HAWAIIAN VOLCANO OBSERVATORY CURRENT STATUS REPORT
U.S. Geological Survey
Tuesday, December 9, 2014 8:49 PM AKST (Wednesday, December 10, 2014 05:49 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
USGS Hawaiian Volcano Observatory (HVO) scientists conducted an overflight this afternoon, mapping and observing the entire length of the active lava flow erupting from Puʻu ʻŌʻō. The active lobe that branched off the west edge of the flow field downslope from the crack system has advanced about 300 m (330 yd) since December 7. During the past 2 days, the average advance rate is 150 m/day (165 yd/day), which is less than half the advance rate of last week.
The leading edge of this lobe was 3.4 km (2.1 mi) upslope from the intersection of Highway 130 and Pāhoa Village Road at the Pahoa Marketplace. Along its length, the width of this lobe varies between about 80 m (90 yd) to 330 m (360 yd). The active lobe is following a steepest-descent path that takes the flow towards the intersection of Pāhoa Village Road and Highway 130, in the vicinity of the Pahoa Marketplace.
In addition to this active lobe, a breakout from the lava tube on December 5, about 2.6 km (1.6 mi) from Puʻu ʻŌʻō remains weakly active. The breakout is about 1 km (0.6 mi) long, and has widened the flow field in this area by about 200 m (220 yd).
During today's fieldwork, HVO scientists also measured a slight increase in the cross-sectional area of the lava stream within the tube near Puʻu ʻŌʻō compared to measurements made on December 1.
Daily updates about Kilauea'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/.
