Lower East Rift Zone eruption continues unabated

View of Fissure 8 and channel during the morning overflight on July 7.

Lava entering the ocean as seen through steam and rain early this morning.

Fissure 8 continues to erupt lava steadily into the perched channel leading northeastward from the vent. Disruptions to the mid-channel occurred yesterday afternoon producing localized overflows along the margins of the flow field, mostly atop earlier lavas. A significant overflow north of the cinder quarry advancing yesterday and last night towards Cinder Rd. has stalled. An overflow lobe moving around the west side of Kapoho Cone remains active this morning and small brushfires are reported along the margins. Downstream, lava appears to be reoccupying the channel leading to the ocean entry were multiple fingers of lava are active. The southern margin of the ocean entry shows little sign of movement.

Yesterday's channel disruption and overflows were caused by blockages that developed along the channel. Additional blockages and resulting overflows are likely to occur as long as the activity continues.

Fissure 22 continues to exhibit weak spattering. No other fissures are active.

Pele's hair and other lightweight volcanic glass fragments from the lava fountain at Fissure 8 continue to fall downwind of the fissure, dusting the ground within a few hundred meters (yards) of the vent. High 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.

Near the Kapoho Crater, in the area called Four Corners, the lava channel makes a 90-degree bend. After lava exits the bend, it makes a short drop to form a lavafall. A side channel makes a short surface diversion before rejoining the existing channel.

Vigorous lava eruption continues from lower east rift zone of Kilauea

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.


Photo from 7AM helicopter overflight, hovering offshore and looking up the flowfront. 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.

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.
Summit plume at 8:40AM HST on June 3. A slight mist in the air softens the look of the plume, which is predominantly white steam with very minor amounts of ash.

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.

Immediate evacuation ordered as advancing lava threatens shut down of Highway 132

Lava flow near Highway 132
Fast moving lava approaching Highway 132 at Lava Tree State Park to Four Corners prompts more evacuations in Leilani estate in Puna, Big Island of Hawaii. If the Highway is completely shut down, Beach road will be the only escape route left for residents in lower Puna.

The Hawaiian Volcano Observatory reports an additional lava flow has crossed Pohoiki Road south of the Highway 132 junction.  



Late Monday afternoon, Fissure 8 erupted into volcanic fountain reaching a height of 100-150 feet, spawning a fast-moving flow that moved north along Luana Street. According to Hawaiian legend, this has led to Pele's hair being transported downwind with some strands falling in Pahoa. The United States Geological Survey (USGS) has urged the residents to minimize exposure to Pele's hair (volcanic glass), which can cause skin and eye irritation similar to volcanic ash.



Here is a YouTube video in which the Hawaii Volcanoes National Park Ranger, Adrian Boone explains the origin of "Pele's Hair" at Kilauea Volcano.

Since last reported 16, 18, 22,13, and 20 were active, with a flow moving south from Fissures 16/18.
An ash eruption at Halemaumau crater last night produced ash plume 15,000 feet in the air.  Light winds are blowing toward the northwest and ash fall may affect the Volcano and Pahala areas. Earthquakes continue in the summit region as the area is adjusting to the flow of magma.
