Kilauea, Hawaii, USA

HVO reported that during 13-19 August, lava flowed SE through a lava tube system from underneath Kilauea’s Thanksgiving Eve Breakout (TEB) and rootless shield complex to the Waikupanaha ocean entry. Incandescence was noted from the rootless shield complex during 13-15 August. Earthquakes were in various locations along the Koa’e fault system, S and W of the caldera, beneath the summit, along the S-flank faults, and along the E and SW rift zones. Beneath Halema’uma’u crater, around 40 small earthquakes per day (background is 20-40) also occurred but were too small to be located more precisely. The vent in Halema’uma’u crater continued to produce a predominantly white plume with minor ash content that drifted mainly SW. The plume was occasionally tinged brown. Night-time incandescence was intermintently seen at the base of the plume, and rock impacts and rushing sounds were heard in the vicinity of the crater.
