Every day is a little different, as it should be. A misty morning
here at Keaʻau ma uka. The fresh, lime-green fronds of hapuu droop
with the weight of mists and light rains, and apapane sing.
Iʻve attached images regarding the following.
1. Yes, effective 10p tonight HAVO will close indefinitely. It's
important to remember that they are closing as a safety precaution,
and NOT because they know that there will be explosions this weekend.
We think we know what the ash emissions and the lowering of the HMM
lake portend, but until a phreatomagmatic explosion (powered by gases
and steam) happens, we can't know for certain. So read, learn, get
prepared, take a deep breath, and wait and see.
2. It's likely that pulses of ash-laden clouds at HMM will continue.
They first happened in March 2008, when hoʻopuka Pele ma Halema'uma'u
(when Pele emerged at Halema'uma'u). See attached photos. Note that
her lua hou (fresh pit) was small in diameter, and so of course the
ash plume was narrow at the base. Too, note the lithic tephra (rocks
that fell from the sky during an initial explosion) that cover the
ground and destroyed part of the fence at the Halemaʻumaʻu Overlook.
2B. TILT at UWE (the tilt meter in the vault near Uēkahuna, across
the street from HVO and Jaggar Museum), continues its steady decline.
We pray that it turns and either flattens out or rises. The declining
tilt is tied to the lowering of the HMM lake. Not good.
3. WEBCAMS: The HMM Thermal Cam is off. The best one now is the KI
Cam, first on the list at https://hvo.wr.usgs.gov/cams/
It's raining in Keahialaka at Leilani Estates, and so the view from
the PG Cam is obscured. According to CD, Fissure 15, the most recent,
has paused.
4. EARTHQUAKES (ʻŌLAʻI): See the USGS Report I sent you yesterday
afternoon, and the two attached EQ maps. Just after 6p yesterday, May
9, it appears that the dike intruded further downrift, northward,
crossing underground HWY 132, the road from Lava Tree State Park to
Kapoho. Fissures in 1955 erupted across that segment of road. Again,
read Macdonalds report of the 1955 eruption.
Stay informed and be safe. I apologize if I omitted anything. If so,
ask and Iʻll respond.
