It’s hard to give this location a specific latitude, and longitude because it covers a vast amount of land, and that’s why I will just say its in the Gulf of Alaska. A 7.8 magnitude quake struck off the western coast of Haida Gwaii at around 8:10pm Pacific Time on Saturday 27 October 2012. It lies at the northern extremity of the Pacific spreading axis. The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. This area does have a breathtaking mountain landscape, which I would recommend that you come and visit. The P nodal focal mechanism for the 1949 earthquake indicates a virtually pure strike-slip movement with a northwest striking nodal plane corresponding to the strike of the fault. The 1949 Karlıova earthquake occurred at 18:44 UTC on 17 August with an epicenter near Karlıova in Bingöl Province, Eastern Anatolia Region of Turkey. I will tell you! The islands are separated from the mainland to the east by the shallow Hecate Strait. The 1946 Vancouver Island earthquake struck Vancouver Island on the Coast of British Columbia, Canada, on June 23 at 10:15 a.m. with a magnitude estimated at 7.0 Ms and 7.5 Mw. The Queen Charlotte fault is a transform boundary that occurs off the shores of western Canada, but when it is around the shores of Alaska the boundary continues on as the Fairweather fault. Change ). First, at approximately 40 Ma the relative plate motions switched from orthogonal convergence to right-lateral strike slip. The Queen Charlotte fault, often called the ‘San Andreas of the North,’ is a strike-slip plate boundary that separates the Pacific and North American tectonic plates offshore western Canada and Southeast Alaska.

The three largest events were the M7.2 thrust mainshock that struck near the unincorporated community of Petrolia midday on April 25 and two primary strike-slip aftershocks measuring 6.5 and 6.6 that followed early the next morning. Now with all this science going on through my head I was starting to lose it, so I decided to have some local crab. Hope you enjoyed the presentation Any Question or Comments :) Facts The Queen Charlotte Fault is now called the Haida Gwaii. The fault is named for the Queen Charlotte Islands (now Haida Gwaii) which lie just north of the triple junction. The Queen Charlotte Fault is an active transform fault that marks the boundary of the North American and the Pacific Plates.It is Canada's right-lateral strike-slip equivalent to the San Andreas Fault to the south in California.The Queen Charlotte Fault forms a triple junction on its south with the Cascadia subduction zone and the Explorer Ridge (the Queen Charlotte Triple Junction). In the case for the Queen Charlotte-Fairweather fault the Pacific plate is grinding up against the North American plate, while the North American plate is grinding down on the Pacific plate. Moresby Island is a large island that forms part of the Haida Gwaii archipelago in British Columbia, Canada, located at 52.75°N 131.8333333°W. It is named after the explorer of the same name. THE FAULT Queen Charlotte’s fault, named after its located near Queen Charlotte’s Islands in Canada, is a transform fault of approximately 700 km long (see figure 1). The Cascadia subduction zone is a convergent plate boundary that stretches from northern Vancouver Island in Canada to Northern California in the United States. Deep-Sea Research Part II: Topical Studies in Oceanography 104, 83–92. Thank you for reading my third post about boundary types! At 124° 24' 34" W longitude it is the westernmost point on the coast of California. The Explorer Ridge is a mid-ocean ridge, a divergent tectonic plate boundary located about 241 km (150 mi) west of Vancouver Island, British Columbia, Canada. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. CBC Newsworld, "7.7 Magnitude Quake Breaking News Special", airdate: 27–28 October 2012. The study of the Queen Charlotte Fault affords further important information applicable to other similar faults throughout the world. Change ), You are commenting using your Facebook account. The two segments are collectively called the Queen Charlotte-Fairweather Fault System.
