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.

An improved empirical model for predicting postfire debris-flow volume in the western United States An improved empirical model for predicting postfire debris-flow volume in the western United States
Reliable estimates of debris-flow volume can be used to help predict the magnitude of debris-flow hazards following wildfire in the western United States. In this study, we compiled and used a database of 227 postfire debris-flow volumes that were collected across the western United States to develop a multiple linear regression model for predicting postfire debris-flow volume. We...
A 481 m-high landslide-tsunami in a cruise ship-frequented Alaska fjord A 481 m-high landslide-tsunami in a cruise ship-frequented Alaska fjord
Early in the morning of 10 August 2025, a >64 × 106–cubic meter landslide struck Tracy Arm fjord in Alaska. The landslide was preconditioned by glacial retreat caused by climate change. The resulting 481-meter runup megatsunami followed an initial 100-meter-high breaking wave traveling at >70 meters per second. The landslide was preceded by several days of microseismicity, which...
The United States Magnetotelluric Array and the National Impedance Map The United States Magnetotelluric Array and the National Impedance Map
The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long-period magnetotelluric stations covering the entirety of the contiguous United States on a quasi-regular 70 km grid. Funding across multiple federal agencies was critical to sustaining this effort to its completion. Important components of the project included...
