Fountaining & active lava flows on the floor of Nāpau Crater.

I took this photo a month ago from the top of Pu’u Huluhulu.  Eruption started about a mile (?) away in field of view. (No eruption in photo)

No, sorry Edge, from the top of Pu’u Huluhulu you can't see that far directly.. the rise created by the Makaopuhi crater / Kānenuiohamo cone structure (the cone/mound in the middle ground of your pic - the one covered in foliage). The eruption is taking place between that complex and the far cone in the background of your pic which is Puu Oo.

Here's a map from HVO's site.. with Makaopuhi crater / Kānenuiohamo cone seen (partially) on the left, and Nāpau crater on the right, and Puu Oo is still a mile further to the right than the area seen here..

The interesting thing to note is phase 1 of the Puu Oo eruption was also at this same location. In other words, this is the first sign of a possible reoccupying of the Puu Oo plumbing system..
