At Kilauea, an early morning flight on August 7 shows weak activity on fissure 8; weak lava bubbling and convection was occurring in the pond, which was around 5-10 m (about 16-33 ft) below the channel spillway.
A weak plume of gas overcomes it, and the upper lava channel is drained.
The number of active exudates on the coast has decreased; the activity near the Pohoiki boat ramp has not progressed significantly towards it.
Fractures parallel to the coastline develop in the lava delta near Kapoho; this kind of delta is unstable by nature and likely to collapse.
The top deformation measured by a tilt meter and GPS instruments has practically stopped.
