HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, February 19, 2018, 7:17 AM HST (Monday, February 19, 2018, 17:17 UTC)


KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: No significant change. Kīlauea Volcano continues to erupt at the summit and the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow activity persists on the upper portion of the flow field and on Pulama pali. Lava is not entering the ocean at this time. These lava flows pose no threat to nearby communities. The lava lake surface is approximately 34 m (112 ft.) below the floor of Halemaʻumaʻu. Low rates of ground deformation and seismicity continue across the volcano.

Summit Observations: Summit tiltmeters are recording inflationary tilt at Kīlauea. The lava lake surface is approximately 34 m (112 ft.) below the rim of the Overlook Vent, based on webcam images. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Summit sulfur dioxide emission rates remain high. Current webcam views are here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater. There were no significant changes in seismicity over the past 24 hours. The tiltmeter has shown a deflationary trend over the past day. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active, but no lava is flowing into the ocean. Based on overnight web camera images, surface lava flow activity persists on the upper portion of the flow field and on Pulama pali. None of these flows poses any threat to nearby communities at this time. A distant webcam view of the coastal plain is available here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html. Maps of the lava flow field can be found here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html

Ocean Entry Hazards: Even though the Kamokuna lava delta is not currently active, it remains hazardous to visitors. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to the lava delta exposes you to flying debris from sudden explosions should the lava delta begin to collapse. Though inactive at present, the lava delta remains unstable because it is built on unconsolidated lava fragments on the steep submarine slope of Kīlauea. This loose material can easily be eroded away by surf and shoreline currents, causing the delta to become unsupported and slide into the sea. In several instances, such collapses have also incorporated parts of the older sea cliff. Should lava again resume entry into the ocean, the interaction of lava with seawater creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: No significant change. Kīlauea Volcano continues to erupt at the summit and the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow remains active on the upper portion of the flow field and on Pulama pali. Lava is not entering the ocean at this time. These lava flows pose no threat to nearby communities at this time. The lava lake surface this morning was 34.5 m (113 ft) below the floor of Halemaʻumaʻu. Low rates of ground deformation and seismicity continue across the volcano.

Summit Observations: Summit tiltmeters have shown little change over the past 24 hours. This morning, the lava lake surface was measured by laser rangefinder to be 34.5 m (113 ft) below the floor of Halemaʻumaʻu. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Summit sulfur dioxide emission rates remain high. Current webcam views are here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō Observations: Webcam images have been hampered by rainy weather overnight, but clear views show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater. There were no significant changes in seismicity over the past 24 hours. The Puʻu ʻŌʻō tiltmeter has shown little significant change over the past day. The general inflationary trend over the past few days is likely due to heavy rainfall. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active, but no lava is flowing into the ocean.

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, February 13, 2018, 8:22 AM HST (Tuesday, February 13, 2018, 18:22 UTC)


KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: No significant change. Kīlauea continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. This morning, the summit lava lake was 39 m (128 ft) below the floor of Halemaʻumaʻu crater. Surface lava flow activity continues on the upper portion of the flow field near Puʻu ʻŌʻō, on the pali, and near the base of the pali. Lava is not entering the ocean at this time, and active flows currently pose no threat to nearby communities.

Summit Observations: Summit tiltmeters began recording inflationary tilt last night. When measured this morning, the summit lava lake was 39 m (128 ft) below the floor of Halemaʻumaʻu crater, slightly shallower than yesterday morning. Sulfur dioxide emission rates remain high. Seismicity is at normal levels, with tremor fluctuations related to the vigor of lava lake spattering. Webcam views of the lava lake can be found here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō Observations: The tiltmeter on Puʻu ʻŌʻō cone has shown little significant change over the past day. Webcam views overnight show continued glow from a small lava pond on the west side of the crater. The sulfur dioxide emission rate from the East Rift Zone vents remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active, but no lava is flowing into the ocean. Based on web cam views and field reports from over the weekend, surface lava flow activity continues on the upper portion of the flow field near Puʻu ʻŌʻō, on the pali, and near the base of the pali. These lava flows pose no threat to nearby communities at this time. A distant webcam view of the coastal plain is available here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html. Maps of the lava flow field can be found here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html

Ocean Entry Hazards: Even though the Kamokuna lava delta is not currently active, it remains hazardous to visitors. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to the lava delta exposes you to flying debris from sudden explosions should the lava delta begin to collapse. Though inactive at present, the lava delta remains unstable because it is built on unconsolidated lava fragments on the steep submarine slope of Kīlauea. This loose material can easily be eroded away by surf and shoreline currents, causing the delta to become unsupported and slide into the sea. In several instances, such collapses have also incorporated parts of the older sea cliff. Should lava again resume entry into the ocean, the interaction of lava with seawater creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Activity Summary: No significant change. Kīlauea continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. Friday morning the level of the summit lava lake was about 37 m (121 ft) below the floor of Halemaʻumaʻu crater and the level has dropped overnight. The episode 61g lava flow is producing scattered surface flow activity on the pali, at the base of the pali, and the upper flow field. Lava is not entering the ocean at this time, and active flows currently pose no threat to nearby communities.

Summit Observations: Summit tiltmeters recorded sharp deflationary tilt yesterday. Early this morning, inflationary tilt resumed. A brief increase in seismicity below the summit occurred around midnight, just before inflationary tilt returned. Friday morning, the level of the lava lake was about 37 m (121 ft) below the floor of Halemaʻumaʻu crater; in concert with yesterday's deflation, the lake level has dropped. Sulfur dioxide emission rates remain high. Seismicity is at normal levels, with tremor fluctuations related to the vigor of lava lake spattering. Webcam views of the lava lake can be found at https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō Observations: The tiltmeter on Puʻu ʻŌʻō cone recorded slight deflationary tilt during the past day. Intermittent webcam views overnight show that glow persists from a small lava pond on the west side of the crater. The sulfur dioxide emission rate from the East Rift Zone vents remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active, but no lava is flowing into the ocean. Based on web cam views, surface lava flow activity continues on the upper portion of the flow field near Puʻu ʻŌʻō, on the pali, and near the base of the pali.
