The TIM index map shows the extents of released maps in this series. Downloadable tsunami zone maps. A tsunami that originated along the Washington, Oregon, and California coasts in 1700 overran Native American fishing camps and caused damage in Japan. If a tsunami-causing disturbance occurs close to the coastline, a resulting tsunami can reach coastal communities within minutes. The height above mean sea level of the two oppositely traveling tsunamis is approximately half that of the original tsunami (Panel 1). Some limitations to this map needs proper consideration and as follows: The extent of tsunami inundation is based on current physical conditions of the study area. All of these triggers can occur in the United States. Risk map Risk maps show the consequences of an event with a likelihood scale. This new study and modeling is based upon a simulated 2500 year event, … Directed by this new law, the Department of Geology and Mineral Industries (DOGAMI) prepared a series of tsunami hazard maps at a scale of one inch to 2,000 feet of the entire Oregon coast (available as Open-File Reports O-95-09 through O-95-66 and explained in O-95-67, which also contains an index map of the individual tsunami warning maps). This map shows seven earthquake-generated tsunami events in the United States from the years 900 to 1964. All additional questions or issues with the map tool can be sent to uaf_aec@alaska.edu. … The occurrence and potential for tsunamis on the coasts of the United States is not out of the question. California tsunami inundation maps . Communities are selected with consideration to their tsunami hazard exposure, location, infrastructure, availability of data, and willingness to incorporate the results in a comprehensive mitigation plan. Zone 10, North. Please contact your local emergency officials to find out where evacuation routes and tsunami shelters are in your community. Click on the index map to see a tabloid-size PDF | 34.5- x 45.25-inch PDF.. Develop your family emergency plan. The speed at which both tsunamis travel varies as the square root of the water depth. In the wake of the Indian Ocean disaster, the United States is redoubling its efforts to assess the Nation's tsunami hazards, provide tsunami education, and improve its system for tsunami warning. It is not verified against known seismic history of Alaska (i.e., paleoseismology), nor does it include the probabilistic effects of tsunamis caused by submarine landslides. No. Tsunami hazard maps of the Kodiak area, Alaska 1 TSUNAMI HAZARD MAPS OF THE KODIAK AREA, ALASKA by E.N. For more information on how to use the tsunami map tool please see this instructional video. Because of the complicated behavior of tsunami waves near the coast, the first runup of a tsunami is often not the largest, emphasizing the importance of not returning to a beach many hours after a tsunami first hits. About Tsunami Hazard Maps Select a community from the menu on the right. Earthquakes are commonly associated with ground shaking that is a result of elastic waves traveling through the solid earth.
