Dead man zone : ウィキペディア英語版 | Dead man zone
The dead man zone is defined as the area directly around a bushfire that is likely to burn within five minutes given the current wind conditions or an anticipated change in wind direction. The distance this zone extends from the firefront is highly dependent on terrain, windspeed, fuel type and composition, relative humidity and ambient temperature, and can range from under 100 m to well over 1 km. ==Project Vesta== The term ''dead man zone'' was coined by members of the CSIRO research team in Australia who were investigating the spread of bushfires (Project Vesta). Project Vesta, headed by scientist Phil Cheney, found that when the wind changes direction, the line of fire will move out at its maximum rate of spread almost immediately, and that that speed was nearly three times what was previously thought. Project Vesta's research into bushfire behaviour makes up the majority of what is known about bushfires today.
