Abstract: 

I compare loss estimates for a range of earthquake scenarios and built environment models for municipalities in Greater Victoria, British Columbia, Canada, using Hazards United States Multi-Hazard version 2.1 (HAZUS) software. Best-estimate losses use region-specific site-condition maps and built-environment inventories updated with municipal assessment information for five scenarios representing subduction-interface, shallow-crustal, and in-slab earthquake types. Losses are higher for a major, near-source, shallow-crustal event than for larger magnitude, great subduction-interface earthquakes. Loss estimates differ by two to three orders of magnitude depending on the source scenario. Site-condition mapping and built-environment updates also significantly affect loss estimates (differences of up to 600% and 450%, respectively), depending on the scenario and loss metric under consideration.
