Kilauea Summit Update – 5/14/15

After days of decreased tilt and lava inflation at the summit of Kilauea, two tiltmeters recorded an increase of tilt since Wednesday morning, according to Hawaiian Volcano Observatory scientists.

The increase was not at the lava lake, which remains steady about 65-80 feet beneath the floor of the original crater. HVO personnel say the tiltmeters showed an increase in the direction tangential to Halema’uma’u.

Seismicity continues to remain elevated below Kilauea’s summit.

For the week ending on May 12, sulfur dioxide emission rates averaged 3,400-6,900 tonnes/day at the summit.

Along the north flank of Puʻu ʻŌʻō, HVO reports that no significant tilt was recorded in the past day. In addition, no flows were noted within the Puʻu ʻŌʻō crater, based on thermal webcam imagery.

Emission rates of sulfur dioxide from all East Rift Zone vents were about 550 tonnes/day when last measured on May 11.

HVO continues to report active June 27 lava flows in an area northeast of Puʻu ʻŌʻō. These flow are approximately 5 miles from the vent, based on observations of webcam images.
