Kilauea volcano update: Lava flow again approaches Pahoa, threatens commercial heart
Tuesday Dec 16, 2014 10:46 AM | AUTEUR : T
Lava flow map as of yesterday (USGS)The active lava lobe that has been advancing along the northern flow margin of the lava flow that had entered Pahoa in Nov, but then stopped, continues to advance towards the town and is now only approx. 1700 m away from the commercial center of the town.
Its speed in the past days averaged about 250 m, i.e. it could reach Pahoa in about a week if it continues at this speed and if it continues to follow the path of steepest descent. This path, calculated by HVO, would intersect the main road near the supermarket.
According to a local press article, the staff of the supermarket will begin to evacuate it and close it to the public Thursday evening. The gas station will be closing on Friday.
If the scenario becomes reality, the lava flow would hit the commercial heart of the community. Civil Protection spokesman said that it would be the worst loss during the eruption since its start in 1983.

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]

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.
