Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED

Please see this new section of the HVO web site for information on the ongoing activity at Kilauea Volcano: https://volcanoes.usgs.gov/observatories/hvo/activity_2018.html

LOWER EAST RIFT ZONE

Moderate-level eruption of lava continues from multiple points along the northeast end of the active fissure system. Residents in lower Puna should remain informed and heed Hawaii County Civil Defense closures, warnings, and messages (http://www.hawaiicounty.gov/active-alerts)

Spattering continues from Fissures 6 and 17 with significant lava flows being erupted from Fissures 20. Two of these lava flows from Fissure 20 reached the ocean along the southeast Puna coast overnight; however, a crack opened under the east lava channel early this morning diverting the lava from the channel into underground voids. This may cause changes downslope in the channel system and the ocean entry.

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

For the most recent map showing the locations of activity, please see https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html These maps are updated as often as possible but may not reflect the most recent changes.

Volcanic gas emissions have tripled as a result of the voluminous eruptions from Fissure 20 so SO2 concentrations are likely elevated to higher levels throughout the area downwind of the vents. Moderate trade winds today means that areas downwind of Kilauea gas emission sources may experience varying levels of vog. For forecast information, please see: http://mkwc.ifa.hawaii.edu/vmap/hysplit/

For other information about vog, please see:https://vog.ivhhn.org/

This eruption is still evolving and additional outbreaks of lava are possible. Ground deformation continues and seismicity remains elevated in the area.

Future outbreaks could occur both uprift (southwest) and downrift (northeast) of the existing fissures, or, existing fissures can be reactivated. Communities downslope of these fissures could be at risk from lava inundation. Activity can change rapidly.

Conditions around the erupting fissures can change very quickly. Residents in lower Puna should remain informed and heed Hawaii County Civil Defense closures, warnings, and messages (http://www.hawaiicounty.gov/active-alerts).


KILAUEA SUMMIT

Over the past day, two explosive eruption of ash have occurred. Several smaller ash emissions have also taken place. Additional explosions possible at any time.

Seismic levels, which abruptly decreased after explosive eruptions on Saturday afternoon and Sunday noon, are again slowly increasing.

At this time, based on HVO web cameras, a robust plume of gas and steam is billowing out of the Overlook vent and drifting generally southwest.

At any time, activity may again become more explosive, increasing the intensity of ash production and producing ballistic projectiles very near the vent. Communities downwind should be prepared for ashfall as long as this activity continues.

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.

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.

KILAUEA SUMMIT

Multiple small eruptions of ash occurred over the past day, all ejecting ash to under 10,000 ft above sea level. Additional explosions possible at any time.

Maybe too early to tell, but is there any scope for the Kilauea eruption to affect short-medium term weather locally and /or globally?

Very unlikely. This would need to be VEI 6 (+) and ejecting the plume well into the stratosphere. Kilauea is not likely to meet those criteria.

Kīlauea Volcano Lower East Rift Zone

Eruption of lava and ground cracking continues in the area of Leilani Estates and Lanipuna Gardens subdivision.

The middle portion of the fissure system continues to produce the most robust eruptive activity in the Lower East Rift Zone. The most active fissures have been 22,19, 6, 5, and 23. A faint glow was seen from Fissure 9, but no flows, and methane was observed burning in road cracks overnight. The ocean entry remains active and is producing occasional small explosions. Observers noted the height of the perched lava pond / channel had reached 11 meters / 36 feet above the ground level.

Lava is probably still entering the ocean. Although we can't get visual confirmation until after dawn, instrumental signals are consistent with continuing ocean entry activity.

Volcanic gas emissions remain very high from these fissure eruptions.

For recent maps of activity, see: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html

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

Magma continues to be supplied to the lower East Rift Zone. Elevated earthquake activity continues, but earthquake locations have not moved farther downrift in the past couple of days, and there were only a few earthquakes located yesterday in the rift zone.

USGS/HVO continues to monitor the lower East Rift Zone activity 24/7 in coordination with Hawaii County Civil Defense, with geologists onsite to track ongoing and new fissure activity and the advance of lava flows.

Kīlauea Volcano Summit

Small ash emissions from the Overlook crater occurred frequently throughout the night. Moderate trade winds were blowing to the southwest and ashfall may be noticed in downwind locations. Earthquakes in the summit area continue at a moderate rate, as does deflation of the summit region.

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 if such an explosion occur, please consult the Ash3D model output here: https://volcanoes.usgs.gov/observatories/hvo/activity_2018.html

Nope far too small. It's been in eurption since 1983 this is just another variation of the same eruption. Who much longer it will go on who knows but there have been longer eruptions from the volcano. Locally it';s having an effect due to VOG and Laze from gases and interaction with the sea.

Fissure 22 continues to erupt lava that is flowing southeast to the coast and the lava ocean entry. Fountains at Fissures 6 and 13 feed lava into a channel that reaches the coast forming a second ocean entry.

Fissures 7 and 21 are feeding a perched lava pond and pāhoehoe flow that has advanced northeastward covering most of the area between Kaupili and Mohala Streets. The flow front has become an 'A'ā flow and is advancing slowly toward Pahoa Pohoiki Road. The latest observations indicate the flow front is about 150 yards from the road. On the west side of Fissure 7 a perched pāhoehoe flow (near Makamae St) broke out around 04:00am feeding short flows to the west. Overnight, flaming and vigorous spatter was observed from a cone on Fissure 8, while Fissure 17 was the source of multiple booming gas emissions. Sensors in the LERZ indicated that the lava ocean entries remained active 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.

Volcanic gas emissions remain very high from the fissure eruptions.

Magma continues to be supplied to the lower East Rift Zone. Earthquake activity continues, but 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

There were three explosions from Overlook Crater (00:42am, 01:44am, and 05:00am) that produced ash clouds to between 10,000 and 11,000 feet above sea level. The National Weather Service Nexrad radar indicated that the clouds quickly dispersed. Several smaller explosions occurred over the course of the night. Moderate trade winds were blowing to the southwest and light ash fall likely occurred in downwind locations.

Earthquakes in the summit region continued at a moderate rate overnight. The earthquakes and ash explosions are occurring 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 if such an explosion occur, please consult the Ash3D model output here: https://volcanoes.usgs.gov/observatories/hvo/activity_2018.html

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.

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.

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.

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. This morning, lava activity at both vents has diminished and the ocean entries are weaker than yesterday. Fissure 6 is no longer active. Fissure 21 has been intermittently active.

Fissure 7 activity is very active, producing a large spatter rampart over 100 feet tall from fountains reaching 150-200 feet. The fountains fed two perched channels--the north channel fed a lava flow that advanced toward pad E of the PGV property and the south channel a flow that was advancing to the southeast along the west border of the fissure 22 flow.

The Fissure 7 north channel fed a flow that advanced into PGV property and approached pad E before it stalled this morning; however, the flow was refreshed by lava from the vent and, about noon, started to advance again covering a portion of pad E and also producing a narrow flow to the north of pad E. These flows continue to be active as of this posting.

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

Kīlauea Volcano Summit

Ash continued to erupt intermittently from the Overlook crater, within Halemaʻumaʻu crater, at the Kīlauea summit, the largest occurred around noon producing an ash column to nearly 10,000 ft. 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.

Thanks...ever hopeful of seeing something of that ilk in my lifetime...if I recall correctly Mr St Helens famous eruption in 1980 did have some impact..(?)

Pinatubo's in 1991 was assessed to have brought down global temperatures by 0.5 Deg C from 1991 to 1993 or so.  That was a VEI 6 and about 10 times the size of Mt. St. Helens in terms of ejecta, ejecting its ash up to 34km (21 miles) high at its peak, well into the stratosphere. Pretty substantial. Would be nice if nature could display without threatening peoples' lives, homes, livelihoods and also local ecosystems, however, events of this magnitude are always going to leave casualties. Impressive but sadly catastrophic too.

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.

Fissures 7 and 8 remain the most active eruptive centers of the system and have been feeding lava flows that have advanced northeast onto PGV property. At about 7:00 PM HST, a fast-moving lava flow broke from this area and advanced rapidly to the north and west through the eastern portion of Leilani Estates. Several residents were evacuated in advance of the dangerous and fast-moving flows.

Activity at Fissure 22 has waned, and Fissure 13 is the dominant source of lava entering the ocean, which is occurring at three minor entry points. Fountaining is occurring at Fissure 8.

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 weakening, and widespread vog is expected on the Island of Hawaii on Monday.

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.

KÄ«lauea Volcano Summit

Ash continued to erupt intermittently from the vent within Halemaʻumaʻu crater, at Kīlauea's summit, but no significant ash columns have been produced since noon on Sunday. Observations from the ground, by UAV, 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, but are diminishing in intensity as wind patterns shift late Sunday and early Monday. This may bring ashfall to 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 ashfall downwind are possible at any time. Volcanic gas emissions at the summit remain high.

The last eruptions to have a noticeable effect in Europe were Krakatoa, Laki Eruption,  Tambora.

Tambora was a vei 7 another one like that would probably cause world wide famine of unthinkable proportions. Laki would cause Europe and North America severe problems.

They would probably lead to political unrest and massive changes in society.

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.

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.

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. If a forecast shift in wind direction occurs today, widespread vog could occur on the Island of Hawaii.
