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

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 Hazards

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.

Landslide Hazards

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.

Detailed information about landslide occurrence is the foundation for advancing process understanding, susceptibility mapping, and risk reduction. Despite the recent revolution in digital elevation data and remote sensing technologies, landslide mapping remains resource intensive. Consequently, a modern, comprehensive map of landslide occurrence...

Scientific knowledge and engineering tools for predicting coastal erosion are largely confined to temperate climate zones that are dominated by non-cohesive sediments. The pattern of erosion exhibited by the ice-bonded permafrost bluffs in Arctic Alaska, however, is not well explained by these tools. Investigation of the oceanographic, thermal,...
