HAWAIIAN VOLCANO OBSERVATORY CURRENT STATUS REPORT
U.S. Geological Survey

Friday, November 7, 2014 5:42 PM AKST (Saturday, November 8, 2014 02:42 UTC)



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 a helicopter overflight of the June 27th lava flow on Friday, November 7, 2014. The leading edge of the flow has not advanced since October 30, but multiple breakouts were observed upslope of the flow tip. The lowest of these was active below the Pāhoa cemetery, about 450 meters (490 yards) above Pāhoa Village Road.

Several breakouts are active in the 2.5 km (1.5 mi) upslope of Apaʻa St. / Cemetery Road. One active lobe, about 150 meters (165 yards) above the road, has merged with the now inactive lobe closest to the transfer station. Another series of breakouts was occurring at the top of the narrow gulley that channeled lava towards Pāhoa two weeks ago, about 700 meters (765 yards) upslope of the road. The large lobe extending north from the Kaohe Homesteads area also continues to be active.

Overall, breakouts of lava in the distal part of the June 27th flow are mostly confined within the existing flow field, although flow margins are being extended in some areas.

Other small breakouts were observed farther upslope, including one about halfway between the distal end of the flow and Puʻu ʻŌʻō, near where lava first entered the crack system, and another on the north flank of Puʻu ʻŌʻō itself. The flow closest to Puʻu ʻŌʻō damaged some equipment that HVO scientists had installed to observe the lava tube through a skylight.

The cross sectional area of the lava tube measured Friday was 2.4 square meters (2.9 square yards). This is a slight increase from that measured last week (on October 31) and implies a small increase in the amount of lava flowing through the tube.

There was no net summit deformation over the past day. Technicians repaired the tiltmeter at Puʻu ʻŌʻō, but it is too early to tell if the work has corrected the malfunction there, as the tiltmeter requires a few days to settle before it can be returned to operation.

Daily updates about KÄ«lauea'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 observe the distal part of the June 27th flow front from the ground on Saturday. 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.
