USGS/Hawaiian Volcano Observatory caption for this image (full size image here), with emphasis added:
This wide-angle photo shows the fissure 8 cone (center of image) and the long line of steaming areas extending uprift (west), towards the upper right corner of the image. No significant change was observed at fissure 8 during today’s overflight. Thermal images (see inset lower left) show no signs of lava within the cone – the small collapse pit in the center of the crater floor is cold.

HVO/USGS Volcanic Activity Notice
Volcano: Kilauea (VNUM #332010)

Previous Aviation Color Code: ORANGE
Issued: Friday, October 5, 2018, 8:47 AM HST

Volcanic Activity Summary: It has been 30 days since lava has been active at the surface of Kīlauea Volcano. HVO monitoring shows low rates of seismicity, steady, relatively low rates of deformation across the volcano, and only minor gas emission at the summit and East Rift Zone (ERZ). These observations indicate that resumption of eruption or summit collapse is unlikely in the near-term.
Accordingly, HVO is lowering the Volcano Alert Level for ground based hazards from WATCH to ADVISORY. This means Continue reading
There has been a slight, but possibly very important, change in the eruption–less lava coming out in the Lower East Rift Zone and a hiatus in summit collapse events–and I’m updating the Kilauea eruption page again. Can’t spend a lot of time on it because of book work, but I’ll try to catch the important stuff. Right now it’s mostly waiting to see the next pronouncement from USGS/HVO.

You’ve seen plenty of video of the lava flowing in the LERZ, so here is a USGS video of a summit collapse event about two months into the eruption. It’s not dramatic to look at–just trees shaking as the seismic waves roll through–but it is every bit as much of a caldera collapse as something CGI’d in a supervolcano movie.
Only it’s in real life, and happening so slowly that we can watch it in relative safety, while carrying on with our lives as usual nearby. And there hasn’t been one of these otherwise daily occurrences since August 2nd; it may never happen again our lifetime. (Then again, it might–you can’t be sure of anything around Pelee!)

Now let’s go back in time about half a century.
Hi! Thanks for your interest. The updates now have their own page. (You can also click on the menu at the top of this page!)
Vog is volcanic smog, and thanks to Kilauea’s longstanding eruption, there’s a lot of it in Hawaii right now. But this video from the University of Hawaii also shows somebody climbing a snow-covered volcano, and someone else snowboarding. In Hawaii. Cool!
