WebGrassfires can start and spread quickly and are extremely dangerous. 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.
