Kilauea, Hawaii, USA

HVO reported that during 5-11 November lava flowed SE through a tube system from underneath Kilauea’s Thanksgiving Eve Breakout (TEB) and rootless shield complex, reaching the Waikupanaha ocean entry. Thermal anomalies detected on satellite imagery indicated active surface flows. The sulfur dioxide emission rate at Pu’u ‘O’o was 2,000 tonnes per day on 7 November, near the 2005-2007 average background rate of 1,700 tonnes per day.

During the reporting period, Kilauea earthquakes were variously located beneath and to the S of the caldera and along the S-flank fault. Beneath Halema’uma’u crater earthquakes ranged from 40 to 60 (background is about 40), but were too small to be located more precisely. The vent in Halema’uma’u crater continued to produce a white plume that occasionally turned brown and drifted mainly SW. Night-time incandescence was intermittently seen at the base of the plume, and sounds resembling distant surf and rock clattering were heard in the vicinity of the crater. The sulfur dioxide emission rate was 900 tonnes per day on 7 November. The 2003-2007 rate average was 140 tonnes per day.
