(a) Short-term fire behavior results for the Mississippi Impact Area fire in Alaska (AK-MID-000138) from May 2010. The simulation was for three 10-hour burn periods under constant wind and weather conditions. Shaded areas display fire arrival times in 5-hour intervals. Red vectors represent the major fire spread pathways based on the minimum travel time (MTT) algorithm [14]. (b) Critical infrastructure intersected with FSPro probabilities [16] for the Schultz fire in Arizona (AZ-COF-000181) from June 2010 illustrates the graphical output associated with a rapid assessment of values at risk (RAVAR). This map displays the probability of fire spread impacting critical infrastructure, such as structures, gas pipelines, and power transmission lines over a 14-day period based on simulating 2000 fires.
