1 Tectonics in the USA LO: Explain the threat posed by plate tectonics in the USA

2 You should have studied plate tectonics before! Is this how you remember plate tectonics working?

5 How do plate tectonics impact the United States of America?

6 Earthquakes in the USA

10 Tsunami hazard Disaster zone? A huge 'megathrust' earthquake could spark a tsunami and devastate the U.S. northwest if the Juan de Fuca plate is forced further under the North America plate on the Cascadia fault line

11 Review Explain the threat posed by plate tectonics in the USA… Success criteria: Describe the plate margins that are found in the USA and explain how these cause tectonic hazards? Name specific locations Why are certain locations more risky than others?
