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 Fault is caused by stresses created by the low-angle subduction of the Yakutat microplate underneath Alaska. The Denali Fault Bend is characterized as a gentle restraining bend. [15] 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 ...
To the west, the Denali Fault is the source of minor earthquakes that extend along the length of the fault. [11] In contrast to the Tintina Fault, strike-slip movement along the Denali Fault has offset at least 370 km (230 mi) of the surface. [11] The fault separates mountains of the Insular Belt from mountains east of the fault. [11]
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
Reports of earthquakes and volcano eruptions along the Ring of Fire might lead some to believe that the level of activity in recent months is above average.
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 ...
Mount Kilauea, the most active volcano in Hawaii, has seen the number of earthquakes at its summit double over the past week, according to the U.S. Geological Survey. The summit region had gone ...
