![]() In the region of moderate hazard, there is a 5 to 15 per cent chance that significant damage will occur every 50 years. The probability of strong shaking (strong enough to cause significant damage in a fraction of these buildings) is more than 30 times greater in the regions of highest hazard (at least a 30 per cent chance of significant damage within towns of these regions every 50 years) than in the regions of lowest hazard (less than 1 per cent chance in 50 years). 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. The seismic hazard map layer indicates the relative seismic hazard across Canada. Expected ground motion can be calculated on the basis of probability, and the expected ground motions are referred to as seismic hazard. The latest available quake and fault data is turned ON by default and. The damage potential of an earthquake is determined by how the ground moves and how the buildings within the affected region are constructed. A live map of the latest earthquakes in Orange County and active earthquake faults. This map shows the relative seismic hazard across Canada for single family dwellings (1-2 story structures). However, in the new study, the estimate for the likelihood that California will experience a magnitude 8 or larger earthquake in the next 30 years has increased from about 4.7 for UCERF2 to about 7.0 for UCERF3. Data is provided by the United States Geological Survey. The map below provides an idea of the likelihood of experiencing strong earthquake shaking at various locations across the country. The expected frequency of such events statewide has dropped from an average of one per 4.8 years to about one per 6.3 years. Track the latest minor and major earthquakes in California and around the globe with this interactive map. This probability is used in the National Building Code to help design and construct buildings that are as earthquake proof as possible.

Simplified seismic hazard map for Canada, the provinces and territoriesĪlthough earthquakes occur in all regions of Canada, certain areas have a higher probability of experiencing damaging ground motions caused by earthquakes.
