Mauna Loa Volcano Eruption Hawaii: USGS, Live, Flow Map of Hawaii and more Updates

Mauna Loa Volcano Eruption Hawaii, Hawaii’s Mauna Loa, the world’s biggest active volcano, has erupted for the first time in almost 40 years. The eruption on Sunday marks the end of its longest recorded quiet period since 1984.

Mauna Loa Eruption March 2023

At approximately 11:30 pm local time on Sunday (0930 GMT Monday), the summit of Hawaii’s largest island emitted bright, hot lava, causing the night sky to glow a fiery red. Fortunately, the lava is currently confined to the summit and is not posing a threat to those living downslope, according to the U.S. Geological Service (USGS).

Mauna Loa Eruption Update

As a precautionary measure, Hawaii’s Emergency Management Agency has opened two shelters on the island. However, the agency has also emphasized that there are no indications of lava posing a threat to populated areas, and as a result, it has not given any evacuation orders.

Rewritten: As of 1:30 PM, the eruption of Mauna Loa is ongoing on the Northeast Rift Zone. Three fissures erupted, with only the lowest one remaining active. The highest recorded fountain heights are estimated to be between 100-200 ft (30-60 m), while most are a few yards (meters) tall. The fissures have caused lava to flow to the northeast and parallel to the rift zone. The lava flows from the two higher fissures came to a halt about 11 miles (18 km) from Saddle Road after moving downslope. Currently, Fissure 3 is responsible for the lava flows moving east, parallel to the Northeast Rift Zone, at an elevation above 10,000 feet and over 10 miles (16 km) away from Saddle Road. There is no expectation of the upper fissures reactivating, but additional fissures could open along the Northeast Rift Zone below the current location, and lava flows can continue moving downslope.

As of now, there is no active lava in Moku’āweoweo caldera, and the Southwest Rift Zone is also not erupting. Therefore, we don’t anticipate any volcanic activity beyond the Northeast Rift Zone. Currently, no properties are under threat. However, there is a visible gas plume emerging from the fissure fountains and lava flows, which is mainly being carried towards the Northwest.

Mauna Loa USGS

According to a statement from the US Geological Service (USGS), there is currently no threat to downslope communities as the lava flows remain within the Northeast Rift Zone. The USGS also reported that Mauna Loa has erupted a total of 33 times since 1843, with the last eruption occurring in 1984, which brought lava within 4.5 miles of Hilo.

Mauna Loa, which means “long mountain” in Hawaiian, is aptly named as it stretches for about 74 miles from its base on the southern coast of Hawaii Island to the rim of its summit caldera, where the current eruption started on Sunday evening.
