Canada contains 21 active volcanoes. Of these, one of the most remote and scenic volcanoes is located just north of the Iskut River near the border of Alaska. This volcano last erupted in 7050 BC, and will certainly erupt again. The volcano I am referring to is called Hoodoo Mountain, which is an unusual type of volcano called a tuya. This video covers the recent eruptions from this volcano, explain how it formed, and states the general hazard which it poses in the future. This video was made by a geologist who is based in Arizona. Check out this blog for a scientist who spent an extended amount of time at this remote volcano! https://blogs.dickinson.edu/edwardsb/...

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.
