Landslides

Earthquake-triggered ground-failure, such as landsliding and liquefaction, can contribute significantly to losses, but our current ability to accurately include them in earthquake hazard analyses is limited.

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 in the San Francisco Bay area (SFBA) of California impact people, infrastructure, and the environment, and are commonly induced by intense or prolonged rainfall associated with strong winter storms.

Release Date: OCTOBER 15, 2018 USGS scientists have been pursuing a way to assess debris-flow hazards before a fire occurs.

Release Date: JUNE 25, 2018 USGS scientists have been developing a system to quickly identify areas where landslides may have been triggered by a significant earthquake.

Release Date: JUNE 18, 2018 We 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.

Landslide Susceptibility Data and Maps provide tools for hazard assessment prior to an event that may cause landslides.

Release Date: JUNE 11, 2018 Sluggishly-moving earthflows can help us learn what controls the starting and stopping of landslides.

Monitoring at this site is for researching rainfall thresholds for forecasting landslide potential. Shallow landslides are common on coastal bluffs overlooking Puget Sound.

Landslides in the West Hills of Portland pose a hazard to people and property.

The USGS and its cooperators have installed instruments in a steep, recently clear-cut basin in the Elliott State Forest.

The USGS and its cooperators have installed instruments in a steep hillside about 20 km southeast of Reedsport in the Elliott State Forest.
