Landslide Hazards
Home
The primary objective of the National Landslide Hazards Program is to reduce long-term losses from landslide hazards by improving our understanding of the causes of ground failure and suggesting mitigation strategies.

As Aftershocks Continue in Puerto Rico, USGS Supports Quake Recovery
A sequence of earthquakes in southwest Puerto Rico continues to affect people living there, with the largest recent aftershock a magnitude 5.2 on Jan. 15. U.S. Geological Survey scientists on the island and the mainland are providing up-to-date scientific information to help the Commonwealth government and the Federal Emergency Management Agency make decisions that protect the public.
Deep Landslides Not Reactivated by 2018 Anchorage Quake (SSA News)
"Major landslides triggered by the 1964 magnitude 9.2 Great Alaska earthquake responded to, but were not reactivated by, the magnitude 7.1 Anchorage earthquake that took place 30 November 2018, researchers concluded in a new study published in Seismological Research Letters."

Landslide Risks Highlighted in New Online Tool
The U.S. Geological Survey today unveiled a new web-based interactive map that marks an important step toward mapping areas that could be at higher risk for future landslides. In collaboration with state geological surveys and other federal agencies, USGS has compiled much of the existing landslide data into a searchable, web-based interactive map called the U.S. Landslide Inventory Map.

Physically based estimation of rainfall thresholds triggering shallow landslides in volcanic slopes of southern Italy
On the 4th and 5th of March 2005, about 100 rainfall-induced landslides occurred along volcanic slopes of Camaldoli Hill in Naples, Italy. These started as soil slips in the upper substratum of incoherent and welded volcaniclastic deposits, then evolved downslope according to debris avalanche and debris flow mechanisms. This specific case of slope...
Fusco, F.; De Vita, P.; Mirus, Benjamin B.; Baum, Rex L.; Allocca, V.; Tufano, R.; Calcaterra, D. An initial assessment of areas where landslides could enter the West Arm of Glacier Bay, Alaska and implications for tsunami hazards
Tsunamis generated by landslides in Glacier Bay are uncommon, but have potential to be extraordinarily destructive when they occur. This article identifies areas that are susceptible to landslides that could generate tsunamis and discusses approaches to characterize hazard and risk from these events.
Coe, Jeffrey A.; Schmitt, Robert G.; Bessette-Kirton, Erin Effects of infiltration characteristics on the spatial-temporal evolution of stability of an interstate highway embankment
Infiltration-induced landslides are among the most common natural disasters threatening modern civilization, but conventional methods for studying the triggering mechanisms and predicting the occurrence of these slides are limited by incomplete consideration of underlying physical processes and the lack of precision inherent in limit-equilibrium...
