By daylight on 2nd June the activity of the Honokua flow had greatly diminished, and by 11:00 movement in it had essentially ceased.Īnother lava flow at Mauna Loa originated along rift fissures between altitudes of 2,380 m and 2,680 m late on 1st June or early on 2nd June. This flow destroyed several houses, a filling station, and the Hookena Post Office at the village of Pahoehoe, where it crossed the highway. The other flow poured rapidly westward from the vents between 2,740 and 3,050 meters altitude, and reached the ocean at 01:05 on 2nd June 2, having advanced 24 km in a little more than 2.5 hours. By early morning on 2nd June it had extended 16 km but was already stagnating. One flow erupted from a fissure between 3,050 m and 3,200 m altitude. The Honokua lava flow covered the 24 km from vent to the ocean, in less than 3 hours.ĭuring the first few hours of the eruption two rapidly moving flows began. The eruption lasted for 23 days, and produced a large volume of lava. A line of fountains occurred in the summit caldera, and extended about 2 km beyond the caldera margin into the southwest rift zone.Ī large and spectacular eruption from the southwest rift zone of Mauna Loa began on 1st June 1950. Mauna Loa volcano began erupting on 5th July 1975. The eruption finished on 15th April 1984. By 29th March, lava flows reach within 6.5 km of Hilo. This was followed by fissures opening on upper NE Rift Zone. Lava fountains were visible in Mokuaweoweo caldera. On 30th March 2010 Hawaii Volcano Observatory decreased the alert level at Mauna Loa volcano from yellow to green (the lowest level).Įarly on the morning of 25th March 1984, a magnitude 4 earthquake accompanied an eruption of Mauna Loa volcano. Inflation of Mauna Loa volcano stopped in late October 2009. On 5th October 2022 the summit of Mauna Loa was closed to climbers due to elevated seismic activity. Lava from the hills erupted about 100,000 years ago.Ī summit eruptiuon began at Mauna Loa Volcano at 11:30 pm local time on 27 November 2022 The features are the oldest exposed portions of Mauna Loa volcano, and have been placed in their location by landslides on Mauna Loa. These hills are located inland from Punalu`u, on the southern side of Mauna Loa volcano. Mauna Loa volcano looking towards Kilauea summit eruption. Mauna Loa volcano is spreading because its size is large compared to the thin basal layer. Mauna Loa volcano ended its longest historical period of inactivity with the eruption beginning on 27 November 2022. ![]() On the sea floor, it rises more than 17,000 m (56,000 feet).
