Kilauea , Hawai : Kilauea’s summit lava lake level continued to drop.

Activity Summary:
Kilauea continues to erupt at both the summit, where there is a circulating lava lake, and from its East Rift Zone, where surface lava flows are active northeast of the Pu’u ‘O’o vent. The East Rift Zone lava flow currently poses no threat to nearby communities. The summit deflationary trend that started on April 4th continued during the past day; earthquake rates and seismic tremor have not changed significantly in the past 24 hours.

Summit Observations:
Summit tiltmeters continued to record deflationary tilt during the past 24 hours and Kilauea’s summit lava lake level continued to drop. Yesterday morning the lake level was 52 m (170 ft) below the crater floor and this morning was measured about 58 m (190 ft) below the floor. This latest deflationary period has interrupted the longer-term inflationary trend of the summit, similar to previous deflation events. Seismic activity across the volcano has not changed significantly during the past day. Fluctuations in summit tremor amplitudes are related to spattering along the edges of the lava lake. The sulfur dioxide emission rate was about 1800 metric tons/day when last measured on April 3.

Pu’u ‘O’o Observations:
There were no observable changes at Pu’u ‘O’o during the past day. Outgassing continues from the spatter cones on the crater floor. A tiltmeter on the north flank of Pu’u ‘O’o continued to show deflationary tilt during the past 24 hours. Over a longer time period, GPS instruments that span Pu’u ‘O’o show the cone is spreading, which suggests the magma system beneath the vent is pressurizing; this current spreading trend began late in 2015. 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:
The webcam shows small breakouts scattered northeast of Pu’u ‘O’o, where they have been occurring for the past several months. A satellite image from April 3 showed the most distal of these breakouts was 7.6 km (4.7 mi) northeast of Pu’u ‘O’o.
