HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE Sunday, October 26, 2014 9:32 AM HST 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 and will issue a status update this afternoon.
