Tsunami and Seiche Risk Framework for the Great Salt Lake
Recent geologic studies and high quality data provide improved characterization of the tectonic setting under the Great Salt Lake, dominated by the East Great Salt Lake fault. Complex geology, seismicity, broad shallow bathymetry, and a large range of historic water level fluctuations in the lake pose significant seismic and wind induced flooding hazards, including tsunami and seiche. These hazards differ significantly from typical mountain lake seiching caused by massive plunging failures of high steep slopes. Rather, fault rupture displacements and related area subsidence can produce damaging tsunami waves and seiching across the broad shallow flat lake basin. Strong wind generated waves also pose a hazard. Damaging impacts include shoreline scour, liquefaction and flooding of developed areas. This paper presents a conceptual model of tsunami and seiche generation, propagation and runup, focusing on resulting flooding hazards in the south and east shores of the lake.
