An aerial image of Fissure No. 3 erupting on Mauna Loa's Northeast Rift Zone the morning of Dec. 10. The lava output has greatly decreased over the past two days and within the fissure cone. Geologists noted a small lava pond has replaced the lava fountain.K. MULLIKEN/USGS
Just days ago, lava was full in the channels from the Fissure No. 3 eruption on Mauna Loa's Northeast Rift Zone. Over the past two days, the lava output has greatly reduced. The channels appear drained of lava and no longer feeding the main flow front.K. MULLIKEN/USGS

Eruption activity at Mauna Loa's Northeast Rift Zone Fissure No. 3 was dominated by ponded lava inside the fissure that drained to the east into the lava channel system. This photo was taken around 10:30 a.m., Dec. 9.M. PATRICK/USGS

An aerial image of the lava channel from Fissure No. 3 at the Northeast Rift Zone of Mauna Loa. The reduced lava output is visible in the low level of lava within the channel. Mauna Kea is visible in the background of the image.
