My master thesis is directed at solving the earthquake slip record deficit along the Teton fault in Grand Teton National Park, Wyoming, USA. I mainly do this by looking at geophysical data, similar to “snapshots” of the lake bathymetry in Jackson Lake, which is directly east of the Teton range. Within these lake sediment maps I identify seismites--underwater landslides that are likely caused by large ground-shaking events along the Teton fault. I also use macro-organic samples from collected lake cores to do radiocarbon dating and assign a numerical value to these seismites. Adding to the earthquake record is essential for the Wyoming community and surround regions, as we currently do not have a record of any earthquakes in the last five thousand years, making the Teton fault extremely overdo for a large earthquake. With its proximity to Yellowstone national park, it is pertinent that we are able to distinguish the earthquake record to evaluate the hazard in this area.
