This two-minute video is what I shot on February 24th, 2012, as detailed in yesterday's posting
The gushing rivers are from a rupture in the lava tube feeding the flow front, which is a mile further down the pali from here. Lava is being feed from the Pu`u O`o Crater located four miles to the northwest; Kilauea Volcano's most active eruption source since 1983.
Click on the 'Tube' of YouTube on the bottom right to watch this in larger sizes on their site.
The a`a lava is that rough jagged stuff that crashes itself down the mountain. At the end of the vid are a few slow breaking pahoehoe toes, as they are termed. Those silver-gray lava forms were just cooling and soon after filming they burst alive again as surface lava.
Lava tube rupture forks out the top at rapid speed.
This lava is still over two miles from the open ocean, and does not threaten any homes at this time, though Jack Thompson, whose home is within the tattered fragments of what was once the Royal Gardens subdivision, does have reason to be concerned because there are sprawling breakouts of surface lava above his forest kipuka. It is too early to gauge if that more westerly branch of this large flow field will move down into Jack's area. Forests are burning adjacent to the east, and far above, his place now though.
