Mauna Loa eruption 2022 – live: Video shows hot lava spewing 40 meters into the air amid Hawaii volcano’s first eruption in 38 years

Mauna Loa: The world’s largest active volcano erupts in Hawaii

Hawaii officials have released a new map of the Mauna Loa eruption, revealing the areas currently threatened by lava spewing from the world’s largest active volcano.

In an update Monday night, the US Geological Survey (USGS) said no populated areas were threatened, but officials would provide updates if the situation changed.

While residents may not be at risk from the lava, the Hawaii Department of Health is warning the public of risks for air quality hazards such as fog conditions, ash in the air and rising levels of sulfur dioxide.

Mauna Loa erupted for the first time in nearly four decades late Sunday night, triggering dozens of earthquakes greater than 2.5 on the Richter scale, one of which clocked in at 4.2.

According to the National Weather Service (NWS), the eruption on the state’s Big Island began at approximately 11:30 p.m. local time Sunday in Mokuaweoweo, the volcano’s summit caldera.

Footage from US Geological Survey (USGS) summit web cameras captured fountains of lava spewing from a long fissure and spreading across the caldera floor.

The rare double eruption is expected to draw visitors to catch a pair of volcanoes lighting up the sky

Hawai’i Volcanoes National Park shared a photo on the park’s social media page Monday that showed something not seen in nearly 40 years: Mauna Loa and Kilauea, a nearby volcano, erupting at the same time.

The rare double-eruption event, the park said, hasn’t happened since 1984, and the park expects that as the pair continue to seep lava — Kilauea has been erupting for more than a year — they’re likely to draw an influx of visitors to capture a shot of the burning horizon.

“Viewing areas along the Kilauea caldera before sunrise revealed a massive glow from the Mauna Loa caldera, Mokuʻāweoweo (13,677 ft. elevation) and a smaller lava lake at Halemaʻumaʻu (4,009 ft.) atop Kīlauea,” wrote on Monday, near the park shelter. 24 hours after the world’s largest active volcano began to erupt.

Visitors planning a trip to Hawaiʻi Volcanoes National Park should be prepared and stay informed, the park’s superintendent, Rhonda Loh, said in the post, noting that the park remains open.

Why didn’t Mauna Loa explode like Mount St Helens?

57 people died when Washington state’s Mount St Helens erupted in 1980, blasting more than 1,300 feet (400 m) from the top of the mountain. Steam, rock and volcanic gas explode upwards and outwards. A plume of volcanic ash rose over 80,000 feet (24,384 m) and rained down as far as 250 miles (400 km) away.

Hawaiian volcanoes like Mauna Loa tend not to have explosive eruptions like this.

That’s because their magma is hotter, drier and more fluid, said Hannah Dietterich, a research geophysicist at the US Geological Survey’s Alaska Volcano Observatory.

The magma in Mount St Helens tends to be stickier and traps more gas, making it much more likely to explode when it rises.

The gas in the magma of Hawaii’s volcanoes tends to escape, which is why lava flows down the side of their mountains when they erupt.

Hawaii’s volcanoes are called shield volcanoes because successive lava flows over hundreds of thousands of years build broad mountains that resemble the shape of a warrior’s shield.

Shield volcanoes are also found in California and Idaho, as well as Iceland and the Galapagos Islands. Alaska’s Wrangell-St Elias National Park has eight shield volcanoes including Mount Wrangell.

Volcanoes such as Mount St. Helens are called composite or stratovolcanoes. Their steep, conical slopes are built by eruptions of viscous lava flows and rocks, ash and gas. Japan’s Mount Fuji is another example of a composite volcano.

Mauna Loa’s eruption led to a rare double eruption event with nearby Kilauea

After news broke that the world’s largest active volcano, Mauna Loa, had begun erupting for the first time in nearly 40 years on Sunday evening, eyes quickly turned to neighboring Kilauea, hoping they might get a rare glimpse of a double burst event.

Those who had harbored their hopes of catching such a sight were rewarded early Monday morning when the skies were set ablaze by the two erupting volcanoes in Hawai’i Volcanoes National Park.

Kilauea, located just 21 miles away from the larger Mauna Loa, has been erupting for more than a year.

But it was the first time in 38 years that the pair of volcanoes erupted simultaneously this week, treating park visitors to a stunning – and rare – shot that was shared widely on social media.

Neither outbreak currently threatens homes or nearby infrastructure at this time, the park said, although state health officials warned of potential impacts on air quality.

Video shows hot lava spewing 40 meters into the air after the Mauna Loa eruption

The USGS recently released new video footage from the Northern Rift Zone on Mauna Loa that shows just how powerful the volcano’s first eruption in nearly four decades is.

On Tuesday around 11 o’clock, the agency captured an angle of one of the fissures that are active at the Hawaii volcano. In the footage, you can see a fountain of hot lava spewing into the air above the ground, which the researchers estimated to be between 35 and 40 meters high.

In another clip shared by the agency, a video shows an ‘a’ā lava flow several meters thick moving northeast.

See the clip below here.

Where is Mauna Loa?

Mauna Loa is one of five volcanoes that together make up the Big Island of Hawaii, which is the southernmost island in the Hawaiian archipelago. It is not the tallest (that title goes to Mauna Kea), but it is the largest and makes up about half of the island’s land mass.

It sits immediately north of the Kilauea volcano, which is currently erupting from its summit crater. Kilauea is known for a 2018 eruption that destroyed 700 homes and sent rivers of lava spreading across farms and into the ocean.

Mauna Loa last erupted 38 years ago. In written history dating back to 1843, it has erupted 33 times.

The Big Island is mostly rural and is home to cattle ranches, coffee farms and beach resorts. It is about 200 miles (320 kilometers) south of Hawaii’s most populous island, Oahu, where the state capital Honolulu and the beach resort of Waikiki are both located.

One month ago: Hawaii’s Big Island gets warning as huge volcano rumbles

Authorities warned Hawaii residents to prepare a month ago…

Hawaii officials are warning residents about Big Island that the world’s largest active volcano, Long Mountainsends signals that it may erupt.

Although an eruption is not imminent, scientists are on high alert due to a recent increase in earthquakes at the volcano’s summit. Experts say it will only take a few hours for lava to reach homes closest to the volcano, which last erupted in 1984.

Mauna Loa: What you need to know

Mauna Loa is one of five volcanoes that together make up the Big Island of Hawaii, which is the southernmost island in the Hawaiian archipelago.

Rising 13,679 feet (4,169 meters) above sea level, Mauna Loa is Kilauea’s much larger neighbor, which erupted in a residential neighborhood and destroyed 700 homes in 2018. Some of its slopes are much steeper than Kilauea’s, so lava can flow much faster when it erupts.

During an eruption in 1950, the mountain’s lava traveled 15 miles (24 kilometers) to the sea in less than three hours.

How many people are at risk?

While there is no immediate danger to communities on Hawaii’s Big Island, officials have warned residents to be prepared for the worst.

Many current residents did not live there when Mauna Loa last erupted 38 years ago. The US Geological Survey warned the roughly 200,000 people on the Big Island that an eruption “can be very dynamic, and the location and advance of lava flows can change rapidly.”

The eruption began late Sunday night after a series of fairly large earthquakes, said Ken Hon, the scientist in charge at the Hawaiian Volcano Observatory.

There has been a surge of development on the Big Island in recent decades – its population has more than doubled from 92,000 in 1980.

Most of the people on the island live in the city of Kailua-Kona to the west of the volcano, which has about 23,000 people, and Hilo to the east, with about 45,000. Officials were most concerned about several subdivisions about 30 miles south of the volcano, which is home to about 5,000 people.
