New Webcam shows fissure 3!! https://www.usgs.gov/media/webcams/m5cam-mauna-loa-fissure-3-eruption-northeast-rift-zone Daily update: The Northeast Rift Zone eruption of Mauna Loa continues, with several fissures and lava flows active. Lava flows are traveling downslope in a northeast direction. Fissure 3 is the source of the largest lava flow, which crossed the NOAA Mauna Loa Weather Observatory Road at approximately 8 p.m. yesterday evening, November 29. The lava flow front was located about 6 miles (10 km) from Saddle Road at 7 a.m. HST this morning. Lava fountains at fissure 3 are up to 82 ft (25 m). Fisssure 4 began erupting 16 -33 ft (5-10 m) tall lava fountains at approximately 7:30 p.m. HST last night. There is no active lava within Moku'āweoweo caldera, and the Southwest Rift Zone is not erupting. All lava flows are on the northeast flank of Mauna Loa, and we do not expect any eruptive activity outside that area. No property is at risk currently. There is a visible gas plume from the erupting fissure fountains and lava flows, with the plume primarily being blown to the North. Via USGS
