Rare Event Risk Assessment Process (RERAP)
The Rare Event Risk Assessment Process (RERAP) helps calculate the information needed to manage prescribed fires, wildland fire use fires, and wildland fires. RERAP allows a user to dynamically calculate the risk of undesired fire movement, including how to: 1) identify high and low risk opportunities for wildland fire use and general prescription control strategies; and 2) estimate fire movement and spread events based on historical weather information and professional knowledge. The RERAP program consists of three modules: 1) the Term Module, which allows a user to calculate the Weibull waiting-time probability distribution for fire-stopping events; 2) the Spread Module, which allows a user to estimate the rate of fire spread toward a designated location; and 3) the Risk Module, which combines information from term event information and fire spread events and allows a user to specify and combine fire-stopping and fire movement waiting-time probability distributions to estimate the likelihood of a fire impacting a designated location before a fire-stopping weather event.

FIREHouse is a collaboration between the Fire and Environmental Research Applications Team (FERA) of the USDA Forest Service Pacific Northwest Research Station, Pacific Wildland Fire Sciences Laboratory; the University of Washington; the National Park Service; the Bureau of Land Management – Alaska Fire Service; the US Fish and Wildlife Service; and the National Biological Information Infrastructure (NBII). The NBII is a broad, collaborative program that provides increased access to data and information on the nation’s biological resources. Funding for FIREHouse has been provided by the Joint Fire Science Program (JFSP) and NBII. FIREHouse is coordinating efforts with the Fire Research and Management Exchange System (FRAMES) project team. Content on FIREHouse will provide substantial contributions to the Northwest Fire Science Portal and the Alaska Fire Science Portal.
