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. Summit tiltmeters began recording deflationary tilt after midnight; earthquake rates and seismic tremor have not changed significantly in the past day.
Summit tiltmeters began to record deflationary tilt this morning around 2:30 am. The summit lava lake level when measured Friday morning was 39 m (128 ft) below the current Halema’uma’u crater floor. Based on web camera imagery, the lake level appeared to have risen a few meters yesterday before the tilt turnaround. The level has decreased since that time and is similar to that of yesterday morning. Seismic activity 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 average sulfur dioxide emission rates during the past week ranged between 1,200 and 4,300 metric tons/day.
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 has recorded steady inflationary tilt for the past several days. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when last measured on April 20.
June 27th Lava Flow Observations:
During periods of clear weather, webcam images continue to show small breakouts scattered northeast of Pu’u ‘O’o, where they have been occurring for the past several months. This pattern is consistent with field observations on April 12 when the most distant breakouts were about 5.7 km (3.5 mi) northeast of Pu’u ‘O’o .
