hazards, Hazards, earthquake, Earthquake, Focal mechanisms for the mainshock and aftershocks have NE-SW-trending T axes, a feature shared by most earthquakes in western Colorado and by the induced Denver earthquakes of 1967.

These will include notices for new blog entries, new publications, and the occasional geoscience event or news item of note. The shaded oval on the map is is the felt area of the largest after-shock. Earthquake magnitude is estimated at 6.2 0.3 ML, based on felt area size.

These estimates may be used by local, state and regional officials to 1) plan and stimulate risk-reduction efforts and 2) to prepare emergency response and recovery action plans. Denver. It was felt over 470,000 km, with a maximum reported Modified Mercalli intensity of VII. Kirkham, Robert M., and William P. Rogers. More than one century later, on 18 October 1984, an mb 5.3 earthquake occurred in the Laramie Mountains, Wyoming. This after shock was used to pinpoint the likely location of the main shock, plus or minus 50 km. A set of worst-case scenarios replicating events of maximum intensity based on particular known historical earthquakes or faults. The possibility of there having been two earthquakes closely spaced in time at different locations was specifically addressed and no data supporting this theory was found. earthquake, 1.0 km and to have ruptured ?? Knowledge of its size, location, and specific tectonic environment is important for the design of critical structures in the rapidly growing region of the Southern Rocky Mountains.
CO: Colorado Geological Survey, Department of Natural Resources, 1986. Denver, Colorado 80225. 1801 Moly Road The only data for the 1882 earthquake were intensity reports from a heterogeneously distributed population. Official websites use .gov Knowledge of its size, location, and specific tectonic environment is important for the design of critical structures in the rapidly growing region of the Southern Rocky Mountains. 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.
