Detailed Description

Aerial view of Fissure 3 erupting on the Northeast Rift Zone of Mauna Loa, and the channel that exits it to the left side of the photo. Over the past 24 hours, Fissure 3 has built up a significant spatter rampart around its lava fountains. The air is thick with a sulfur plume that is degassing from the lava as it rises to the surface here. USGS image by D. Downs.
