Physical Results of Earthquakes They Shape Our Landscape As plates move, we may feel these movements as earthquakes If there were no plate motions, our planet would not look like home There would be no mountains, no valleys, no plateaus More than disasters on the human scale Earth Shaking = Earth Shaping Earthquakes and other tectonic activities have been occurring for as long as the Earth has existed. Events range from small cracks in the soil to the raising and lowering of huge chunks of lithosphere Happens over long periods of time Faults Where rock is strained beyond limit, it will fracture, and the rock mass on either side will move abruptly. Folds Accumulated stress and strain within rocks of the lithosphere may cause great warps or folds in rock layers. Soil Liquefaction Much of the dollar damage due to earthquakes result from liquefaction Table group exploration and discussion Video of liquefaction in Japan; video Tokyo Park Landslides Earthquakes trigger many landslides, particularly in the rainy season Video of landslides – general Video of landslide – Mt. St. Helens (lahar) Graphic showing Japan flooding Due to earthquake and landslide Underwater Earthquakes Tsunamis Video Japan 2011, raw footage Video Indonesia 2004 Deaths due to Earthquakes/Tsunamis Read Read “I survived a tsunami” Complete the worksheet on one side to order the events On the back, answer the questions: “In what ways did Masahiro exhibit courage?” What do you think of Masahiro? How do you think you would have reacted under the same circumstances? Aftershock: A smaller earthquake that follows a more powerful earthquake in same area. Liquefaction: A process by which the shaking of the ground causes loose, wet soil to act like a liquid. Tsunami: A water wave caused by an earthquake, volcanic eruption or landslide.
