Only a Matter of Time: the Impacts of the Cascadia Subduction Zone And
Running head: ONLY A MATTER OF TIME Only a Matter of Time: The Impacts of the Cascadia Subduction Zone and Colonialism on Indigenous Communities in Vancouver Island Sydney M. Dyck Mount Royal University ONLY A MATTER OF TIME Abstract The Cascadia Subduction Zone is a fault line that runs seven hundred miles off of the coast of the Pacific Northwest, where two borders of tectonic plates meet and have been subducting for centuries (Schulz, 2015). This fault line poses the threat of an impending earthquake and tsunami, as the subduction zone will eventually give way to the enormous amounts of pressure on the undersea plates, triggering what Schulz calls a “seven-hundred-mile liquid wall that will reach the Northwest coast, on average, fifteen minutes after the earthquake begins” (2015). The devastation this earthquake and tsunami duo will unleash upon coastal British Columbia and the Pacific Northwest will inevitably be catastrophic, with approximately 7,000,000 people being at risk of exposure to this disaster and an estimated 71,000 people living directly in the inundation zone (Schulz, 2015). Kenneth Murphy, who directs the Federal Emergency Management Agency’s Region X, the division responsible for Oregon, Washington, Idaho, and Alaska, stated, “Our operating assumption is that everything west of Interstate 5 will be toast;” under this premise it is of utmost importance for us to consider those who are most vulnerable to the risks associated with a disaster of this size (Schulz, 2015). In this paper, I will be focusing on the potential effects that a natural disaster triggered by the Cascadia Subduction Zone could have on those living on Vancouver Island, specifically the Indigenous peoples who have populated the area for centuries. -

SUBMISSION TO THE NUNAVUT WILDLIFE MANAGEMENT BOARD FOR Information: Decision: X Issue: Southampton Island (SHI) Caribou Management Background: • The Southampton Island caribou herd was in decline beginning in June 2003, and by June 2011 had declined to levels unable to sustain the estimated subsistence harvest. • The main cause of the decline was a reproductive disease termed Brucellosis. This disease causes severe reproductive declines within caribou populations, negatively impacting birth rates in females and sperm production in reproductive males through testicular tissue damage. • Though the disease is thought to have caused the decline, intra-territorial sales of caribou meat from SHI to primarily Baffin Communities dramatically accelerated the decline in 2010 and 2011. • The establishment of a TAH helped control this intra-territorial sale, helping to stabilize the population. • Management actions have proven effective thus far but all parties are very concerned about finding a way to control the intra-territorial sale of caribou meat if we are to secure the herds future. Current Status • The SHI caribou population has increased from an estimated 7,287 caribou in May 2013 to 12,297 caribou in May 2015. • Both the Department of Environment (DOE) and the Coral Harbour Hunters and Trappers Organization (HTO) believe this increase is at least in part related to an emigration event detected by Coral Harbour hunters in the winter of 2013/2014 from mainland Nunavut. • DOE is currently comparing genetic profiles of recent caribou samples with pre- immigration samples in an attempt to confirm this immigration event. • Additionally both Coral Harbour harvesters and DOE survey crews have detected an increase in calf observations between the 2012/13 harvesting season and the present suggesting an increase in productivity over the same period. -

Earthquakes in Southwestern British Columbia
Earthquakes in southwestern British Columbia Southwestern British Columbia is one of the most seismically active regions in Canada. Approximately 400 earthquakes occur each year in the region extending from the north end of Vancouver Island to Seattle, Washington U.S. seen on the map below. About a dozen of these earthquakes are felt by people, but many of the larger earthquakes occur offshore. Earthquakes capable of causing structural damage happen every decade or so. What Causes Earthquakes? The surface or crust of the Earth is always moving. Large segments of this crust, called tectonic plates, continually shift against each other, causing stress to build-up. When the stress becomes too great, a sudden rupture or earthquake occurs along a zone of weakness called a fault, generating seismic waves. Earthquakes occur most Maintaining the frequently where tectonic plates interact - such as the Cascadia antennae that receive Subduction Zone of southwestern British Columbia. earthquake data from 15 Years of Earthquakes remote stations. 15 Years of Earthquakes 15 Years of Earthquakes 15 Years of Earthquakes The Cascadia Subduction Zone (CSZ) 50˚ 50˚ Southwestern British Columbia is located above the boundary between the oceanic Juan de Fuca Plate and the continental 50˚ Vancouver North American Plate.
