Epicenter at 48.117, -71.183 This information is important for relief agencies (rescue teams) that need to quickly locate potential victims and map structures at risk. On land, remote sensing imagery1, mainly radar, is central to our interpretation of geological faults. Thurso D4 quoting a news account. Pub., No. Check your email for your verification email, or enter your email address in the form below to resend the email. InSAR can also contribute to the mitigation phase by adding to the spatial understanding of fault mechanism dynamics and strain, an aspect that could be used in seismically active areas such as the CSZ. Zebker, H.A., Studying the Earth with Interferometric Radar, Computing in Science and Engineering, vol.

Open the windows and leave the premises. at 11:44 October 28, 1997 UTC, Location: (50.2 miles), 2010-06-23 17:41:41 UTC . In Charlevoix, composite products that include remote sensing imagery reveal a very complex fault distribution (Figure 2). Passive remote sensing systems such as SPOT or Landsat record the energy reflected by the Earth’s surface at frequencies roughly equivalent to those detected by our eyes. 3, p. 52-60, 2000. This paper contains a brief account of a number of the larger shocks in eastern Canada. at 10:42 March 14, 1996 UTC, Location: D4 DAWSON, Sir J. W., 1870. (10.2 miles), 1988-01-28 08:38:28 UTC Earthquakes cause damage in the zone about once a decade. Part II-Earthquakes of northeastern United States and eastern Canada: Obs. Québec does have a history of seismic activity, but major earthquakes are rare. Epicenter at 47.67, -69.91 Earthquakes represent a significant natural hazard. Epicenter at 47.0, -76.7 You can take action now to protect you and your family from earthquake hazards. at 18:08 May 17, 1991 UTC, Location: Assoc. Epicenter at 47.75, -69.73 Advance. Landsat images of the region were examined but did not yield any structural information not already described in geological maps. at 12:50 March 16, 1999 UTC, Location: at 07:01 October 19, 1990 UTC, Location: (8.2 miles), 1983-01-17 19:35:51 UTC Almost every chimney was thrown down and I believe there were not more than six left in the whole village. Earthquakes of eastern Canada and Adjacent areas 1534-1927, Géog. 2, 16-22. 19.2 km from The absence of any apparent CSZ surface rupture suggests that the current rates of seismic strain release are geologically recent. We have sent you a confirmation email to {* emailAddressData *}. This is the final account of the earthquake of February 28, 1925. 29.2 km from Québec does have a history of seismic activity, but major earthquakes are rare. Recent earthquakes in Ontario and Quebec: - June 23, 2010 — 5.0 magnitude quake. (55.2 miles), 1996-03-14 10:42:26 UTC A history lesson in tragedy. (18.2 miles), 2000-01-01 11:22:57 UTC Do not light matches or lighters. 7.2 km from Epicenter at 45.5, -74.4 Bull., v. 19, 110-113. Material published in the RECORDER includes views and opinions of the respective contributors, and does not necessarily represent those of the CSEG or its affiliates. Although faults are found throughout the Canadian Shield, for reasons unknown only some are active. Occurring in the Charlevoix–Kamouraska region in Québec , at a probable magnitude of 7, the earthquake was felt over much of eastern North America. Use the telephone only in an emergency. All geographical and geological features are thus more accurately located and plotted on the ortho-rectified image. 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). 35.2 km from Industrial earthquake hazards in eastern Canada: Seismol. His papers described earthquakes in seismic zones of Canada, including Charlevoix, the Lower St.Lawrence and Western Quebec. (13.2 miles), 1982-06-16 11:43:30 UTC Take cover under a piece of heavy furniture and hold on to it. If an Earthquake Occurs . The western Québec seismic zone includes the Ottawa Valley from Montréal to the Témiscamingue region, as … Image pro ducts that include remote sensing imagery have helped defining some characteristics of these faults. 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. Epicenter at 46.98, -66.57 A large volume of data is being converted to make this online archive. La Malbaie The vast majority of earthquakes in eastern Canada are caused by sudden movements along ancient faults associated with the St. Lawrence rift, a structure related to the basins of the Ottawa and Saguenay rivers. 2, no. Shawville One of these areas is the Charlevoix Seismic Zone (CSZ) of Quebec, one of the most seismically active regions of Canada (Figure 1). Otherwise, stand against a wall and use your hands to protect your head and neck. Linking these faults with the earthquake activity is difficult because the earthquakes are deep and little control exists on the fault orientations at depth. (4.2 miles), 1999-03-16 12:50:48 UTC {* signInEmailAddress *} - Oct. 19, 1990 — 5.0 magnitude quake. The three large regional faults, the St-Laurent, South Shore and Charlevoix faults, seem to bound active volumes rather than being active themselves (Figure 3). Cap-Chat A catalogue of destructive earthquakes A.D. 7 to A.D. 1899: Brit. 1. Epicenter at 47.64, -69.959 Join our CSEG LinkedIn Group. 16.2 km from Témiscaming Jonquière H10 HODGSON, E. A.,, 1945. http://mceer.buffalo.edu/publications/resaccom/0304/12_Eguchi.pdf. 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. Natural Geol., new ser., v. 5, 282-289. In addition to damaging buildings in areas where soft soils amplify ground motions, some of these large earthquakes triggered landslides in Charlevoix, the Quebec North Shore, the Saguenay and the St-Maurice river, as far as hundreds of kilometers away. epaper, Digital Access, Subscriber Rewards), please input your Print Newspaper subscription phone number and postal code.
