Technician support for A. Dallimore 2018 Research Project and Outreach Project Activities

Dr. Dallimore was awarded Research and Professional Development for a collaborative research project exploring the Cascadia Subduction Zone to accurately interpret earthquakes along the coast.

In order to regionally extend the paleo-seismic inlets work from our main study site at Effingham Inlet, southern Vancouver Island, to the northern terminus of the Cascadia Subduction Zone (CSZ), Royal Roads University (RRU) and Natural Resources Canada collaboratively undertook Natural Sciences and Engineering Research Council of Canada (NSERC) funded coring cruises on the Canadian Coast Guard ship Vector to every inlet along western Vancouver Island. We have raised ten piston cores of marine sediments, which collectively represent a sedimentary record of the full Canadian portion of the CSZ, and in places gives a record of major earthquakes going back about 8,000 years. In Sept. 2016 and 2017, with the support of the Internal Grant for Research (IGR)16 and IGR17 grants, we took the RRU research boat, to several of these core sites , to perform site specific characterization including nearshore multi-beam imagery, sub-bottom profiling and oceanographic water property surveys. This work is required to accurately interpret the return rate of M8-9 CSZ earthquakes along the BC coast, from our modern surveys combined with the 10,000 year old marine sediment records. This research project has also involved annual NSERC PromoScience funded coastal community outreach projects.
