The Apolaki Caldera is a volcanic crater with a diameter of 150 kilometers (93 mi), making it the world’s largest caldera. It is located within the Benham Rise (Philippine Rise) and was discovered in 2019 by Jenny Anne Barretto, a Filipina marine geophysicist and her team.
Is Yellowstone the largest caldera in the world?
The circular depression on the Benham Rise is surrounded by a crest with scarps as high as 100 to 300 meters (300 to 900 ft). It may be the world’s largest known caldera with a diameter of ~150 km (93 miles). For comparison, the famous caldera of Yellowstone in Wyoming is only about 60 km (37 miles) wide.
Is Apolaki Caldera dangerous?
The volcano that gave rise to the Apolaki caldera, the world’s largest, poses no danger of erupting, PHIVOLCS director Renato Solidum said on Tuesday. … According to Barretto, the Apolaki caldera was formed by an underwater volcano, and it has a diameter of 150 km.
How many calderas are there in the world?
“Once you get enough melt, you can start an eruption just like that.” There are about 20 known supervolcanoes on Earth – including Lake Toba in Indonesia, Lake Taupo in New Zealand, and the somewhat smaller Phlegraean Fields near Naples, Italy. Super-eruptions occur rarely – only once every 100,000 years on average.
What is massive caldera?
A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. … The ground surface then collapses downward into the emptied or partially emptied magma chamber, leaving a massive depression at the surface (from one to dozens of kilometers in diameter).
Is Taal Volcano a supervolcano?
The Philippines has an active volcano too. It is one of the well-known and visited touristic place of the whole archipelago. The smallest supervolcano that has formed on the planet 500 000 years ago. … Taal Volcano is one of the most active volcanoes in the world.
What volcano could destroy the world?

Would we all die 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.
What is the most dangerous volcano in the world?
A recent PBS documentary identified Kilauea, on the island of Hawaii, as “The Most Dangerous Volcano in the World.” A curious choice, in my opinion, for any rating of a volcano’s danger must take into account both the intrinsic hazard and the number of lives at risk. Eruptions of Kilauea are certainly spectacular.
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.
Can caldera erupt?
Depending on their intensity and duration, volcanic eruptions can create calderas as much as 100 kilometers (62 miles) wide. A caldera-causing eruption is the most devastating type of volcanic eruption. It permanently alters the environment of the surrounding area.
How hot is a caldera?
At 80 kilometres beneath the Earth’s surface it’s about 1450 °C, say researchers – which, for a supervolcano, is only lukewarm. That doesn’t mean we won’t get another eruption. The last explosion, some 642,000 years ago, created the Yellowstone caldera and blanketed half of the present day US in ash.
Is a caldera a volcano?
A caldera is a volcanic feature formed by the collapse of a volcano into itself, making it a large, special form of volcanic crater. A caldera collapse is usually triggered by the emptying of the magma chamber beneath the volcano, as the result of a large volcanic eruption.
