The world’s largest volcano, Mauna Loa in Hawaii, is a shield volcano, according to the U.S. Geological Survey. Mauna Loa is about 55,770 feet (17,000 meters) from its base beneath the ocean to the summit, which is 13,681 feet (4,170 meters) above sea level.
What are the 3 types of volcano?
There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.
What is the biggest volcano in history?
The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index. The volcano, which is still active, is located on Sumbawa Island and is one of the tallest peaks in the Indonesian archipelago.
What is the 2 biggest volcano in the world?
Mauna Loa is runner-up to Tamu Massif for the world’s biggest volcano. Also an enormous ocean volcano, Mauna Loa is one of five volcanoes on the Big Island of Hawaii.
Which is the most dangerous volcano in the world?
The quick answer: Vesuvius volcano in the Gulf of Naples, Italy. The reason is that Vesuvius’ typical eruptions are very explosive and the slopes of the volcano and immediate area surrounding the volcano are extremely densely populated; even the city of Naples is only about 20 km away from the volcano.
Which types of volcanoes are most dangerous?
Composite volcanoes are some of the most dangerous volcanoes on the planet. They tend to occur along oceanic-to-oceanic or oceanic-to-continental boundaries because of subduction zones. They tend to be made of felsic to intermediate rock and the viscosity of the lava means that eruptions tend to be explosive.
Will Yellowstone erupt 2020?
Yellowstone is not overdue for an eruption. … 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. If Yellowstone does erupt again, it need not be a large eruption.
What volcano could destroy the world?
The Yellowstone supervolcano — an 8 out of 8 on the Volcanic Explosivity Index — has erupted three times over the past 2.1 million years, most recently 640,000 years ago. A Yellowstone eruption would be like nothing humanity has ever experienced.
Which country has no volcanoes?
Even though Australia is home to nearly 150 volcanoes, none of them has erupted for about 4,000 to 5,000 years! The lack of volcanic activity is due to the island’s location in relation to a tectonic plate, the two layers of the Earth’s crust (or lithosphere).
Can we survive if Yellowstone erupts?
Should the supervolcano lurking beneath Yellowstone National Park ever erupt, it could spell calamity for much of the USA. Deadly ash would spew for thousands of miles across the country, destroying buildings, killing crops, and affecting key infrastructure. Fortunately the chance of this occurring is very low.
Can Yellowstone wipe out America?
1. Yes, it will! But the next eruption is likely to be pretty small, just a bit of lava extruding with maybe minor amounts of ash. … If the next enormous eruption happens in our lifetimes, there will of course be death and destruction, but not enough to destroy the United States, or even just the American West.

What is the most powerful volcano on Earth?
Rising gradually to more than 4 km (2.5 mi) above sea level, Hawaii’s Mauna Loa is the largest active volcano on our planet. Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa’s great mass another 8 km (5 mi).
