Kilauea Summit Update – 6/9/15

Slight inflation has once again been observed at the summit of Kilauea, in what has been studied as a back-and-forth of activity. Hawaiian Volcano Observatory reported that after recording a deflationary trend since last Friday, Kilauea’s summit began to record inflationary tilt early Tuesday morning.

HVO also reported that episodic bursts of seismic tremor continue at the summit. These bursts are associated with periods of vigorous spattering within the Overlook vent. Tuesday morning, the lava lake within the Overlook crater was measured to be about 203 feet below the current floor of Halema’uma’u. The lake has risen by about 37 feet since Sunday afternoon, according to calculations based on HVO’s reports.

Seismic activity both below the summit of Kilauea and at Puʻu ʻŌʻō have continued to remain at background levels.

Along the north flank of Puʻu ʻŌʻō, tiltmeters have shown no significant tilt, a continuation of activity seen in recent weeks in the area.

HVO continues to monitor the June 27 lava flow through webcam and satellite imagery. According to those observations, active lava breakouts remain within 5 miles to the northeast of Puʻu ʻŌʻō.
