Lecture Title
Seismic Hazard Across Alaska
Description

With over 49,000 earthquakes recorded in 2020 alone, Alaska is the most seismically active state in the US.  However, the earthquake hazard maps for Alaska have not been updated since 2007.  Background related to the process of a seismic hazard analysis and highlight some of the areas of growth since 2007 will be provided. The presentation will utilize a project that required an analysis of seismic hazards from the north end of the state, extending over 800 miles to the southcentral portion of the state, covering several mountain ranges and different tectonic regions.  Comparisons to the current seismic hazard model used in building codes will be provided and a case will be made for the need to regularly update seismic hazard maps to reduce our risk related to seismic hazards.  We will even touch on some interesting side aspects of earthquakes is permafrost regions, climate change,  and some of the unique aspects of engineering in Alaska.
