In April 2014, the Washington Division of Geology and Earth Resources (DGER) received the 2014 Western States Seismic Policy Council Award in Excellence for Response Plans/Materials. Stephen Slaughter, a hazards geologist and member of the Washington Coastal Hazards Resilience Network (CHRN) was a primary author to the award-winning document: Report of Investigations 36. Earthquake-induced landslide and liquefaction susceptibility and initiation potential maps for tsunami inundation zones in Aberdeen, Hoquiam, and Cosmopolis, Grays Harbor County, Washington for a M9+ Cascadia subduction zone event. The report assesses the earthquake-induced ground failure potential, including soil liquefaction and landslides on specific areas within Grays Harbor County.
"The objective of the report is to assist city and emergency management officials in evaluating the suitability of existing evacuation routes and assembly areas for potential susceptibility to ground failure from a M9+ Cascadia subduction zone earthquake. It also provides officials, the results of the report call for the need of alternative escape routes"
"As a result of the report, some evacuation routes have already been modified, and there may be additional additions, removals, or other modifications to current evacuation routes and assembly areas"
