Volcano Watch for October 10, 2013

Release Date:

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 have been suspended. We will continue to provide the weekly Kīlauea update and the felt earthquake report to the local newspapers. Hawai‘i County Civil Defense is now the point-of-contact for any Great Hawaii Shakeout (coming up on October 17, 2013) questions (www.shakeout.org/hawaii).

Volcano Activity Update

A lava lake within the Halema‘uma‘u Overlook vent produced nighttime glow that was visible via HVO's Webcam during the past week. A deflation-inflation cycle (DI event) started on October 8 and inflation is continuing as of this writing (Thursday, October 10). The lava lake level fluctuated correspondingly.

On Kīlauea's East Rift Zone, one small breakout from the Peace Day tube remains active above the pali, based on glow visible from Kalapana. The Kahauale‘a 2 flow, fed from a spatter cone on the northeast edge of the Pu‘u ‘Ō‘ō crater, continues to slowly advance across old flows and into the forest northeast of Pu‘u ‘Ō‘ō.

One earthquake was reported felt on the Island of Hawai‘i in the past week. On October 5, 2013, at 8:57 p.m., HST, a magnitude-3.6 earthquake occurred 5 km (3 mi) southwest of Kalapana at a depth of 7 km (4 mi).
