During 12-18 May HVO reported that activity at Kilauea continued from the summit and the east rift zone.
At the summit, occasional rising and falling of the circulating lava-pool surface continued at the deep pit inset within the floor of Halema'uma'u crater; glow from the vent was visible.
The plume of gas and ash from the summit vent drifted SW.
On 14 May the sulfur dioxide emission rate measured at the summit was1,000 tonnes/day.
The surface dimensions of the lava pool were an estimated 60 m by 90 m on 17 and 18 May.
At the east rift zone, lava flows that broke out of the TEB lava-tube system had advanced down the Pulama pali onto the coastal plain and headed S into the ocean.
Geologists confirmed a collapse of a 17 m by 75 m sliver of Pu'u 'O'o crater's N rim that occurred on 11 May.
