Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Late this afternoon, vigorous fountaining resumed at Fissure 8, spawning a fast moving flow that moved north along Luana Street. As of 10:00 PM HST the flow front had reached within 300 yards of Kahukai street. The flow is traveling an estimated 20 yards per hour to the northeast. An overflight early this evening showed that Fissures 16, 18, 22,13, and 20 were active, with a flow moving south from Fissures 16/18.

Pele's hair from vigorous fountaining of Fissure 8 is being transported downwind, and there are reports of some strands falling in Pahoa. Residents are urged to minimize exposure to Pele's hair (volcanic glass), which can cause skin and eye irritation similar to volcanic ash.

The most recent map of lava flows can be found here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html

HVO field crews are on site tracking the fountains, lava flows, and spattering from multiple fissures as conditions allow and reporting information to Hawaii County Civil Defense. Crews are also checking on the status of ground cracks on Highway 130.

Volcanic gas emissions remain very high from the fissure eruptions. Trade winds are forecast to return in the coming days, meaning vog will impact the southern and western sides of the island.

Magma continues to be supplied to the lower East Rift Zone. Earthquake locations have not moved farther downrift in the past few days and the number of located earthquakes remains low.

Additional ground cracking and outbreaks of lava in the area of the active fissures are possible. Residents downslope of the region of fissures should heed all Hawaii County Civil Defense messages and warnings.

USGS/HVO continues to monitor the lower East Rift Zone activity 24/7 in coordination with Hawaii County Civil Defense.

Kīlauea Volcano Summit

Ash continued to erupt intermittently from the vent within Halemaʻumaʻu crater, at Kīlauea's summit. Winds have weakened and shifted in direction so that ash fall could occur in communities around the summit area.

A magnitude 4.1 earthquake occurred at 5:39 PM HST on the Koa'e fault zone south of the caldera. Earthquakes in the summit region continue as the summit area subsides and adjusts to the withdrawal of magma.

Additional explosive events that could produce minor amounts of ash fall downwind are possible at any time. Volcanic gas emissions at the summit remain high.

KÄ«lauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fissure 8 remained very active today fountaining to heights of 200 feet at times and feeding a lava flow that advanced atop the Fissure 8 Ê»aÊ»Ä flow that was active Sunday night/Monday morning. The first lobe of this flow crossed highway 132 just before 2 pm HST Tuesday. Lava continues to advance toward the northeast

Visual observations early Tuesday afternoon also confirmed continued weak activity at Fissures 18 and 19. Fissure 18 has produced channelized flows which have advanced 1.6 mi toward the coast.

Pele's hair and and other lightweight volcanic glass from high fountaining of Fissure 8 are being transported downwind and falling to the west of the fissure. On Monday night, there were reports of Pele's hair falling in PÄhoa.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fissure 8 maintained high fountains throughout Tuesday night and into Wednesday morning, with sustained heights exceeding 200 feet and the presence of multiple secondary fountains that reached to 60 feet. This fountaining continued to feed a lava flow that moved downslope along Highway 132. Advance rates accelerated late Tuesday and early Wednesday, reaching approximately 600 yards/hour. The flow moved north of Highway 132 in the vicinity of Noni Farms and Halekamahina roads, advancing along a steepest descent path that could take the flow to the Four Corners area.

The Fissure 18 flow also remained active, 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 and other lightweight volcanic glass from high fountaining of Fissure 8 are falling to the west of the fissure and accumulating on the ground within Leilani Estates. Winds my 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.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fissure 8 continued to produce persistent fountains that reached heights up to 260 feet. A small spatter cone is forming on the downwind side of the fountain and is approximately 100 feet high. The fountains are feeding flow activity to the northeast, and minor overflows from the Fissure 8 channel are occurring along its length. One overflow covered the remaining northern part of Makamae Street in Leilani Estates. This overflow crossed Kahukai street, filling in a low area between Makamae and Luana streets. The front of the Fissure 8 flow near Noni Farms road advanced at rates up to 100 yards/hour. At 12:30 PM HST, the flow front was 1.9 miles from the Four Corners area.

High eruption rates from Fissure 8 have led to the formation of a leveed channel along the western edge of the lava flow. Failure of flow levees could result in rapid advance of flows. Flow margins are extremely hazardous and should not be approached.

Fissure 18 feeds the upper part of a lava flow that extends to 1.5 mi from Highway 137; the lower portion of the fissure 18 lava flow stalled about 0.5 mi from the highway. Fissure 2 is weakly active and is pooling lava around the vent.

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. 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.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fountaining at Fissure 8 is reaching 180 - 220 feet in height and continues to feed a channelized lava flow to the northeast along Highway 132 and down into the Four Corners region (at the intersection of Highways 132 and 137). Small overflows from the channel are occurring along its length, including in a few places near the intersection of Highway 132 and Pohoiki road. As of 9:50 PM HST the flow front was approximately 0.28 miles from the intersection. The more western branches of the Fissure 8 flow either stalled or advanced only short distances.

Fissure 18 appears to be crusted over or inactive. The flows that had been moving toward Highway 137 are either inactive or moving very slowly. Fissure 22 appears to be inactive.

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. 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.

Kīlauea Volcano Summit

A small explosion occurred form the summit at 1:39 PM HST. Ash emissions are overall decreased, however, possibly reflecting the accumulation of rubble at the base of the growing summit crater. Earthquake activity remains high due to ongoing summit deflation. Additional explosive events that could produce minor amounts of ash fall downwind are possible at any time. Volcanic gas emissions at the summit remain high.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fountaining at Fissure 8 continued unabated during the day, feeding a channelized lava flow to the northeast along Highway 132 that has crossed Highway 137 at the intersection of the two highways at 9:30 AM this morning. The flow continued advancing into Kapoho Crater and Kapoho Beach Lots. At 10 AM, lava entered Green Lake within Kapoho Crater producing a large steam plume. By 1:30 PM the steam plume had ceased and by 3 pm, a Hawaii County Fire Department overflight reported that lava had filled the lake and apparently evaporated all the water. Other branches of the Fissure 8 lava flow were inactive.

The only other lava flow noted by the morning overflight was at Fissure 16, which was weakly active.

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.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fountaining at Fissure 8 continued feeding a robust lava channel to northeast along Highway 132 to the ocean entry in Kapoho bay. As of late afternoon the lava entry had built a delta extending approximately 700 yards into the bay. A laze plume is blowing inland from the ocean entry but dissipating quickly. The lava flow front is about 600 yds wide. A lava breakout was also occurring upslope of the Kapoho cone cinder pit but stalled about 300 yards southeast of the intersection of Railroad Avenue and Cinder Road.

Sluggish lava flows are present in the vicinity of Fissure 18; all other fissures are inactive.

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.

Volcanic gas emissions remain very high from the fissure eruptions. 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.

The ocean entry is a hazardous area. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris from sudden explosive interaction between lava and water. Also, the lava delta is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. In several instances, such collapses have also incorporated parts of the older sea cliff. Additionally, the interaction of lava with the ocean creates "laze", a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Magma continues to be supplied to the lower East Rift Zone. Earthquake locations have not moved farther downrift in the past few days and the number of located earthquakes remains low. Seismicity remains relatively low with numerous small magnitude earthquakes and low amplitude background tremor.

Kīlauea Volcano Summit

Earthquake activity at the summit has been low after the explosive eruption yesterday, but is slowly increasing. Inward slumping of the rim and walls of Halema`uma`u continues in response to persistent subsidence. We expect that earthquake rates may increase in the coming hours to days and culminate in another small explosion, following the pattern of the past few weeks.

Over the last week, sulfur dioxide passively degassing from the volcano's summit has decreased, but emission rates remain high enough to impact air quality in downwind regions. Additional bursts of gas released with intermittent explosive activity are also transported downwind and may temporarily affect air quality as well.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Lava fountaining at Fissure 8 is continuing with fountain heights reported at 150-180 feet. This eruptive activity continues to feed a channel transporting lava to the northeast along Highway 132 and east to the ocean entry in Kapoho Bay area. Minor breakouts along the channelized flow field continue to occur but all have been very small and have stagnated before travelling any significant distance. HVO's mid-day overflight showed the fissure 8 flow has completely filled Kapoho Bay and formed a lava delta extending 0.8 miles out from the former coastline. The northernmost lobe of the Fissure 8 flow, in the Noni Farms Road area, is advancing very slowly to the northeast. No other fissure vents showed significant activity at this time.

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.

Kīlauea Volcano Summit

Earthquake activity dropped after this morning's small explosion and is now slowly rising following the pattern of previous events of this type. Monitoring data show that subsidence at the summit crater continues. The mid-day observation flight showed continued Inward slumping of the rim and walls of Halema`uma`u in response to subsidence at the summit.

Locally felt earthquakes are expected to continue and further ash explosions are likely.

Over the last week, sulfur dioxide passively degassing from the volcano's summit has decreased, but emission rates remain high enough to impact air quality in downwind regions. Additional bursts of gas released with intermittent explosive activity are also transported downwind and may temporarily affect air quality as well.

This morning, lava fountaining at Fissure 8 continued to reach heights of 150-180 feet, feeding a stable channel to the east to the ocean entry in the Kapoho Bay area. Lava is entering the ocean in the Vacationland subdivision. Vacationland has been completely covered by lava, and overnight the flow expanded north by 100 m within Kapoho Beach Lots. The lava delta that formed at Kapoho Bay extended slightly overnight.

The northern lobe of the Fissure 8 flow shows no signs of activity this morning, and there is only wispy smoke at the flow front. No other fissures are active.

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. 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.

The most recent map of lava flows can be found at https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html

HVO field crews are on site tracking the fountains, lava flows, and spattering from multiple fissures as conditions allow and are reporting information to Hawaii County Civil Defense.

Volcanic gas emissions remain very high from the fissure eruptions. For the next few days wind conditions may bring vog not only to the south and west sides of the Island of Hawaii, but also the island's interior.

The ocean entry is a hazardous area. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris from sudden explosive interaction between lava and water. Also, the lava delta is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. In several instances, such collapses have also incorporated parts of the older sea cliff. Additionally, the interaction of lava with the ocean creates "laze", a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Magma continues to be supplied to the lower East Rift Zone. Earthquake locations have not moved farther downrift in the past few days and the number of located earthquakes remains low. Seismicity remains relatively low with numerous small magnitude earthquakes and low amplitude background tremor.

Additional ground cracking and outbreaks of lava in the area of the active fissures are possible. Residents downslope of the region of fissures should heed all Hawaii County Civil Defense messages and warnings.

USGS/HVO continues to monitor the lower East Rift Zone activity 24/7 in coordination with Hawaii County Civil Defense.

KÄ«lauea Volcano Summit

Earthquake activity is increasing after Tuesday morning's small explosion, with ten M3+ earthquakes since 5 am in the KÄ«lauea summit area. This pattern suggests that more felt earthquakes and a small explosion are likely within the next few hours. Monitoring data indicate that subsidence at the summit and inward slumping of the rim and walls of Halema`uma`u continues.

Over the last week, sulfur dioxide emissions from the volcano's summit have decreased, but emission rates remain high enough to impact air quality in downwind regions. Additional bursts of gas released with intermittent explosive activity are also transported downwind and may temporarily affect air quality as well.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates.

Lava fountaining at Fissure 8 fluctuated with heights varying between 190 and 215 feet. This activity is feeding a lava channel flowing east to the ocean entry in the Kapoho Bay area. The noon overflight found that the delta is about 1.2 mi wide in the Vacationland/Waopae area and observed the flow was expanding northward through Kapoho Beachlots. A large area of upwelling offshore suggests the presence of lava flowing on the ocean floor in that area.

No other fissures are active.

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. 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.

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates.

Lava fountaining from Fissure 8 reached about 200 feet in height. Today's morning and noon overflights reported no significant changes in the fountain nor in the channels carrying lava to the ocean. Mid-morning, lava started to slowly spill over the channel levees in the vicinity of Pohoiki road but most of the lava did not extend far enough to reach ground not already covered by lava. By early afternoon, lava was again confined to the flow channel.

Minor lava activity at Fissures 16/18 continued.

Kīlauea Volcano Lower East Rift Zone

Eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates.

Lava fountain heights of 130-140 ft were observed overnight within the growing cone of cinder and spatter at Fissure 8. Fountaining at Fissure 8 continues to feed the fast moving channelized flow that is entering the ocean at Kapoho. This morning's overflight of the LERZ observed a towering steam plume from a focused ocean entry point. Offshore of the entries, areas of upwelling have become more dispersed than when initially sighted. The sporadic spattering from Fissures 16/18 of the last several days has diminished, although the fissures continued to glow noticeably overnight.

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

Kīlauea Volcano Lower East Rift Zone

The eruption of lava continues from the lower East Rift Zone (LERZ) in Leilani Estates with little change over the past few days.

Lava fountains reaching heights of 53 m (174 ft) were observed at Fissure 8 in the late afternoon. Lava from Fissure 8 continues to flow through the well-established channel to the ocean at Kapoho, with rare, small overflows of the channel levees. A laze plume at the ocean entry was blown onshore this afternoon, and areas of upwelling offshore were present throughout the day. Fissures 16 and 18 continue to ooze lava.

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..

Now this eruption could go on for ages if the supply of magma continues to match the output as it has done for a long time in this present eruption cycle. Of course the pathway to rift zone may become blocked then it's likely that the eruption could possible return to the previous location and the slumping at the Caldera ceases as Magma returns to support it.

The eruption in the lower East Rift Zone (LERZ) continues with no significant change during the past 24 hours.

Fountains from Fissure 8 spatter cone continue to supply lava to the open channel with only small, short-lived overflows. During an overflight early this morning, geologists observed incandescence from Fissure 22, but no associated spattering or flow. Lava is entering the sea this morning on the southern side of the entry area primarily through the open channel, but also along a 1-kilometer (0.6 mi) wide area. The entry areas are marked by billowing laze plumes.

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.

Kīlauea Volcano Summit

At 6:52 p.m. HST on June 22, after approximately 25 hours of elevated seismicity, a collapse explosion occurred at the summit producing an ash-poor steam plume that rose 500 ft above the ground surface (4,500 ft above sea level) before drifting to the SW. The energy released by the event was equivalent to a magnitude 5.3 earthquake. Seismicity dropped abruptly from a high of 40 earthquakes per hour (many in the magnitude 3 range) leading up to the collapse explosion to 10 or less earthquakes per hour afterwards. Overnight, seismicity gradually increased, reaching about 30 earthquakes per hour by daybreak. Inward slumping of the rim and walls of Halemaʻumaʻu continues in response to ongoing subsidence at the summit.
