Mount Garibaldi is one of the eleven Canadian volcanoes most strongly associated with recent seismic activity and is located in the Sea to Sky Country of British Columbia, 80 km (50 mi) north of Vancouver, Canada.
Mount Cayley is another one of the eleven Canadian volcanoes associated with recent seismic activity
The long history of volcanism in the area, coupled with continued subduction off the British Columbia Coast, indicates that volcanism has not yet concluded in the area
Many towns and cities near Mount Cayley are home to well over half of British Columbia's human population, and there is a likelihood that future eruptions will cause damage to populated areas, making Mount Cayley and other Garibaldi belt volcanoes a major hazard.
