What is the science behind Old Faithful?
The escape of the top layers of water decreases the pressure on the hotter waters below, causing a chain reaction of violent steam explosions that expand the volume of the rising, boiling water by 1,500 times or more. This superheated water then bursts into the sky to form a geyser’s familiar fountain.
What is special about the geyser Old Faithful?
Old Faithful is a cone geyser in Yellowstone National Park in Wyoming, United States. It was named in 1870 during the Washburn–Langford–Doane Expedition and was the first geyser in the park to be named. It is a highly predictable geothermal feature and has erupted every 44 minutes to two hours since 2000.
Does Old Faithful erupt every 90 minutes?
It’s in the name Old Faithful, the geyser in Yellowstone National Park that blows over a hundred feet in the air every 90 minutes or so. It’s enchanted millions of visitors for generations.
What makes Old Faithful explode?
Seismic records show that under the Yellowstone geyser, a large egg-shaped chamber is connected to the mouth of Old Faithful by a sort of pipe. After every eruption, water levels rise in the chamber and send steam bubbles into the conduit—which creates a “bubble trap” that leads to the eventual steam explosion.
How often does Old Faithful explode?
The famous geyser currently erupts around 20 times a day and can be predicted with a 90 percent confidence rate within a 10 minute variation. Prior to the 1959 earthquake, Old Faithful erupted 21 times per day.
What heats the water in Old Faithful?
Here’s what sets Old Faithful and other geysers off. A geyser is the product of heat, water, and some plumbing. The heat comes from partially molten rock, or magma. Underground water is supplied by rain and melting snow that seep through a vast system of cracks and fissures.
How was Old Faithful geyser formed?
Geysers like Old Faithful are only formed under specific conditions, making them relatively rare. Magma under the Earth’s surface superheats pockets of underground water, building pressure that eventually pushes the water upwards.

Will Old Faithful explode?
Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption.
Will Old Faithful ever stop erupting?
While the geyser is highly predictable – it has erupted every 44 to 125 minutes since 2000 – a new climate assessment and a recent study have revealed that rising temperatures, reduced snowfall and increased rain threaten to shut Old Faithful off completely by the end of the century.
How hot is the Old Faithful Geyser water?
204°F
At only 45 feet (14 m) inside Old Faithful’s throat, the water temperature is 244°F (117°C). Prior to an eruption, the water at the geyser’s vent is 204°F (96°C)—several degrees hotter than the area’s normal surface boiling point of 199°F (93°C).
