June 8: A Voggy, Voggy Day

Today’s eruption summary

…Status quo continues another day.

Kilauea, HI - East Rift Zone Eruption Event - 06/08/18 Photos and Video

Fissure 8 continues to do its thing (fountains up to 230 ft today), pumping a vast river of lava towards Kapoho. Its flow front is about a mile wide where it meets the ocean. USGS reported ~190 acres of new land added to Hawaii as of noon. Some or all of this may be temporary, since “lava deltas” tend to collapse.

Kilauea, HI - East Rift Zone Eruption Event - 06/08/18 Photos and Video

[Above: 2 photos from Hawaii County Fire Department’s extensive videos/photos for June 8. Good to browse if you’re checking on homes in Kapoho.] 

Summit activity continues to follow its geyser-like cyclical pattern. Earthquakes increased until 2:44 AM, when there was an explosion (equivalent of M5.4), after which seismicity died down.  Pu’u O’o also had a small earthquake (3.2) and rockfalls today, sending up a red plume of ash. (Still hunting for photos, but it’s been reported several places.)

USGS: “Outgassing from Halema‘uma‘u produced twin pillars that rose in the still morning air and merged into a towering cap above the summit of Kīlauea just after sunrise.” (Full-sized)

East and southeasterly winds sent an unpleasant amount of vog over Hilo and the Saddle. This will continue through Saturday, then tradewinds come to the rescue.

Today’s Kilauea Alerts, Videos, Images, and Eruption News

USGS: “Dramatic changes at Halema‘uma‘u could be seen through gases rising from the crater during HVO’s overflight of the summit this morning at 10 a.m. HST. The view here looks to the southwest, with the former overlook parking lot barely visible to the left of the gas plume.” (Full-sized)

HVO – Kilauea Alert – 2018-06-08 06:05:32
“At 2:44 AM HST, a small explosion occurred from Kīlauea’s summit. PTWC magnitude is 5.5, but shaking was equivalent to a ~M4 event. No radar observations*, but satellites suggest any plume is less than 10,000 feet ASL.”

*[NWS Hawaii radar broke. Waiting for replacement part, hoping to be back up  by end of weekend. Plumes <10K feet are hard for satellites to detect.]

After explosion, seismic activity dropped. S02 emissions lower than early-mid May but still high enough to cause problems downwind.

Civil Defense Alerts: the usual evacuation orders, shelter notices, and volcanic hazard warnings, plus a special vog warning and reminder there’s a new air quality map one can check. (6AM |9AM (corrects curfew mistake in 6AM)| 1PM | 6PM  )

Today’s Lower East Rift Zone Lava Map

USGS Map of LERZ: “Map as of 12:00 p.m. (noon) HST, June 8, 2018. The fissure 8 flow has created a lava delta approximately 190 acres in size, filling Kapoho Bay and shallow reefs along the nearby coastline.” (Full-sized)

11AM USGS conference Call

Paraphrase/excerpts (timestamps from full unabridged audio) :

ERUPTION SUMMARY by Steve Brantley, Deputy Scientist-in-Charge HVO [timestamp 02:30]: Fissure 8 eruption continues as it has 1-2 weeks. Ocean entry flow front almost a mile wide. Summit explosive event 2:44am. Followed 12-24 hrs increased seismic activity. Similar to seismic pattern of past 1-2 weeks. Accompanied by additional subsidence (10 ft) of crater floor [does he mean caldera?] right next to  Halema’uma’u crater rim. Common for these events. “Downdropping as well as slumping towards Halema’uma’u.”

Q&A first question: Do you see anything in Mauna Loa’s activity to be concerned about?  [09:00] Steve: Mauna Loa activity decreasing over past year, no impact whatsoever from Kilauea.

[Note: people keep badgering the USGSVolcanoes Twitter about supposed increased activity at Mauna Loa, sometimes posting an earthquake chart they claim is from Mauna Loa, but it’s actually a chart of Kilauea seismicity, which one can tell at a glance since the peaks on the graph match the times of Kilauea’s summit ash explosions. This conspiracy theory needs to die.]

Q on subsidence at Halema’uma’u [11:00]
USGS Geophysicist Ingrid Johanson: The large amount of subsidence seen at that GPS station [10 foot drop mentioned earlier] mainly related to blocks slumping into Halema’uma’u Crater. We’ve seen other blocks drop tens of meters as they’re falling in. So essentially, that was landsliding rather than deflation of summit reservoir.

Q on whether new fissures could open [19:30]. Steve says yes, although right now activity is at Fissure 8. But old fissures could reactivate, new segments/fissures could form. Added postscript about how USGS is monitoring cracks (extension, widening, temperature, steam) to watch for signs of new fissure eruptions. No change lately.

HVO/USGS Answering Questions On Twitter

USGS reply to  why they’ve released “very few photos & other media”:

“Some of it is because of sensitivity – we’re trying our best not to release anything that shows homes burning, for example. We don’t always get appropriate broad overview photos from our field crews because they’re busy collecting data, and we can’t hassle them too much. (1/x)

“Our media team is also busy fielding calls, interviews, maintaining the website, answering social media questions, taping updates, writing reports – and we are spread from Hawai’i to Virginia. Sometimes we’re just swamped! We’re doing as much as we can at the moment. (2/x)

“We do appreciate that people are anxious to see what’s going on in the eruption, and we try to select media that gives as much information as efficiently as possible. So while we are collecting lots of photos and video, we may only post a small portion of it at one time. (3/x)

“Eventually, all of it will be archived and available to the public, but it may take some time. (4/4)

[followup to comment that other people are showing such photos.]

“It’s good these are being provided by other outlets. We have guidelines relating to showing burning homes, and it’s important for us to remain sensitive to those who have, in the past, expressed not wanting those images to be broadcast by us.”

On the Kapoho ocean entry:

“Yesterday flight conditions were difficult and there wasn’t a great deal of change in the flow front above water – we think that there’s underwater lava advance going on, but we can’t map that from photos.”

It’s “Too early to tell!” whether Cape Kumukahi will remain Hawaii’s easternmost point.

USGS overflight video of Pu’u O’o

On whether Pu’u O’o might refill:

“We really can’t tell. We can track magma movement in the shallow subsurface, and even somewhat deeper, but we don’t know if new magma from #Kilauea‘s summit reservoir will refill #PuuOo.”

And in answer to someone’s question about possible Pu’u O’o activity today:

“A rockfall and small plume of rock dust rose from the crater today. Likely it’s just caked rock dust on the lens.”

Which explains what we observed on the Pu’u O’o webcam today (and two days ago):

Articles From other Scientists
  • LivesScience’s “The Science Behind Hawaii’s Surprising 2018 Volcanic Eruption” is a daily summary of the eruption through June 4, with a short paragraph and one photo for each day.
  • Dr. Robin G. Andrews has been  posting delightfully readable articles on Kilauea. Some articles I’ve linked to; others are geared more towards normal people who don’t obsessively check HVO webcams to see what Fissure 8 is doing. Either way, this is a fun thread which also sums up the current eruption with a few short cat gifs.
  • Dr. Jess Phoenix, the geologist who ran for a California congressional district but got edged out Tuesday, jumped right back into teaching with a quick Twitter thread on the current Kilauea eruption.

We conducted an aerial survey in the Temporary Flight Restriction (TFR) to document the current status of incandescent lava flows over and around the corners of Kapoho, Lanipuna Gardens, and Leilani Estates. Kapoho ocean entry showed signs of advancing lava, glowing gas, steam, and particulate (laze) while the expanding 1.2mi wide delta continued to push north upwards to Kapoho Beach lots. Several channels of lava continued to combine and separate throughout pathways from Fissure 8 with little visual deviation from lava flow maps produced from today. Fissure 8 bellowed significant amounts of gas while lava continued to fountain at ~50-100ft heights while pouring vigorously out of the eastern flank, feeding flows toward the ocean. .
