The Hazards Caucus Alliance, a network that supports the Congressional Hazards Caucus, hosted a briefing on April 6 about how geologic and hazards mapping and monitoring are used to prepare and protect communities from natural hazards.
A tsunami is generated when a large volume of water is rapidly displaced, usually as a result of a submarine or coastal earthquake—though marine landslides, volcanic eruptions, nuclear weapons testing, and asteroid impacts can all potentially create tsunamis. All coastal states have a tsunami risk, but the most powerful tsunamis are created in the Pacific leaving those coastal states, including Hawaii, most at risk.
The Tsunami Evacuation Map from the Washington Division of Geology and Earth Resources provides a large amount of information about tsunami evacuation procedures for the state of Washington. Each of the shaded areas in the image above can be zoomed in on for more detailed information including:
The American Society of Civil Engineers (ASCE), which houses the Geo-Institute, announced that the 2016 revision of its ASCE Minimum Design Loads and Associated Criteria for Buildings and Other Structures will, for the first time, contain a chapter on tsunamis. Part of the creation of this chapter was the establishment of a committee to study the response of buildings, and their internal structures, to tsunamis. The committee was officially established in February of 2011, just weeks before the devastating Tohoko Earthquake and Tsunami in Japan. Click for more:
