Tectonic map of Alaska and northwestern Canada showing main faults and historic earthquakes Denali Fault and the Denali National Park boundary. 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. In Alaska, moving from east to west, the plate interactions change from a transform boundary between the Pacific plate and North American plate to a collision zone with a microplate, the Yakutat terrane, which is in the process of being accreted to the North ...
The Totschunda Fault is a major active dextral (right-lateral) continental strike-slip fault in southeastern Alaska. It forms a link between the Denali Fault to the northwest and the Fairweather Fault to the southeast. The northwestern end of the fault ruptured during the 2002 Denali earthquake. [1]
The 1964 Alaska earthquake, also known as the Great Alaska earthquake and Good Friday earthquake, occurred at 5:36 PM AKST on Good Friday, March 27, 1964. [2] Across south-central Alaska , ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 131 deaths.
Note: The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand-alone articles. The principles described also apply to lists. In summary, only damaging, injurious, or deadly events and those of scientific interest should be recorded.
The Denali Fault Bend represents a curvature in the Denali Fault that is approximately 75 km long. This curvature creates what is known as a "space problem." As the right-lateral movement along the Denali Fault continues, high compressional forces created at the fault bend essentially push the crust up in a vertical fashion. The longer the ...
Four major rivers cross the Alaska Range, including the Delta and Nenana Rivers in the center of the range and the Nabesna and Chisana Rivers to the east. Alaska Range Glacier. The range is part of the Pacific Ring of Fire, and the Denali Fault that runs along its southern edge is responsible for many major earthquakes.
Susitna Glacier is an alpine or valley glacier in the Alaska Range. Susitna Glacier flows over a seismically active area. [1] The 7.9-magnitude 2002 Denali earthquake struck the region in November 2002. The earthquake initiated with thrust movement on the previously unrecognized Susitna Glacier fault. [2]
