Denver Basin Earthquake Study

Denver Basin Earthquake Study

Earthquake study in Denver Basin of Northeast Colorado


The Denver Basin Earthquake Study began with a rapid aftershock deployment of the June 1, 2014 UTC (May 31 local time) earthquake that occurred east of Greeley, Colorado. The earthquake was widely felt, with felt reports from as far as Golden and Sterling, Colorado, at 99 and 115 km distance, respectively. The deployment of seismometers to study the earthquake was led by a team from the University of Colorado Boulder.  The network started with five stations centered on the epicenter of the 2014 earthquake, and in 2016 the network was expanded to include a larger part of the Denver Basin. All data are send in real-time by cell phone modem to the University of Colorado Boulder, and from there transmitted to the USGS in Golden and the Incorporated Research Institutions for Seismology (IRIS) data management center in Seattle. Results from our research can be found here. All data are freely and immediately open to all.
