Native American Legends of Tsunamis in the Pacific Northwest

For general interest, studies and accounts regarding Native American Legends of possible tsunamis in the Pacific Northwest are excerpted below. Much of the information on this page was presented by Jim Bergeron, Oregon Sea Grant, Astoria Extension at a 1995 Meeting in Seaside, Oregon. Those interested in the subject are encouraged to refer to the original reports:

San Francisco Bay Basic Tide Model

This web page provides files that may be used to run a basic depth-averaged (2DH) Deltares Delft3D version 4.00.01 astronomic tide model for San Francisco Bay. It was developed with the primary aim of assessing water level fluctuations and flow conditions in the vicinity of the Golden Gate (Elias and Hansen 2013).

Using Video Imagery to Study Coastal Change: Barter Island, Alaska

For a short study period, two video cameras overlooked the coast from atop the coastal bluff of Barter Island in northern Alaska. The purpose was to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

Sea Level and Storm Hazards: Past and Present

Sea level and Storm Hazards: Past and Present is a multidisciplinary study of past changes in sea level. Prehistoric shorelines can be used as a baseline for current and future sea level changes under warmer-than-present climate. Emphasis is placed on looking at sea levels during warm periods of the last 500,000 years as well as how base level changes increase the risk of coastal inundation...

Reconstructing Ocean Circulation & Hydroclimate in the Subtropical Atlantic

Changes in rainfall patterns as a result of anthropogenic climate change are already having large ecological and socioeconomic impacts across the globe. Increases in flood damage, wildfire damage, and agricultural losses can all be attributed to anomalous rainfall events and prolonged droughts across the United States in recent years. Additionally, Atlantic Ocean circulation, which has a large...

Preliminary Analysis of the April 2007 Solomon Islands Tsunami, Southwest Pacific Ocean

The tsunami that was triggered by a magnitude 8.1 earthquake on April 1, 2007, in the Solomon Islands caused significant damage and loss of life. In the hopes that disasters such as this can be avoided in the future, we attempt to understand the mechanism and impact of this tsunami. The information presented here is focused on geologic aspects of the disaster.

Estuarine Processes, Hazards, and Ecosystems-Study Sites

Estuaries are dynamic environments where complex interactions between the atmosphere, ocean, watershed, ecosystems, and human infrastructure take place. They serve as valuable ecological habitat and provide numerous ecosystem services and recreational opportunities. However, they are modified by physical processes such as storms and sea-level rise, while anthropogenic impacts such as nutrient...
