2024 Pedersen Lagoon Landslide-Generated Tsunami

A landslide produced a tsunami in Pedersen Lagoon, southwest of Seward, Alaska on Wednesday, August 7th, 2024, at approximately 04:55 AKDT / 12:55 UTC. Preliminary surveying indicates that the landslide generated a tsunami of 17 meters high (approx. 56 ft) or more in Upper Pedersen Lagoon, reducing to about one meter high (approx. 3 feet) in Lower Pedersen Lagoon. Runup heights reported here are...

Puerto Rico Natural Hazards: Landslides | Peligros naturales de Puerto Rico: Deslizamientos de tierra

The Landslide Hazards Program from USGS works to help reduce the impact of landslides to people and infrastructure by furthering our understanding of causes of ground failure and by recommending strategies for risk mitigation. In Puerto Rico, USGS researchers have rigorously studied rainfall-induced landslides to provide maps that depict landslide susceptibility. Educational materials that...

Puerto Rico Landslide Hazard Mitigation Project

The University of Puerto Rico-Mayagüez and USGS produced a landslide hazard map for the main island of Puerto Rico following Hurricane Maria. This map is today used by planners for land use decisions and emergency managers for hazard mitigation plans. To reduce loss from future landslides, the USGS and the University of Puerto Rico-Mayagüez instrumented 15 slopes across the main island and share...
