What would happen if Tamu Massif erupted?
What would happen 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 largest volcano on Earth?
The discovery of Tamu Massif, a gigantic volcano located about 1,000 miles east of Japan, made big news in 2013 when researchers reported it was the largest single volcano documented on earth, roughly the size of New Mexico.
When was Tamu Massif last active?
Tamu Massif became extinct sometime during the Early Cretaceous period, which ended 100 million years ago, meaning it “died” just a few million years after it was born.
Can Tamu Massif erupt again?
A study found that the Moho line, the boundary between the Earth’s crust and mantle, extends more than 30 kilometres (19 mi) beneath the base of Tamu Massif, meaning that the volcano is unlikely to ever erupt again, since magma is presumably unable to penetrate a barrier that thick.
What is the deadliest volcano in the world?
Deadliest Eruption
| Deaths | Volcano | When |
|---|---|---|
| 92,000 | Tambora, Indonesia | 1815 |
| 36,417 | Krakatau, Indonesia | 1883 |
| 29,025 | Mt. Pelee, Martinique | 1902 |
| 25,000 | Ruiz, Colombia | 1985 |
Which volcanoes can erupt violently?
Because they form in a system of underground conduits, stratovolcanoes may blow out the sides of the cone as well as the summit crater. Stratovolcanoes are considered the most violent.
What is the most powerful volcano ever?
Mount Tambora — Indonesia, 1815 Mt. Tambora—which is still active—holds rank in its own category: the most explosive volcanic event ever recorded by humans.
When did Garita last erupt?

|---|---|
| Parent range | San Juan Mountains |

| Mountain type | Caldera |
| Last eruption | 26.3 Ma (Fish Canyon Tuff 27.8 Ma) |
What’s the biggest underwater volcano?
Scientists discovered the 2,690-foot-tall (820 meters) volcano in the western Indian Ocean, off Madagascar, following a puzzling spate of earthquakes that struck near what is normally a seismically quiet area.
Can lava burn in water?
Contact with lava underwater will certainly burn what it touches, due to the heat, and the heat can cause the water to reach boiling temperatures (for a time). But lava underwater is also cooling off pretty quickly, and turning to rock.
What’s the biggest active volcano in the world?
Mauna Loa
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.
What type of volcano is the Tamu Massif?
Dubbed ‘The Tamu Massif’, it is located about 1,600 km (1,000 miles) east of Japan, and is the largest feature of an underwater mountain range called Shatsky Rise. Reports noted the unusual shape of the huge lava deposit. It’s low and broad, a shield volcano. Most other volcanoes that erupt under the ocean are small with steep sides.
How does Tamu Massif interact with its surroundings?
Tamu Massif is located at a spreading ridge triple junction—the point where the boundaries of three tectonic plates meet. How the volcano interacted with this geological feature—also a type of volcano—was unclear.
What is the size of Tamu?
The main part of Tamu’s rounded dome extends over an area of 450 km × 650 km (280 mi × 400 mi), totaling more than 292,500 km 2 (112,900 sq mi), many times larger than Mauna Loa, which has an area of 5,000 km 2 (1,900 sq mi), and about half the area of the Martian volcano Olympus Mons. The entire mass of Tamu consists of basalt.
Could Tamu Massif have caused a magnetic field reversal?
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.
