Adak is 1100 miles SW of Anchorage in the Aleutian chain! • Tsunami and earthquake presentations given at two ATEP teacher seminars • Sand Point awaiting final Tsunami. Ready recognition • Governor proclamation for “Alaska Tsunami Awareness Week” • Live Code Test conducted during tsunami awareness week • Numerous PSA’s broadcast on media prior to Live Code Test • Coordination with Cooperative Program for Operational Meteorology, Education and Training (COMET) to develop an Emergency Manager Tsunami Education Module (direct NOAA funding) • Evacuation signs purchased for Whittier, 3 replacement signs to Sitka • Siren survey sent to coastal communities

Alaska Division of Homeland Security & Emergency Management FY-09 Grant $633, 533 2009 Accomplishments continued • Reproduced 1, 000 copies of Ocean Fury • Purchased Weather Radios • Distributed numerous educational materials (children’s Tsunami and Earthquake booklets, Are You ready for the Next Big Quake • Warning sirens installed in five communities (previous funding) • Tsunami Warning System training at TWC for WCM’s • Seven warning sirens installed in Valdez (HS funding) • Editing a new children’s tsunami booklet 2009 Issues • Procurement problems for warning sirens continues but is being alleviated • Staffing issues • No cost extension request most likely

Whittier: recent activities § AEIC, ADG&GS and the ADHS&EM conducted an introductory visit to Whittier and introduced the tsunami inundation mapping project. § During the recent GPS field survey in Whittier, we collected more than 100 elevation measurements in order to improve the coastal area of Whittier DEM. § We analyzed and modeled the underwater slope failures in Passage Canal that generated destructive tsunami waves in Whittier. § We modeled seiches observed in the Passage Canal in 1964 that were caused by tilting of the bed of the fjord during the earthquake. § We conducted numerical modeling of the tectonic tsunami scenarios and prepared the first draft of the report.

Seward: community visit, 12/2/2009 § AEIC and ADG&GS presented results of tsunami inundation mapping of the upper Resurrection Bay to the City of Seward and to the public. The presentation was very well received by the community. § The City of Seward and the Kenai Peninsula Borough are now conducting user review; the report and the maps are in publication.
