Update, November 24, 2018, 7:26 a.m., Pacific: Per the volcanologists, who kindly replied by email, this cloud coming out of the caldera, captured on the cam shot (below), was:
Volcanic gases — visibility of plume is more pronounced in early mornings and evenings when warm gases condense as they are released into cooler air temperatures. See this week’s Volcano Watch article for more info: https://volcanoes.usgs.gov/observatories/hvo/hvo_volcano_watch.html
We, outside Hawaii, forget that the air cools down more there, this time of year, just like where we are.
Check out the article: it turns out that local people are still dealing with a sulfur smell, only this time it’s the “rotten-egg” smell. Pelee, that’s not polite!

Update, 8:34 p.m., Pacific: Well, this is weird. Per the 6:59 p.m. note below, all is clear per VAAC; no updates on the HVO web page (linked in original post) or the Hawaii CD tweets; nothing on KHNL.
And yet I saw this on the summit cam; fortunately I saved it, because the next cam update was a black screen (night time, nothing unusual–all the other cams were already black).

It’s difficult for experts and impossible for a layperson to tell what’s going on in such scenes from just one static image, especially with such lighting. That could conceivably be weather (note the cloudy sky), but it seems to be coming up out of the summit caldera.
Well, we can but wait and see . . . and send an email to the “ask HVO” hotline. Will pass along any replies.
Update, 6:59 p.m., Pacific: About four hours ago, the VAAC issued an all-clear. No other changes; Kilauea remains at Yellow aviation code. We’ll see what HVO says in its next weekly update.
Yes, Kilauea is monitored very closely, and not just because of its Lower East Rift Zone eruption earlier this year. It’s the #1 most hazardous volcano in the US.
Original post:
Washington VAAC reports possible volcanic ash emission, perhaps mostly steam, extending 5 nautical miles from summit. HVO hasn’t updated or issued a VAN (Volcanic Activity Notice) yet. I looked at the webcams, and saw nothing that looked like remobilized volcanic ash from this year’s earlier eruptions. Nothing about it yet on the Hawaii CD Twitter feed or KHNL, either.
Here’s the current webcam view at Pu’u O’o:
That may just be typical for this empty crater in the middle of the Lower East Rift Zone just now.
All of those links are given so you can follow this, too. It doesn’t seem like a sudden return of eruptive activity at Kilauea, but you never know. Will add any significant changes today below, if any occur.
