Kilauea (United States) - Report for 21 June-27 June 2017

During 21-27 June HVO reported that the lava lake continued to rise, fall, and spatter in Kilauea?s Overlook crater.
Webcams recorded incandescence from long-active sources within Pu'u 'O'o Crater, from a vent high on the NE flank of the cone, and from a small lava pond (which had many small spattering sites along the margin) in a pit on the W side of the crater.
The 61G lava flow, originating from a vent on Pu'u 'O'o Crater's E flank, continued to enter the ocean at Kamokuna.
Field observations on 31 May revealed that the lava delta had grown to an area of approximately 0.01 square kilometers.
A solidified lava ramp extended from the tube exit high on the sea cliff down to the delta, whose leading edge was about 100 m from the tube exit on the sea cliff.
Lava flows from the upper portion of the flow field continued to advance downslope, producing surface flows above the pali.
