No one living today can recall a volcanic eruption of such magnitude, or of such potential disruption to human safety and systems, and yet we know that many volcanic complexes in the United States and around the globe are capable of someday erupting similar or larger volumes of molten rock and ash.The site has been preserved since 1980 by the Katmai National Park and Preserve.

The Novarupta-Katmai eruption:
- Was ten times more forceful than the 1980 eruption of Mount St. Helens.
- Buried more than 40 square miles in volcanic deposits as much as 700 feet deep.
- Spewed 7 cubic miles of ash as far as the Mediterranean Sea.
- Caused an acid rain that disintegrated clothes on clotheslines as far away as Vancouver, Canada.
- Reduced visibility 100 miles away in Kodiak, Alaska where for two days a person could not see a lantern held at arm's length.
The volume of ash ejected by Novarupta-Katmai, if concentrated in one place, would be enough to bury the city of Anchorage 3 miles deep.
Volcanology is the study of volcanoes, lava, magma, and related phenomena. The term volcanology comes from the Latin word vulcanus.
In ancient Roman religion and myth, Vulcan is the god of beneficial and hindering fire, including the fire of volcanoes.
At the time of the Novarupta-Katmai eruption in 1912, the study of volcanic eruptions was in its infancy. Researchers had few points of comparison. Field investigations of the Katmai site provided key insights that contributed to advances in volcanology. Novarupta-Katmai has been one of the most studied eruptions in the world.
I have seen so many eruptions in the last 20 years that I don't care if I die tomorrow.
