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. [19] 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 ...

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.

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.
Elsewhere, the active volcano of Kilauea in Hawaii had been erupting almost constantly from its eastern rift zone since 1983. Then in April 2018, its 35-year-long eruption ended.
Volcanoes within the Northern Cordilleran Volcanic Province are located along short northerly trending segments which in the northern part of the volcanic province are unmistakenably involved with north-trending rift structures, including synvolcanic grabens and grabens with one major fault line along only one of the boundaries (half-grabens).
