| Notes | Major earthquakes can generate tsunamis. Tsunamis can erode coastal soils and deposit marine sediment far inland. In this Bachelors thesis, the author asks if it is possible to determine the size and strength of an earthquake that took place far in the past based on the depositional record of sand sheets in estuaries. The shape of the tsunami wave, the shape of the estuary and the bed roughness of the estuary (grain size, plants, structures on the bed) all contribute to the size of the sand sheet that is deposited. Here, the author uses a mathematical model to explore what happened in the Alsea estuary after the 1700 C.E. earthquake. Major professor was Andrew Meigs. |
