Lava Report: Watch Out, Malama Market

The lava has taken off in a new direction–and the path of steepest descent on Hawaii Volcano Observatory’s latest map leads straight to Pahoa Marketplace and the head of the Pahoa bypass.

The new map shows a long, narrow  extension of  the flow taking off on a more northerly route, while the leading edge that burned one house, nearly inundated the transfer station and threatened Old Government Road (Pahoa Village Road) continues to cool.  The “path of steepest descent,” marked by a dotted blue line, marks the steepest gradient  ahead of the flow and the path that the flow is projected as most likely to follow.  But it should be kept in mind that the steepest gradient is not always that path that lava follows.  It can build its own dams, cut down to older  lava tubes–or get cut off by a tube system blockage or breakout further uphill,  as happened with the flow that nearly reached the road last month. HVO notes that with the current lava tongue,  two possible paths of steepest descent nearly converge at one point in a relatively flat area where the lava could easily meander.  If it diverts to the second path, that could take it even further north, toward Hawaiian Paradise Park.

If this new path becomes the main flow–and Civil Defense is already calling it the “new flow front”–then that could substantially alter the county’s disaster planning.  The good news is that there might not have to be parallel facilities for “North Pahoa” and “South Pahoa.” The bad news is that the lava flow could be even more destructive,  threatening the the newly built up area around the intersection of the bypass and the old road, with its shopping centers, the new police and fire stations, and the area’s largest supermarket–and could cut off  a an even larger population.

As of this morning, both HVO and Civil Defense placed the flow 2.9  miles above the junction of  Old Government Road and the bypass at the Pahoa Marketplace.  The current leading edge of the flow was within about .6 miles of the flat area where the possible paths converge.  ” Until the flow reaches this area, it is not clear which path it will eventually follow,” notes this morning’s HVO report.  HVO did not give an estimated speed for the flow this morning, but Civil Defense reported that it had advanced about 400 yards since yesterday.

    I think Pele thought the roundabout project was taking too long and that the fast food workers deserve a living wage.

    Great insightful article
    Lower Puna is grandly diminished w/ the summer hurricane, Tutu Pele’s lava flow & the Tiffany Edwards-Hunt political loss !!!
    The BIChronicles is my link from NYC to the BI, thanks many times over
    I hope Pahoa will continue to be an active capital for the Punaverse…hope to see you all in Oct again
    Be well … All of us
