Faults in the valleys near Ottawa could rupture and produce strong, shallow earthquakes. This magnitude 5.5 scenario visualizes the effects of such an event. It does not represent the most severe earthquake that could occur, but one that is more likely and could still cause damage.

In 1997, a magnitude 4.6 earthquake occurred 3 to 4 km beneath the Strait of Georgia. This scenario visualizes the effects of that event if it had a magnitude of 7.0, and represents a strong ground shaking event that could strike Metro Vancouver.

Full rupture of the Cascadia interface fault, the fault defining the boundary between the North American and Pacific Ocean plates. This magnitude 9.0 event, often referred to as ‘The Big One’, affects most communities in southwestern British Columbia.

The Denali Fault spans over 200km of the Yukon Territory, and is a significant source of seismic hazard. This magnitude 7.4 earthquake scenario, centered near small communities along the Alaska Highway, visualizes the effects of a severe earthquake that could be produced by this fault.

In 1997, a magnitude 4.6 earthquake occurred 3 to 4 km beneath the Strait of Georgia, near Vancouver. This scenario visualizes the effects of that event if it occurred today with a magnitude of 4.9. A magnitude 7.0 Georgia Strait scenario is also provided, and represents a less likely but more...

Full rupture of the Leech River Fault, a fault that cuts southern Vancouver Island and extends beneath Greater Victoria. Based on current science, this magnitude 7.3 earthquake scenario represents the strongest ground shaking event that could strike the region, and is one of Greater Victoria’s...

The Probabilistic Seismic Risk Model for Canada introduces a structured framework of indicators that profile the physical, social and economic dimensions of earthquake risk at the neighborhood scale. Risk metrics include measures of building damage and collapse probability, life safety and...

Land cover information is necessary for a large range of environmental applications related to climate impacts and adaption, emergency response, wildlife habitat, etc. In Canada, a 2008 user survey indicated that the most practical land cover data is provided in a nationwide 30 m spatial...

This collection is a legacy product that is no longer supported. It may not meet current government standards. The Canadian Digital Elevation Model (CDEM) is part of Natural Resources Canada's altimetry system designed to better meet the users' needs for elevation data and products. The CDEM...

Compilation by start date of 7-day exposure periods, of the number of spruce budworm larvae exposed that were recovered and either reared to adult or received a parasitism diagnostic. Data linked to scientific paper: Martel V, Régnière J & Therrien P. (2023) Competition between Tranosema...

Data represents surface water occurrence frequency (percentage), which describes the frequency for each grid appeared as water in the 30 years time period of 1991 to 2020. The data covers Canada’s entire landmass including all transboundary watersheds, and is at 30-meter spatial resolution. The...

The transport features of the CanVec series are derived from the National Road Network (NRN) and the National Railway Network (NRWN). The dataset describes roads, trails, bridges, railroads and their related information. The transport features include nautical facilities, track segments, track...

The land features of the CanVec series contains landscape features of Canada such as islands, shoreline delineation, wooded areas, saturated soil features, landform features (esker, sand, etc.). The CanVec multiscale series is available as prepackaged downloadable files and by user-defined...

The hydrographic features of the CanVec series include watercourses, water linear flow segments, hydrographic obstacles (falls, rapids, etc.), waterbodies (lakes, watercourses, etc.), permanent snow and ice features, water wells and springs. The Hydrographic features theme provides quality...

The toponymic features of the CanVec series include proper nouns designating places and representations of the territory. This data come from provincial, territorial and Canadian toponymic databases. They are used in the CanVec Series for cartographic reference purposes and vary according to the...

The elevation features of the CanVec series include the elevation contours and elevation points. These entities are used to describe the relief of the Canadian Landmass. The CanVec multiscale series is available as prepackaged downloadable files and by user-defined extent via a Geospatial data...

The resource management features of the CanVec series include power lines, communication lines, pipelines, valves, petroleum wells, wind-operated devices, transformer stations, ore extraction sites, aggregate extraction sites, peat extraction sites and oil and gas sites. The CanVec multiscale...

The manmade features of the CanVec series include dams, protection structures (breakwater, dike/levees), liquid storage facilities (basin, swimming pool, etc.), tanks, buildings, delimiting structures (fence, walls, etc.), landmark features (cross, radar, crane, forts, etc.), chimneys, towers,...

“Automatically Extracted Buildings” is a raw digital product in vector format created by NRCan. It consists of a single topographical feature class that delineates polygonal building footprints automatically extracted from airborne Lidar data, high-resolution optical imagery or other sources.
