The Mount Meager massif produced the largest volcanic eruption in Canada in the last 10,000 years. About 2,400 years ago, an explosive eruption formed a volcanic crater on its northeastern flank and sent avalanches of hot ash, rock fragments and volcanic gases down the northern flank of the volcano.

Has there ever been a volcanic eruption in Canada?
Volcanoes may seem to be non-existent in Canada. There has been only one documented volcanic eruption in Canada in more-recent historical times, but there are many dormant volcanoes in western Canada, particularly in northwestern British Columbia.
When was the last time a volcano erupted in Canada?
The most recent eruption in Canada took place at Lava Fork in northwestern B.C. about 150 years ago. The last big explosive eruption in Canada took place 2350 years ago at Mount Meager, and the ash layer from this eruption can still be found as far away as Alberta.
Is there a supervolcano in Canada?
The Blake River Megacaldera Complex is considered a supervolcano due to its great size and its multiple dikes and vents.
Where are the 5 super volcanoes?
Volcanoes that have produced exceedingly voluminous pyroclastic eruptions and formed large calderas in the past 2 million years include Yellowstone in northwest Wyoming, Long Valley in eastern California, Toba in Indonesia, and Taupo in New Zealand.
What is the largest supervolcano on Earth?
The biggest supervolcano on Earth was discovered in 2013: the Tamu Massif, with a 4 km height and a 640 km width, a submarine shield volcano located in the Pacific Ocean, east of Japan.
Would Canada be affected if Yellowstone erupted?
This would result in a global cooling event that could last for many years, or possibly decades after the eruption. Gilchrist believes it is difficult to imagine that any nation, including Canada, could possibly be ready for a global catastrophe like the eruption of Yellowstone.
Are there underwater volcanoes in Canada?
Bowie Seamount is a large submarine volcano in the northeastern Pacific Ocean, located 180 km (110 mi) west of Haida Gwaii, British Columbia, Canada. The seamount is also known as Bowie Bank.
How many volcanoes are in the Canada?
Canada has 24 Holocene volcanoes.
Is the oldest volcano still active?
The oldest volcano in the chain is the inactive volcano Meiji, which is 85 million years old. So to answer your original question, volcanoes have been erupting on Earth for at least the last 4 billion years and were undoubtedly more active in the distant past than they are today.
What volcano hasn’t erupted in years?
Examples of dormant volcanoes are Mount Kilimanjaro, Tanzania, Africa and Mount Fuji in Japan. Extinct → Extinct volcanoes are those which have not erupted in human history. Examples of extinct volcanoes are Mount Thielsen in Oregon in the US and Mount Slemish in Co. Antrim.
Is there a volcano in Ontario?
The Marmora volcanic ash beds lie within Ordovician limestone rock, located immediately west of the town of Marmora. The ash beds formed about 450 million years ago when volcanoes, in a volcanic arc that formed above subducted ocean crust that floored the Iapetus ocean.
What if Yellowstone went off?
If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants.
Is Yellowstone volcano overdue?
Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. Even so, the math doesn’t work out for the volcano to be “overdue” for an eruption.
Why there is no volcano in Canada?
Because volcanoes in Western and Northern Canada are in relatively remote and sparsely populated areas and their activity is less frequent than with other volcanoes around the Pacific Ocean, Canada is commonly thought to occupy a gap in the Ring of Fire between the volcanoes of the western United States to the south
Where do 75% of the Earth’s volcanoes erupt?
The Ring of Fire is home to 75% of the world’s volcanoes and 90% of its earthquakes.
Is there a volcano bigger than Yellowstone?
Nestled in the San Juan Mountains, there is ample evidence of one of the largest known volcanic eruptions on the planet: a caldera 22 miles wide and 62 miles long. It’s called the La Garita Caldera, and it rivals the Toba eruption in Indonesia and all Yellowstone eruptions.
Where are 75% of the worlds volcanoes found?
the Ring of Fire
Seventy-five percent of Earth’s volcanoes—more than 450 volcanoes—are located along the Ring of Fire.
How old is the oldest supervolcano?
