| Abstract | Based on recently collected seismic-reflection survey data, the western extent of the active Devils Mountain Fault where it meets the Leech River Fault has been mapped for the first time, just offshore
of the cities of Victoria and Esquimalt, British Columbia. This combined approximately 180 km long fault has now been mapped from the interior of Washington State, USA onto southern Vancouver Island, BC, Canada. The occurrence of such an active fault
zone poses a high possibility of a significant crustal earthquake occurring near the cities of Victoria and Esquimalt. |
| Summary | (Plain Language Summary, not published)
Based on recently collected sub-surface survey data, the western extent of the active Devils Mountain Fault has been mapped for the first time, just
offshore of the cities of Victoria and Esquimalt, British Columbia. This approximately 180 km long fault has been mapped from the interior of Washington State, USA onto southern Vancouver Island, BC, Canada. The occurrence of such an active fault
poses a high possibility of a significant crustal earthquake occurring near the cities of Victoria and Esquimalt. |
