Is Valles Caldera still active?
The Valles Caldera is a supervolcano eruption, like Yellowstone, and one of the largest young calderas on Earth. It formed about 1 million years ago when multiple explosive eruptions occurred that produced an immense outpouring of ash, pumice, and pyroclastic flows. It is considered by geologists to be still active.

Can calderas still erupt?
Unlike Mount Mazama, the Deception volcano is still active. The Deception volcano experienced a violent eruption roughly 10,000 years ago that caused its summit to collapse and flood with seawater, forming a caldera about 7 kilometers (4.4 miles) wide.
Is Valles Caldera felsic?
Caldera-forming eruptions are felsic eruptions and would produce massive amounts of ash that could reach a great distance from the source of the eruption.
How big is the Yellowstone caldera?
30 x 45 miles
What is the caldera shown on the park map? The Yellowstone caldera was created by a massive volcanic eruption approximately 631,000 years ago. Later lava flows filled in much of the caldera, now it is 30 x 45 miles.

What do all calderas have in common?
Most calderas—large circular or oval depressions more than 1 km (0.6 mile) in diameter—have been formed by inward collapse of landforms after large amounts of magma have been expelled from underground. Many are surrounded by steep cliffs, and some are filled with lakes.
