For those who don't know about it, the USGS issued this press release today:
Dramatic Developments at Kilauea Volcano: Scientists Work to Keep Public
Safe and Informed
Explosive eruptions and noxious gas emissions at Kilauea Volcano in
Hawaii this week have prompted scientists to work around the clock to
understand what will happen next and how to keep the public out of
harm’s way.
Scientists are monitoring gas emissions and seismic activity at Kilauea,
which on March 19 experienced its first explosive eruption since 1924.
The volcano is also emitting sulfur dioxide at toxic levels.
The National Park Service has closed Crater Rim Drive through the south
caldera area until further notice. The U.S. Geological Survey is issuing
frequent updates, which can be accessed at http://hvo.wr.usgs.gov/kilauea/.
Sulfur dioxide emissions at the volcano’s summit have increased to a
rate that is likely to be hazardous for areas downwind of Halema`uma`u
crater. Future explosions from Halema`uma`u Crater are possible.
“This historic activity has created new hazards that did not exist
before — explosive eruptions as well as toxic sulfur dioxide emissions —
in the middle of a national park,” said U.S. Geological Survey Volcano
Hazards Program Coordinator John Eichelberger. “Our job is to give
emergency responders and the civil defense community the very best
information we can provide about what the volcano is doing and what it
is likely to do in the future.”

Just out of curiosity (not ingratitude -- the views of Halema'uma'u
and Pu'u O'o are wonderful, even if it is mostly fume just now at the
latter), is the cam that is monitoring the TEB flow area online for
the public? That was such a spectacular panorama. Of course, they've
had to move it to the summit now and the views there, when weather
permits, are wonderful.
I've been experimenting with adding numerals to the "cam" end of the
links at the above two webcams, and while one, of course, brings up
the cam at the Mauna Loa crater, no other cams have appeared. Because
tubes have formed and lava from this flow has been flowing through
them and into the sea at 3-4 points, I thought perhaps there wasn't
such intensive monitoring of the TEB flow area; but the current update
(from the 16th) mentioned incandescence seen on the field after the
4/14 deflation-inflation event so apparently some cams are covering
it. I was wondering if that might also be available to the public view
still.
It is interesting (at least to this very amateur observer) that there
is an apparently basaltic (smooth-flowing) flow from Pu'u O'o and a
more explosive eruption from the summit. If this is correct, is that
usual for Kilauea?
