Barry Arm, Alaska Landslide and Tsunami Monitoring

A large steep slope in the Barry Arm fjord 30 miles (50 kilometers) northeast of Whittier, Alaska has the potential to fall into the water and generate a tsunami that could have devastating local effects on those who live, work, and recreate in and around Whittier and in northern Prince William Sound.

Overview of Hazards and Risk Assessments

Landslide hazard and risk assessments help people understand the dangers from landslides to their towns and cities, homes, facilities, and businesses. Landslide hazard assessments are estimates of the probability that landslides will affect a particular area or location, typically within a given timeframe.

Preliminary Landslide Assessments

The USGS seeks to provide effective situational awareness about long-term and ongoing hazardous events to improve emergency response, inform the public, and minimize societal disruption. Large, highly mobile landslides generate seismic signals that can be detected by seismic monitoring networks and leave scars and deposits that can be detected from high-resolution remote-sensing imagery. Following...

Early Warning System

Once the smoke clears from a wildfire, the danger is not over!! Other hazards, such as flash floods and debris flows, now become the focus. Areas recently burned by wildfires are particularly susceptible to flash floods and debris flows during rainstorms.

Emergency Assessment of Post-Fire Debris-Flow Hazards

Estimates of the probability and volume of debris flows that may be produced by a storm in a recently burned area, using a model with characteristics related to basin shape, burn severity, soil properties, and rainfall. Wildfire can significantly alter the hydrologic response of a watershed to the extent that even modest rainstorms can produce dangerous flash floods and debris flows. The USGS...
