It also is remarkably reliable, with very few installation and equipment issues. Near Divide, Colorado, just west of Colorado Springs, this station is a favorite because it’s very quiet, meaning it’s good at picking up attenuated signals from far-away earthquakes. Photo credit: Martin Palkovic for the CGS. It’s on a beautiful site well-situated to help locate earthquakes in that area as well as around Glenwood Springs. Station HAYD was installed in August of 2018 near Hayden, Colorado, west of Steamboat Springs. The land belongs to CSU and is home to a giant Doppler radome. Installed in February of 2020 near Greeley, Colorado, CHIL re-occupies the location of a temporary station that was part of a multi-year induced seismicity study. Station CHIL :: CSU-CHILL Weather Radar Station, CO :: Helicorder This is one of the most seismically active areas of the state with a combination of both tectonic and induced earthquakes. Located near Trinidad, Colorado, this station is used to monitor earthquakes in the Raton Basin along the Colorado/New Mexico border. Station T25A :: Trinidad, CO :: Helicorder The CGS has stations in some very beautiful locations but this is one of our favorites. This installation, finished in August of 2019, is a collaboration between CGS and Colorado State University (CSU) and was installed at the CSU Mountain Campus near Rocky Mountain National Park. Station MCSU :: CSU Mountain Campus, CO :: Helicorder A single line on the helicorder graph traces the ground motion for a 10-minute interval.Īll the seismometer clocks are synchronized with Coordinated Universal Time (UTC) NIST: UTC-6 hours is equivalent to Mountain Daylight Time (MDT) and UTC-7 hours is equivalent to Mountain Standard Time (MST). Listed here, each of our current stations has a link to its real-time helicorder trace of the vertical ground motion component. Since then, we have continued to expand and maintain the network of seismometer stations distributed around the state to monitor local, regional, and even global seismic activity. The CGS first acquired a number of permanent seismic stations that were spun off from the USArray program in 2010. See Bulletin 43 – Earthquake Potential in Colorado: A Preliminary Evaluation for a more detailed history of these early activities. SEISMAC STATIONS INSTALLThe Bergen Park station, at the time designated “GOL” by the World-wide Standardized Seismograph Network (WWSSN), was able to locate Colorado earthquakes to within 10 mi (15 km) of their epicenter.ĭuring a twenty-day period in July and August 1976, the CGS hired Micro Geophysics Corporation to install and operate a high-gain seismic array in the Elkhead Mountains to monitor microearthquake activity in that area. Green Geophysical Observatory at Bergen Park, Jefferson County, Colorado, 1967. That system was in continuous high-gain operation into the 1980s and was, during that time, the primary source of instrumental data on Colorado earthquakes. Green Observatory at Bergen Park, about 9 mi (14 km) southwest of Golden. Monitoring of slow crustal movements.The Colorado School of Mines first acquired and installed a single three-component seismograph in the Cecil H. Seismic stations for strong motion records on the ground and in man-made structures. Real-time waveforms from all over the world. Opportunities for you to host a seismometer in your private home, business, public building or school. The NEIC determines the location and size of all significant earthquakes worldwide, disseminates the information immediately, maintains an online database of seismic information, and performs research. NEIC - National Earthquake Information Center Distribution of Global Seismographic Network (GSN) stations in 2015.
