MESSAGE: For COVID-19 Response
A tsunami is a series of waves that can be dangerous and destructive. They can be caused by underwater disturbances or earthquakes. When you hear a tsunami warning, move at once to higher ground and stay there until local authorities say it is safe to return home.
If you have questions about mitigation, e-mail Alaska's Hazard Mitigation Officer, Brent Nichols.
DISTANT SOURCE TSUNAMI HAZARD means the tsunami is generated so far away that the earthquake was not felt at all or only slightly. An estimate can be made of potential danger. Maximum runup heights would only be reached at the shoreline and the maximum distance inland only reached where the coast is low, flat, and unobstructed. "High" means possible runup to 50 foot elevation and reaching up to 1 mile inland. "Moderate" means possible runup to 35 foot elevation and inland up to 3/4 mile. "Low" means possible runup to 20 foot elevation and reaching up to 1/2 mile inland.
All listed communities may have a LOCAL TSUNAMI HAZARD which means a tsunami could be generated in nearby waters and reach your community before a formal warning could be transmitted. These waves may arrive in less than one hour and have historically been the highest, up to 100 foot or more. The estimated possible height in each community is difficult to determine. Coastal residents who feel a very strong earthquake (lasting over 30 seconds or if you have difficulty standing) should move to higher ground immediately.
Historic tsunami information and ongoing numeric studies indicate that tsunami flood threat along the western Alaska coast (Bering Sea) is very low, though there is a higher threat in some instances along the Pribilof Island coasts. We have run a preliminary tsunami propagation model. Two hypothetical tsunami sources (earthquakes of Mw 9.0) were placed in the eastern and western parts of the Aleutian chain. The tsunami waves propagated through the Northern Pacific and into the Bering Sea. The continental shelf in the Bering Sea substantially dissipates tsunami energy and slows down the waves. As a result, tsunami waves arrive at Hawaii before they reach the Bering Sea coastline, which gives sufficient warning time to those communities. Higher amplitudes were calculated for St. George and St. Paul islands due to their proximity to the continental slope. The Bristol Bay area has only an estimated >1 meter wave height potential.
Division of Homeland Security & Emergency Management
Mr. Michael "Mike" Sutton was appointed as acting director of the Alaska Division of Homeland Security and Emergency Management (DHS&EM) within the Alaska Department of Military and Veterans Affairs on December 11, 2017. He was appointed Deputy Director on June 5, 2015.
Mr. Sutton started his career with the State of Alaska in November of 2005. Mike was the Exercise Program manager in the DHS&EM Preparedness Branch where he planned, coordinated, executed and evaluated the largest homeland security exercise in Alaska's history - Alaska Shield 07.
Following a highly successful exercise and after more than 28 years of public service, Mr. Sutton ventured into the private sector and started his own business. As president of Alaska's leading veteran-owned emergency management consulting firm, he won contracts for developing an Emergency Operations Plan for the National Science Foundation's Antarctic outpost at McMurdo Station, writing the Alaska Catastrophic Response Plan for FEMA Region X, creating the first Regional Tribal Response Plan for FEMA, and updating emergency operations plans for dozens of Alaska's borough's and communities.
Mr. Sutton retired from the U.S. Air Force in 2005 after 25 years of service with over 2,400 hours in the F-4E and RC-135 aircraft.
Mr. Sutton holds a Bachelors of Business Administration Degree from Texas A&M University graduating in 1978, and completed post-graduate work in Leadership, Management, and Cultural Diversity. Mr. Sutton is a Distinguished Graduate of Squadron Officer's School, completed Air Command and Staff College, and is a graduate of Armed Forces Staff College.
Mike is an avid outdoorsman and can be found on most weekends with his wife Alisha on one of Alaska's many hiking trails or on their boat out in Prince William Sound. They have 3 grown children and live in Anchorage, Alaska.
