Hawaii’s Mauna Loa is erupting for the first time since 1984


The largest active volcano in the world, Long mountain First volcanic eruption in Hawaii in 40 years.

Although lava is flowing down one side of the volcano, the eruption at Hawaii Volcanoes National Park does not pose a threat to communities, the US Geological Survey said Monday.

“All indications are that eruptions will remain in the northeast rift zone,” the agency said. in council, refers to an area where a volcano is erupting, allowing lava to flow. “Volcanic gas and fine ash and Pele hair (threads of lava glass) can be carried downwind.”

The National Weather Service in Honolulu said parts of the island could get “up to a quarter-inch trace” of ash.

“Passengers with flights to Hilo International Airport (ITO) or Allison Onizuka-Kona International Airport (KOA) in Keyhole should check with the airline before traveling to the airport due to volcanic activity at Mauna Loa,” the statement said. giving advice with the state transport department.

Southwest Airlines will not operate Hilo International starting Monday due to the volcanic eruption, the airline said. It canceled five flights to and from Honolulu, Southwest said.

The US Federal Aviation Administration “is closely monitoring the eruption and will issue warnings to air traffic once the size of the ash cloud is determined,” the statement said.

The Hawaii Volcano Observatory has received reports of lava overflowing the southwest portion of the volcano’s caldera, or crater, the Hawaii Emergency Management Agency said in a tweet Monday morning.

Nearby settlements are not threatened and no evacuation orders have been issued, the agency reports. tweeted. Another agency tweeted that two shelters had been opened as a precaution, even as “about half” of Mauna Loa’s recorded eruptions had stopped threatening communities in the summit area.

Ash can damage vehicles and buildings, pollute water supplies, disrupt sewer and electrical systems, and damage or kill plants. says the weather serviceand abrasive volcanic ash irritates the eyes and lungs.

“People with respiratory conditions should stay indoors to avoid inhaling ash particles, and anyone outside should cover their mouth and nose with a mask or cloth,” the Honolulu office warned. “Potential damage to crops and animals. Minor equipment and infrastructure damage. Reduced visibility. A massive purge may be necessary.”

The observatory previously said the lava flows did not pose a threat to communities on the slopes.

At about 4,000 square miles, Hawaii, or the Big Island, is the largest in the Hawaiian chain, but has a population of over 200,000. US Census Bureau, or less than 50 people per square mile. Most of the population is in coastal cities and communities.

“Based on past events, the initial stages of a Mauna Loa eruption can be very dynamic and the location and progression of lava flows can change rapidly,” the observatory said.

“However, if the vents migrate outside its walls, lava flows can move rapidly downslope.”

Red hues from the eruption lit up the pre-dawn sky Monday, according to footage captured by Kailua Bay and the pier by Matthew Liano of Kailua-Kona, on the Big Island’s west coast.

“The shine is unlike anything I’ve experienced living in Kona for most of my life,” Liano told CNN.

The eruption began at 11:30 p.m. HST Sunday (4:30 a.m. ET Monday) at Moku’aweo, the summit caldera of Mauna Loa, according to the observatory.

Mauna Loa started erupting on Sunday.

Covering half of Hawaii, Mauna Loa has erupted 33 times since 1843, marking the volcano’s first “well-documented historic eruption.” According to the US Geological Survey. It last erupted in 1984, and this has been a long period of calm the longest in the history of the volcano.

Mauna Loa’s summit crater is located 21 miles west of Kilauea, a smaller volcano that has been erupting since 2021. Their simultaneous eruptions caused a rare double eruption event. park.

Kilauea’s eruption is currently confined to its crater. When Kilauea erupted Months of 2018it spewed lava and destroyed the Leilani Estates neighborhood More than 700 houses and relocation of residents.

Enter Mauna Loa increasing excitementThe agency noted in an update late last month that there was increased seismic activity and an increase in earthquakes.

According to the US Geological Survey, earthquake activity has increased from five earthquakes per day since June 2022 to 10-20 earthquakes per day in July and August. The highest number of more than 100 earthquakes per day was recorded on September 23 and 29. This was reported by CNN.

Activity has increased Hawaii Volcanoes National Park in October to cover the summit of Mauna Loa however, to all mountain hikers until further notice The US National Park Service said the main section the park remains open.
