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 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 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 139 deaths.
The U.S. Geological Survey said the first and more powerful quake was centered about 7 miles north of Anchorage, Alaska's largest city. Back-to-back earthquakes shatter roads and windows in Alaska ...
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]
Earthquakes are most common along fault lines, which are fractures that allow the plates to move. ... Earthquakes are also likely in California and Alaska, which are historically seismically ...
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.
In 1964, a massive 9.2 magnitude earthquake in Alaska resulted in a tsunami in Crescent City, California five hours later. The quake's epicenter was 1,600 miles from the town.
