Kīlauea Volcano’s lower East Rift Zone

The Unmanned Aircraft Systems (UAS) team assessed conditions at the fissure 8 cone and upper lava channel on August 17, 2018. At the time of the flight, the lava pond within the cone had crusted over with no observed incandescence. The reddish-brown rock inside the cone is the result of oxidation; the interaction of heated rock and gases causes black basaltic cinders to change color, similar to rust forming on metal.

This morning, USGS scientists flying over fissure 8 noticed a change in the vent from yesterday. Gas jets were throwing spatter—fragments of glassy lava (light gray deposits)—from small incandescent areas deep within the cone. This activity is an indication that the lower East Rift Zone eruption may be paused rather than pau (over).
