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.

10-Year Anniversary of US’s Most Widely Felt Earthquake

Ten years ago, in the early afternoon of August 23, 2011, millions of people throughout the eastern U.S. felt shaking from a magnitude 5.8 earthquake near Mineral, Virginia. No lives were lost, something experts called “lucky” given the extent of shaking, but property damage was estimated to be in the range of $200 to $300 million.

Down to Earth: Complexities of Geology Affect Nuclear Electromagnetic Pulse Hazard 

Geoelectric hazards generated by a nuclear explosion at the outer edge of Earth’s atmosphere can be strongly affected by the electrical conductivity of rock structures beneath the Earth's surface, according to a study led by the U.S. Geological Survey.

Diffuse deformation and surface faulting distribution from sub-metric image correlation along the 2019 Ridgecrest ruptures (California, USA)

The 2019 Mw">Mw 6.4 and 7.1 Ridgecrest, California, earthquake sequence (July 2019) ruptured consecutively a system of high‐angle strike‐slip cross faults (northeast‐ and northwest‐trending) within 34 hr. The complex rupture mechanism was illuminated by seismological and geodetic data, bringing forward the issue of the...

An efficient Bayesian framework for updating PAGER loss estimates

We introduce a Bayesian framework for incorporating time-varying noisy reported data on damage and loss information to update near real-time loss estimates/alerts for the U.S. Geological Survey’s Prompt Assessment of Global Earthquakes for Response (PAGER) system. Initial loss estimation by PAGER immediately following an earthquake includes...

Geologic controls of slow-moving landslides near the U.S. West Coast

Slow-moving landslides, often with nearly imperceptible creeping motion, are an important landscape shaper and a dangerous natural hazard across the globe, yet their spatial distribution and geologic controls are still poorly known owing to a paucity of detailed, large-area observations. Here, we use interferometry of L-band satellite radar images...
