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.
Apart from the large volcanoes, several smaller volcanoes exist throughout the Northern Cordilleran Volcanic Province, including cinder cones which are widespread throughout the volcanic zone. Most of these small cones have been sites of only one volcanic eruption; this is in contrast to the larger volcanoes throughout the volcanic zone, which ...

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.
Denali (/ d ə ˈ n ɑː l i /), [5] [6] officially known as Mount McKinley, [7] is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. It is the tallest mountain in the world from base-to-peak on land, measuring 18,000 ft (5,500 m). [ 8 ]
The Denali Wilderness is a wilderness area within Denali National Park that protects the higher elevations of the central Alaska Range, including Denali. The wilderness comprises about one-third of the current national park and preserve—2,146,580 acres (3,354 sq mi; 8,687 km 2 ) that correspond with the former park boundaries before 1980.
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. Reports of earthquakes and volcano ...
Further research shows that very distant earthquakes reach and have effects upon the activities at Yellowstone, such as the 1992 7.3 magnitude Landers earthquake in California's Mojave Desert that triggered a swarm of quakes from more than 800 miles (1,300 km) away, and the 2002 7.9 magnitude Denali fault earthquake 2,000 miles (3,200 km) away ...
