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.

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.

2014 South Napa Earthquake in California
May 15, 2017

Early on the morning of August 24, 2014, Loren Turner was awoken by clattering window blinds, a moving bed, and the sound of water splashing out of his backyard pool. He experienced what is now named the “South Napa Earthquake.”

A prototype operational earthquake loss model for California based on UCERF3-ETAS – A first look at valuation

We present a prototype operational loss model based on UCERF3-ETAS, which is the third Uniform California Earthquake Rupture Forecast with an Epidemic Type Aftershock Sequence (ETAS) component. As such, UCERF3-ETAS represents the first earthquake forecast to relax fault segmentation assumptions and to include multi-fault ruptures, elastic-rebound...

Estimating rupture distances without a rupture

Most ground motion prediction equations (GMPEs) require distances that are defined relative to a rupture model, such as the distance to the surface projection of the rupture (RJB) or the closest distance to the rupture plane (RRUP). There are a number of situations in which GMPEs are used where it is either necessary or advantageous to derive...

Geoelectric monitoring at the Boulder magnetic observatory

Despite its importance to a range of applied and fundamental studies, and obvious parallels to a robust network of magnetic-field observatories, long-term geoelectric field monitoring is rarely performed. The installation of a new geoelectric monitoring system at the Boulder magnetic observatory of the US Geological Survey is summarized. Data from...
