Mel’s Note: The only good news I can report is that FEMA is providing some financial relief to homeowners who have had their places overrun by lava or those who have homes still standing but can’t access due to the active lava flow. Fissure 8 (Pu’u Leilani) is still erupting and sending lava to the ocean entry in Kapoho.

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

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

Lava fountains from Fissure 8 reached heights of 200 ft overnight. The cinder and spatter cone that is building around the fissure is now about 165 ft at its highest point. Lava is flowing through the well-established channel from fissure 8 to the ocean at Kapoho. Occasionally, lava spills over the channel levees. The ocean entry remained fairly broad with laze blown onshore. 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. 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.

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 Fissure 8 as conditions allow and are reporting information to Hawaii County Civil Defense. Observations are also collected on a daily basis from cracks in the area of Highway 130; no changes in temperature, crack width, or gas emissions have been noted for several days.

Volcanic gas emissions remain very high from Fissure 8 eruptions. Shifting wind conditions may bring VOG to the central, south, and western parts of the Island of Hawaii. VOG information can be found at https://vog.ivhhn.org/

The ocean entry is a hazardous area. 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. 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. Seismicity remains relatively low in the area with numerous small magnitude earthquakes and low amplitude background tremor. Higher amplitude tremor is occasionally being recorded on seismic stations close to the ocean entry.

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

Seismicity increased overnight, climbing to about 40 events per hour with up to 5 magnitude-3+ earthquakes per hour. Many of these earthquakes were felt in the Volcano area. Inward slumping of the rim and walls of Halema`uma`u continues in response to ongoing subsidence at the summit.

Sulfur dioxide emissions from the volcano's summit have dropped to levels that are about half those measured prior to the onset of the current episode of eruptive activity. This gas and minor amounts of ash are being transported downwind, with small bursts of ash and gas accompanying intermittent explosive activity.

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

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.

A line of closely spaced vents at Fissure 8 are continuing to erupt producing fountains reaching heights up to 160 feet, just higher than the spatter cone around them. This activity continues to feed the fast moving channelized flow that is entering the ocean at Kapoho. Weak spattering is continuing at Fissures 16/8 as has been noted for the last several days. This morning's overflight observed a small overflow of a minor pond on the east side of Fissure 8 that did not extend beyond earlier Fissure 8 lavas. Lava was entering the ocean over a broader length this morning with several minor incandescent points and small plumes and two larger entries and corresponding plumes. The upwelling areas were also more dispersed than yesterday.

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. 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.

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 Fissure 8 as conditions allow and are reporting information to Hawaii County Civil Defense. Observations are also collected on a daily basis from cracks in the area of Highway 130; no changes in temperature, crack width, or gas emissions have been noted for several days.

Volcanic gas emissions remain very high from Fissure 8 eruptions. Gas emissions have increased over the past two weeks. Trade wind conditions are expected to bring vog to the south and west sides of the Island of Hawaii. Vog information can be found athttps://vog.ivhhn.org/

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

At 1:52 AM HST, another small ash-poor explosion occurred at Kīlauea's summit. This event and many of its precursory earthquakes were widely felt in the Volcano area. Seismicity dropped following the event as it typically has with recent explosions. Inward slumping of the rim and walls of Halema`uma`u continues in response to ongoing subsidence at the summit.

Sulfur dioxide emissions from the volcano's summit have dropped to levels that are about half those measured prior to the onset of the current episode of eruptive activity. This gas and minor amounts of ash are being transported downwind, with small bursts of ash and gas accompanying intermittent explosive activity.

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.

The three closely spaced lava fountains at Fissure 8 are erupting with a slightly lower maximum heights of 115-130 feet. Lava continues to be fed into the channelized flow trending north and then east to a single ocean entry at Kapoho. Weak lava activity at Fissures 16/18 was observed last night. This morning's overflight confirms that fountaining continues at Fissure 8 and that its channel is nearly full with no spillovers. Minor steam explosions were observed at the ocean entry.

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. 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.

Observations are also collected on a daily basis from cracks in the area of Highway 130; no changes in temperature, crack width, or gas emissions have been noted for several days.

Volcanic gas emissions remain very high from Fissure 8 eruptions. Gas emissions were recently measured to be nearly twice the value of the past two weeks. Trade wind conditions are expected to bring vog to the south and west sides of the Island of Hawaii.

Kīlauea Volcano Summit

Overnight, there were two explosions at the volcano's summit. The first, smaller event occurred at 12:46 AM. Following this event, seismicity did not significantly drop off and a second explosion occurred at 4:43 AM. This event was larger than the first and was more typical of the size of events that have been occurring at the summit over the past week. Inward slumping of the rim and walls of Halema`uma`u continues in response to ongoing subsidence at the summit.

Sulfur dioxide emissions from the volcano's summit have dropped to levels that are about half those measured prior to the onset of the current episode of eruptive activity.
