Kilauea , Hawai . The lava lake at Kilauea’s summit remains active .

Activity Summary:
The lava lake at Kilauea’s summit remains active, as does the East Rift Zone lava flow northeast of Pu’u ‘O’o. The most distal active lava is about 8 km (5 mi) from Pu’u ‘O’o and does not currently pose a threat to nearby communities. Seismicity across the volcano is at background levels.

Summit Observations:
The summit began to deflate early in the day yesterday and continued to do so until early this morning, when inflation started. The level of Kilauea’s summit lava lake dropped slightly in response and was about 35 m (~115 ft) below the vent rim this morning, but will likely rise again as inflation progresses. Seismic activity across the volcano continues at background levels. Fluctuations in summit tremor amplitudes are related to spattering along the edges of the lava lake. The sulfur dioxide emission rate was about 5000 metric tons/day when last measured on March 19.

Pu’u ‘O’o Observations:
A small lava flow was erupted last night from a spatter cone on the northeast side of Pu’u ‘O’o’s crater floor. Inflation registered on the tiltmeter on the north flank of Pu’u ‘O’o is associated with rainfall. The sulfur dioxide emission rate from all East Rift Zone vents was about 240 metric tons/day when last measured on March 10.

June 27th Lava Flow Observations:
Observations yesterday found small breakouts spread over an area extending from 1.6 km (1.0 mi) to 7.6 km (4.7 mi) northeast of the vent on the flank of Pu’u ‘O’o. Active lava has been scattered within this same general area for the last several months and currently poses no threat to nearby communities.
