Stratigraphic and microfossil evidence for late Holocene tsunamis at Swantown marsh, Whidbey Island, Washington

Authors(s) and Affiliation(s)



The AA. report stratigraphic and paleoecologic findings from a tidal marsh on the west coast of Whidbey Island, Washington, where 4 muddy sand layers were found in the peat underlying the marsh. These sand sheets record repeated inundation of the marsh over a short time period by distinct pulses of sediment-laden ocean water, consistent with deposition by a tsunami wave train. The layers have been radiocarbon-dated. The 2 older layers do not correlate with plate-boundary events. They may be products of tsunamis caused by earthquakes on local faults in the Strait of Juan de Fuca or by submarine landslides in this area
