May 18: “Fresher, Hotter” Magma Arrives, HUGE Fountains Begin

Thursday May 18: Fissure eruptions went into overdrive [Good article from Star-Advertiser] as “fresher, hotter magma” (Janet Babb, USGS geologist) arrived from summit. Fissure 20 released a lava flow down toward coast, crossed Pohoiki Road, and isolated about 40 houses. Four cut-off residents were airlifted out.

Here’s an archived livestream by Honolulu Civil Beat starting before dawn Friday morning:

Check out daylight screencap from late in the broadcast to get sense of scale: note house.

The USGS also posted a brief video clip of Fissure 17 in its Kilauea-Iki-like glory:

May 19, Friday afternoon, a new livestream started from same channel  as before (civilbeat.org). They streamed through most of the night, occasionally shifting view from large fountain behind house (Fissure 17) to lava flow and a group of lava fountains building spatter ramparts (Fissure 20 merged with others) upslope to the right.

Friday, HawaiiNewsNow’s Milika Lincoln filmed same area in late morning from nearby location, near Lanipuni Gardens: fissure 17 fountain was now 500 feet tall. There seems to be a crater (pu’u) forming to the right of 17’s fountain. She also interviewed a resident who saw Fissure 17 form— as they talk, it roars. After dark, her crew’s footage is absolutely spectacular. (She’s calling it 19— either I’m mistaken about which one she’s watching, or she is.)

You can really tell this is hotter, fresher, more voluminous lava that drained from Pu’u O’o, as opposed to the old, stiffer, cooler lava that erupted from fissures in Leilani Estates the first two weeks of this eruption.

“Ground deformation is continuing with increased seismicity” in Lower East Rift Zone, and USGS warn lava inundation below them is possible, and that more fissures could still open uprift or downrift. “All fissures are actively spattering or actively degassing.” 40 structures lost.

May 13: Fissure 17 Starts

I’ve not covered every single fissure: see the HVO Photo/Multimedia blog, the HVO timeline, KITV, and HawaiiNewsNow for fissure-by-fissure coverage, not to mention HNN reporter Milika Lincoln’s Instagram vids and photos, and Mike Kalbers’ wonderful daily flyovers.

Activity ebbed and flowed, some days with more steam, some with more spatter. For the most part, lava flows didn’t go very far, and were largely sticky, clumpy, clanky a’a. But I bookmarked fissure 17 early on for particularly dramatic fountains (those blocks it’s hurling are called “lava bombs”) and incredible booms and roars:

#LeilaniEstatesEruption LATEST (May 15 at 8:30 AM): Incredible new sunrise footage captures the sounds and sight of lava fountains and gas bombs erupting from the 17th fissure — which broke out Saturday off of Halekamahina Loop Road northeast of Lanipuna Gardens on the Kalapana side of Highway 132. According to USGS HVO scientists, fissure 17 has created a narrow lava flow heading makai — or downslope toward the ocean — and has already covered about two miles. Civil Defense officials say based on their last measurement, this flow front is now a little less than a mile from Highway 137. At one point yesterday, it was moving at a rate of about 100 yards an hour, but it has since slowed a bit. The flow has been running roughly parallel to Highway 132 or Pahoa Kapoho Road. Officials say it's heading east in the direction of Kapoho toward Highway 137 — also called Old Government Beach Road, or more commonly referred to by residents as Waa Waa Road. This fissure has already claimed one structure — but officials say there are currently no homes or buildings in its current path. This has been the longest-lasting, most active fissure of the 20 that have opened up since this the first on May 3 along Mohala Street within #LeilaniEstates.

and it was the first one that really seemed to be making a run for the ocean and creating a sustained lava flow.

Here’s May 13 and 14th flyovers from Mick Kalber:

Luckily, it chose a route that doesn’t have many houses downslope. And unlike other fissures, it just kept going and going.

And (since I’m posting this backdated): it’s still going on May 19, after making quite an impressive lava fountain and cinder cone for itself over the past two nights.

May 7-9: Fissures Slow Down (For Now)

Fissures continued to open, but mostly emitted slow, sticky lava that didn’t travel far. Leilani residents continued to be allowed back during the daytime.

Video: lava flow eats Mustang (dead battery; owner left it to focus on rescuing other possessions), another flow pushes through metal gate.  These slow-moving, clumpy, clanking flows that pile up like a rocky bulldozer are “a’a” lava.

May 4: USGS Scientist Explains First 24 Hours of Eruption

HVO Scientist-in-Charge Tina Neal gave an EXCELLENT evening briefing on the first 24 hours of the Leilani Estates Eruption, explaining very clearly what was happening and why.

[Big Island Video News, overlaid with video from Mick Kalber flyover]

Powerpoint slide summary of TALK:
  • 6 fissures in first 24 hours — more are expected
  • No lava flows extending more than tens of yards so far — flows are expected
  • Magma intrusion into LERZ [Lower East Rift Zone] is continuing
  • High levels of sulfur dioxide gas [SO2] near fissures and downwind
  • More Magnitude 5+ earthquakes possible as volcano adjusts to intrusion
Excerpts from this Briefing:

May 4: First Full Day of Eruption, 6.9 Earthquake

Friday was a busy day. Starting before sunrise, more fissures erupted (USGS night video). Here’s a USGS video of Fissure 3: first cracks, then steam, and eventually lava spatter.

At 12:33PM. a magnitude 6.9 earthquake knocked out power to some customers, agitated the summit lava lake (video clip), sent up yet more ash from Pu’u O’o (video clip), and caused minor local sea level fluctuations (Good article: Honolulu Star-Advertiser). Also see informative HVO Volcano Watch photo essay.

Below: Interview of HVO geologist Jim Kauahikaua, prior to 6.9 quake. Big Island Video News added lava footage from David Corrigan, Mick Kalber, Ikaika Marzo.

May 3: First Fissure Eruption Begins

After 2 days of earthquakes and cracks indicating magma was moving down the Lower East Rift Zone, the first fissure opened in Leilani Estates at about 5PM HST, Thursday, May 3, 2018.

Big Island News posted a 10PM video update with video footage accompanying a May 3 civil defense advisory:

Leilani Estates is about 11 miles downrift from Pu’u O’o, in the Puna District.

May 1: Pu’u O’o’s Pink Ash Plume

On May 1st, the night after Pu’u O’o’s floor fell in, the newly-drained crater was sending up a huge plume of pink ash.*
