I didn’t realize I’d missed one of Steve Brantley’s excellent 10-minute slideshow presentations at the weekly Puna Community Meetings. This one took place on Tuesday, June 12 at Pahoa High School.
I learn something from every one of these talks, which sum up Kilauea eruption activity of the past week in a way that’s easy for the general public to understand without talking down to them.
Video of meeting is archived here. Steve’s presentation starts at timestamp 42:10. Where possible, I’ll be including images in my transcript which match his slides.
(Steve Brantley is a USGS geologist, deputy-scientist-in-charge of Hawaiian Volcano Observatory.)
Hello everybody. Thank you for coming out again and thank you for your perseverance. I’ll show a couple slides of what’s been happening down in this part of the neighborhood and end with some slides of the summit area, which continues to change very dramatically.
So this is the overview slide I’ve showed for the past few times. It gives you the overall picture. It’s an image, cartoon, from the summit area all the way out to the eastern tip of the island. The summit area here [under “Kilauea Caldera” label], eastern tip [down by “Kapoho Crater”], with a cross section showing you the general picture of the magma reservoir system from the summit of the volcano down through the East Rift Zone and into the Lower East Rift Zone.
At a 3PM press conference, Jim Kauahikaua (USGS geophysicist) described in detail the subsidence at Halema’uma’u. He also talks about a patch of “upwelling” where lava has entered ocean at Kapoho and seems to be traveling along ocean floor, heating water above it.
