California to Vancouver Island‚ Canada‚ the Cascadia Subduction Zone is a 1000 km long fault line that exists between the North American continental and Juan de Fuca oceanic plates. The danger of the this tremendous fault line is that the Juan De Fuca plate is being forced into the western side of the North American tectonic plate. Instead of sliding underneath‚ the Juan de Fuca has been stuck‚ forcing itself into the side of North America. This subduction zone is an interesting topic to me because an

Cascadia Subduction Zone: A Summary of History Marcellina MacArthur Washington State University Abstract Research shows that there is a pattern of quakes that range from 8.7 to 9.2 that occur every 240 years or so‚ and we know this because Oregon State University has done a 13 year study on the margin stretching from southern Vancouver Island to the Oregon-California border. The last mega-earthquake in the Pacific-Northwest being on January 26‚ 1700; We know this because written

Q: Why is Living on the West Coast of B.C. Dangerous? The west coast of B.C. is an extremely hazardous place to live in because it is located near the Cascadia Subduction Zone‚ a known producer of megathrust earthquakes. Once the earthquake strikes‚ the primary effects will leave the cities located on the coast in ruins‚ but the secondary effects are the main antagonists in the story; victims will have to struggle with fires‚ food shortages‚ and panicking citizens. Fires that were

danger‚ but it hasn’t erupted in a very long time. The last eruption was in 8051 BC. Mount Garibaldi began erupting about 250‚000 years ago and has grown steadily since then. Like most of the Cascade volcanoes‚ it has its own origins in the Cascadia subduction zone; a long convergent plate boundary that stretches from mid- Vancouver Island to Northern California. The first European to see the mountain in 1792‚ Captain George Vancouver‚ traded with the local natives in the area. When skiing became popular

Earthquakes and Subduction Zones Lab Amy Paret Mrs. Igo 9th Grade Periods 3 and 4 Even Date: 2/14/13 Background Research: This lab uses earthquake data to construct profiles of two convergent boundaries: the Tonga Trench and the Peru-Chile Trench. Where two tectonic plates converge‚ if one or both of the plates is an oceanic lithosphere‚ a subduction zone will form. When crust is formed at a mid-ocean ridge‚ it is hot and buoyant meaning it has a low density. As it spreads away from the ridge and

Why did relations between the soviet union and the US change in the years 1943-1956? The first reason is that Roosevelt’s death in April 1945 brought an end to any superficial unity that still existed at the end of World War 2 in 1943. Truman was now the American President‚ and relations between him and Stalin were deteriorating very quickly indeed‚ especially when Stalin was such a determined character and Truman was less willing to compromise‚ compared to Roosevelt. The second reason is

Neritic zone is also called coastal waters‚ the coastal ocean‚ and the sublittoral zone. It is the part of the ocean extending from the low tide mark to the edge of the continental shelf. It is considered a shallow depth‚ extending to about 200 meters. The Neritic zone has decently well oxygenated water‚ low water pressure‚ and fairly stable temperature and salinity levels. This is the location of most of the sea life in the ocean. Salinity is the level of salt in the water. The Neritic zone has a
