Geologic Hazards Science Center
The Geologic Hazards Science Center (GHSC), on the Colorado School of Mines campus, is home to the National Earthquake Information Center (NEIC), many scientists in the Earthquake Hazards Program and Landslide Hazards Program, as well as the Geomagnetism Program staff.
Earthquake Hazards Program
Earthquake Hazards Program
The Earthquake Hazards Program provides research and information products for earthquake loss reduction, including hazard and risk assessments, comprehensive real-time earthquake monitoring, and public outreach.
Landslide Hazards Program
Landslide Hazards Program
The National Landslide Hazards Program strives to reduce long-term losses from landslide hazards by improving our understanding of the causes of ground failure and suggesting mitigation strategies.
Geomagnetism Program
Geomagnetism Program
The Geomagnetism Program provides continuous records of magnetic field variations; disseminates magnetic data; and conducts research into the nature of geomagnetic variations for purposes of scientific understanding and hazard mitigation.

Characterizing changes in postfire debris-flow hazard as burned areas recover Characterizing changes in postfire debris-flow hazard as burned areas recover
Emergency assessments of postfire debris-flow hazards that are performed by the U.S. Geological Survey (USGS) provide estimates of debris-flow likelihood and rainfall triggering conditions that are used for evaluating and managing runoff-generated debris-flow hazards in recently burned areas throughout the western United States. Although the immediate postfire period, within roughly one...
Albuquerque Seismological Laboratory strategic vision Albuquerque Seismological Laboratory strategic vision
This circular presents a strategic outlook for the U.S. Geological Survey (USGS) Albuquerque Seismological Laboratory (ASL) for the next 10 years (2026–36). The ASL is a USGS field office in the Geological Hazards Science Center that operates portions of the Advanced National Seismic System and the Global Seismographic Network and focuses on fundamental research for instrumentation...
Rapid seismic and infrasound assessment of large landslides: A case study from Denali National Park and Preserve (Alaska) Rapid seismic and infrasound assessment of large landslides: A case study from Denali National Park and Preserve (Alaska)
Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide-generated seismic and infrasound (low-frequency atmospheric sound) waves can be remotely detected in near real-time. This information can significantly...
