Lava from fissure 8 meets ocean at the Kapoho bay

Overflight photograph at approximately 6:13 a.m. HST shows the lava flow originating from Fissure 8 (not visible in photograph) entering Kapoho Bay. The ocean entry was reported to have occurred by 10:30 p.m. on the night of June 3, 2018.

The lava from fissure 8 entered the ocean at  Kapoho Bay at about 10:30 PM HST on June 3 generating a laze plume that is blowing inland but dissipating quickly. As of today morning, the lava is also constructing a delta in Kapoho Bay extending a few hundred yards into the bay.

The lava flow front is half a mile wide. A sluggish lava flow was observed in the vicinity of fissure 18 and rest of the fissures are all inactive.

Volcanic gas emissions remain very high from the fissure eruptions and also at the summit. Trade wind conditions are bringing vog to the south and west sides of the Island of Hawaii. Afternoon easterly winds may bring vog to communities in the Volcano area.

Inward slumping of the rim and walls of the walls of Halema`uma`u continues in response to persistent subsidence.

The USGS is predicting an increased earthquake activity in the coming days.

Some of the photos from USGS update today:

What a difference four days makes! These thermal images of fissure 8 fountains erupting on Kīlauea's lower East Rift Zone show a few things: 1) The lava fountains have gained height—with the tallest one growing from 150 ft to over 250 ft. 2) A pu‘u (cone) has built up downwind. 3) The amount of material wafting downwind is greater. Scientifically, we know the fountain temperatures are reaching up to about 2040 degrees F (1115 C). The composition of the lava erupted has high MgO (magnesium oxide) values, which comes from olivine crystals that are being pulled from deep in the rift zone.

Overnight (June 1-2), fissure 8 lava fountains decreased to heights of about 50 m (164 feet). The moon can be seen in the upper left.

This video was taken on the June 3 7AM HST helicopter overflight, hovering offshore and looking up the flow front. Nearly all of the front was active and advancing; advance rates were estimated at an average of 250 feet/hour (76 m/hr), and as of 7AM the flow was 500 yards (457 m) from the ocean.

Mount Kilauea continues to erupt lava one month after it all started on May 3, 2018.  Fissure 8 is persistently fountaining since a week delivering lava northeast along Highway 132 to the Kapoho area. The lava stream was about 430 yards from the ocean at the Kapoho Bay between Kapoho Beach Road and Kapoho Kai Drive.

All other fissures are silent now, although Fissure 9 is steaming heavily.

Pele's hair and other lightweight volcanic glass from high fountaining of Fissure 8 are falling downwind of the fissure and accumulating on the ground within Leilani Estates.

Earthquake activity at the summit was high overnight, and it is possible that a small explosion, much like those that have occurred during the past two weeks, will take place in the next day. Ash emissions are low as revealed by webcam views this morning. Volcanic gas emissions at the summit remain high.

Here are some of the latest photos by United States Geological Survey 

As fissure 8 lava flowed into Green Lake, the lake water boiled away, sending a white plume high into the sky—visible from afar between around 11:30 a.m. and 1:30 p.m. HST. This aerial photo, taken a couple of hours later by the Hawai‘i County Fire Department, shows still-steaming lava within Green Lake, located near the intersection of Highways 132 and 137.

What’s going on with the Kilauea Volcano?

Fissure 8 was active throughout Tuesday and into Wednesday morning sending fountains of lava at a sustained height of 200 feet with multiple secondary fountains that reached 60-feet.

This increased activity continued feeding a lava flow that moved towards Highway 132 at the rate of approximately 600 yards/hour. The flow moved north of Highway 132 in the vicinity of Noni Farms and Halekamahina roads, advancing along the steepest descent path that could take the flow to the Four Corners area.

Adding on to yesterday’s eruption, flow from fissure 18 increased further moving downslope toward Highway 137 at rates of less than 100 yards per hour. Overnight, sporadic bursts of activity were also observed from Fissures 7 and 15.

Pele's hair and other lightweight volcanic glass from high fountaining of Fissure 8 are falling to the west of the fissure and continue accumulating on the ground within Leilani Estates. Winds may waft lighter particles to greater distances. Residents are urged to minimize exposure to these volcanic particles, which can cause skin and eye irritation similar to volcanic ash.

On the other hand, Kīlauea Volcano Summit saw relatively few activities on Tuesday and into Wednesday. Ash continued to erupt intermittently from the vent within Halemaʻumaʻu crater, but vertically high ash plumes were not recorded.

USGS warns that explosive events that could produce minor amounts of ash fall downwind are possible at any time. Volcanic gas emissions at the summit remain high and will combine with wind conditions to produce widespread vog across the Island of Hawaii on Wednesday.

Fissure 8 reactivated to create 200-feet high lava fountains

Lava eruption and gas emission continue unabated from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens. Today, fissure 8 remained very active, at times fountaining to the height of 200-feet. The lava flowed atop the Fissure 8 ʻaʻā flow that was active Sunday night/Monday morning to cross the highway 132 just before 2 pm HST Tuesday.

This voluminous activity of fissure 8 has produced Pele's hair and other lightweight volcanic glass that is being transported downwind and falling to the west of the fissure.

Tuesday also saw weak activity at fissure 18 and 19, but fissure 18 eruption has created a lava channel which has advanced 1.6 miles towards the coast.

Ash and gas eruption are continued from the summit, while ocean entry of lava has diminished significantly as viewed from this overflight photo.

Here is a video of fissure 8 reactivation

Three short videos of Kilauea from helicopter overflights

Compilation of three short videos from helicopter overflights of the fissure complex, in Kīlauea Volcano's lower East Rift Zone on May 22, 2018. Fissure 22 is the dominant fissure, with lava fountaining to 50 m (about 160 ft) or more in height.

A moderate-level eruption of lava continues from multiple points along the central and northeast end of the active fissure system.

Fissure 6 through 22 are erupting lava fountains. The fountains from Fissure 22 feed a single lava channel that reaches the coast just north of MacKenzie State Park. The actual point of entry has been shifting to the west today. Spattering continues from Fissures 5, 6, and 19 that fed a lava flow to the south that is now stalled and a smaller flow to the north along and south of Pohoiki Rd. Fissures 17 continue weak spattering.

Finally, the erupting and overflowing lava meets the ocean to create more health hazards

White plumes of acid and fine shards of glass fill the Hawaiian sky over the east coast of Big Island as Lava from active fissures near the Leilani Estates subdivision gushes into the Pacific Ocean at 2 points along the coastline. The lava has completed nearly 4-mile crawl to meet the ocean, creating dangerous living conditions for residents in Kamaili, Seaview, and Malama Ki neighborhoods.

It was about 11 P.M. on Saturday night when the emergency management officials first confirmed that lava from fissure 20 has reached the ocean.

The 20^th fissure opened on May 15, 2018, in Kilauea's eastern rift zone and has been spewing lava since then. The lava flow suddenly increased beginning Friday, May 18 when the fissure 16 and fissure 20 merged resulting in a continuous line of splatter and fountaining.

The merger happened less than a mile from the coast and created a  lava river that slowly meandered southward between Pohoiki and Opihikao Rds on its way towards the ocean.

Meanwhile, a crack has opened under the east lava channel early Sunday morning diverting the lava from the channel into underground voids. This may stall the lava flow into the ocean.

The sudden increase in the volume of lava eruption from fissure 20 has tripled the volcanic gas emissions and SO2 concentration in the area downwind of the vents.

Seismic levels which abruptly decreased after explosive eruptions on Saturday afternoon and Sunday noon, are again slowly increasing along with continued deformation at the Kilauea summit.

A small explosion occurred at 12:55 AM at Halema'uma'u crater at Kilauea's summit. It produced an ash plume that reached about 7,000 ft and was carried by the wind to the southwest.

As the flow pours into the water and creates new land, officials are issuing new warnings about the threat for laze, the steam-like substance that rises from the ocean as the lava comes into contact with ocean water. Laze is a mix of hydrochloric acid, steam, and fine glass particles.

Laze plume travels with the wind and can cause lung damage, and eye and skin irritation.

Meanwhile, The United States Geological Survey has just updated about fissure 22 putting on a show, with lava fountains as high as 150 feet in the air.
