Summary
Abstract: Abstract

The Cascadia Tsunami Deposit Database contains data on the location and
sedimentological properties of tsunami deposits found along the Cascadia
margin. Data have been compiled from 52 studies, documenting 59 sites from
northern California to Vancouver Island, British Columbia that contain known or
potential tsunami deposits. Bibliographical references are provided for all
sites included in the database. Cascadia tsunami deposits are usually seen as
anomalous sand layers in coastal marsh or lake sediments. The studies cited in
the database use numerous criteria based on sedimentary characteristics to
distinguish tsunami deposits from sand layers deposited by other processes,
such as river flooding and storm surges. Several studies cited in the database
contain evidence for more than one tsunami at a site. Data categories include
age, thickness, layering, grainsize, and other sedimentological characteristics
of Cascadia tsunami deposits. The database documents the variability observed
in tsunami deposits found along the Cascadia margin.
