So it's just like getting permits.
Okay that's a good one!
So now there are three...

Seeb - good question about the pyroclastic flows. I haven't come across a map but I think the party of Keoua's warriors killed in the 1790 event were just mauka of Kilauea Caldera headed west. The "footprints" area of the park to the west of the caldera was affected as well. I found this article with basic info. If you click the link to the paper the abstract discusses the Keanakako'i Tephra deposit - thought to be from this event and how it matches up with accounts from survivors taken 46 years afterward. Of course what happened then may not repeat exactly.

What's really necessary ("for science") is a sample of the water, which will suggest its origin.
Seems trivial to send down a drone, assuming such an expedition is both permissible (by law) and allowed (by culture).

New imagery released today - photo, thermal and video from HVO. Larger bottom pond was 158 degrees Fahrenheit.

Wouldn’t it be neat if a large lake developed over time (of course not as hot though #129397;!)? I’m thinking of places like Crater Lake in Oregon!

Hmm, water boils at 212 degrees Fahrenheit, yet the pond is boiling at 158 degrees Fahrenheit. Perhaps this is a clue as to the minerals dissolved in the water and the source.

If in fact it actually is boiling and not just a sensationalist headline. The article itself makes no reference to boiling, just "steaming and rippling".

Seems to be a swarm of minor EQ at the top (40 last 24hrs.) and a bit of increased deformation. Wonder if Pele is stirring up the pond.

The "boiling" could also be de-gassing of the underlying magma - think carbonated springs...
Also, keep in mind that the thermal imagery just "sees" the top of the water column and so it could be bubbling below, but the surface of the pond could be a bit cooler. There was a thermal spring in Yellowstone (may still be there) where steam "bubbles" would enter the bottom of the pool but immediately collapse because the water in the pool was cool enough to condense the steam as soon as it was exposed to the water column.
It will be interesting to see how the pond evolves - some crater lakes (at active volcanoes) actually form a two-phase system: the magmatic gases condense and form a pool of elemental sulfur at the bottom of the lake with a hot water lake on top of the sulfur lake.

"Boiling" is a verb and applies to "the action of bringing a liquid to the temperature at which it bubbles and turns to vapor". Once it reaches 212 it becomes either an adjective or a noun depending on how cranky your third grade English teacher was / is.
