Aerial view of the lowermost section of the active fissure system during an overflight early this morning. The view is looking toward the south; note ocean at top of photo. Fissure 17 is the on the left-hand side of photo; fissure 18 is in the middle; and fissure 20 are the two low fountaining areas in the middle right of photo.

This morning, the line of fountains on fissure 17 coalesced into a large fountain that was sending lava 50 meters (164 feet) into the air, with small bits of spatter thrown up to 100 meters (328 feet) high. At about 12:00 p.m. HST, HVO geologists flying over the area reported that fissure 17 was going strong
