Kilauea Summit Update – 5/26/15

After a long weekend of steady activity, Hawaiian Volcano Observatory noted Tuesday morning continued deflationary tilt and normal seismic levels at Kilauea’s summit.

HVO reports that the tiltmeter network at the summit has recorded consistent levels of minor deflationary tilt since May 24. All of the stations began to record the activity at about 6 p.m. on Sunday.

Seismic rates continue to remain at normal, background levels below Kilauea’s summit, the upper East Rift Zone, and the Southwest Rift Zone.

For the week ending May 22, HVO says sulfur dioxide emission rates range between 3,800 and 8,500 tonnes a day.

No significant tilt continues to be seen, according to a tiltmeter located on the north flank of Puʻu ʻŌʻō. Seismic rates at Puʻu ʻŌʻō have also remained normal.

When last measured on May 19, the combined sulfur dioxide emission rate for all East Rift Zone vents was 360 tonnes a day.

Scientists with HVO continue to monitor the June 27 lava flow through webcam and satellite imagery. The images show surface flow activity that have originated from breakouts northeast of Puʻu ʻŌʻō. These flows are all within 5.3 miles of Puʻu ʻŌʻō.
