Hawaiian Volcano Observatory reports that on Sunday night at about 9:30 p.m., the first deflationary-inflationary event in recent weeks at the summit of Kilauea began.

Tiltmeters at Kilauea’s summit have recorded about 1 microradian of deflationary tilt, as of HVO’s Monday morning report.

Lava within the Overlook crater lava lake continues to circulate and spatter, as observed by HVO officials in webcam images. HVO reports that the surface of the lake dropped as deflationary tilt began.

Seismic levels remain low, but persist with volcanic tremor and variations in tremor strength. HVO also reports that a small number of discrete events also add to the seismic activity.

Tiltmeters at Puʻu ʻŌʻō have not shown any signs of change in tilt as the DI event at the summit of Kilauea is underway. Incandescent outgassing vents continue to be viewed through webcam images. Puʻu ʻŌʻō seismic activity is at background levels.


Observations of the June 27, 2014 lava flow show that the flow has expanded since July 6. According to HVO, observations of data from remote sensing sources show that the flow is believed to have expanded at its western-most lobe that is pointing to the north. The lava breakouts are still believed to be within 5 miles of Puʻu ʻŌʻō.
