May 23: USGS Presentation on Puna Lava Eruption So Far

Tuesday evening, USGS Volcanologist Steve Brantley gave a  presentation in Pahoa High School. A lot of it is fairly simple, recapping the eruption for residents of Puna. I’ve covered most of what he does in previous posts. But there are a few new tidbits.

His takeaway is worth seeing if you don’t read/watch the rest:

…until that balance is reached, or something else changes, we expect magma to continue moving from the summit reservoir into the rift zone and further down into the Lower East Rift Zone. So that suggests that we’re in it for the long haul. We don’t know how long this eruption’s going to last, but for now, it looks like it’s just going to continue.

May 16: HVO Raises Aviation Color Code to Red

Media freaked out overnight when Hawaii Volcanoes Observatory issued a code red alert following a 12,000 foot tall ash explosion at the summit. The next morning they clarified:

USGS Volcanologist Michelle Coombs (EXCERPT):

So we’ve had some questions about what code red means. It sounds a little bit alarming, It’s really just to say that we see significant amounts of ash from this ongoing activity, and to warn aviators about that ash. It doesn’t mean that a really big eruption is imminent. it’s really just characterizing the aviation situation.
