Kilauea Summit Update – 6/1/15

Kilauea’s summit is back to recording deflationary tilt after inflating briefly last week.

Hawaiian Volcano Observatory said Monday morning that tiltmeters at the summit of Kilauea began to show a deflationary tilt at approximately 4:30 p.m. Friday and continued into the weekend. HVO reports that the rate of deflation has slowed but tiltmeters continue to record the deflationary tilt.

Seismic tremor has persisted and episodic bursts that are associated with spattering continue to occur within the Overlook vent. When measured on May 31, the lava lake level within the Overlook crater measured about 73 meters below the original floor of Halema’uma’u, a decrease of 29 meters from the day prior when the level was measured at 44 meters below Halema’uma’u.

Seismicity below Kilauea’s summit remains at background levels.

At Puʻu ʻŌʻō, tiltmeters on the north flank have recorded no significant tilt and seismicity rates are at background levels over the past day.

June 27 lava flow surface activity continues to be observed by HVO scientists through webcam and satellite imagery. The activity remains within 4.3 miles to the northeast of Puʻu ʻŌʻō.
