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.”

Small variations in the density of the earth’s crust—undetectable to humans without sensitive instruments—influence where earthquakes may occur in the central United States. These new findings from the U.S. Geological Survey, published today in Nature Communications, may allow scientists to map where future seismicity in the center of the country is most likely.

K2 Seismic Station

The U. S. Geological Survey is seeking volunteers to host temporary seismic stations in the Walnut Creek/Pleasant Hill/Concord California area. Volunteers will be assisting with a new ground motion study that will begin in March 2017.

Alternative rupture-scaling relationships for subduction interface and other offshore environments

Alternative fault-rupture-scaling relationships are developed for Mw 7.1– 9.5 subduction interface earthquakes using a new database of consistently derived finitefault rupture models from teleseismic inversion. Scaling relationships are derived for rupture area, rupture length, rupture width, maximum slip, and average slip. These relationships...

Limiting the effects of earthquakes on gravitational-wave interferometers

Ground-based gravitational wave interferometers such as the Laser Interferometer Gravitational-wave Observatory (LIGO) are susceptible to ground shaking from high-magnitude teleseismic events, which can interrupt their operation in science mode and significantly reduce their duty cycle. It can take several hours for a detector to stabilize enough...

2017 One‐year seismic‐hazard forecast for the central and eastern United States from induced and natural earthquakes

We produce a one‐year 2017 seismic‐hazard forecast for the central and eastern United States from induced and natural earthquakes that updates the 2016 one‐year forecast; this map is intended to provide information to the public and to facilitate the development of induced seismicity forecasting models, methods, and data. The 2017 hazard model...
