Status quo. No significant overflows today from Fissure 8’s lava river. USGS morning overflight put the southern margin of the coastal flow field at 500 m from boat ramp at Isaac Hale Park. In other words, not much movement in that direction.
Summit collapse occurred while I was writing up this post, as expected: 8:54 pm HST, back to an energy equivalent of M5.3 on reviewing readings, they upped this one to 5.5! Let’s see whether that results in an early-morning Fissure 8 surge tomorrow, er, today, Monday.
When the National Park opens again, they’re going to have a new— or rather, very old— landmark that I confess I’m rather excited about, although it’s not quite as photogenic as a lava lake. Mark Twain would’ve seen this during his visit in 1866:
As we approach the 3-month mark, the USGS is beginning to supplement its daily reports on the eruption itself with recognition of scientists and support crew who have been working 24/7 to monitor, collect scientific data and inform civil defense and the public since this eruption began. The drone crew worked overtime last night after being grounded by weather then night before:
Two maps today, one assembled from yesterday morning’s overflights and one from 2 o’clock this afternoon:
Fissure 8’s lava flow has settled into its new course, turning right just before Kapoho Cone and proceeding south-southeast to the ocean in a strong channelized a’a flow. Some lava, apparently following the earlier paths (lava tubes, maybe?) to the sea, is still squeezing out of the broad 6km (3.7) mile lava delta to the north of the new ocean entry.
A fascinating footnote: while the northern “ooze-outs” are weakening, a tiny lava island popped up just offshore of them last night, and it is itself oozing lava:
Today’s summit collapse occurred at 7:06pm HST, with the energy equivalent of a 5.3 earthquake, as usual. HVO is setting up a new livestream from Volcano House, but it’s not fully operational yet, so we made do with the ailing HVO webcam today (video clip).
Kīlauea Message Fri, 13 Jul 2018 21:53:34 HST: Following the 19:08 HST summit collapse explosion today there was an increase in activity from fissure 8 resulting in channel overflows on the south side of the flow near the vent.
Also, we’ve got a new view of ever-expanding Halema’uma’u Crater in Kilauea’s summit caldera this morning:
I couldn’t find a comparable aerial photo with the observatory and Jaggar in shot, but this 2009 photo of Halema’uma’u is facing in approximately the same direction. (Look for Crater Rim Rd behind the crater on the left, and note the parking lot obscured by the lava lake’s plume in 2009— lava lake, parking lot, and part of that road collapsed into the crater in June.)
News media have finally gotten wind of Civil Beat’slivestream. Some have gotten the homeowner’s permission to film broadcasts on the same porch, so you may hear them if you tune in. At other times, the homeowners or friends they’ve let use the house stop by. It’s surreal yet oddly comforting to hear the homey noises of people, a pet parkeet (?), and wild chickens outside while towering, terrifying yet magnificent lava fountains boom and chuff.
As for the big picture, we’re starting to settle into a routine with Kilauea’s ongoing double eruption:
We don’t know if crater has ejected more “ballistics” (flying rocks) since USGS scientists aren’t risking personnel by entering the possible “flying rocks” zone. Right now they’re working from a temporary base of operations in Hilo.
Hawaii Volcanoes National Park remains closed, not only to keep public out of range of flying rocks, but because of earthquake damage to trails and some park structures. These need to be assessed/repaired.
Park Rangers have set up in Hilo Bayfront to educate public about this historic eruption.
Oh look, another hazard from lava entering ocean: WATERSPOUTS.
And even when fissures don’t spout lava, they can still be dangerous:
Mick Kalber’s daily helicopter flyover includes some intense views of the rivers of lava heading into the ocean, and the big complex of fountains— 20? 22? we’re starting to lose track— that have dominated the Lava Livestream With Rooster for the last several days.
The USGS thermal scan is very informative, too: an infrared satellite detects heat sources (the whiter the image, the hotter it is), and USGS then overlays it on a daylight satellite image of same area. Result, accurate map of where the main flows are, even when they crust over so the lava inside is hidden:
Below the cut: a digest of the day’s eruption news, USGS updates (summarized), and striking social media images and video clips like this:
There’s two lava livestreams on Youtube this morning, same location, Honolulu CivilBeat mostly focusing on Fissure 20, ~1000 yards away. WXchasing moving camera more often [ETA: WX stream now archived]. HCB said Fissure 17 (3/5 a mile away) has built up a cinder cone 300 feet tall.
Last night, Fissure 20’s lava flow crossed Highway 137 and reached the ocean at 11PM, leaving some Puna residents with one escape route. Filed under “things I didn’t know,” Civil Defense warns of “Laze,” a spray of hot steam, hydrochloric acid, and “fine glass particles” when lava hits seawater.
Also filed under “things I didn’t know”: “Methane gas, produced as lava buries vegetation, can migrate in subsurface voids and explode when heated.” (USGS)
