Geologic Hazards Science Center
Home
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
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.
Earthquake HazardsLandslide 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.
Landslide HazardsGeomagnetism 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.

Modeling hydrologic processes associated with soil saturation and debris flow initiation during the September 2013 storm, Colorado Front Range
Seven days of extreme rainfall during September 2013 produced more than 1100 debris flows in the Colorado Front Range, about 78% of which occurred on south-facing slopes (SFS). Previously published soil moisture (volumetric water content) observations suggest that SFS were wetter than north-facing slopes (NFS) during the event, which contrasts...
Timilsina, Sujana; Niemann, Jeffrey D.; Rathburn, Sara L.; Rengers, Francis K.; Nelson, Peter A. Evaluation of simulated ground motions using probabilistic seismic demand analysis: CyberShake (ver. 15.12) simulations for Ordinary Standard Bridges
There is a need for benchmarking and validating simulated ground motions in order for them to be utilized by the engineering community. Such validation may be geared towards a specific ground motion simulation method, a target engineering application, and a specific location; the validation presented herein focuses on a bridge engineering...
Fayaz, Jawad; Rezaeian, Sanaz; Zareian, Farzin Rapid sensitivity analysis for reducing uncertainty in landslide hazard assessments
One of the challenges in assessing temporal and spatial aspects of landslide hazard using process-based models is estimating model input parameters, especially in areas where limited measurements of soil and rock properties are available. In an effort to simplify and streamline parameter estimation, development of a simple, rapid approach to...
