The Earthquake Hazards Program, part of the U.S. Geological Survey, shows the fau...The major divisions of geologic time (stratigraphic age) are represented with the RGB equivalent of the CMYK color specifications presented in the FGDC Digital Cartographic Standard for Geologic Map Symbolization. Faults are represented with a solid (fault location accurate), dashed (fault location approximate) or dotted (concealed fault) line.Earthquake hazard is the likelihood of a certain level of shaking—also known as Peak Ground Acceleration —that may occur from an earthquake in a particular area. Colorado has low-to-moderate earthquake hazard as rated by the U.S. Geological Survey Earthquake Hazards Program. Earthquake risk is the likelihood of economic or personal loss ...Regional topographic relief map of southern Idaho with recordedearthquakes M > 4:5 and aftershocks from the M w 6.5 Stanley earthquake. Quaternary-active faults are from the ... and thick blue line represents a 70° west-dipping fault that best fits the aftershock locations. Only earthquakes highlighted as red circles on (b) are included in Heavy lines are faults. Normal faults have ball and bar on down-thrown block. Thrust faults have sawteeth on upper plate. From Shoshone County map of the Digital Atlas of Idaho. Ymiu = Belt Supergroup; Kis = Cretaceous intrusive rocks; Ts = Tertiary sediments. Figure 4. Generalized geology of the Coeur d’Alene district. Yp, Yra, Yc, Ymil. Take a look at the map of most recently active faults in Idaho. Turn off the appropriate layers to clearly view just the Quaternary and Holocene faults. The Quaternary faults have been active since Pleistocene time. The Holocene faults have been active in the past 15,000 years and represent neotectonic crustal activity. Print the handout below.The new Ogden map fills a hole between similar 30′ x 60′ geologic maps to the north (Logan), south (Salt Lake City), and east (Kemmerer and Evanston, Wyoming). Fortunately for Utah, Jim Coogan, who had mapped similar terrain for his Ph.D., was available to map most of the quadrangle and, as a bonus, had access to energy-boom data.A fault is a three-dimensional surface within the planet that might extend up to the surface or might be completely buried. In contrast, a fault line is where the fault cuts the Earth's surface… if indeed it does. The most prominent faults in each state are usually shown on a state's geologic map as black lines.This map shows areas of seismic risk from high (red) to low (grayish-green). The map is from a 2007 report (click here to download) on seismic design categories in Washington. The map also shows potentially active faults from a separate 2014 report (click here to download). Earthquakes occur nearly every day in Washington. Most are too small to be …fabric, mainly characterized by steep-gradient, elongate magnetic lows, which overlie major ductile. thrust faults (Sims and others, 2004). Judged from aeromagnetic data, the deformed northwest margin of the Wyoming province. extends southwestward from Wyoming into Idaho.The Pacific Northwest is an area created by active and complex geological processes. On its path to the Pacific Ocean, the Columbia River slices through a chain of active volcanoes located along the western margin of the U.S. in Washington, Oregon, and northern California. These volcanoes rest above the active Cascadia subduction zone, …We present high-resolution mapping and surface faulting measurements along the Lost River fault (Idaho-USA), a normal fault activated in the 1983 (Mw 6.9) earthquake. The earthquake ruptured ~35 ...

Previous maps of the fault (e.g., Fischer et al. 1992; Kiilsgaard et al., 2006; USGS, 2023) depict the Sawtooth fault as a 60-km-long sinuous surface trace. Our new mapping shows the fault in greater detail, demonstrating a significantly more complex fault zone than ...…
