Article
Extreme wildfire events are fires that move too fast or erratically for adequate evacuation or notification. Modeling evacuations from these wildfires is markedly different than modeling disasters with slower or more predictable movements. There is a gap in our knowledge of human evacuation behavior under these conditions. In this paper, we develop...
