Is Old Faithful A Volcano?

Old Faithful is one of the most famous geysers in the world, located in Yellowstone National Park in the United States. Many people wonder if Old Faithful is actually a volcano, given its impressive eruptions and association with geothermal activity.

What is a Volcano?

A volcano is a vent in the Earth’s crust through which molten rock, ash, and gases are expelled. Volcanoes can be active, dormant, or extinct, depending on their level of activity. They are typically associated with tectonic plate boundaries and hotspots.

Old Faithful: Geyser or Volcano?

Old Faithful is not a volcano; it is a geyser. Geysers are hot springs that periodically erupt columns of water and steam into the air. Old Faithful is known for its predictable eruptions, which occur approximately every 60 to 110 minutes and can reach heights of up to 185 feet.

Geothermal Activity in Yellowstone

Yellowstone National Park is located on top of a supervolcano, which is a large volcano capable of producing massive eruptions. The park is known for its geothermal features, including geysers, hot springs, and mud pots. These features are fueled by the heat from the supervolcano beneath the Earth’s surface.


While Old Faithful is not a volcano, it is a fascinating example of geothermal activity in Yellowstone National Park. Its regular eruptions are a popular attraction for visitors to the park, and serve as a reminder of the powerful forces at work beneath the Earth’s surface.
