    en.wikipedia.org/wiki/Denali_Fault

    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.

    en.wikipedia.org/wiki/2002_Denali_earthquake

    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 ...

    en.wikipedia.org/wiki/1964_Alaska_earthquake

    The Alaska earthquake was a subduction zone (megathrust) earthquake, caused by an oceanic plate sinking under a continental plate. The fault responsible was the Aleutian Megathrust , a reverse fault caused by a compressional force.

    The Salcha Seismic Zone is a fault line in the Interior region of Alaska, United States, generally located to the east of Fairbanks.The fault runs for 65 km (40 mi) from the northern edge of the Alaska Range across the Tanana Valley to the southern end of the Yukon–Tanana Uplands and is parallel to the Fairbanks and Minto Seismic Zones located further west.

    The major earthquake that struck on the Fairweather Fault had a moment magnitude of 7.8 and a maximum perceived intensity of XI (Extreme) on the Mercalli intensity scale. The epicenter of the quake was at latitude 58.37° N, longitude 136.67° W near the Fairweather Range , 7.5 miles (12.1 km) east of the surface trace of the Fairweather fault ...

  9. 1957 Andreanof Islands earthquake - Wikipedia

    Most of the trench ruptured in a sequence of earthquakes from east to west. [5] Earthquakes in 1938, 1946, 1948, and 1965 generally progressed westward with smaller earthquakes filling in any gaps. [5] At each terminus of the subduction zone, convergence ends in favor of right-lateral transform faults. [9]
