Aerial view of fissure 3 eruption lava channel on the Northeast Rift Zone of Mauna Loa the morning of December 4, 2022. Fissure 3 has produced several lava channels that are winding their way down the northeast slope of Mauna Loa, coalescing into a single flow front.  As of 7 a.m. today, December 4, the flow front was about 2.3 mi (3.6 km) from the Daniel K. Inouye Highway (Saddle Road). USGS image by L. DeSmither.

Hawaiian Volcano Observatory Scientists are monitoring the eruption of fissure 3 on the Northeast Rift Zone of Mauna Loa. In the field, scientists relay geospatial information on the lava flow front location, document fissure 3 lava fountain and lava channel dynamics, and deploy new instrumentation to help monitor the eruption remotely.
