Mount Redoubt Facts

Mount Redoubt is a volcano in Alaska that has been in the news lately given its active nature. In this article, we sum up the known Mount Redoubt facts you need to know.

Mount Redoubt has been in the news because it has been erupting regularly and with great ferocity. It has proven particularly interesting as it appears to be part of a world wide increase in geological activity with massive plate movements that have given rise to tsunamis and earthquakes along the ring of fire that stretches around and through the Pacific Ocean. Okay, let’s look at some Mount Redoubt facts.


Mount Redoubt is an unusually active volcano by most measures. It has significantly erupted five times in the last 110 years. The specific years are 1902, 1922, 1966, 1989 and 2009. The 1989 eruption gained fame for two specific reasons. First, it was the first eruption that was ever successfully predicted before hand. Second, two planes flew through the ash and nearly crashed, which gave rise to the realization that ash could negatively effect airplane engines. Since then, planes have been routed around ash paths from volcanoes worldwide.

Let’s take a look at the geological figures surrounding the volcano. It is roughly 3.7 miles in diameter and has a height of 11,413 feet as of the last eruption. This changes with each eruption as the height increases as the mountain expands and then decreases when it blows its top and removes a certain amount of material if the particularly eruption is strong enough.



It is part of the Aleutian Range running through Alaska and is considered part of the Chigmit Mountains. It is located just west of Cook Inlet and is roughly 100 plus miles from the city of Anchorage, Alaska. The volcano has a crater that it erupts from unevenly. The latest eruption was out of the northern face of the crater.

Mount Redoubt is one of the more famous volcanic locations in the scientific community. Its continued activity has allowed for a massive amount of research and study, which has greatly increased our understanding of how volcanoes work.
