“The Subduction Zone Observatory Takes Shape” The article “The Subduction Zone Observatory Takes Shape” published in Science magazine was written by Julia Rosen. Dr. Rosen has an Honors Degree BS in Geological and Environmental Science from Stanford University and a PhD in Geology from Oregon State University. She is an award-winning writer currently working as a freelance science journalist (cite?). The article discusses the proposal for a new‚ large-scale research program called the Subduction

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

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

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 earthquake

This event is called subduction. The subducting plate carries with it some crust sediments down into the subduction zones. The heat of the mantle melts the edges of the down-turned plate and the sediments it carried. The molten plate is called magma. The magma‚ being light‚ is pushed up against the crust. As it tries to escape to the surface‚ it sometimes creates violent explosions. As it progressed‚ belt of volcanoes were formed on above the dominant plate. When the subduction occurred underwater

GEOLOGY & CIVIL ENGINEERING As living creatures‚ the importance of understanding the earth we live in is paramount for our survival and development. Geology is the “scientific study of the origin‚ history and structure of the earth”. It involves understanding earth’s processes‚ materials and its effects on all forms of life. From earth elements such as rocks and mountains to natural phenomenon such as volcanoes and earthquakes‚ the field of geology encompasses a wide range of concepts fundamental

Verona Teenagers Commit Suicide The bodies of Romeo Montague and Juliet Capulet were found today in the Capulet tomb. Romeo had taken a poison‚ and Juliet stabbed herself with Romeo’s dagger. But the question is why? It all begins with the feuding Montagues and Capulets. Romeo and his friends sneak into a Capulet party‚ where Romeo meets and falls in love with Juliet. With the help of Friar Lawrence‚ who hopes to reconcile the families‚ they are secretly married the next day. Juliet’s

earthquakes happen are on subduction zones where there usually are ocean trenches and oceanic mountain ranges. About 13% of the earthquakes on the map occurred along subduction zones. Out of all of the earthquakes on the map‚ I would say that about twenty of the quakes do not appear to be associated with any active plate boundary. The most powerful earthquakes that were plotted on the map occurred along subduction zones. The deepest earthquakes on the map also occurred along subduction zones. The geological

Creationism is believing that a superior being called‚ God‚ created Earth and all of the living creatures we have‚ such as: humans‚ animals‚ birds‚ and plants. Creationists believe that this God created it using only his words and creating humans with his own hands and breathe of life. Evidence found for creationism has been discredited throughout the years by ‘simple’‚ evolutionary explanations‚ but neither evolutionists or creationist have the closest thing to a proof. The first evidence for

displace the overlying water. It is very unlikely that they can form at constructive or conservative plate boundaries. This is because constructive or conservative boundaries do not generally disturb the vertical displacement of the water column. Subduction zone related earthquakes generate the majority of all tsunamis. Tsunamis have a small wave height offshore‚ and a very long wavelength (often hundreds of kilometers long)‚ which is why they generally pass unnoticed at sea‚ forming only a slight
