Based on visual observations from HVO crews and web camera views, HVO reported that during 4-10 June lava flowed SE through a lava tube system underneath Kilauea’s Thanksgiving Eve Breakout (TEB) and rootless shield complex to the Waikupanaha ocean entry. Incandescence was occasionally noted from the TEB vent area. Gas continued to jet from a vent about 30 m below Pu’u ‘O’o crater’s E rim. The sulfur dioxide emission rate was generally high and fluctuated between 1,530 and 3,080 tonnes per day when measured on 3, 5, 6, and 9 June. The background rate was about 2,000 tonnes per day when measured on 25 May and earlier.
During the reporting period, Kilauea summit earthquakes were located beneath the summit, along the S-flank fault, and along SW rift zones. An average of 10-20 small earthquakes (not located) were detected daily. The eruption from the vent in Halema’uma’u Crater continued to produce white plumes with minor ash content that drifted mainly SW. During the night incandescence was seen at the base of the plume. Seismic tremor was elevated. The sulfur dioxide emission rate was high and fluctuated between 680 and 1,160 tonnes per day when measured during 3-9 June. The background rate was 150-200 tonnes per day.
