Brantley showed a cutaway diagram of the East Rift Zone of Kīlauea Volcano. The illustration shows the plumbing of the volcano, with an orange pipe - a conduit from Kīlauea summit directly to lower Puna that is sending down the lava.
Before the recent changes at Kīlauea, Puʻu ʻŌʻō Crater served to temper the activity at the summit, letting out steam and letting out lava. On about May 1, Brantley explained, the summit of the volcano began subsiding, as a reflection of magma now moving out of the summit reservoir, into the rift zone, and further down into the lower East Rift Zone. "So, in a sense there is an open conduit from the summit to the lower east rift zone," he said.
For the 35 years or so that Puʻu ʻŌʻō was active, there was a kind of balance between the summit reservoir and the location or elevation where Puʻu ʻŌʻō erupted. There was sort of a symbiotic relationship with the summit and Puʻu ʻŌʻō. Now, that new vent system is located almost at sea level, said Brantley. "So the whole system has to adjust to some sort of new balance. And until that balance is reached or something else changes, we expect magma to continue moving from the summit reservoir into the rift zone and further down into the lower east rift zone.
"That suggests that we are in it for the long haul. We don't know how long this eruptions is going to last. But for now it looks like it's just going to continue and we take it day by day."

THE FISSURE FROM KĪLAUEA VOLCANO, which is sending S02 into Kaʻū, became more active this week. USGS scientist Steve Brantley told a community meeting in Pāhoa yesterday: "That's pretty obvious to everybody here because of the additional lava that's on the surface... with that much more lava on the surface, it's able to pour across the ground and it had reached the ocean. And depending on which vent is active and producing most of the flow, the lava flows will create a new path, they've spread apart, they've merged and then they've spread apart again.
On Monday, there were two ocean entries. Later in the day there was only one. All day Tuesday, there was only one." Per the USGS website, today at noon there was still only one ocean entry.
Brantley said it is hard and confusing to track all the vents, since there are so many. The most productive vent is number 22, generating most of the lava and created the lava flow that winds down to the ocean.
Tuesday, Fissures 6 and 15, which are close together, started to head toward the south.
Fissure 17 is the most downrift part of the intrusion of magma just below ground. He said that the area is stable and that there is no evidence that the magma has moved further downrift and forced the rift apart. ther fissures became active again this week in the middle of Leilani Estates.
Brantley talked about the changing chemistry of the lava that's erupting from the East Rift Zone.
"One thing that's clear is that more magma's coming to the surface now than earlier in the eruption sequence." He pointed to a map with all of the fissures represented by dots (see map, above).
The green dots represent the type of lava that was probably stored in the rift zone for decades before it came out and erupted at the surface. "That lava presumably was forced up to the surface as magma moved down the East Rift Zone, pushed its way into the Lower East Rift Zone, and forced that magma to the surface."
Brantley pointed to fissure 16, and said that the fissures, indicated by red dots in the above map, started to show lava with a difference: a mixture of the old magma and the newer lava that originated higher in the rift zone, from Puʻu ʻŌʻō and perhaps the summit at Halemaʻumaʻu. "Now we are seeing the fresh stuff coming up to the surface." The new lava is hotter, less viscous, more fluid and voluminous. Where the lava flows depends on the locations of the fissures.
So far, most of the lava has flowed away from Puna Geothermal plant, away from Highway 132 to the south, and into the ocean, he said.

On Saturday, an ash explosion reached 10,000
feet. Last night a little after 10 p.m. ,
another explosive eruption sent ash 8,000 to 9,000 feet up. There have been
multiple ash eruptions every day since the 15th, and the ash drifts with the wind. Currently,
most ashfall from these events is reaching Pāhala and places further southwest of the
summit.

KAʻŪ RESIDENTS WITNESSING ASHFALL ARE URGED TO REPORT IT. USGS scientists want to know when ashfall arrives, and if predicted ashfall does not arrive. USGS also asks for residents to collect ash to send to USGS for study. Get the details at http://hawaiiash.science/ashreport.php
The explosive eruptions sending the ash Kaʻū's way have also widened Halemaʻumaʻu crater. According to USGS reports, the first ash plume rose from the crater May 9 from possible rockfall. Last Thursday, an eruption threw ash some 30,000 feet above sea level, apparently enlarging Halemaʻumaʻu crater from 12 to 34 acres. See an illustration here: https://volcanoes.usgs.gov/observatories/hvo/maps_uploads/image-438.gif.

Scientists
predict that the eruptions could last for weeks, or longer, before Kīlauea Volcano possibly
settles down. Risks are breathing the ash and, near the caldera, rocks that
fly out of the crater. Boulders as large as small cars could be thrown a half
mile from the crater vent, scientists reason. In 1924, violent explosions
lasted two weeks.
SO2 REACHED A READING OF UNHEALTHY for sensitive groups in Pāhala from 12:15 a.m. through
6:15 a.m. , and again from 7:30 a.m. through 8:45
a.m. Ocean View experienced short spikes of unhealthy
for sensitive groups at 2:30 a.m. and
7:30 a.m. Both monitoring locations
showed mostly good levels otherwise. Kona has shown good since midnight .
Air Quality Index
last reported levels at 1 p.m. Pāhala
was good at 34. Both Ocean View – at 87 – and Kona – at 97 – were shown as
moderate.

ASH MASKS WILL BE DISTRIBUTED AT OCEAN VIEW COMMUNITY CENTER, Nāʻālehu Community Center, Pāhala Community Center, Cooper Center, and Shipman Gym in Keaʻau. Distribution will be "while supplies last" today, Thursday, and Friday from 3:30 p.m. to 7:30 p.m., and Saturday, May 26, from 9 a.m. to 1 p.m. Each person may receive up to three masks.
Ron Gall, President of Ocean View Community Association, and Hawaiʻi County Civil Defense remind residents that ash masks do not provide protection from S02 and other gasses. The masks do protect against ash and other particulates, which are moving through Kaʻū from Kīlauea Volcano as winds blow this way.

CRUISE SHIPS WILL SOON RETURN TO HAWAI`I ISLAND, stated Ross Birch of Hawaiʻi Island Visitor Bureau today. Birch said cruise ships will return to Kona on May 30, and Hilo on June 6. The cancellation of cruise ships since the beginning of ashfall from Kīlauea has cost the island economy more than one million dollars, according to the bureau.

WAIKAPUNA: A WAHI PANA (TREASURED PLACE) OF KAʻŪ Coffee Talk
at Kahuku Unit of Hawaiʻi Volcanoes National Park, Friday, May 25, 9:30 a.m. to
11 a.m.
The release from
the park says: Wahi pana? Waikapuna is certainly that. It was an ancient
fishing village and an important historic and cultural resource of Kaʻū. Located
makai of Nāʻālehu, it has one of the largest native coastal dune systems,
a large sandy bay, tidepools, onshore and below sea level springs, and sea
caves which are homes to colonies of nesting seabirds. It houses significant
sections of the original Ala Kahakai and numerous archeological sites.
Presenter
Keoni Keanu Fox, a lineal descendant of Waikapuna and a representative of the
Ala Kahakai Trail Association, will talk about the cultural, historical and
environmental treasures of this special place.
Coffee Talk at
Kahuku “is an opportunity to get to know your Park and your neighbors,” and
join in an informal conversation on a wide variety of topics. It is
presented on the last Friday of the month at 9:30
AM . Kaʻū coffee, tea and pastries will be available for purchase.
Kahuku Unit is located south of the 70.5 mile marker on the mauka side of Hwy.
11, and is remaining open with extended days during the partial park closure:
Wed through Sun, 9 a.m. to 3 p.m.
