The recent eruption of the Pico do Fogo continues to produce lava fountains from two vents on the volcano's flank. The erupted lava collects in rapidly growing flows that destroy roads and houses near the caldera, as shown in the new BBC footage below. ... [more]
USGS-HVO/NASA image of active flow areas on November 22, 2014.
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. [more]
Lava fountains and flow from the new eruption at Fogo (Fogonews)
