Tsunami Hazard Assessment for Homer

The Alaska Tsunami modeling group at the Geophysical Institute, UAF, in cooperation with ADG&GS is finishing a tsunami hazard assessment for the community of Homer. In this project we modeled an extent of inundation for tsunamis generated by earthquakes and local submarine landslide sources. We consider earthquakes as large as the 2011 Tohoku earthquake in Japan. We also consider local underwater landslide events in Kachemak Bay as possible tsunami scenarios. The results show that the maximum predicted wave height resulting from a tectonic tsunami is 10-12 meters (33 ft - 40 ft) in Homer, while the maximum landslide-generated tsunami may cause run-up of up to 4 meters (13 ft.) on the Homer Spit. Numerical modeling results, combined with historical observations in the region, are intended to provide guidance to local emergency management in tsunami hazard assessment, evacuation planning, and public education for the reduction of future tsunami risk.
