Puget Lowland Paleoseismology
Contact: Alan Nelson (USGS Golden, Colorado)
Knowledge of when, where, and how often large earthquakes occur is crucial for evaluating the seismic hazards. Through field study of the geologic record of prehistoric earthquakes, geologists are developing a database of the times and magnitudes of large prehistoric crustal earthquakes and their effects in the Puget Lowland region. Information on studies of coastal deposits at specific sites is available in the following Atlas. Information on more detailed studies on the first Holocene fault scarp discovered in the Puget Lowland and paleoliquefaction features near the mouth of the Snohomish River follow.
