Today’s Eruption Summary:
Status quo continues, with Fissure 8 feeding a large, fast-flowing channel to the ocean, where it’s entering on the south side of the lava delta today. Upstream along the river, there’s occasional spillovers, but these never travel far from the levees. Top speeds on June 18 were measured at 20mph, by the way. Fissures 6 and 16 have reverted to fuming. (
I see no white speck left of Fissure 8 on the LERZ webcam [correction: it’s back at 9:45pm]). Today’s summit explosion occurred at 4:22am (5.3ish), with a minor ash plume rising 6,000 feet above sea level (2000 feet above Kilauea).
Saying Goodbye (At Least For Now)
Today’s big news was confirmation that Jaggar Museum has evacuated its exhibits:
Dramatic changes are taking place at the summit of Kīlauea. Yesterday we had to remove the artifacts from Jaggar Museum, which has endured considerable earthquake damage over the last few weeks.

Hawaii Volcanoes NPS: “The cracks on the floor are from earthquake damage. Structural damage from the quakes may have already compromised the building. The observation deck has a new and noticeable tilt. The bigger worry is the increasing and dangerous instability of the crater rim under the building.”
Meanwhile, HVO staff is “making arrangements to remove as much archival and historical material as possible from the buildings,” They’re so busy monitoring this eruption that I think they may need to hire movers:

Outside, it’s time to bid farewell to the old Halema’uma’u overlook & parking lot:

Replacement for the old North Pit GPS station that fell in, maybe?
Meanwhile, the star player and chief menace of the Lower East Rift Zone is still pumping out thousands of gallons of lava a second:
It looks like that channel to the right of what used to be “Pele’s face” has crusted over to make a lava tube, or at least a lava arch.
Last but not least, geologists on the job. This one’s a little hard to see:
We’re missing out on some of the nitty gritty details that geologists will probably be debating for years. For example, what signals can they use to detect when a fissure’s about to reactivate, if Fissure 10 has registered temperatures like this, yet it doesn’t?

More @USGSVOlcanoes Q&A
Q: Can you tell us where the overflows are?
A: It’s hard to map the smaller ones, particularly if they erupt onto existing lava flows, but the larger ones are marked in red on our maps.
Q: Are overflows still going or part of levees now?
A: The overflows that we have seen aren’t moving beyond the existing flow fields, but we are monitoring them regularly to make sure that doesn’t change. Most just flow over the levees and downhill rather than adding much to their height.
Q: How do you measure speed of lava?
A: It’s tricky! The radar gun is basically the same sort of thing police use to track car speeds, but sometimes it has trouble with very hot objects. Which can be a bit of a problem with lava flows…”
Q: Is there a graph of Kilauea’s lava lake level over time?
A: Yes, in “Preliminary Analysis of Current Explosion Hazards at the Summit of Kilauea Volcano, May 8, 2018 – Cooperator Report to Hawaii Volcanoes National Park”
Q: What’s the current height?
A: The lava lake has not been visible for some time. Geophysical and chemical evidence (in the plumes) suggests that magma-water interaction has occurred, but there has been no way to directly measure the lava lake level since early to mid-May.
Q: The ohia tree [in HVO wide-angle webcam] looks so healthy. Can they tolerate SO2 better than other trees?
A: The ōhiʻa lehua trees are very well adapted to withstanding sulfur dioxide. They’re often among the first plants to colonize new lava flows on Kilauea: [Link: Native Plants of Hawai’i]

Moment of Aloha
- Halema’uma’u 6 weeks ago: half mile across, 280 feet deep.
- Halema’uma’u June 15: 1 x 1.3 km or 0.6 x 0.8 mi, 370 m (1210 ft) deep!

There seems to be a lot of interest in my floating lava boulder video I posted earlier today. #hawaiinewsnow will broadcast it at 5 pm tonight. So I thought I would share this video, of the progression of one of those boulders as it makes its way down to the ocean. Several of these big boulders end up flowing into the ocean and then float on the surface. How wild is that. We’ve all seen small rocks floating and steaming, but huge boulders! This eruption continues to show us things we have never seen before. #lavariver #kapoho #kilauea #volcano #gbradlewis #aloha
Part I of III – 20180620 Eruption Overflight . The rising sun on Fissure 8 helped to increase visual contrast of the massive changes in landscape within and around Leilani Estates while large volumes of effusion continue downrift toward the ocean entry in Kapoho. Large lava channels continue to travel at speeds upwards of ~25mph (near Fissure 8) and 15mph (near Kapoho Cone). Converging and diverging paths of serpentine pahoehoe show signs of small breakouts with gaseous a’a surrounding northern and southern perimeters of the lava channels heading toward ocean side. Some sections of the lava channel were hit with just the right amount of angled light to reveal ribbon-like textures from the surface of pahoehoe. Surface flows and ocean entry into the waters of Kapoho continue to extend, creating new shoreline landscapes, vibrant turquoise ponds, and areas covered in volumes of laze, gas, and steam. Unique observations from this flight included lava textures and ribbon-like folds in pahoehoe, volcanic vortices (some call it “lavanadoes”), slow cooling a’a perimeters around pahoehoe channels, and interactions with high temperature lava and ocean water. Radiant heat was felt throughout the flight at 3,000ft AGL safely respecting the Temporary Flight Restriction (TFR) above and around eruptive zones. . Mahalo to braddahs @bruceomori , @mickkalber , @hotseathawaii , and Pilot Sean with @paradisehelicopters for the opportunity to join forces to document our eruption! And special thanks to @ikaikamarzo @milekalincoln and our entire Hawaii Tracker community group on Facebook for their personal contribution to help support our community and awareness on our eruption. . My respect and best wishes go out to the neighborhood of Leilani Estates, Lanipuna Gardens, and the areas within and between Kapoho. My heart especially goes out to all of my friends who have lost their homes in this fissure eruption. I am at a loss for words. . #eruption #bigisland #kapoho #lavaoceanentry #kilauea #helicopter #aerial #volcano #leilani @natgeo @hawaiinewsnow

Ha! I found one of the now gone Caldera Overtook Parking Lot. Taken from the perspective of a high point on the Kilauea Iki Crater hiking trail.
