At least seven

At least seven eruptions have occurred in the Iskut-Unuk River volcanic field in the past 10,000 years. Since around 1600 all eruptions have occurred at The Volcano.[1] Its total eruption volume is estimated to be 2.2 km3 (0.53 cu mi). Future eruptions from The Volcano will probably be similar in character to those that have occurred throughout its 360-year eruptive history.[4] There is a one in 200 chance per year of an eruption occurring in Canada and one in 220 chance per year of an effusive eruption.[20] An eruption in the foreseeable future is probably more likely along the Northern Cordilleran Volcanic Province than in an unrelated volcanic zone outside the province. This is because the Northern Cordilleran Volcanic Province, which includes the Iskut-Unuk River Cones, is the most active volcanic zone in Canada.[3][4]
