A map to show location of the event and description a fact file – key facts about the event or volcano (e.g. The height of the tsunami caused by the 2006 eruption. It’s long been known that in the early Cenozoic Era – around 60 million years ago – there were two major tectonic plates, called Kula and Farallon, in the Pacific Ocean off the western coast of North America. a plate boundary map – ensure plates are identified and named; a plate boundary diagram and explanation; a write-up of the effects on people (short and long term) a write-up of the effects on the environment (short and long term) any benefits or opportunities ; the immediate response to the event – include relief from other countries The team’s model suggests that the Yukon slab gradually made its way northeast after the Resurrection plate was first subducted some 40 million years ago. Plate tectonics, theory dealing with the dynamics of Earth’s outer shell that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface … When plates push against each other, one of them will often end up sliding underneath the other, sinking down into the mantle – a process called subduction. Superimposed in red are the more than 400 National Park System sites. Dormant: Resting but which may erupt again in the future. When the volcano first showed signs of erupting. What can be done to reduce the risk of volcanoes? “We believe we have direct evidence that the Resurrection plate existed,” says Spencer Fuston, co-author of the study. Like the scientists before us, we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics. Population and economic development patterns, Unit 2: Global climate—vulnerability and resilience, Unit 3: Global resource consumption and security, 2: Impacts of changing trends in resource consumption, 3. And now, the geologists on the new study say they’ve found this missing plate. But debate has raged about whether they were joined by a third, oddly named Resurrection, which would have since sunk beneath the surface. The team used a method called slab unfolding, which allows them to work backwards from the remains of a subducted plate and work out what it looked like on the surface, millions of years ago, A diagram of the original locations and shapes of the tectonic plates in the Pacific Ocean, off the western coast of North America. The amount of damage done by an earthquake will depend on: Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. longer term responses to the event including measures taken to reduce the risk in the future. Great, just what we need, an older asubduction zone right where we have a new subduction zone where the Juan De Fuca plate is being forced below the North American Plate. Using this method, the team mapped out several large chunks of rock, and worked backwards to identify the original plates they came from. Theory of Plate Tectonics. Volcanoes are categorized in many different ways. Shaded relief map of the U.S. highlighting different tectonic settings. Plate tectonics reveals that the lithosphere is divided into eight major pieces ("plates") with several smaller plates (Fig. What is Plate Tectonics? A 3D block diagram across North America showing a mantle tomography image reveals the Slab Unfolding method used to flatten the Farallon tectonic plate… Some of the worksheets below are Tectonic Plates Worksheets, predicting tectonic activity, definition of plate composition, plate movement, types of plate boundary, continent-continent collision, hands-on activities, … with colorful diagrams along … Interactions between oceans and coastal places, 1. How to make a website: Tools and experiences, 2. The main ones are: Create an information leaflet with labelled diagrams explaining the difference between: Using pages 99 - 101 of your textbook 'Complete Geography for Cambridge IGCSE' identify and explain (create a MindMap): Richter scale and how much energy is released. type) – provide place specific detail, a plate boundary map – ensure plates are identified and named, a write-up of the effects on people (short and long term), a write-up of the effects on the environment (short and long term), the immediate response to the event – include relief from other countries. Now, geologists at the University of Houston claim to have found the remains of an ancient tectonic plate beneath Canada that was pushed under the surface tens of millions of years ago. The population of Montserrat before the volcano erupted. See the stories that matter in your inbox every morning. 2). The name of the hills in which the volcano is situated. No wonder why we get such enormous subduction quakes in that area on a regular basis. A diagram of the original locations and shapes of the tectonic plates in the Pacific Ocean, off the western coast of North America. Create a detailed case study of 2011 Japan Earthquake and Tsunami. The depth of the focus - shallower earthquakes are typically more damaging, The density of population living in the area affected, How the structures have been built - anti seismic structures are more resistant, The type of bedrock - clay and sand are prone to liquifaction, Outline what hazards earthquakes can cause (building collapse, liquifaction, tsunamis etc - list with brief description), Seperate the hazards into primary and secondary, What methods are available to reduce their impact (anti seismic structures, hazard mapping etc), A map to show location of the event and description a fact file – key facts about the event - provide place specific detail. Why do people continue to live in volcanically active areas? The name of the capital city that was evacuated. But intriguingly, the team identified a third slab detached from the others, about 400 to 600 km (250 to 370 miles) below the surface of northern Canada. Plate Tectonics Articles, Theory, Plate Diagrams, Maps, Teaching Ideas. The Resurrection plate's … The plates are mobile, moving in constant, slow motion measured in rates of centimeters per year. Plate tectonics is a theory about how Earth's lithosphere is divided into a series of rigid plates; and, how movements of these plates produce earthquakes, volcanoes, ocean … Michael has always been fascinated by space, technology, dinosaurs, and the weirder mysteries of the universe. Next, they applied a technique called slab unfolding, which can identify subducted plates, then unfold and stretch them to roughly figure out their original shapes. The research was published in the Geological Society of America Bulletin. Letter codes are abbreviations for parks on Tectonic Settings pages and the Tectonic Settings—Master List on the Plate Tectonics … With a Bachelor of Arts in Professional Writing and several years experience under his belt, he joined New Atlas as a staff writer in 2016. Two of the objects they studied are already known – the Alaska and Cascadia slabs, which are still attached to each other. Different types of plate boundary (movement). Patterns in Environmental Quality and Sustainability, Hazards and disasters - risk assessment and response, Environmental Risks of Economic development, Note: How active a volcano is largely depends on where it is found in the world. The amount of aid given by the UK government. The Resurrection plate's existence has been debated, but the new study claims to have found it, Geologists Jonny Wu (left) and Spencer Fuston (right) claim to have discovered the remains of a long-lost tectonic plate beneath northern Canada. When the concept of seafloor spreading came along, scientists recognized that it was the mechanism to explain how continents could move around Earth’s surface. The movements of the ancient plates can be seen in the animation below. The face of the Earth has changed drastically over its life, with plates shifting and sinking. Over 280,000 people receive our email newsletter. A 3D block diagram across North America showing a mantle tomography image reveals the Slab Unfolding method used to flatten the Farallon tectonic plate. How does it feel for a person caught in one? They call it the Yukon Slab, and when the clock is wound back it appears to fit the calculated shape of the old Resurrection plate. Can we predict them? Active: Have erupted in the last 80 years - there are about 540 of them in the world. What are the dangers of volcanic Eruptions. “When ‘raised’ back to the earth’s surface and reconstructed, the boundaries of this ancient Resurrection tectonic plate match well with the ancient volcanic belts in Washington State and Alaska, providing a much sought after link between the ancient Pacific Ocean and the North American geologic record,” says Jonny Wu, co-author of the study. The population of Montserrat after the volcano erupted. To try to find the remains of the Resurrection plate, the team started by studying existing tomography images of the mantle below North America. The Alaska slab sits beneath the Aleutian Islands and is thought to be the remains of the Kula plate, while the Cascadia slab lies under southern California and represents the remains of Farallon. Over time, the intense heat and pressure there will melt it and change its shape. Certain regions are more. “We are also trying to solve a debate and advocate for which side our data supports.”.
