Where is caldera mostly found?
Pacific Ocean
Most are located around the Pacific Ocean in what is commonly called the Ring of Fire. A volcano is defined as an opening in the Earth’s crust through which lava, ash, and gases erupt. The term also includes the cone-shaped landform built by repeated eruptions over time.
What is the distance across the Yellowstone caldera?
The third and most recent massive volcanic eruption 640,000 years ago created the present 30- by 45-mile-wide Yellowstone Caldera.
Is the Long Valley caldera active?
The caldera remains thermally active, with many hot springs and fumaroles, and has had significant deformation, seismicity, and other unrest in recent years. A robust geothermal system inside the caldera fuels the Casa Diablo power plant, which generates enough power for 40,000 homes.
Is Taal caldera?
Taal volcano is in a caldera system located in southern Luzon island and is one of the most active volcanoes in the Philippines. It has produced around 35 recorded eruptions since 3,580 BCE, ranging from VEI 1 to 6, with the majority of eruptions being a VEI 2.
Will Long Valley caldera erupt again?
The pattern of volcanic activity over the past 5,000 years suggests that the next eruption in the Long Valley area will most likely happen somewhere along the Mono-Inyo volcanic chain. However, the probability of such an eruption occurring in any given year is less than 1%.
Is Apolaki Caldera active?

How big are the calderas in the US?
Calderas vary in size from one to 100 kilometers (0.62 to 62 miles) in diameter. Some calderas form a lake as the bowl-shaped depression fills with water. A famous example is Crater Lake, in Oregon. This caldera formed about 7,000 years ago when a stratovolcano, Mt. Mazama, violently erupted.
How tall is the dome of the Long Valley Caldera?
The elevation of the bottom of the bowl ranges from 6,500 to 8,500 ft (2,000 to 2,600 m), being higher in the west. Near the center of the bowl, there is a resurgent dome formed by magmatic uplift.
Which is the best description of a caldera?
Another type of caldera is a resurgent caldera. These broad, vast calderas result when very large magma chambers empty quite forcefully, causing a series of pyroclastic flows. Over time, the refilling of the magma chamber pushes up the caldera floor.
Is the Yellowstone Caldera in Yellowstone National Park?
Hike/auto/bus. The Yellowstone Caldera is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States, sometimes referred to as the Yellowstone Supervolcano.
