HAWAIIAN VOLCANO OBSERVATORY STATUS REPORT

From U.S. Geological Survey Saturday, June 2, 2018, 7:39 PM HST

KILAUEA VOLCANO (VNUM #332010)

19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)

Current Volcano Alert Level: WARNING

Current Aviation Color Code: RED

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. 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. Trade wind conditions are bringing vog to the south and west sides of the Island of Hawaii.

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.

Kīlauea Volcano Summit

Earthquake activity at the summit overnight was low. Ash emissions are low as revealed by webcam views this morning. Small explosive events could produce minor amounts of ash fall downwind at any time. Volcanic gas emissions at the summit remain high.

HTH June 1, 2018: Lava within half-mile of “Four Corners” in Kapoho “Advancing 100 yds per hour”

East Rift Zone Eruption: Fri 6/1/18 12PM - Update 3

This is a Civil Defense Message for Friday, June 1 at 12:00 noon.

Hawaiian Volcano Observatory reports that vigorous lava eruptions continue on the east rift of Kilauea. Fissure 8 is very active and producing a large flow. As of 11:00 a.m. this morning, the flow front was still above the Four Corners area. At the present rate, it is possible the lava flow may cross Government Beach Road near Four Corners within hours. 

Due to the rapid lava flow, the following policies are in effect for the Four Corners area (the intersection of Highway 132 and 137):

  • Residents in Vacationland, Kapoho Beach Lots and in areas near Highway 137 are advised to complete evacuation or risk isolation.
  • Traffic is flowing both ways to allow evacuation.
  • Shelters at the Kea’au Community Center and the Sure Foundation Church have been relocated to the Kea’au Armory, in the back of the Herbert Shipman Park, off of Highway 11. The shelter at Pahoa Community Center remains open. The shelters are pet friendly.

Leilani Estate east of Pomaikai Street is under mandatory evacuation order. All persons must clear the area by now. 

The Pahoa Post Office will be open from 10:00 a.m. through 2:00 p.m. to distribute mail and packages to evacuees and residents experiencing interruptions in mail delivery service. 

For your safety, heed warnings from Civil Defense officials and stay alert. 

We are on watch 24-hours a day for your safety.

This is your Hawai‘i County Civil Defense Agency.

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.

Overnight, fountaining at Fissure 8 continued to feed a channelized lava flow to the northeast along Highway 132. Small overflows from the channel are occurring along its length, including in a few places near the intersection of Highway 132 and Pohoiki road. The advance rates of the distal part of the flow overnight were low as lava ponded in a flat area. In the last few hours, advance rates have picked up to about 100 yards/hour. As of 6:30 AM HST, the lava flow front was 0.84 miles above Four Corners (the intersection of Highway 132 and 137). Minor advancement occurred on other branches of the Fissure 8 lava flow.

Fissure 18 and its associated flow are weakly active with widely scattered lava breakouts. Fissure 22 is 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 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.

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

The lava flow from Fissure 8 reached Pohoiki Rd. this morning and stalled as the Fissure's activity abruptly diminished. A few fissures reactivated briefly during the day. As of the 1 pm overflight, Fissure 8, 18, 20, 22, 6/13, and 7/21 reactivated with Fissure 7/21 having the highest fountains. The reactivated fissures have not yet erupted enough lava to reach the coast so the two ocean entry sites were relatively inactive. Only a minor ooze of residual lava was entering the ocean from the Eastern channel.

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

Overnight, field crews confirmed that the fast-moving flow that broke out at about 7 PM HST Sunday night originated from Fissure 8. The fissure fed a channelized flow that moved north along the margin of the existing flow before turning east and crossing out of Leilani Estates near the intersection of Kahukai and Hookupu streets. As of 8 AM HST Monday morning it had started to cross Pohoiki Road, but the advance rate slowed from hundreds of meters (yards) per hour on Sunday night to a few meters (yards) per hour this morning.

Fissures 6/13 are inactive, and Fissure 9 is reactivated but erupting small amounts of lava that are pooling nearby. Fissure 7/21 are no longer active and lava flows from that fissure have largely stalled on PGV property.

Kīlauea Volcano Summit

Ash continued to erupt intermittently from the vent within Halemaʻumaʻu crater, at Kīlauea's summit. A brief emission event at about 4:35 AM HST this morning sent ash to about 10,000 feet above sea level but was not associated with a significant tilt offset. A similar event at about 6:30 AM sent ash to approximately 12,000 feet above sea level. Earthquakes are currently occurring at high rates in the summit area. Observations from the ground, by UAS, and by satellite during the past week have documented retreat of the summit vent walls due to collapse of the steep conduit and rim. Trade winds are causing ash fall to the southwest. If a forecast shift in wind direction occurs today, ash fall may occur in communities around the summit area.

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.

HTH May 27, 2018 7pm:  Civil Defense has ordered Leilani Estates residents on Nohea and Luana streets between Leilani Avenue and Kahukai, and on Kupono Street between Malama Street and Leilani Avenue to evacuate immediately because of fast moving lava from fissure No. 7 ... 

Civil Defense reports that lava from fissures No. 7 and 21 have covered a geothermal production well at Puna Geothermal Venture....  

That well, KS-6, along with a second well about 100 yards away have been “successfully plugged” and “are stable and secured, and are being monitored,” according to the agency’s 6 p.m. message.

“Also due to preventative measures, neither well is expected to release any hydrogen sulfide,” the message said.

(Trnaslation: Decades of Punatic anti-Geothermal hysteria have just been proven false--but we don't want to call attention to that.)

Kīlauea Volcano Lower East Rift Zone

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

Fissures 22 and 13 continue to feed lava flows extending south to the lava ocean entry. Signals recorded on stations in the LERZ indicate that the lava ocean entry remained active overnight.

Fissure 21 is feeding an 'a'ā flow that has continued to advance to the northeast on PGV property. However, the rate of advance has slowed overnight coincident with an observed decline in the vigor of fountaining at Fissure 21. Fissure 7 activity has increased overnight, producing a large spatter rampart over 100 feet tall from fountains reaching 150-200 feet. The fountains fed a perched pāhoehoe flow 20-40 feet thick, and ultimately a flow that had turned south toward the coast last night.

Large cracks were observed overnight on Kupono St. about 360 yards north of Malama St, near Fissure 9. Fissure 8 had three vents active overnight that were spattering and flaming, and have doubled in size over the past 24 hours. Fissure 6 was inactive overnight.

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 expected to diminish Sunday evening, which could expand the area impacted by vog.

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 Overlook crater at the Kīlauea summit. Observations from the ground and by UAV during the past week have documented retreat of the Overlook crater wall due to collapse of the steep enclosing walls and rim. Trade winds took the ash clouds primarily to the southwest. Trade winds are expected to diminish Sunday evening and communities around the summit area could see ashfall.

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 ashfall downwind are possible at any time. Volcanic gas emissions at the summit remain high.

HAWAIIAN VOLCANO OBSERVATORY STATUS REPORT

From U.S. Geological Survey Saturday, May 26, 2018, 5:20 PM HST

KILAUEA VOLCANO (VNUM #332010)

19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)

Current Volcano Alert Level: WARNING

Current Aviation Color Code: RED

Kīlauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone fissure system in the area of Leilani Estates and Lanipuna Gardens. As of this morning, almost 2400 acres have been covered by new lava.

Fissures 22, 6, and 13 are feeding lava flows moving southeast to the coast southwest of Pohoiki. At midday today, two ocean entries were active. Over the past 24 hours, channels feeding these ocean entries have diminished somewhat in vigor, however the laze plume generated remains significant.

Fissures 7 and 21 are feeding an 'a'ā flow that has advanced to the northeast and this afternoon crossed Pahoa Pohoiki Road onto PGV property.

A current 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 expected to diminish Sunday evening and the area impacted by vog could expand.

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 Overlook crater at the Kīlauea summit. Observations from the ground and by UAV during the past week have documented retreat of the Overlook crater wall due to collapse of the steep enclosing walls and rim.

During the most energetic event of the day, ash from Overlook crater rose as 12-13,000 feet above sea level based on National Weather Service radar. Trade winds took the ash clouds primarily to the southwest. Trade winds are expected to diminish Sunday evening and communities around the summit area could see ashfall.

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 ashfall downwind are possible at any time. Volcanic gas emissions at the summit remain high.

For forecasts of where ash would fall under forecast wind conditons, please consult the Ash3D model output here: https://volcanoes.usgs.gov/observatories/hvo/activity_2018.html

Information on ash hazards and how to prepare for ashfall maybe found here: http://www.ivhhn.org/information#ash
