This results in very rapid uplift rates (mountain building) of up to 30 mm/year. Subduction earthquakes are the rarest and most damaging types of earthquakes, with magnitudes of 8 or larger. There are no areas in B.C. The pur-pose is to combine the requirements from these sources into a single comprehensive document. Seismic hazard varies across the province, covering the entire range from low to high risk. 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. For the purposes of calculating probabilistic ground motions for seismic hazard assessment, seismic zones imply regions on a map which have a common areal rate of seismicity. 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). 0000054199 00000 n It explains those requirements and demonstrates generally accepted construction methods that comply with these requirements. Subduction Zone earth-quake (1:475 years) is not reflected in the NBC maps, and could result in Zone 6 velocities being exceeded on Southern Vancouver Island. �?��� _��kx4�&�O��ʶ�|���YJ�3_hnexk_l!l��Qe� �J1I WZm�, �ߣ�wv��l��}��; 8��i���/c�{|);u�����Om 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.

The project was designed to help nations prepare for future earthquakes and take steps to mitigate potential damage and reduce deaths. Expected ground motion can be calculated on the basis of probability, and the expected ground motions are referred to as seismic hazard. Expected shaking comes from seismic hazard maps National Building Code The minimum standard to protect the life and safety of building occupants and the general public as the building responds to strong ground shaking 1953 One map Primarily a zoning map Peak Acceleration for 4 zones.

This probability is used in the National Building Code to help design and construct buildings that are as earthquake proof as possible. INTRODUCTION In 2003, this study was launched to assess the new information about the relative risk of earthquake damage across Canada. 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.

In the region of moderate hazard, there is a 5 to 15 per cent chance that significant damage will occur every 50 years. Both the Seismic Hazards Mapping Act and the Alquist-Priolo Earthquake Fault Zoning Act require disclosure of seismic hazard zones for prospective purchasers of property located within these zones (§§ 2621.9 & 2693 CPRC). The building that I calculate is located in the North German Plain. Although earthquakes occur in all regions of Canada, certain areas have a higher probability of experiencing damaging ground motions caused by earthquakes. The Global Seismic Hazard Assessment Program was a multi-year project sponsored by the United Nations that assembled the first consistent worldwide map of earthquake zones.. 0000001380 00000 n 0000020159 00000 n The seismic hazard map layer indicates the relative seismic hazard across Canada.
