Lava Hike (continued)
April 23, 2010
The left image looks nice and green.  The right images shows how the lava has ravaged the formerly vegetated areas.
They've pulled the gate and the viewing area back in anticipation of the lava flows coming into the previous viewing areas.  
They've got some new signs up too...
Remember this sign...
All those yellow stakes mark the trail to
the old viewing area (marked "View")

10:56 AM @ "Warm"
Looks innocent enough.  But look closely underneath.  It also feels a little too
warm...
10:59 AM @ 011
Lava nibbling away at the edge of the vegetation
This is what it looks like when the lava invades the vegetated areas.  It burns the trunks of the
trees and bushes which fall over on top of the cooler upper layer leaving a tangle of branches
and trees which can be hard to walk through.

Lava from the east rift zone vent, flowing into a lava tube system, continued to supply surface flows that have advanced slowly to the southeast
down the
Pulama pali, east of the Royal Gardens subdivision. HVO geologists in the field yesterday, mapping the flow margin, reported that
the flows continue their slow advancement on the coastal plain. The flow front was still heading southeast along the east margin of the TEB
flow field, just west of the end of the
Kalapana access road, and was 270 yards (250 meters) north of the County viewing area. The lava was
pushing through a thickly vegetated area (
kipuka), triggering small brush fires and minor methane bursts. HVO scientists will visit the flow field
Here's a map from a couple of days later with my hike plotted on it.  The dark red shows flows
as of April 22, the day before this hike, probably not much different than what I saw.  The map
was probably created as of the end of the day of the 22nd and I was out there on the morning
of the 23rd.
Another tree goes up in flames as the lava moves further into the
kipuka. Looking closely, you can see the ash from the tree in the
smoke column.

flow field, just west of the end of the
Kalapana access road, and was about 270 yards (250 meters) north of the County viewing area. The lava
was creeping through thick vegetation, triggering small brush fires and minor methane bursts. A separate flow lobe about 550 yards (500
meters) to the west was also active and approaching the forested
kipuka just north of the trail. HVO scientists will visit the flow field today to
assess the current location of the flows.

Activity continues to burn vegetation in the kipuka
Left. This photo shows the ropey texture of a
recently crusted pahoehoe flow, as well as
its superior strength as a natural insulator.
The crack is still glowing hot but the lava is
no longer moving under the crust.

Right. The activity continues to burn
vegetation in the
kipuka adjacent to the trail,
causing the viewing trail to be closed beyond
the trailhead. The new viewing area is still
very close to the active flows.
Photos are not mine, they are from the HVO image page.

Well, all of this is slow torture for me.  I get up every morning and check the status page.  Today, I finally gave in.  I got a
late start so it was just a quick hike - out, poke, and back - just to see where everything's at.  I've already got lots of
pictures of the lava on the coastal plain so it's not like I'm going to see something different...

My pictures...

This comparison of thermal images over the coastal plain shows the advancement of the active
week. In the bottom frame, from today's overflight, the thermal image shows that the flows have
migrated southeast into a
kipuka several hundred meters (yards) north of the County viewing area.

County viewing area composite and views of the active flow field

Not my pictures...
This composite image of the County viewing area in Kalapana combines a thermal image, showing the active
flow lobe in red and yellow, with a normal photograph. The lighter yellow areas are locations of active
breakouts at the flow margin, and smoke can be seen originating from the flow front where breakouts are
burning vegetation.
