Mount Edziza, a stratovolcano in northwestern British Columbia A topographic map of Canada, showing elevations shaded from green (lower) to brown (higher). Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes ...
The Bridge River Ash is a large geologically recent volcanic ash deposit that spans from southwestern British Columbia to central Alberta, Canada. The ash consists of dust-sized shards ellipsoidal fragments of pumice. It overlaps the Mount St. Helens Yn Ash and the Mazama Ash which were erupted from Mount St. Helens and Mount Mazama about 3,400 ...
The Interagency Volcanic Event Notification Plan (IVENP) was created to outline the notification procedure of some of the main agencies that would be involved in response to an erupting volcano in Canada, an eruption close to the Canada–United States border or any eruption that will have effects in Canada. [38]
List of volcanoes in Canada is an incomplete list of volcanoes found in Mainland Canada, in the Canadian islands and in Canadian waters. All but two provinces , Prince Edward Island and Manitoba , have at least one volcano.
On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash as far away as 200 miles (320 km) to the east. [18] A huge column of volcanic ash and gas rose more than 30,000 feet (9,100 m) into the air and was visible from as far away as Eureka, California, 150 miles (240 km
A Volcanic Ash Advisory Center (VAAC) is a group of experts responsible for coordinating and disseminating information on atmospheric volcanic ash clouds that may endanger aviation. As at 2019, there are nine Volcanic Ash Advisory Centers located around the world, each one focusing on a particular geographical region.
This volcanic ash deposit is estimated 1,890 and 1,250 years old, covering more than 340,000 km 2 (130,000 sq mi) of northwestern Canada and adjacent eastern Alaska. [10] Unproven legends from indigenous people in the area indicate the final eruption from Mount Churchill 1,250 years ago disrupted food supplies and forced them to move further south.
The Mount Edziza volcanic complex is a linear group of volcanoes in northwestern British Columbia, Canada. [8] [9] It is about 65 km (40 mi) long and 20 km (12 mi) wide, consisting of several stratovolcanoes, shield volcanoes, subglacial volcanoes, lava domes and cinder cones.
