The 1949 Queen Charlotte Islands earthquake was caused by a rupture on the Queen Charlotte Fault, which forms part of the boundary between the Pacific and North American plates. Excessive Violence
The fault rupture began in the ocean bottom offshore from Graham Island and spread for more than three hundred miles along the Queen Charlotte Fault. This is the talk page for discussing improvements to the 1949 Queen Charlotte Islands earthquake article. The 1949 Queen Charlotte Islands earthquake struck the sparsely populated Queen Charlotte Islands and the Pacific Northwest coast at 8:01 p.m.wikipedia Reproduction Date: The 1949 Queen Charlotte Islands earthquake struck the sparsely populated Queen Charlotte Islands and the Pacific Northwest coast at 8:01 p.m. PDT on August 21. Prior to the mid-1980s, very little was known about the detailed distribution of earthquakes in this area as there was no local seismograph network to detect and locate small earthquakes. In California the plates are moving at a relative rate of twenty-five miles per million years, mainly related to the San Andreas Fault. Although nobody was killed in this earthquake, people and animals were knocked off their feet and there were landslides and other damage. /* 728x90, created 7/15/08 */

The interplate earthquake began in the ocean bottom just off the rugged coast of Graham Island. But if he promises an annual free stay in a luxury hotel on Earth, hed better have the rooms available.”—Unknown. WHEBN0017743962

Off British Columbia’s coast the rate is thirty miles per million years, almost entirely carried by the Queen Charlotte Fault. The 1949 Queen Charlotte Islands earthquake struck the sparsely populated Queen Charlotte Islands and the Pacific Northwest coast at 8:01 p.m. PDT on August 21. Required fields are marked *. In addition to the 1949 giant earthquake, there have been ten large earthquakes since 1872 with magnitudes between 6.7 and 7.9, all potentially very destructive. Because this quake occurred before the modern Surface wave magnitude scale was developed and widely implemented, this earthquake may have only had the same overall intensity as the 2012 Haida Gwaii earthquake. In Prince Rupert, windows were shattered and buildings swayed. EnviroZine: Environment Canada's Online Newsmagazine Retrieved on 2008-06-03. In the service community of Terrace, away on the mainland, cars were bounced around, and standing on the street was described as "like being on the heaving deck of a ship at sea".

The shaking was so severe that cows on the Queen Charlotte Islands were knocked off their feet. The earthquake ruptured the fault for a distance more than 500 km (311 mi). (adsbygoogle = window.adsbygoogle || []).push({}); Your email address will not be published. Aftershocks as large as 6.3 were reported. In Terrace, on the adjacent mainland, cars were bounced around. 0 Related Articles [filter] No Results Found! From Infogalactic: the planetary knowledge core. Because this quake occurred before the modern surface wave magnitude scale was developed and widely implemented, this earthquake may have only had the same overall intensity as the 2012 Haida Gwaii earthquake. [3] No deaths were reported in this earthquake. The earthquake was felt at Jasper, over six hundred miles away. It is a strike slip fault, similar to the San Andreas of California, and capable of generating equally large earthquakes.

The Queen Charlotte Islands earthquake of 1949 was a magnitude 8.1 interplate earthquake that struck the sparsely populated Queen Charlotte Islands and the Pacific Northwest coast on August 22, 1949.. Large sections of coast were drowned, Indian villages were lost, and a great sea wave or tsunami was observed hours later in Japan. Your email address will not be published. Geometry of the plate boundary in California has changed dramatically as two triple junctions migrated along the coast; the main transform fault has progressively moved inland over the years. Analysis of earthquakes observed on these seismographs has revealed a more extensive earthquake pattern than that associated directly with the Queen Charlotte Fault. This was the biggest quake in Canadian territory since 1949. It ruptured along the Queen Charlotte Fault both northward and southward more than 500 km (311 mi). The Juan de Fuca Plate is a large part of the Pacific Ocean seabed which is slowly moving, driven by tectonic forces deep within the earth, and pushing under the coast of Oregon, Washington, and British Columbia. 1949 Queen Charlotte Islands Earthquake. Current observations of seismic activity and uplift of the coastal regions suggests that another super giant earthquake may be in the making. [3] In the port city of Prince Rupert, windows were destroyed and buildings swung. It occurred on the Queen Charlotte Fault (Canada's equivalent of the San Andreas Fault) - the boundary between the Pacific and North American plates that runs underwater along the west coast of the Haida Gwaii (formerly Queen Charlotte Islands) off the west coast of British Columbia.

The main shock epicenter began in the ocean bottom just offshore of the rugged coast of Graham Island. Fortunately, most of them occurred offshore or in remote regions so there were few deaths and only moderate damage. The 1949 Queen Charlotte Islands earthquake struck the sparsely populated Queen Charlotte Islands and the Pacific Northwest coast at 8:01 p.m.wikipedia. However, the greatest earthquake in Canadian history was the 1700 Cascadia earthquake, a megathrust earthquake that occurred along the Pacific Northwest coast from Northern California to southwestern British Columbia which reached magnitude 9 on the Richter magnitude scale. Canada’s largest earthquake of the past three hundred years, magnitude 8.1, occurred on August 22, 1949 off the coast of British Columbia on the Queen Charlotte Fault, the boundary between the Pacific and North American plates that runs underwater along the west coast of the Queen Charlotte Islands. Chimneys toppled, and an oil tank at an inlet collapsed. This fault runs from northern Vancouver Island, west of the Queen Charlotte Islands, up to the Gulf of Alaska. In particular, considerable seismicity occurs east of the fault, on Graham Island and in Hecate Strait, the ocean region between Graham Island and the Mainland of British Columbia. Shaking was felt throughout British Columbia, parts of Washington, Oregon, Alberta, the Yukon, and Alaska. The shock had a surface wave magnitude of 8.1 and a maximum Mercalli Intensity of VIII (Severe). The shaking was so severe that cows on the Queen Charlotte Islands were knocked off their feet. Because this quake occurred before the modern surface wave magnitude scale was developed and widely implemented, this earthquake may have only had the same overall intensity as the 2012 Haida Gwaii earthquake.

It ruptured along the Queen Charlotte Fault both northward and southward more than 500 km (311 mi). The 1949 earthquake was larger than the 1906 San Francisco earthquake, causing nearly a 500 kilometre long segment of the Queen Charlotte Fault to break.
