Ring of Fire of space weather, earthquakes, tsunamis, volcanoes, and landslides. British Columbia and Yukon are home to a vast region of volcanoes and volcanic activity in the Pacific Ring of Fire. Several mountains in populated areas of British Columbia are dormant volcanoes. Most of these were active during the Pleistocene and Holocene epochs. Although none of Canada's volcanoes are currently erupting, several volcanoes, volcanic fields, and volcanic centers are considered potentially active. Hot springs are at some volcanoes, while 10 volcanoes in British Columbia appear related to seismic activity since 1975, including: the Silverthrone Caldera, Mount Meager massif, Wells Gray-Clearwater volcanic field,
Circum-Superior Belt has been suggested for magmatism of the 2,215 million-year-old Nipissing sills as well, which the Ungava dike swarm could have transported magma to the Nipissing sills area. Before 2003, all magmatism of the Circum-Superior Belt was thought to only occur along the outer margin of the Superior craton. However, the Pickle Crow dike was discovered in 2003 in the interior of the Superior craton and it has since been recognized as a magmatic event related to the Circum-Superior Belt. The dike is dated to 1,880 million years old and associated dikes are traced for at least . These dikes likely
