The summit of Kilauea underwent deflationary tilt on Sunday, a trend that continued into Monday. As a result of the deflation, Hawaiian Volcano Observatory reports that the lava lake within the Overlook crater has also dropped slightly.
According to HVO, fluctuations within the lava lake were also seen as spattering occurred.
Seismic levels remain at low background levels, with small earthquakes below Kilauea summit, along the Southwest Rift Zone, and across the south flank of Kilauea.
Puʻu ʻŌʻō has seen no change in recent weeks. HVO noted Monday that the incandescent, outgassing vents within Puʻu ʻŌʻō remain. Seismicity also continues at low background levels.
Webcam observation by HVO geologists of the June 27, 2014 lava flow continue to show activity on the flow field. Breakouts have been observed in an area about 2.5 to 5 miles to the northeast of Puʻu ʻŌʻō.

July 23: Breakouts have further buried Puʻu Kahaualeʻa in recent weeks. The cone was originally covered in thick vegetation, but on July 23 only a single dead tree stood on the remnants of the cone rim. USGS/HVO photo.

July 23: Pele’s hair covers the roadside along Crater Rim Drive, next to the Halemaʻumaʻu parking lot, in an area of Hawaiʻi Volcanoes National Park closed, July 23, to the public due to proximity to the summit lava lake. The Pele’s hair (long strand of volcanic glass) is emitted from the lava lake and carried upwards by the rising gas plume, and then drifts downwind. USGS/HVO photo.
