World's largest active volcano erupts in Hawaii

World's largest active volcano Mauna Loa, located in Hawaii, has erupted for the first time in nearly 40 years, spewing ash Monday morning that They do not, at this time, threaten nearby homes. The eruption began Sunday night at 11:30 p.m. local time (10:30 a.m. this Monday), according to the American Institute of Geophysics (USGS) in a message.

“The early phases of a Mauna Loa eruption can evolve rapidly and the location and progress of lava flows can change rapidly,” the Institute in its first note on Sunday. Winds could carry “volcanic gas and Pele's hair,” volcanic glass fibers.

The United States Weather Service (NWS, for its acronym in English) warned So volcanic ash could accumulate around the volcano.

Mauna Loa is 4,169 meters high. The volcano has erupted 33 times since 1843. The last one was in 1984 and it lasted for six months. 22 days.

The rash is over. It caused thick clouds of smoke atop the US island of Hawaii, the largest in the Pacific archipelago. The scrolls are visible for more than 70 kilometers.

Initially contained in the summit crater, lava is now flowing through fissures in Mauna Loa's flanks and specialists are closely monitoring the situation. The authorities have not ordered evacuations, but the area near the summit and some roads on the island are closed as a caution.

Several lava flows

“The Mauna Loa eruption has migrated from the summit to the northeast rift zone, where fissures are feeding several lava flows,” the USGS said on its website. .

Currently there is no risk to homes located below the eruption zone, according to the institute, which warns, however, of the volatility of this volcano, the largest in the world. It covers half the island of Hawaii and is larger than all the other islands in the archipelago combined.

“The early stages of a Mauna Loa eruption can evolve rapidly and the location and progress of lava flows can change rapidly,” Ward said. the USGS reported.

According to the institute, the winds could also carry “volcanic gas and Pele's hair,” volcanic glass fibers that They are named after the Hawaiian fire goddess, and which are formed when lava droplets are stretched into fine filaments by gusts of wind. Sharp, they are dangerous to skin and eyes.

Last eruption in 1984

The National Weather Service (NWS) of The United States has warned that volcanic ash and debris may accumulate around the volcano. This can cause breathing difficulties for residents or disrupt motors or electronic systems.

Mauna Loa, or “Long Mountain” in Hawaiian, hasn't erupted since 1984. lava flowed for 22 days, producing lava flows that reached just four miles from the city of Hilo, located northeast of the volcano.

“The fact that it is “A dangerous mountain that hasn't erupted since 1984 – the longest eruptive pause in its history – is the reason we all need to keep an eye on it,” said Dr. vulcanologist Robin George Andrews tweeted on Twitter.

The expert assured that he was not a fan. The lava flows escaping through the newly formed cracks on the northeast flank of the volcano represent “a new and dangerous dimension (of) the eruption,” he said. . But unless its flow increases dramatically, the city of Hilo and its 44,000 people should be safe.
