Reports on Kilauea eruption

Kilauea Daily Update issued Jun 9, 2007 06:33 HST Volcanic-Alert Level WATCH - Aviation Color Code ORANGE

Report prepared by the Hawaiian Volcano Observatory:Summary: Kilauea volcano continues to erupt from the Pu`u `O`o vent on the East Rift Zone. The eruption is stable - the Poupou ocean entry continues to build a delta. A more-than-the-typical number of small shallow earthquakes have been occurring in the upper rift zones since May 12, 2007.The long story that won't change daily: Over the past several months, Kilauea caldera has been expanding at a rate of 1.5 cm/month indicating minimal magma storage there; most of the magma supply continues to feed the Pu`u `O`o vent. Pu`u `O`o cone is slowly collapsing as shown by cracks spreading on its south flank and about 1 cm/month subsidence of its north flank.

The PKK lava tube, the primary tube from Pu`u `O`o, is active but only to feed the Campout and the Petunia tubes within about 1 km from the vent. The Campout tube provides lava to the coast toward the base of Royal Gardens subdivision and into the ocean on May 16 at Poupou. The Petunia flow has advanced about 2 km and is not yet visible below the pali. While we can't see it except on helicopter overflights, twice daily satellite imagery confirms that the Petunia flow is still somewhat active. The Kamokuna and East Lae`apuki ocean entries are no longer active. Lava continues to enter the ocean only at the Poupou location within the Hawai`i Volcanoes National Park.

The last 24 hours at Kilauea summit: Small shallow earthquakes were recorded south and west of Halema`uma`u crater. The tiltmeter network recorded slow inflation across the summit. Seismic tremor remains at low levels. Air quality was good.Last 24 hours at Pu`u `O`o: No big changes. Incandescence could be seen reflected in the gas plumes at East Pond, January, South Wall Complex, and Drainhole vents. Incandescence from Beehive vent was visible for the first time in months. The POC tiltmeter recorded the usual oscillations. Seismic tremor remains at moderate levels.NPS eruption crew report from the coast for Friday afternoon: Numerous breakouts continue inland of the Poupou entry on the east side of the flow field. A strong steam plume is visible from the Poupou entry.

Seismic tremor remains at moderate levels.

The surface activity is concentrated 500-1600 m inland. The branch of the Campout flow that feeds the Poupou entry feeds an arm to the east just outside the National Park boundary and another to the western side of the Ka`ili`ili branch.

A surface flow is advancing just outside the eastern park boundary and is about one-quarter mile inland of the coast.

Poupou entry consists of three entries and is producing a strong steam plume visible during the day. On the eastern side of the flow field, incandescence in steam and lava streams are visible from pullouts along the coast road.

Lava continues to enter the ocean at the Poupou location within the Hawai`i Volcanoes National Park. The last 24 hours at Kilauea summit: There was again a more-than-typical number of earthquakes recorded and most were located in the uppermost parts of the southwest and east rift zones. The tiltmeter network recorded no significant summit-wide changes.

Seismic tremor remains at low levels except for two small bursts of tremor at 4 pm and 2:50 am. Air quality was poor between 3 and 6:30 pm, but good at all other times.Last 24 hours at Pu`u `O`o: No big changes. Incandescence could be seen reflected in the gas plumes at East Pond, January, South Wall Complex, and Drainhole vents. HVO scientists reported that lava in the East Pond vent was about 21 meters below the rim. The POC tiltmeter recorded the usual oscillations. Seismic tremor remains at moderate levels.HVO scientists yesterday reported an advancing flow from the vicinity of Pu`u `O`o paralleling the Campout tube.

The Campout tube system is still supporting lots of surface flow activity on the eastern side of the coastal plain between the base of Royal Gardens subdivision and the coast. Video of this activity may be shown on TV news. Poupou is wide with two main entry points. HVO scientists also found sluggish surface flow activity about 2-2.5 km inland of the inactive East Lae`apuki entry, probably from the western branch of the Campout flow that we thought might be inactive.NPS eruption crew report from the coast for Friday evening: No activity is visible on the pali. Surface flow activity has shifted to the east side of the flow field between Royal Gardens subdivision and the Poupou entry. Lots of surface flow activity is reported on the eastern park boundary.

Poupou entry is producing a strong steam plume visible during the day. On the eastern side of the flow field, incandescence in steam and lava streams are visible from pullouts along the coast road.
