1 – La Garita Caldera
Garita Caldera is a large supervolcanic caldera in the San Juan volcanic field in the San Juan Mountains near the town of Creede in southwestern Colorado United States. The eruption that created the La Garita Caldera is among the largest known volcanic eruptions in Earth’s history.
How big is the hotspot under Yellowstone?
How far down does the magma plume reach under Yellowstone?
The 45-mile-wide plume that rises through Earth’s upper mantle from at least 410 miles beneath the surface. The plume angles upward to the east-southeast until it reaches the colder rock of the North American crustal plate and flattens out like a 300-mile-wide pancake about 50 miles beneath Yellowstone.
How far would the lava go if Yellowstone erupted?
The eruption could be expected to kill as many as 90 000 people immediately and spread a 10-foot (3-meter) layer of molten ash as far as 1 000 miles (1 609 kilometers) from the park.

What happens if Mt St Helen erupts?
If Mount St. Helens reawakened violently an ash plume reaching 30 000 feet (about 9 100 meters) or more could materialize in as little as five minutes grounding aircraft and wreaking havoc on agriculture water and power supplies and human health Ewert said.
What is the biggest supervolcano on Earth?
The largest (super) eruption at Yellowstone (2.1 million years ago) had a volume of 2 450 cubic kilometers. Like many other caldera-forming volcanoes most of Yellowstone’s many eruptions have been smaller than VEI 8 supereruptions so it is confusing to categorize Yellowstone as a “supervolcano.”
How many Supervolcanoes are in the US?
How many Supervolcanoes are in the world?
There are about 12 supervolcanoes on Earth — each one at least seven times larger than Mount Tambora which had the biggest eruption in recorded history. If all of these supervolcanoes erupted at once they’d likely pour thousands of tons of volcanic ash and toxic gases into the atmosphere.
What would happen if Taupo erupted?
“If Taupo were to erupt we would expect to see major ground deformation and thousands of earthquakes not hundreds ” Jolly says. White Island’s 2000 eruption followed a long period of activity and is one of “a couple” of eruptions Jolly has seen. Even that eruption though was “effectively a burp” she says.
How loud would Yellowstone be?
It was loud enough to deafen people within 100 km and was detectable on barometric pressure sensors around the globe. In fact the shockwave circled the globe 7 times before it faded to below detection.
How large is the Yellowstone volcanic caldera?
80 kilometers long
The huge crater known as a caldera measured as much as 80 kilometers long 65 kilometers wide and hundreds of meters deep extending from outside of Yellowstone National Park into the central area of the Park (see map in question above for location information).
What is the hot spot?
Mobile WiFi hotspots
Did you know that you can use your iPhone or many Android smartphones as a WiFi hotspot? By turning on this feature your phone uses its cellular data to create a WiFi hotspot. You can then connect a computer or other device to this hotspot to access the internet.
How did the Yellowstone hot spot form?
How often do Supervolcanoes erupt?
Geologists think these eruptions take place about every 50 000 years which suggests one is overdue. About 40 supervolcanoes are dotted across the globe.
Is the Hawaiian hotspot still active?
How long until the Yellowstone volcano erupts?
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 eruptions. That being the case there is still about 100 000 years to go but this is based on the average of just two numbers which is meaningless.
What is found 250 miles below the surface of Yellowstone?
The researcher discovered an anomalous structure about 250 to 400 miles beneath the line of Yellowstone volcanoes. Professor Zhou said: “This evidence was in direct contradiction to the plume model.”
