“Post-Fire Debris-Flow Early Warning” is USGS public lecture on Oct. 25

Dennis M. Staley and Jason W. Kean, USGS Landslide Hazards Program, and Mark Jackson, National Weather Service – Los Angeles will talk about:

• Post-re debris flows can initiate after only a few minutes of intense rain, and during the first storm following wildfire.
• Early warning systems must provide sufficient time to make informed decisions and take reasonable preventative action.
• If you’re relying upon real-time measurements of stream ow or rainfall in your watershed to decide when to take action, it is too late
• Measurements of debris flows are important for improving our understanding of these phenomena, but are of limited utility for early warning.

The free public lecture will talk place at 7:00 pm on Oct. 25 at the Rambo Auditorium/Bldg. 3, 345 Middlefield Rd., Menlo Park.
