Kilauea activity update

The Hawaiian Volcano Observatory will remain operational during the lapse of federal government appropriations. Basic volcano monitoring will continue, as will forecasts and regular updates of volcanic activity. However, because of reduced staff, only critical sensors will be maintained; all other instrument network maintenance will cease, meaning that our monitoring capability will degrade over time. The HVO website,, will remain functional, but only those pages containing information about current volcano hazards will be maintained.

Because the majority of the HVO staff has been furloughed, the Volcano Watch articles will be suspended but we will continue to provide the weekly Kilauea update and the felt earthquake report.

A lava lake within the Halemaumau overlook vent produced nighttime glow that was visible via HVO’s Webcam during the past week. A deflation-inflation cycle occurred during the middle of last week, and the lava lake level fell and rose correspondingly.

On Kilauea’s east rift zone, two small breakouts from the Peace Day tube are active above the pali. The lower of these breakouts is barely visible from the visitor area in Kalapana. The Kahaualea 2 flow, fed from a spatter cone on the northeast edge of the Puu Oo crater, continues to burn forest north of Puu Oo. There are no active flows on the coastal plain, and there is no ocean entry.

One earthquake was reported felt on Hawaii Island in the past week. At 9 a.m. Monday, a magnitude 3.7 earthquake occurred 3 miles southeast of Kilauea summit at a depth of 2 miles.
