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
Scientists of the USGS Hawaiian Volcano Observatory conducted ground observations of the June 27th lava flow on Thursday, October 30, 2014. As of 5 PM, HST, the leading edge of the flow had stalled approximately 155 meters (170 yards) in a straight line distance from Pāhoa Village Road. The flow advanced only about 30 meters (33 yards) over the past 24 hours. The leading edge is inflated with a few small oozing breakouts just behind the flow front, however, so it is possible that the flow may advance again without warning.
A new outbreak of lava occurred from the northern margin of the lava flow in a forested area about 100 meters (110 yards) downslope (northeast) of the Pāhoa cemetery. This flow was moving downslope along the north margin of the existing flow as of 5 PM. This breakout is now the major locus of activity on the lower part of the June 27th lava flow field.
The breakout of lava on the north margin of the flow above Apa`a Street, near the Pāhoa transfer station, is still active, and the dominant part of the breakout was advancing at a rate of 7-8 meters (8-9 yards) per hour. This lobe was about 100 meters (110 yards) upslope of Apa`a Street at 5 PM.
DI deflation continued at the summit, having accumulated about 2.5 microradians of deflationary tilt since Wednesday afternoon. The deflation was accompanied by a several-meter (yard) drop in the level of the summit lava lake as is typical for such events. Deflation during DI events is often associated with a decrease in the eruption rate of lava from Puʻu ʻŌʻō, which may result in a decrease in the level of activity at the flow front in the coming days. An instrumental malfunction at the tiltmeter located on Puʻu ʻŌʻō is temporarily preventing an analysis of ground tilt there.
Daily updates about Kīlauea's ongoing eruptions, recent images and videos of summit and East Rift Zone volcanic activity, and data about recent earthquakes are posted on the HVO Web site at http://hvo.wr.usgs.gov.
HVO scientists will continue to monitor the flow from the ground overnight and Friday, and an overflight is scheduled for Friday morning. A daily update will be posted in the morning, and status reports will be issued as new information becomes available. Updates are posted at http://hvo.wr.usgs.gov/activity/kilaueastatus.php.
