Slight fluctuations continue to occur at the summit of Kilauea, according to Hawaiian Volcano Observatory’s Monday morning report. The activity follow typical, and expected, Kilauea behavior.

Tilt at Kilauea’s summit switched to deflation on Sunday morning. In addition, the lava lake was measured to be about 130 feet from the Overlook crater’s new rim. HVO noted that lava within the lava lake has consistently declined since the Sunday measurement. Rock-cracking sounds were also heard coming from the Overlook crater.

A swarm of small earthquakes were felt in the upper east rift zone of Kilauea on Sunday. At Puʻu ʻŌʻō, seismicity rates remain at background levels.

According to HVO, when measured on June 19, the sulfur dioxide emission rate from all East Rift Zone vents was about 725 tonnes a day.

The June 27 lava flow continues to be monitored through webcam images. Breakouts in the area remain within 5 miles to the northeast of Puʻu ʻŌʻō.

June 19: Scattered breakouts were active at the margins of the June 27th flow, with only minor expansion of the flow margins over the past two weeks. This photo shows an active breakout on the south margin of the June 27th flow, moving over older ʻaʻā from Puʻu ʻŌʻō. USGS/HVO photo.

June 19:  Little has changed in Puʻu ʻŌʻō over the past month, and a small lava pond still exists within the circular pit in the western portion of the crater. This pit can be seen through the fume in this photo, and a tiny area of incandescence at the edge of the active pond is barely visible. USGS/HVO photo.

June 19: Scattered breakouts remain active northeast of Puʻu ʻŌʻō on the June 27th lava flow, but have not advanced significantly over the past month. This photo shows the farthest reach of active lava on the flow field today, which was about 8 km (5 miles) northeast of the vent on Puʻu ʻŌʻō. Minor brush fires were active where lava was entering forest. USGS/HVO photo.
