In areas defined by the dashed outline large-scale changes to natural terrain due to constructionand/or excavation may result in local high slope hazard. Other similar areas may exist elsewherebut have not been noted.

Maps 2 to 4 are simplified versions of the amplification of ground motion, liquefaction and earthquake-induced slope instability maps. These maps have been simplified from Geoscience Maps 2000-3a,3b, and 3c by combining the very low and low ratings and the high and very high ratings to produce a three-class rating system – low, moderate and high.

NOTE:

This map and accompanying information are not intended to be used for site specific evaluation ofproperties. Soil and ground conditions in the map area were interpreted based on borehole data andother information, available prior to the date of publication and obtained from a variety of sources.Conditions and interpretations are subject to change with time as the quantity and quality of availabledata improves. The authors and the Ministry of Energy and Mines are not liable for any claims oractions arising from the use or interpretation of this data and do not warrant its accuracy andreliability.

* Low to high hazard is applied to areas with insufficient data to assign a more specific hazard rating, butthe average hazard rating can be considered moderate in these areas (see also comments on Map 1 referring toareas assigned low to high hazard rating on the slope hazard map).

The relative amplification hazard ratings shown on Maps 1 and 2 are generalized ratings and do not reflect theamplification hazard in all cases. In particular, the amount of amplification due to soil conditions diminishes as thestrength of ground shaking (i.e. acceleration) increases. Maps 5 to 8 show how amplification factors (not the actualamount of earthquake ground motion) can vary with different strengths and periods of ground motion. The variatioin ground motions predicted using the amplification factors shown in Maps 5 to 8 does not exceed the seismic designcriteria of the current building code (National Research Council of Canada, 1995), but could be significant forstructures not governed by the seismic provisions of the code as well as older structures.
