There are several clusters of seismicity in the area that are well-known and studied in the area around Rocky Mountain House, Eaton added. The felt area information along with damage reports has been used to estimate a quake magnitude of 6.6 (plus or minus 0.6). In August 2014, a 4.3 magnitude earthquake struck in a similar location, she added. seismic information on the distant past before the Rocky Mountain region be- came populated. After an earthquake shook the area, researchers began tracking the volume of water injected into the ground and the resulting seismicity. A text abstract of this article is not available.

Title: The Denver Earthquakes Created Date: 20080404040404Z Only minor damage — if any — would be expected with an earthquake of this magnitude, said David Eaton, a professor with the Department of Geoscience at the University of Calgary. Rocky Mountain National Park In addition to potential movement along the Front Range, seismic activity also occurs in the volcanic formations on the northwest corner of the park. Local east-west movement of the Never Summer Range/Kawuneeche Valley faults created the valley and allowed the upward flow of the volcanic material that forms the Never Summers. These are the only known magnitude estimates of Phanerozoic (other than Quaternary) large‐intensity earthquakes for the Rocky Mountain region, and they are as large as, or larger than, previous estimates of Proterozoic earthquakes along these major shear zones of the central Rockies. By the end of December 1962, 190 earthquakes had occurred. These earthquakes occur within the thrust-fault systems associated with the ancient mountain-building processes that created the Rocky Mountains.
