Grassfires can travel up to 25 km per hour and pulse even faster over short distances. Grass is a fine fuel and burns faster than bush or forests. Grassfires tend to be less intense and produce fewer embers than bushfires, but still generate enormous amounts of radiant heat. rosewood eating disorder clinic arizona
