What is the closest volcano to vancouver, bc
Stratovolcanoes like Mount Garibaldi, north of Vancouver, B.C. and Mount St. Helens in Washington State alternate explosive and dome-building eruptions, and may remain dormant for thousands of years.olcanic eruptions are driven, in part, by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne. When magma erupts, it is called lava. The type of volcano that forms depends on whether the lava is viscous (thick and sticky) or runny, and on how much gas it contains.
