What Are the Four Active Volcanoes Closest to Anchorage, Alaska?

Anchorage is Alaska's capital city and the most populous metropolitan area in the state. It is located near a geologically active area in the northern Pacific Ocean called the Pacific Ring of Fire, along the Alaska Peninsula and the Aleutian Arc. The four active volcanoes that are the closest to Anchorage are collectively known as the Cook Inlet Volcanoes.
  1. Mount Spurr

    • Mount Spurr is located about 80 miles west of Anchorage, and has a peak of more than 11,000 feet. Its series of three eruptions in 1992 resulted in the ejection of a significant amount of smoke and ash from its south vent, which was deposited on the city and surrounding areas. The eruption caused the Anchorage International Airport to close, disrupted air travel in the surrounding skies and disrupted the flow of ground traffic. Prior to 1992, Mount Spurr last erupted in 1953.

    Mount Redoubt

    • The eruptions from Mount Redoubt between 1989 and 1990 caused a significant disruption to air traffic. During one eruption, a Boeing 747 passenger jet with more than 200 people lost all four of its engines and fell more than 9,000 feet, before regaining power to its engines. This eruption affected air traffic as far away as Texas, damaged five aircraft and caused school closures due to its heavy clouds of falling ash.

    Mount Iliamna

    • Mount Iliamna last erupted in 1978, sending a cloud of steam nearly two miles high into the sky. Situated west of the Aleut village of Ninilchik, Mount Iliamna is a cone volcano with a summit more than 10,000 feet tall. This volcano is about 180 miles southeast from Anchorage, and is located at the end of the continental chain of the Cook Inlet Volcanoes. Before 1978, the last eruption of Mount Iliamna was in 1952.

    Mount Saint Augustine

    • Mount Saint Augustine is the youngest and smallest of the Cook Inlet Volcanoes. It stands more than 4,000 feet tall and is 15,000 years old. Mount Saint Augustine had a memorable eruption in 1986 that caused disruption of air traffic and travel for days due to the ash clouds it produced. Prior to this event, Mount Saint Augustine erupted violently in 1976.
