This report is one in a series of digital maps, data files, and reports generated by the US Geological Survey (USGS) to provide geologic information for the Interior Columbia Basin Ecosystem Management Project (ICBEMP), a US Forest Service and Bureau of Land Management interagency project. The various digital maps and data files that were provided by teh USGS and that are available in this and other reports are being used in a geographic information system (GIS)-based ecosystem assessment. The assessment will include a comprehensive analysis of past, present, and future ecosystem conditions within the general area of the Columbia River Basin east of the Cascade Mountains.
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....
