I experienced my first magnitude 7.0-7.5 earthquake when I was 22 months old. It almost knocked me to the ground. That 1946 Vancouver Island earthquake struck Vancouver Island on June 23, 1946 at 10:15 a.m. with a magnitude estimated at 7.0 Ms and 7.5 Mw. The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon, to Prince Rupert, British Columbia. There were a whole series of landslides in the Forbidden Plateau area that blocked streams and rivers to create lakes. The first hikers into the area gave them great names, Landslide Lake, Rock Fall Lake, Earthquake Lake etc.; over time these natural dams were eroded to nothing, leaving nothing but fading memories of those lakes. This earthquake is Canada's largest historic onshore earthquake. Canada has only been around for 155 years Three years later, an earthquake, an M8.1, struck at 8:01 p.m. PDT on August 2, 1949 in Haida Gwaii [formerly Queen Charlotte Islands], an interplate earthquake that occurred on the ocean bottom just off the west coast of the main south island. The shock had a surface wave magnitude of 8.1 and a maximum Mercalli Intensity of VIII (Severe).

The Active Volcano in Canada; Mount Meager

 


The Active Volcano in Canada; Mount Meager

https://youtu.be/GDstNmXemhI [4:25 minutes]

19,291 views • Apr 8, 2021 • Within Canada is a volcano that relatively recently produced an eruption comparable in size to the 1980 eruption of Mount Saint Helens. The volcano in question is known as Mount Meager, which is still relatively active today as evidenced by its hot springs and fumaroles. This video covers the recent eruptions from this volcano, including its 410 BC Eruption, and states the general hazard which it poses in the future.

Bute Inlet Landslide: The Extended Cut Come with us into a helicopter as it flies over this landscape-altering event.

 


Map of Bute Inlet showing landslide location in Elliot Creek
Map by Josh Silberg

In the early morning hours of November 28, 2020, a chunk of mountain broke free and slid into a glacial lake in a remote part of the British Columbia coast 110 kilometers northeast of Campbell River. The amount of rock that fell into the lake could fill BC Place stadium five times, and triggered a 100-meter-high tsunami that ripped through Elliot Creek.

The landslide and video clips of the resulting destruction made headlines in numerous news outlets. While video snippets gave some sense of the scene, our Hakai Institute team filmed the entire 50-minute helicopter flight along what’s left of Elliot Creek, up to the lake and glacier, and back down to where Elliot Creek meets the Southgate River that flows into Bute Inlet. A map in the bottom left references the location of the helicopter during the corresponding video.

This video from December 17 represents an early snapshot of the emerging story of the massive landslide, its causes, and its fallout. The consequences of the landslide will take time to untangle, but initial concerns have concentrated on the impacts on Elliot Creek and the Southgate River as a salmon-bearing waterways, as well as how the event affected ocean conditions in Bute Inlet.

The landslide occurred on the traditional territory of the Homalco First Nation, and we are working closely with them and other partners to understand this event.

Stay tuned for much more news and science to follow as we analyze the consequences of this enormous event.

NOPE !, SILLY BOY ! Climate change could wake up Canada's dormant volcanoes - Climate Change

All science STOPS when you say Climate Change.  "Climate change could wake up Canada's dormant volcanoes".  Climate change?, balderdash.

You would think that scientists would follow scientific methods; not jump to irrational, UNSCIENTIFIC spectacular conclusions ~ cause célèbre from some reality TV show whose fame will not even lasted the proverbial 15 minutes?  Everything, but everything today is blamed on human caused Climate change?, balderdash.  Does that make sense to anyone, at all.

CBC News: The National

Scientists at Simon Fraser University argue that climate change is destabilizing volcanoes around the world, and they're using a British Columbia mountain range to prove their theory. Not far from Whistler, Mount Meager shows signs of dangerous things to come, which has researchers keeping a very close eye on it.

Mount Meager Landslide

Further images and references, below 

On August 6, 2010 a massive lahar cascaded down from Capricorn Glacier at a speed of 30 m (98 ft) per second. Experts initially estimated that the volume of debris totaled 40,000,000 m3++ [cubic metres] = (1.4×109++ cu ft) which would make it the largest landslide on record in Canadian history.  The record was previously held by the 1965 Hope Slide that removed 47,000,000 m3 (1.7×109 cu ft) of rock from Johnson Peak. However the Meager landslide was later estimated to be more than 48,500,000 m3 (1.71×109 cu ft), making it the largest landslide in Canada's short 155 year history.  [Canada became a country on July 1, 1867].  The first seismograph (one of the first in the world) was built in Victoria in 1898, recording its first earthquake eight days later. This seismograph was operated by Francis Denison of the Meteorological Service of Canada, who recorded and described the M 7 earthquake on December 6, 1918 on the west coast of Vancouver Island.

The 2010 landslide at Mount Meager was 300 m (980 ft) wide and 2 km (1.2 mi) long, creating a dam across Meager Creek and the Lillooet River. This resulted in the creation of a lake just upstream. Early concerns that the dam might collapse and flood the Lillooet River valley ended a day later, when part of the dam ruptured and slowly released the accumulated water. An evacuation alert was rescinded, and nearly 1,500 residents were allowed to return to their homes on the weekend after the landslide occurred. No injuries were reported.

    The 2010 Mount Meager landslide was a large catastrophic debris avalanche that occurred in southwestern British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7). More than 45,000,000 m (1.6×10 cu ft) of debris slid down Mount Meager, temporarily blocking Meager Creek and destroying local bridges, roads and equipment. It was one of the largest landslides in Canadian history and one of over 20 landslides to have occurred from the Mount Meager massif in the last 10,000 years.

    Mount Meager Massif©


    As with Kulshan Stratovolcano© /Mount Baker Stratovolcano©, Mount Meager Massif© is related to where the westward moving North America Tectonic Plate collides with, and rises above the eastward moving Explorer and Juan de Fuca Tectonic Plates. The 7th vent of the volcano blew north, into the Bridge River Valley. The Goldbridge Golf Course is largely talus.

    The Mount Meager massif as seen from the east near Pemberton. Summits left to right are Capricorn Mountain, Mount Meager and Plinth Peak.
    The Mount Meager massif is a group of volcanic peaks in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. Part of the Cascade Volcanic Arc of western North America, it is located 150 km (93 mi) north of Vancouver at the northern end of the Pemberton Valley and reaches a maximum elevation of 2,680 m (8,790 ft). The massif is capped by several eroded volcanic edifices, including lava domes, volcanic plugs and overlapping piles of lava flows; these form at least six major summits including Mount Meager which is the second highest of the massif.
    The Garibaldi Volcanic Belt (GVB) has a long history of eruptions and poses a threat to the surrounding region. Any volcanic hazard ranging from landslides to eruptions could pose a significant risk to humans and wildlife. Although the massif has not erupted for more than 2,000 years, it could produce a major eruption; if this were to happen, relief efforts would be quickly organized. Teams such as the Interagency Volcanic Event Notification Plan (IVENP) are prepared to notify people threatened by volcanic eruptions in Canada.
    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. Evidence for more recent volcanic activity has been documented at the volcano, such as hot springs and earthquakes. The Mount Meager massif has also been the source of several large landslides in the past, including a massive debris flow in 2010 that swept down Meager Creek and the Lillooet River.
