Surface breakouts remained active on the pali and coastal plain, but the leading tip of the flow has advanced little since mapping on Sunday. This morning, the flow front was about 940 m (0.6 miles) from the ocean. Activity upslope of the flow front was widening the flow margins.

Above the pali there are no surface breakouts, and lava is carried downslope within the subsurface lava tube system. The trace of the lava tubes is evident by the line of fuming point sources along the flow. Puʻu ʻŌʻō, and the vent for the current flow, are in the upper left portion of the photo.

Kilauea Volcano Status

Activity Summary: Eruptions continue at Kīlauea Volcano’s summit and East Rift Zone. The 61G lava flow extending southeast of Puʻu ʻŌʻō continues to be active on the coastal plain. The flow does not pose a threat to nearby communities. The lava lake at Halemaʻumaʻu Crater continues to circulate and spatter. Minor inflationary tilt has been recorded at the volcano summit over the past day. There has been no significant change in seismicity across the volcano.

Summit Observations: Tiltmeters at the summit of Kilauea recorded minor inflationary tilt over the past day. This morning, the lava lake at Halemaʻumaʻu was 29.5 meters (97 feet) below the floor of Halema`uma`u. Minor fluctuations in seismic tremor related to variations in lava lake circulation and spattering continue. Sulfur dioxide emissions from the summit vent over the past week ranged from 3,900 to 7,300 metric tons/day.

Puʻu ʻŌʻō Observations: During an overflight yesterday, HVO geologists noted no significant changes at Puʻu ʻŌʻō. HVO webcams show several incandescent vents on the floor of Puʻu ʻŌʻō crater, as usual. There were no significant changes in seismic activity. A tiltmeter on the north flank of Puʻu ʻŌʻō has shown little change in the past 24 hours. The sulfur dioxide emission rate from all East Rift Zone vents when last measured on July 12 was about 320 metric tons/day.

Lava Flow Observations: The 61G lava flow, southeast of PuÊ»u ʻŌʻō continues to be active on the coastal plain on KÄ«lauea’s south flank. HVO geologists visited the flow field yesterday and at midday, the flow front was about 940 m (0.6 miles) from the ocean. The actual flow tip had stalled but many breakouts were active upslope overplating and widening the flow field. Bright incandescence is visible in the overnight webcam views of the active lava flow field, marking lava tube skylights above the pali.
