What if Tamu Massif erupted?
Magnetic field reversals take place over thousands or millions of years, so if Tamu Massif had erupted in a single event, there would be no anomalies. However, an eruptive period that lasted far longer could have a record of a reversal. … Lava flows that travel long distances should destroy the magnetic stripes.”
Is Tamu Massif the biggest volcano?

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.

The Cuexcomate is known as “the smallest volcano in the world” and it is located just 15 minutes away from downtown Puebla in central Mexico. Discover the unexpected at this fascinating site inside the state capital of Puebla.
What if Yellowstone volcano erupted?
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.
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).

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?
