Mauna Loa eruption, what happened inside the world's largest volcano?

Mauna Loa - the world's largest active volcano - exploded for the first time since 1984.

Lava temperatures of 1,000 degrees Celsius are pouring out next to the volcano, but some experts explain this has not given rise to great terror for residents on the spot.

How big is Mauna Loa mountain?

Mauna Loa, which means "long mountain" in Hawaiian, is the largest active volcano in the world.

Its area covers 5,271 sq km and as one of a series of five volcanoes that make up the Great Island of Hawaii.

This volcano alone covers 1/2 of all the islands.

Mauna Loa shoots exist at an altitude of 4,170 mtr. At sea level, but the bottom is on the bottom of the sea. The distance from the base to the top is 9,179 mtr., meaning Mauna Loa is getting higher than Mount Everest.

Why does Mauna Loa erupt?

The superheated material plumes mentioned by magma are already abundant beneath Mauna Loa and the surrounding volcanoes from "hotspots" deep in Earth.

"No one knows exactly why this hotspot exists," said Dr Carmen Solana, a volcanologist at the Portsmouth Campus, England, "but it was likely caused by the decay of radioactive material in the Earth's mantle.

"This plume of magma makes up all of the Hawaiian Islands."

When Mauna Loa exploded, Dr Solana said, magma was first in the caldera - a bowl-shaped hole at the top of a volcano. Mokuaweoweo mentioned that the caldera covers a place 15 sq km wide and 180 mtr deep.

Magma then gushes out in the rocks, next to the volcano, and down the mountainside. The magma that has come out on the earth is mentioned lava. At 1,000 C, he burned everything that was in his path.

When volcanoes explode, they emit cooling material to create the broken glass that Pele's Hair mentioned.

"Pele is the name of a goddess who is believed to live in Mauna Loa, and the fragments are thin and brownish gold," dr Solana said.

"The goddess has blonde hair and likes to be furious."

Why is the Mauna Loa eruption important?

Mauna Loa has exploded 33 times since 1843, which is called the time of the first registered eruption. That's an average of one eruption every five 1/2 years.

However, the mountain exploded almost 40 years ago.

"There have been many signs of magma increase over the past 10 years," said Andrew Hooper, a professor of geophysics at the Leeds Campus in England, "but there hasn't been an eruption until now."

The current Mauna Loa eruption gives a new batch of researchers the opportunity to learn the pace of the volcano's work, Professor Hooper said.

"It would be tempting to witness where the magma is placed in Mauna Loa - where it exists after it overflows from Earth's mantle and the moment before it exits the surface of the volcano," he said.

What eruption of Mauna Loa is at risk?

Unlike many other volcanoes, Mauna Loa generally does not produce the most explosive eruptions, in which lava soars into the air along with plumes of ash and gas.

In contrast, lava is pouring out at a fairly sluggish speed next to the volcano.

"Lava channels do not pose a threat to life," professor Hooper said, "because you can avoid them.

", lava does not pour westward towards some of the closest cities, but towards the northeast. He'd have to travel a fair amount of distance to that before he did serious damage to the property."

However, the gas released by Mauna Loa is likely to be more risky for residents on the spot.

"Volcanic gases, counting sulfur dioxide and chlorine react, with water vapor in the air produce 'vog', which is volcanic fog," dr Solana said.

"This can cause problems for some people if they are caught in the wind. Volcanic fog can cause eye irritation and respiratory problems for some people."

Health authorities in Hawaii say air quality is still good, but it can get worse at any time.

When that happens, on-site residents are encouraged to avoid outdoor activities and still remain indoors with windows and doors closed.
