“…..Since eruptions in the Leilani Estates neighborhood began on May 3, the flows of lava have destroyed 36 structures as of Friday — at least 26 of them homes — and covered 117 acres.…..”

HAWAIIAN VOLCANO OBSERVATORY STATUS REPORT

KILAUEA VOLCANO (VNUM #332010)
19°25’16” N 155°17’13” W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE

Lower East Rift Zone Eruption
Volcanic unrest in the lower East Rift Zone of Kīlauea Volcano continues. While no lava has been emitted from any of the 15 fissure vents since May 9, earthquake activity, ground deformation, and continuing high emission rates of sulphur dioxide indicate additional outbreaks of lava are likely. The location of future outbreaks is not known with certainty, but could include areas both uprift (southwest) and downrift (northeast) of the existing fissures, or resumption of activity at existing fissures. Communities downslope of these fissures could be at risk from lava inundation.

Residents in lower Puna should remain informed and heed Hawaii County Civil Defense closures, warnings, and messages (http://www.hawaiicounty.gov/active-alerts).

Kīlauea Volcano Summit
Tiltmeters at the summit of Kīlauea Volcano continue to record deflationary tilt. Based on this and field observations of the past two days, the lava lake level continues to drop. Rockfalls from the steep crater walls have generated small ash clouds mixed with white condensed water vapor intermittently throughout the day. These ash clouds have been relatively low concentration and have risen only a few thousand feet above the ground generating very localized ashfall. More explosive activity generating larger ash clouds remains possible.

Earthquake activity in the summit remains elevated. Many of these earthquakes are related to the ongoing subsidence of the summit area and earthquakes beneath the south flank of the volcano.
