Kilauea , Hawai :

Activity Summary:
Eruptions continue at Kilauea Volcano’s summit and East Rift Zone. The lava flow to the southeast of Pu’u’O’o continues to spread and advance, still posing no threat to nearby communities. The lava lake at Halema’uma’u Crater continues to circulate and spatter, and the lake level has risen slightly over the past day. Low rates of seismicity are observed across the volcano, and long-term deformation trends show continued inflation beneath the summit and uppermost Southwest Rift Zone. The June 27th lava flow northeast of Pu’u’O’o is no longer active.

Summit Observations:
Gentle inflationary tilt continues. The summit lava lake at Halema’uma’u continues to circulate and spatter. This morning, measurements show the lake surface is 29 m (~95 ft) below the adjacent crater floor. Low rates of seismicity in the summit caldera region are noted, with minor fluctuations in seismic tremor related to variations in lava lake circulation and spattering. Sulfur dioxide emissions from the summit vent over the past week ranged from 3,500 to 7,300 metric tons/day.

Pu’u’O’o Observations:
HVO webcams show several incandescent vents on the floor of Pu’u’O’o crater, as usual. Tilt measurements over the past day have been affected by rainfall. There are no significant changes in seismic activity at Pu’u’O’o. Sulfur dioxide emission rate from all East Rift Zone vents when last measured on June 22 was about 350 metric tons/day.

Lava Flow Observations:
The active lava flow southeast of Pu’u’O’o continues to advance and spread. An HVO overflight yesterday revealed the flow is 5.1 km (3.2 miles) long, and the flow front was about 100 m (330 ft) from the northern boundary of the abandoned Royal Gardens subdivision. Over the past week the flow front has advanced at a rate of roughly 100 m per day (330 ft per day). Bright incandescence is visible in the overnight webcam views of the active lava flow field, marking lava tube skylights and scattered breakouts near the flow front.
