Unconventional Reservoirs, True Depth Conversion: More Than a Pretty Picture. One of these areas is the Charlevoix Seismic Zone (CSZ) of Quebec, one of the most seismically active regions of Canada (Figure 1). The fault on which the Wednesday quake ruptured is part of a larger intraplate system called the Western Quebec Seismic Zone. Because this is the earliest recorded local earthquake, there is little information about it. "In the Western Quebec Seismic Zone, we get about 150 [earthquakes] a year," said Sylvia Hayek, of . State-of-the-art of extraction of elevation data using satellite SAR data, ISPRS Journal of Photogrammetry and Remote Sensing, 55 (1):13-33, http://www.ccrs.nrcan.gc.ca/ccrs/rd/sci_pub/bibpdf/4751.pdf. 1 For more information on the basics of remote sensing, visit: http://www.ccrs.nrcan.gc.ca/ccrs/learn/tutorials/fundam/fundam_e.html. The Western Quebec Seismic Zone is a seismically active area in the Ottawa Valley in Eastern Ontario and Western Quebec.The zone stretches from Montreal to Témiscaming and from Cornwall up along the Laurentian Mountains.. Multi-sources Data Fusion with an Integrated and Unified Geometric Modeling, “EARSeL Journal”, Advances in Remote Sensing, 4,(2): 118- 129. http://www.ccrs.nrcan.gc.ca/ccrs/rd/sci_pub/bibpdf/1223.pdf, Toutin, Th., 1997. Maurice Lamontagne obtained his first degree in Geological Engineering from Université Laval in Québec City. In all likelihood, the current conditions that create CSZ earthquakes may persist for thousands of years in the future.

Had these rates existed over millions of years, evidence of this activity would have been mapped in the field and seen in the seismic reflection profiles. At depth, CSZ earthquakes occur solely in the Precambrian basement from about 5 to 30 km depth, with two thirds between 7 and 15 km. The Western Quebec Seismic Zone (French: Zone sismique de l'Ouest du Québec) is a seismically active area in the Ottawa Valley in Eastern Ontario and Western Quebec.The zone stretches from Montreal to Témiscaming and from Cornwall up along the Laurentian Mountains. September 15, 2021 11.22am EDT. Join our CSEG LinkedIn Group. Between 1977 and 2003, the local seismograph network recorded more than 3000 earthquakes with magnitudes between -1.0 and 5.0. Although seismicity maps and earthquake catalogs show the past 100 to 150 years of felt and instrumental earthquakes, many faults in the United States have return times of thousands to tens of thousands of years for surface faulting events. Consequently, the earthquake activity must be due to inherent crustal weakness and/or high pore fluid pressure. For the damage potential it poses, the seismic hazard of the CSZ is as high as it is in those areas of British Columbia where earthquakes are expected due to plate tectonics. British Columbia, western Alberta. It is cut by faults created during at least four major tectonic events: the Grenvillian collision (1100 to 900 Ma); the rifting episode related to the opening of the Iapetus Ocean (700 Ma); the Taconian reactivation of these faults at the closing of that ocean (450 Ma); and finally, a Devonian meteor impact (350 Ma; Rondot, 1979). please let us know by emailing: Image pro ducts that include remote sensing imagery have helped defining some characteristics of these faults. One of these areas is the Charlevoix Seismic Zone (CSZ) of Quebec, one of the most seismically active regions of Canada (Figure 1). The largest earthquakes known in this part of Canada occurred in 1935 (M6.1), about 250 km (150 . As an outcome of this research, Canadian earthquake hazard maps (Hazard Zones) were developed to support the determination of insurance coverage terms and conditions in Canada. InSAR is also useful in the response phase as ground displacement can correlate with damage in built environments (CEOS, 2001). Pattern of quakes in the area. Contrary to popular belief, Eastern Canada is more at risk of earthquakes than perceived. Value added Radarsat products for geoscientific applications, Can. The whole Pacific northwest coast . Found inside – Page 1313epicentral areas of the 1983 ( magnitude 5 ) Goodnow earthquake in the Adirondack Mountains , and the 1985 ( magnitude 4 ) ...

Friday, September 17th 2021, 10:54 am - A closer look at the complex factors at play, both under and on the Earth's surface, shows that some of the worst earthquake risks are in a zone running . Tweet 0 Share 10 Share 10. For the St. Lawrence valley, the seismic provisions of the upcoming NBCC in 2005 are influenced by the interpretation that a link may exist between CSZ earthquakes and paleo-rift faults. [2], At the epicenter of the 1935 Timiskaming earthquake, cracks in gravel and sand could be seen. In the CSZ, the Precambrian basement outcrops only on the north shore of the St. Lawrence River. 2 ChromaDepth 3-D is a trademark of Chromatek Inc (www.chromatek.com). Article Google Scholar . As an outcome of this research, Canadian earthquake hazard maps (Hazard Zones) were developed to support the determination of insurance coverage terms and conditions in Canada. In 1732 , an earthquake estimated at 5.8 on the Richter scale shook Montreal, causing significant damage. 14, No. For the purposes of calculating probabilistic ground motions for seismic hazard . It was a startling reminder that Central Canada is an earthquake zone. The Western Quebec Seismic Zone (WQSZ) is a 160-km-wide band of intraplate seismicity extending 500 km from the Adirondack Highlands (United States) to the Laurentian uplands (Canada). Earthquakes may occur where rift faults are found along the St. Lawrence valley, despite the current low level of seismic activity (Adams et al., 1996).
