Pu‘u ‘O‘o lava flow less than two miles from ocean

Kilauea Volcano Activy Update for Saturday, July 2, 2016 by the USGS/Hawaiian Volcano Observatory

Activity Summary: Eruptions continue at Kīlauea Volcano’s summit and East Rift Zone. The lava flow to the southeast of Puʻu ʻŌʻō continues to be active and does not pose a threat to nearby communities. The lava lake at Halemaʻumaʻu Crater continues to circulate and spatter, and the lake level rose several meters (yards) during the past 24 hours. Low rates of seismicity are observed across the volcano.

Summit Observations: Tiltmeters at the summit continued to record an inflationary trend during the past 24 hours, and the level of the summit lava lake at Halemaʻumaʻu rose by several meters (yards). This morning the lava level is about 30 m (98 ft) below the Halemaʻumaʻu Crater floor based on thermal webcam images. 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 6,200 metric tons/day.

Puʻu ʻŌʻō Observations: HVO webcams show several incandescent vents on the floor of Puʻu ʻŌʻō crater, as usual. There are no significant changes in seismic activity at Puʻu ʻŌʻō. A tiltmeter on the north flank of Puʻu ʻŌʻō has recorded very little change during the past few days. Sulfur dioxide emission rate from all East Rift Zone vents when last measured on June 27 was about 320 metric tons/day.

Lava Flow Observations: The active lava flow southeast of Puʻu ʻŌʻō continued to be active during the past 24 hours. On Thursday afternoon, geologists reported the flow front was about 150 m beyond the base of the pali along the western boundary of the abandoned Royal Gardens subdivision; the flow was about 7.6 km (4.7 miles) long as measured along the axis of the tube. Bright incandescence is visible in the overnight webcam views of the active lava flow field, marking lava tube skylights and activity on the pali.
