After a wildfire, the impact on the geography of the burnt area undergoes changes due to not only the clearing of vegetation and structures, but also the change that happen due to the extreme heat. These impacts create conditions where debris flows can be especially intense in the months and years following the fire. In this episode, geologist Dr. Michael Lamb, who created and runs the Caltech Earth Surface Dynamics Laboratory, shares what to expect from potential debris flows based on the models he's created in his lab and what we know about the burn areas in Altadena, Malibu, and the Pacific Palisades.
