<P> The Garibaldi Volcanic Belt in southwestern British Columbia is the northern extension of the Cascade Volcanic Arc in the United States (which includes Mount Baker and Mount St. Helens) and contains the most explosive young volcanoes in Canada . It formed as a result of subduction of the Juan de Fuca Plate (a remnant of the much larger Farallon Plate) under the North American Plate along the Cascadia subduction zone . The Garibaldi Volcanic Belt includes the Bridge River Cones, Mount Cayley massif, Mount Fee, Mount Garibaldi, Mount Price, Mount Meager massif, the Squamish Volcanic Field, and more smaller volcanoes . The eruption styles in the belt range from effusive to explosive, with compositions from basalt to rhyolite . Morphologically, centers include calderas, cinder cones, stratovolcanoes and small isolated lava masses . Due to repeated continental and alpine glaciations, many of the volcanic deposits in the belt reflect complex interactions between magma composition, topography, and changing ice configurations . The most recent major catastrophic eruption in the Garibaldi Volcanic Belt was an explosive eruption of the Mount Meager massif about 2,350 years ago . It was similar to the 1980 eruption of Mount St. Helens, sending an ash column about 20 km into the stratosphere . </P> <P> The Chilcotin Group is a north - south range of volcanoes in southern British Columbia running parallel to the Garibaldi Volcanic Belt . The majority of the eruptions in this belt happened either 6--10 million years ago (Miocene) or 2--3 million years ago (Pliocene), although with some slightly more recent eruptions (in the Pleistocene). It is thought to have formed as a result of back - arc extension behind the Cascadia subduction zone . Volcanoes in this belt include Mount Noel, the Clisbako Caldera Complex, Lightning Peak, Black Dome Mountain, and many lava flows . </P> <P> The Anahim Volcanic Belt is a line of volcanoes stretching from just north of Vancouver Island to near Quesnel, British Columbia . These volcanoes were formed 8 to 1 million years ago, and the Nazko Cone last erupted only 7,200 years ago . The volcanoes generally get younger moving from the coast to the interior . These volcanoes are thought to have formed as a result of the North American Plate sliding westward over a small hotspot, called the Anahim hotspot . The hotspot is considered similar to the one feeding the Hawaiian Islands . The belt is defined by three large shield volcanoes (Rainbow, Ilgachuz and the Itcha Ranges) and 37 Quaternary basalt centers . </P> <P> Eruptions of basaltic to rhyolitic volcanoes and hypabyssal rocks of the Alert Bay Volcanic Belt in northern Vancouver Island are probably linked with the subducted margin flanked by the Explorer and Juan de Fuca Plates at the Cascadia subduction zone . It appears to have been active during the Pliocene and Pleistocene . However, no Holocene eruptions are known, and volcanic activity in the belt has likely ceased . </P>
