Even after wildland fires are extinguished, the dangers may not be over. A combination of recently burned surficial soil and rainfall may cause deadly damage. In this video we explore some of the implications of raindrop splash in the formation of sudden mudflows. To better understand the behavior of raindrops on post-wildfire soil, a series of experiments was recorded with a high-speed camera.
