Mauna Loa 2022 eruption anniversary video. Mauna Loa is Earth's largest active volcano and covers just over half of the Island of Hawaiʻi. It erupted most recently in November-December 2022, and it will erupt again.

Aerial view of fissure 3 erupting on the Northeast Rift Zone of Mauna Loa on December 9, 2022. The eruption continues but the vigor has greatly reduced over the past 24 hours. USGS video by M. Patrick. 

Aerial view of the upper lava channel from fissure 3 on the Northeast Rift Zone of Mauna Loa. On December 9, 2022, Hawaiian Volcano Observatory geologists noted a reduced output of lava at fissure 3 and this photo shows that the level of lava in the channel is the lowest it has been since the eruption started. USGS video by M. Patrick. 

During a morning overflight on December 9, 2022, Hawaiian Volcano Observatory geologists noted a reduced output of lava at fissure 3 on the Northeast Rift Zone of Mauna Loa. The lava fountain is much lower than yesterday and the lava in the channel is much lower than the levees. USGS video by M. Patrick. 

The Northeast Rift Zone eruption of Mauna Loa continues with a major change overnight. The fissure 3 (F3) vent continues to erupt but the supply of lava appears to be much reduced this morning. Lava is overtopping channels near the vent with flows extending no farther than 2.5 mi (4 km) from the vent.

Video of the fissure 3 lava channel near the vent, high on the Northeast Rift Zone of Mauna Loa. Near the vent, the lava flow velocity has been measured at 32-39 feet per second (10-12 meters per second) within the lava channel. USGS video by M. Patrick. 

An overflight the morning of December 7, 2022, provided this aerial view of fissure 3 erupting at an elevation of 10,500 feet (meters) above sea level on the Northeast Rift Zone of Mauna Loa. The fissure is feeding a lava channel; near the vent, the lava flow speed has been measured at 32-39 feet per second (10-12 meters per second). USGS video by M.

A lava boat traverses down the fissure 3 lava channel during the Northeast Rift Zone eruption of Mauna Loa on December 7, 2022. Lava boats or lava balls form when portions of the fissure cone or lava channel levees break away and are rafted down the lava stream.

A close up view of the fissure 3 lava channel erupting from Mauna Loa's Northeast Rift Zone, as seen by Hawaiian Volcano Observatory field crews on the morning of December 5, 2022. The large bumps are standing waves in the lava.

View of fissure 3 erupting on the Northeast Rift Zone of Mauna Loa the morning of December 4, 2022. Lava fountaining at the vent was approximately 100 feet (33 m) tall yesterday; fragments of lava are deposited in the area near the vent construct the cone visible in this video. USGS video by F. Trusdell.
