Catastrophic Icefall Hazard Assessment, Avoidance Procedures & Mitigations Strategies-Phase I Literature Review

The incidence of icefall is one of the most underrepresented and underappreciated of all the natural hazards. Falling pieces of ice are subject to melting and sublimation, and evidence of such events may be gone in a matter of days or even hours. There is very little existing research and engineering design criteria relative to icefall hazard mitigation. Alaska Department of Transportation and Public Facilities (AKDOT&PF) is undertaking research aimed at better understanding icefall hazards and eventually quantifying risk of impact along state highways, in an effort to mitigate icefall hazards. The research project was broken down into two (initial) distinct phases. This research report summarizes the results of the Phase No. 1 Literature Review, which includes potential sources of data that could be included for further site-specific studies. Sources of data include personal communications, documented icefall events, media accounts, technical literature, Alaska-specific documents, Alaska-specific web based sources, and potential software (for technical evaluations). Data sources are ranked according to perceived value for use during Phase No. 2 studies. Data ranked as “high” and “moderate” value will likely be further referenced during Phase No. 2 site-specific studies at seven key sites throughout the State of Alaska.
