Today’s eruption summary

Exactly 8 weeks after the Lower East Rift Zone eruption began in Leilani Estates on May 3, Fissure 8 continues to gush unabated. Its fountains are contained within its 55-meter (180 ft) cone, and this morning’s overflight showed no active overflows.

For the past day or so, the lava river has crusted over on the last half mile to the ocean. This has allowed lava seeps, described by Steve Brantley in his Tuesday evening  talk, to creep into still-molten earlier flows on the northern side of the lava delta. This “lava seepage” is oozing into the ocean along a broad front, encroaching  onto what’s left of Kapoho Beach Lots on the northern edge of the flow:

USGS: “View of the ocean entry (lower left) from this morning’s overflight. Lava was entering the ocean across a broad area primarily on the north part of the lava delta. Upslope along the northern margin of the flow field, lava is still oozing from several points in the area of Kapoho Beach Lots. Fissure 8 lava fountain in the upper left. Note southward bend in the lava channel around Kapoho Crater.” (Full-sized)

At Kilauea’s summit, the most recent collapse explosion occurred at 4:49am this morning, sending up an ash-poor plume about 1000 feet, with the energy release of a 5.3 earthquake. The sides of Halema’uma’u continue to collapse inward and downwards, especially during each explosive event.

Increased seismicity in the hours leading up to each explosion, up to 25-35 small earthquakes an hour, is wearing on the nerves of nearby Volcano Village. The USGS is meeting with them tonight to talk about the ongoing earthquakes, and released an excellent FAQ today: “Frequently Asked Questions About Kilauea Volcano’s Summit Earthquakes.”

Local News Outlets Given Brief Tour of Summit

The big news today is that the National Park Service and USGS arranged a brief escorted tour for local news media to the rim of Kilauea Caldera, which has been closed to visitors for 49 days. There was also a half hour press briefing.

So today there’s suddenly a lot more videos and views of what the caldera looks like:

In fact, I’m going to put the news media links before the science segment of today’s post. Boldfaced articles include quotes, videos, and/or photos from the media summit tour.

June 26: Steve Brantley’s Tuesday USGS Presentation

On June 26, 2018, Deputy Scientist-in-Chief of the Hawaii Volcano Observatory, Steve Brantley, gave a ten-minute slideshow at the Puna Community Meeting in Pahoa. Video of the meeting is posted here. Steve Brantley’s talk starts at 35:00 in that video.

BigIslandVideoNews excerpted half of his talk in this video, which they overlaid with footage from a June 24 USGS drone overflight of the summit:

Below is my transcript of the complete talk, including images that match or approximate his slides.

Steve Brantley (USGS):

Hello, everybody. Thank you for coming out.

I’ll just describe a few things occurring in the Lower East Rift Zone and then summarize the activity up at the summit at the very end.
