Current Aviation Color Code: ORANGE
Issued: Thursday, September 4, 2014, 10:45 AM HST (20140904/2045Z)
Source: Hawaiian Volcano Observatory
Notice Number: 2014/H1
Location: N 19 deg 25 min W 155 deg 17 min

Area: HI Hawaii and Pacific Ocean
Volcanic Activity Summary:
On June 27, 2014, new vents opened on the northeast flank of the Pu‘u ‘O‘o cone that fed a narrow lava flow to the east-northeast. On August 18, the flow entered a ground crack, traveled underground for several days, then resurfaced to form a small lava pad.
The sequence was repeated twice more over the following days with lava entering other cracks and reappearing farther downslope. In this way, the flow had advanced approximately 13.2 km (8.2 miles) from the vent, or to within 1.3 km (0.8 miles) of the eastern boundary of the Wao Kele o Puna Forest Reserve, by the afternoon of September 3.
Overnight, lava did not appear to advance farther east within the crack system, but surface flows advanced about 100 m to the northeast. At the average rate of advancement of 250 m/day (820 ft/day) since July 10, we project that lava could reach the Kaohe Homesteads boundary within 5-7 days should lava resume advancing within the crack system.
Kaohe Homesteads is located between the Wao Kele o Puna Forest Reserve and the town of Pāhoa in the Puna District of the County of Hawai`i.
[Volcanic cloud height] SO2, low ash emissions continue from Kīlauea caldera, TFR in place.
[Other volcanic cloud information] none
[Lava flow/dome] June 27th Lava Flow continues to advance.
[Lava flow/dome] Lava Flow from Pu‘u ‘Ō‘ō vent could advance to Kaohe Homesteads within a week.
The Pu‘u ‘Ō‘ō vent in the East Rift Zone of Kīlauea Volcano began erupting on January 3, 1983, and has continued erupting for more than 31 years, with the majority of lava flows advancing to the south.
Over the past two years, lava flows have issued from the vent toward the northeast. The June 27th flow is the most recent of these flows and the first to threaten a residential area since 2010-2011.
