Roads-end ‘viewing area’ extended closer to newly cooling lava ~ Active lava about the same

(Click on the image for a larger size in a new window)

As previously reported: active pahoehoe breakouts continue along with swelling of the hot flow fields at many locations of the April-May surface flow. The coastal entry points have changed somewhat in the past 48-hours, but are still emptying a lot of lava into the sea as new deltas area being rapidly built. The entire length of the ocean entry and all land adjacent to it inland is quickly becoming unstable and should be kept well aware of from now on.

Visitors that walked the mile from the Hawaii County roadside parking lot to the end of highway 130 designated lava viewing site last night reported seeing the most activity from the road itself, rather then the designated viewing area set up at the lava-covered terminus of 130. While walking the road they report seeing a distant steam plume where lava pours into the sea, which sometimes glowed orange-red after dark; an occasional flame-up of distant trees burning from lava, as well as some lava glows on the distant pali, again, after dark. There was no active lava visible from the designated ‘viewing area’ that I am aware of. But just beyond the new end-of-the-road viewing area lava is still breaking out in places.

USGS lava flow map gives a good indication of the active lava zones:

And a new USGS image page has this good aerial of the lava off the (new) end of highway 130:

Below are previous posts, which remain relevant as far as the overall lava activity picture.

Lava continues well supplied from the eruption site near Pu`u O`o crater down the Pulama Pali; spreading out with active branches across the coastal flats and into the ocean in several locations along a quarter-mile of shoreline very near the old Waikupanaha entry point.

On the coast, pahoehoe continues actively flowing directly adjacent to the older Waikupanaha public viewing site; within 10-feet on the west & south sides and is now nearly level with that old viewing site. Much of the trail leading to this site is now covered in new & still hot lava.

The Pulama Pali continues hosting some active advancement of new surface lava comprising of both A`a and pahoehoe. This latest flow may have burned into the April lava tubes and re-energized them.

Above is a rough map with my added notes of the present lava situation (May 4th, 2010; lava has advanced beyond the marked in yellow locations in some places) on the coast of the Big Island. The aerial photo is from the April 28th, 2010 USGS image site.

And my most recent days postings for May, 2010

I will keep this as my main posting update layout in the coming days, adding new headings and images as lava events warrant.
