Kilauea Summit Update – 7/9/15

Inflationary tilt that began at the summit of Kilauea on July 6 has leveled off, according to Hawaiian Volcano Observatory.

The trend netted just under a microradian of inflationary tilt during its three day course, officials say.

Circulation within the Overlook Crater’s lava lake, in addition to spatte,r continued to be noted by HVO. The level of the lake has dropped in the past day and is currently about 148 feet below the rim of the Overlook vent.

Seismicity rates beneath the summit of Kilauea are at very low levels. HVO first noted Wednesday that the majority of the seismic activity is due to persistent volcanic tremor and variation in tremor strength, not any one particular event.

As of July 7, sulfur dioxide emission rates ranges from 2,000-3,300 tonnes per day for July 4-5,  then increase to 9,100 tonnes per day, according to HVO.

At Puʻu ʻŌʻō, no significant changes have been seen. Webcam images continue to show multiple incandescent outgassing vents within the crater. These were first observed on June 30. Seismic activity in the area remains at low background levels.

Observation of the June 27, 2014 lava flow show continued active breakouts in an area within about 5 miles to the northeast of Puʻu ʻŌʻō.
