Aerial image of the lava channel issuing from fissure 3, erupting high on the Northeast Rift Zone of Mauna Loa. The reduced lava output at fissure 3 is evident in the low level of lava in the channel. Mauna Kea is visible in the background of the image. USGS image by P. Dotray.

Eruptive activity in Mauna Loa's Northeast Rift Zone fissure 3 was diminished on the morning of December 9, 2022, around 8:20 a.m. HST. This view from a monitoring overflight shows little fountaining activity in the fissure and ponded lava flowing out of the fissure to the east. USGS photo by K. Lynn.

Eruptive activity in Mauna Loa's Northeast Rift Zone fissure 3 was dominated by ponded lava inside the fissure that drained to the east into the lava channel system, as viewed here from a monitoring overflight around 10:30 a.m. HST on December 9, 2022. USGS photo by K. Lynn.

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 image 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.

The Northeast Rift Zone eruption of Mauna Loa that began the evening of November 27, 2022, continues as of December 9, 2022 (twelfth full day). One active fissure, fissure 3, feeds lava flows downslope to the north.

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.

Aerial image of fissure 3 erupting on the Northeast Rift Zone of Mauna Loa on December 8, 2022. The eruption has built up a cone around the vent, which was 98 feet (30 meters) tall on December 7, 2022. USGS image by T. Orr.

Aerial image of fissure 3 erupting on the Northeast Rift Zone of Mauna Loa on December 8, 2022. Lava fountain heights were very variable on December 8; the fountains were jet like, sometimes spraying at an angle just off vertical and with pulses of activity. USGS image by T. Orr.

Lava boats are visible in the upper parts of the fissure 3 lava channel during the Northeast Rift Zone eruption of Mauna Loa on December 8, 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 helicopter overflight on December 7, 2022, allowed for aerial visual and thermal imagery to be collected of the Northeast Rift Zone eruption of Mauna Loa. This map only shows activity from Fissure 3 on the Northeast Rift Zone, which is feeding a lava flow to the north.
