The public can find out how to prepare for and protect themselves from flash floods and debris flows, commonly known as mudflows; see satellite imagery of the burned areas; learn about real-time stream-flow/flood information; listen to interviews with scientists; and view a video and photo gallery.
The USGS Multi-Hazards Demonstration Project team is coordinating a post-Southern California wildfire response around four public safety goals - assess and identify debris-flow danger, size and potential flows; estimate flood risk; assess biodiversity and ecological impacts; and assess surface water quality impact on human health.
