How fast is the hotspot moving under Yellowstone?
Actually, the source of the hotspot is more or less stationary at depth within the Earth, and the North America plate moves southwest across it. The average rate of movement of the plate in the Yellowstone area for the last 16.5 million years has been about 4.6 centimeters (1.8 inches) per year. However, if shorter time intervals are analyzed, the plate can be inferred to have moved about 6.1 centimeters per year from 16.5 million years ago until about 8 million years ago, then slowed to 3.3 centimeters a year for the past 8 million years.
For perspective, fingernails grow at a rate of about 3.6 centimeters per year.

How hot is Yellowstone?
Yellowstone is a plateau high in the Rocky Mountains, and is snowbound for over six months per year. The mean annual temperature is 2.2°C (36°F), barely above the freezing point of water. However, Yellowstone is also an active geothermal area with hot springs emerging at ~92°C (~198°F) (the boiling point of water at Yellowstone's mean altitude) and steam vents reported as high as 135°C (275°F)...
When was the last time Yellowstone erupted?
The most recent volcanic activity at Yellowstone consisted of rhyolitic lava flows that erupted approximately 70,000 years ago. The largest of these flows formed the Pitchstone Plateau in southwestern Yellowstone National Park.

Is Yellowstone overdue for an eruption? When will Yellowstone erupt?
Yellowstone is not overdue for an eruption . Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. Even so, the math doesn’t work out for the volcano to be “overdue” for an eruption. In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between...
How much volcanic activity has there been at Yellowstone since the most recent giant eruption?
Since the most recent giant ( caldera-forming ) eruption 631,000 years ago, approximately 80 relatively nonexplosive eruptions have occurred. Of these eruptions, at least 27 were rhyolite lava flows in the caldera, 13 were rhyolite lava flows outside the caldera, and 40 were basalt vents outside the caldera. The most recent volcanic eruption at Yellowstone, a lava flow on the Pitchstone Plateau...
How big is the magma chamber under Yellowstone?
Yellowstone is underlain by two magma bodies . The shallower one is composed of rhyolite (a high-silica rock type) and stretches from 5 km to about 17 km (3 to 10 mi) beneath the surface and is about 90 km (55 mi) long and about 40 km (25 mi) wide. The chamber is mostly solid, with only about 5-15% melt. The deeper reservoir is composed of basalt (a low-silica rock type) and extends from 20 to 50...
What type of eruption will Yellowstone have if it erupts again?
The most likely explosive event to occur at Yellowstone is actually a hydrothermal explosion (a rock hurling geyser eruption) or a lava flow . Hydrothermal explosions are very small; they occur in Yellowstone National Park every few years and form a crater a few meters across. Every few thousand years, a hydrothermal explosion will form a crater as much as a few hundred meters across. Though the...
How do scientists know what’s going on beneath the ground at Yellowstone? Is Yellowstone monitored for volcanic activity?
Yellowstone Volcano is monitored for signs of volcanic activity. The Yellowstone Volcano Observatory (YVO) is a partnership between the U.S. Geological Survey (USGS), Yellowstone National Park, the University of Utah, the University of Wyoming, UNAVCO, the Montana Bureau of Mines and Geology, the Idaho Geological Survey, and the Wyoming State Geological Survey. YVO closely monitors volcanic...
What is the relationship between volcanism and the geysers and hot springs in Yellowstone?
Heat and volcanic gases from slowly cooling magma rise and warm the dense salty water that occupies fractured rocks above the Yellowstone magma chamber. That brine, in turn, transfers its heat to overlying fresh groundwater which is recharged by rainfall and snowmelt from the surface. Water boiling at depth below the surface is hotter than the temperature of boiling at the surface. If it rises...
