    • How Often Do Rainstorms Cause Debris Flows in Burned Areas of the Southwestern U.S.?

      Debris flows, sometimes referred to as mudslides, mudflows, lahars, or debris avalanches, are common types of fast-moving landslides. They usually start on steep hillsides as a result of shallow landslides, or from runoff and erosion that liquefy and accelerate to speeds in excess of 35 mi/h. The consistency of debris flows ranges from thin, watery to thick, rocky mud that can carry large items...

    • Potential Landslide Paths and Implications for Tsunami Hazards in Glacier Bay, Alaska – An Initial Investigation

      Glacier Bay and its inlets are a popular destination for cruise ships and passenger boats; about 540,000 people visited Glacier Bay National Park and Preserve (GBNPP) in 2017. A typical tour of the Bay traverses the entire length up to the glacier calving viewpoints in the Johns Hopkins and Tarr Inlets. A 2018 article “Landslides and Giant Waves” by the National Park Service (NPS) states, “The...

    • Landslides Can Cause More Landslides

      Release Date: MAY 15, 2018The deadliest individual landslides in the U.S. recently were in places where there had previously been a landslide. Why do landslides happen in the same place instead of on nearby slopes that appear to be just as likely, if not more likely, to slide?

    • Mountain Permafrost, Climate Change, and Rock Avalanches in Glacier Bay National Park, Alaska

      Release Date: JUNE 18, 2018We usually hear about landslides and avalanches that are caused by large amounts of rainfall, the shaking from earthquakes, or a volcanic eruption, but we may be hearing more about avalanches caused by the (seemingly innocuous) melting of ice in the coming years.
