Is Mount Baker a hazard for Canada?
Although there are several potentially active volcanoes in southwest British Columbia, Mount Baker, 23 km south of the Canada – United States border in Washington state, is the closest volcano to the population centres of British Columbia’s Lower Mainland and Vancouver Island. On a clear day, the ice-covered peak of Mount Baker, 3286 m high, is prominent on the horizon of southwest British Columbia.
Mount Baker is a stratovolcano, constructed over many thousands of years from a mixture of lava and volcanic debris. Like other stratovolcanoes, it has the potential for both explosive and non-explosive eruptions. Mount Baker also has the potential for landslides, debris flows, and lahars (volcanic mudflows and debris flows) because it possesses steep terrain, fractures, and a groundwater system, and is built of rock weakened by hot water and steam.
