Kilauea volcano update: Lava flow continues to advance towards Pahoa

The new lava flow finger from the 27 June flow continues to advance towards Pahoa and is now approx. 4 km (2.5 miles) above the intersection of Pāhoa Village Road and Highway 130, near the Pahoa Marketplace.
It is moving to the north at rates of several hundred meters per day. It has reached an area where several lines of steepest descent nearly converge due to flat topography. Until the flow passes this area of flat topography, the future flow path is uncertain. (Source: HVO daily updates)

The new lava lobe continues to advance and widen. As of this morning, it was only 4.3 km (2.7 miles) from Highway 130. A surge in lava supply resulted in an advance rate of 400 m per day! ... [details]

To present, USGS-HVO and County of Hawai`i report that lava has reoccupied the tube system only as far as the cracks near the old geothermal well site (recognized as a clearing in the thicker forest in photographs). From there, it has spilled out and is forming a new flow lobe farther west from the previous one which stopped just short of Pahoa Village Road and that now appears to be hardening without further advance. The current front is now 5.8km/3.6mi upslope from Apa`a St measured in a straight line, which means Pahoa has escaped its most urgent threat. The county is reopening the Pahoa Village Road today, previously blocked off as the power company reenforced their poles with huge piles of rock, which they have now removed again to allow the flow of traffic. While it's possible that the new flow could turn towards the outskirts of Pahoa again, it took the previous flow 7 weeks to reach Apa`a St and it's reasonable to expect a similar timeline again, keeping in mind that another flow front may develop near the breakout site nearby Pu`u Kahauale`a and divert much of the lava that could otherwise head to Pahoa. The next several days of lava activity should give some hint of an answer to the question. Finally, it may be noteworthy that there has been increased earthquake activity south of the caldera, with a 3.6 and 3.3 felt by area residents in the past 3 days. [details]

Wednesday, Nov 19, 2014
A new surge of lava over the past 2-3 days is moving through and leaking from lava tubes that until recently were feeding the eruption front in Pahoa village. Prior to the surge, the lava flow's forward progress had stalled once again with the little remaining activity both widening and inflating the flow field. It remains to be seen how far this surge can move through the pre-existing lava tube towards Pahoa, having so far travelled "about 11 km (7 mi) in a straight line distance downslope of Pu`u `Ō`ō" according to the County of Hawai`i and USGS-HVO.

An upper branch of the active lava flow has advanced roughly 375m/400yds over the past 2-3 days to within 300m/325yds of Apaʻa Street, on the other side of the recycling & waste transfer station. ... [details]

Yesterday, lava flowed across the fence at the Pahoa transfer staion, a recycling and waste facility at the edge of town and across the street from the first residence which burned the day before. USGS-HVO reports that lava is currently filling the low area around the center of the facility, which had already been largely dismantled and relocated. ... [details]
