This digital three-dimensional fault-trace map is superior to traditional maps in terms of relative and absolute accuracy, completeness, and detail and is used as a basis for three-dimensional visualization. The location map of the study site of Denali Fault line in southwest Yukon. Note the elongate pattern that follows the fault. On the Denali fault, a simple model with large slip patches ﬁnds a maximum of 8.7 0.7 m of slip between the surface and 14.3 0.2 km depth. The Denali Fault is part of a complex zone of con-tinental deformation between the Aleutian megathrust and the Queen Char-lotte Transform. (mfd). The Denali and Totschunda Faults are located along the northeastern edge of the Wrangell Subplate. Image courtesy of the USGS. We map the 385-kilometer (km) long surface trace of the right-lateral, strike-slip Denali Fault between the Totschunda-Denali Fault intersection in Alaska, United States and the village of Haines Junction, Yukon, Canada. Witter, J.B., 2020. Tectonic setting. By the time Lewis and Clark arrived on the West Coast in 1805, it had been 105 years since the Cascadia Subduction Zone last ruptured, sending a large portion of the Pacific Ocean roaring toward the coast. The geology near the pipeline crossing showed older rocks on the north side of the fault that are side-by-side with younger rocks on the south s… Applying the Geologic Map The November 3 Denali Fault earthquake was preceded by the magnitude 6.7 Nenana Mountain earthquake on October 23. It's a Not chosen size geocache, with difficulty of 1, terrain of 1. It illuminates earthquake mechanics and hazards of large strike-slip faults. | PDF help | Geologic The few remaining Native Americans in the area spoke of the earth shaking and ocean rising to consume the land. The image is from http://pubs.usgs.gov/fs/2003/fs017-03/ . [Adrian M Bender; Peter J Haeussler; Geological Survey (U.S.),] Earthquake-induced landslides, sackungen, and unruptured Holocene fault scarps on the eastern Denali Fault were also digitized where they lay within the limits of air photo coverage. This National Park includes part of a massive mountain range more than 600 miles long. It began with thrusting on the previously unrecognized Susitna Glacier fault, continued with right-slip … Areas affected by liquefaction are largely confined to Holocene alluvial deposits, man-made embankments, and backfills. USGS map of topography and earthquakes associated with Denali fault in Alaska. The Denali Fault is a major intracontinental dextral (right lateral) strike-slip fault in western North America, extending from northwestern British Columbia, Canada to the central region of the U.S. state of Alaska.. The Denali-Totschunda fault is a major dextral (right lateral) strike-slip system, similar in scale to the San Andreas fault system. FOIA The fault is dextral. Eastern Denali Fault surface trace map, eastern Alaska and Yukon, Canada. The 2002 M7.9 Denali fault earthquake resulted in 340 km of ruptures along three separate faults, causing widespread liquefaction in the fluvial deposits of the alpine valleys of the Alaska Range and eastern lowlands of the Tanana River. Purdue University website on GPS research on Denali. Also, the details of the mechanics of uplift are of interest. (b) 2002 Denali Earthquake Sequence showing location of M6.7 Nenana Mountain Earthquake and M7.9 Denali Fault Earthquake and If the curvature is smaller than that what are the strain implications. PASADENA, Calif.- Geologists just back from a reconnaissance of the 7.9-magnitude Alaska earthquake of November 3 confirm that rupture of the Denali fault was the principal cause of the quake. Denali's Fault (GC10DJK) was created by Tundra-quad on 1/16/2007. Alaska Earthquake Frequency Map Alaska Offshore Subduction Fault Zone Map Alaska Earthquake Hazard Map Alaska Faults and Volcanoes The Denali Fault is located in Alaska's Denali National Park and to the east. Between 1912 and 2002 the level of recorded seismicity on this section of the Denali Fault was very low with the majority of earthquakes M > 4.5 occurring on thrust faults to the north or south . Eastern Denali Fault Surface Trace Map, Eastern Alaska and Yukon, Canada By Adrian M. Bender and Peter J. Haeussler . Alaska is a geographical marvel. Many tribes even left the region permanently. In 2002, the M 7.9 earthquake ruptured a portion of the Denali fault east of the park to produce a horizontal offset of up to 8.8 m (29 feet). Thick vegetation, along with complex glacial landforms, large braided rivers, and fault-parallel bedrock structure (e.g., bedding) obscure the Eastern Denali Fault's surface expression. Get this from a library! The azimuths of the eastern Denali fault and Totschunda fault, where they sub‐parallel each other east of the transfer zone, differ on average by 12 degrees.

Taken from http://people.arsc.edu/~kcarlson/Other/EQ.html . Is this a flower structure of some sort, or does some other architecture exist. Seventeen km of the fault trace, which broke through glacier ice, were not digitized in detail due to time constraints, and air photos missed another 10 km of fault rupture through the upper Black Rapids Glacier, so that was not mapped in detail either. The rupture of the snow provided a detailed, shall we3 say, striking, picture of the rupture trace. Figure 2 (bottom): Geologic map of part of the 2002 Denali Fault rupture near the Trans-Alaska Pipeline crossing in the Alaska Range. Note the push up in the background. Location. Points were digitized 4.3 m apart, on average, for the entire surface rupture. DENALI FAULT SYSTEM Hines Creek fault The McKinley and Hines Creek strands of the Denali fault system form the principal structural elements of the central Alaska Range. Early-stage exploration for geothermal energy resources along the Denali fault near Duke River, Yukon. | Western reports main page | Western Data Series reports | Download a free copy of the current version of Adobe Reader. Note the strong curvature of the topography and fault. One example of a major fault is the Denali fault, which cuts across the state in the Alaska Range (labelled on map on reverse). Image from http://pubs.usgs.gov/fs/2003/fs014-03/shakemap.html. The Denali fault is an active intraplate dextral strike-slip fault. This is a USGS produced shake map, which shows the relative magnitudes of ground shaking during the 2002 earthquake. Denali Fault. The more northerly Hines Creek fault appears to have a broadly arcuate trace across the study area, but the fault is exposed only locally. The Denali fault is an active intraplate dextral strike-slip fault.

The November 3, 2002, Mw7.9 Denali Fault earthquake produced about 340 km of surface rupture along the Susitna Glacier Thrust Fault and the right-lateral, strike-slip Denali and Totschunda Faults.
