In 1966, David Evans published a report linking the earthquakes with the Rocky Mountain Arsenal. ↑ USGS Colorado Earthquake History. A. Dietrich f. h,_ During the 1968 pumping tests at the Rocky Mountain Arsenal disposal well, the U.S. Geological Survey was responsible for moni­ wring earthquakes occurring in the area of the arsenal ami making chemical analysis of the fluids removed. Colorado experienced the nation's very first induced earthquake in 1962 at the Rocky Mountain Arsenal north of Denver. Within months, Denver residents were jolted by a series of earthquakes, including one of magnitude 4.8 that caused more than $1 million in damage. At 5.7 magnitude, the Prague earthquake was about 10 times stronger than the previous record holder: a magnitude-4.8 Rocky Mountain Arsenal earthquake … Pickett, Properties of the Rocky Mountain Arsenal Disposal Reservoir and Their Relationship to Derby Earthquakes, 63 Q. Colo. School Mines 73 (Jan. 1968). In 1967, an earthquake of magnitude 5.5 followed a series of smaller earthquakes. For example, at the Rocky Mountain Arsenal in Colorado, earthquakes continued for many years after injections stopped, due to the low‐permeability rock layer boundary (Healy et al., 1968). 0000007982 00000 n (A new plot … Earthquake, G.R. Then for no apparent reason from 1962-1965 there were over 1000 earthquakes some of which were as high as magnitude 4.6. But another important takeaway from this is this earthquake – this largest earthquake happened over a year after they stopped injection. 1801 Moly Road Injection had been discontinued at the site in the previous year once the link between the fluid injection and the earlier series of earthquakes was established. 0 How much economic loss would there be? 0000220101 00000 n First, the largest earthquake we saw associated with it was a magnitude 4.9, and there was some damage associated with it.

While the area had previously witnessed seismic events, this was extremely uncharacteristic. 0000006176 00000 n The estimates of social and economic impacts contained in these reports were produced using HAZUS loss estimation methodology software which is based on 2005 scientific and engineering knowledge. 0000004387 00000 n Travel approximately 2.8 miles to Prairie Parkway/64th Avenue. The simulations are based on either the Western US (WUS) or Central and Eastern US (CEUS) attenuation functions (see the USGS, A global summary report that tabulates losses based on the stated scenario conditions. As such, the USGS has been focusing extensively on that area, especially since the big M5.3 Raton Basin earthquake in 2011. To many people in the Denver Metropolitan Area this evidence solidified the correlation. “HA-84 HAZUS 2005: Rocky Mountain Arsenal Fault Earthquake Event Report.” Earthquake Simulation. According to the December 19, 1965, Denver Post, "Deep well pumping at Rocky Mountain Arsenal [may] be responsible for the Denver area earthquakes..." A theory supported by many of the nation's geologists held that the fluids being pumped into the ground via the Pressure Injection Disposal Well since 1962 acted as a lubricant, allowing large blocks of stone beneath the earth to shift more easily.
