We had relatives visiting last week and my brother went on a helicopter tour. He came home with a dvd of the overflight. The lava flow is really impressive and then it dumps into a tube--a lot of lava going underground. It has to come out somewhere...
If you try to match the current location of the lava with the descent paths included in the "Lava Flow Hazard Assessment," http://pubs.usgs.gov/of/2007/1264/ it looks like there is a big ridge to cross before the flow would head south to the coast.
And lava flows change a lot. I just got the dvd "Lava Flows and Lava Tubes" and it is very interesting. Highly recommended.
