Aerial view of the front of a lava flow from fissure 3 on Mauna Loa's Northeast Rift Zone. Hawaiian Volcano Observatory geologists noted that the supply of lava was reduced the morning of Thursday. Lava was overtopping channels near the vent with flows extending no farther than 2.75 mi (4.4 km) from the vent the morning of Thursday (one of which is pictured here).

Lava boats are visible in the upper parts of the fissure 3 lava channel during the Northeast Rift Zone eruption of Mauna Loa on Thursday. 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. As they move along in the channel, additional lava can cool to their surface to form accretionary lava balls.
