|26 Oct 2014 update from HVO
Activity Summary: Kīlauea continued to erupt at its summit and within the East Rift Zone, and gas emissions remained elevated. Currently, the June 27th flow has traversed the Pāhoa cemetery between Apa`a St/Cemetery Rd and Pāhoa Village Road and is continuing downslope. The leading edge of the flow has been advancing at rates varying between 9 and 15 m/hr (10 to 16 yd/hr) during the past 24 hours. The flow front has spread out since yesterday afternoon and is roughly estimated to be about 150 yd wide at 9AM this morning. It is currently about 760 m (0.5 mi) straight-line distance from Pāhoa Village Road and 1.4 km (0.9 mi) from Hwy 130.
June 27th Lava Flow Observations: HVO scientists monitored the leading portions of the June 27th flow on the ground yesterday. The narrow lobe that had been moving rapidly downslope reached Apaʻa St/Cemetery Rd near the driveway to the Pāhoa cemetery at 03:20 yesterday morning and finished crossing it at 03:50.
As of yesterday afternoon, this flow is the only area of the flow front that is advancing downslope. The rate of advance was varying between 10 and 15 m/hr (11-16 yd/hr) yesterday. The front moved 140 m (150 yd) from 5pm yesterday to 9am this morning, a rate of 9 m/hr. There appears to be an area of slightly steeper slope just below the cemetery and higher advance rates are possible if the flow reaches that point. The flow front was about 40 m (45 yd) wide at 5pm Saturday, but spread out in the relatively flat terrain near the cemetery and is roughly estimated to be (150 yd) wide presently.
The flow was deflected away from the steepest-descent line it had been generally following, and toward the cemetery, by an old man-made cane-field berm just above Apaʻa Street. The flow is now advancing downslope between two intersecting steepest-descent paths and will likely return to the original steepest-descent path about 300 m (330 yd) upslope from Pāhoa Village Rd (see map ).
Scientists are currently monitoring the flow front
3 Jan 2013 update from HVO
This is an excerpt of a report on the status of Kilauea volcanic activity (available at http://hvo.wr.usgs.gov/activity/kilaueastatus.php).
Eruption returns to Puu Oo crater after earlier floor collapse and new fissure eruption at Napau Crater (March 2011)
HVO reported that at 10:09 a.m. HST March 26, 2011, lava returned to the Puu Oo crater after a 17-day hiatus in activity there. The return was accompanied by a brief burst of seismic tremor and a short (1 hr long) sequence of deflation followed by inflation.
6 March 2011: The floor of Puu Oo crater collapsed spectacularly in the past few days and a new fissure eruption opened up in Napau Crater. This sequence of activity is reminiscent of 1997, when the Puu Oo cone became temporarily inactive and a fissure eruption opened up 2 km away, at Napau. The reduced and cropped images at left are from HVO website
The sequence of events are described here, condensced from the the HVO press release:
Wall collapse at Lava lake at Kilauea Summit (Halemaumau) (March 2011)
things have been heating up again at Halemaumau with a roiling lava lake in the active pit. Check out the action from the HVO web cam
explosive eruption rocks Halemaumau in 2008
HVO reported that a small explosion occurred at the Kilauea summit in the very early hours of March 19, 2008, making this the first explosion there since 1924. Lava was not erupted during the gas explosion, but lithic blocks were scattered over a 75 acre region in an often visited part of Hawai'i Volcanoes National Park. A 20-30 m wide crater was formed in the explosion, in the same area where intense sulfur dioxide gas venting has been occuring lately, with incandescent (hot) rocks has been occuring over the past week or so. The largest piece of material ejected in the explosion is believed to measure about a cubic meter. The HVO webvsite has additional information, photos, and a newly installed Halemaumau webcam for your reading and viewing pleasure.
