HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Saturday, January 20, 2018, 8:18 AM HST (Saturday, January 20, 2018, 18:18 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. The episode 61g lava flow is producing scattered surface flow activity and lava is not entering the ocean. Lava flows pose no threat to nearby communities at this time. Friday morning, a rockfall into the lava lake at Kīlauea's summit produced an explosion of debris that blanketed an area around the southeast rim of Halemaʻumaʻu crater. Prior to the explosion, the lava lake was 39 m (128 ft) below the floor of Halemaʻumaʻu crater and it has changed little overnight.

Summit Observations: Summit tiltmeters continue to record deflationary tilt. Early Friday morning, a rockfall from the wall of Halemaʻumaʻu crater plunged into the lava lake producing a short-lived explosion of spatter and wallrock that blanketed an area around the former visitor overlook. Debris fell as far as the Halemaʻumaʻu parking lot. Before the rockfall, the lava lake was 39 m (128 ft) below the floor of Halemaʻumaʻu crater and the level has changed little overnight. 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. A short video of yesterday's event can be found here: https://volcanoes.usgs.gov/observatories/hvo/multimedia_uploads/multimediaFile-1846.mp4

Puʻu ʻŌʻō Observations: Tiltmeters at Puʻu ʻŌʻō recorded no significant change during the past day. 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. Surface lava flow activity continues on the upper portion of the flow field near Puʻu ʻŌʻō , on the pali, and in scattered areas along the coastal plain. These lava flows pose no threat to nearby communities at this time. A distant webcam view of the coastal plain is available at: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.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: Kīlauea continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow is producing scattered surface flow activity and lava is not entering the ocean. Active lava flows pose no threat to nearby communities at this time. This morning, the surface of the lava lake at Kīlauea's summit is 39 m (128 ft) below the floor of Halemaʻumaʻu crater, 8 m (26 ft) lower than yesterday morning. There have been no significant changes in seismicity, deformation, or gas release across the volcano in the past 24 hours. Earlier this morning two earthquakes of magnitude 2.4 and 2.5 occurred on the lower East Rift Zone near Leilani Estates.

Summit Observations: Summit tiltmeters continued to record a deflationary trend over the past day and the lake level lowered about 8 m (26 ft). This morning the lake was measured at 39 m (128 ft) below the floor of Halemaʻumaʻu crater. Sulfur dioxide emission rates remain high. Seismicity is at normal levels, with tremor fluctuations related to 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: Tiltmeters at Puʻu ʻŌʻō recorded very little change in tilt during 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. Surface lava flow activity persists on the upper portion of the flow field, on the pali, and in scattered areas along the coastal plain. These lava flows pose no threat to nearby communities at this time. A distant webcam view of the coastal plain is available at: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

U.S. Geological Survey
Sunday, January 14, 2018, 9:34 AM HST (Sunday, January 14, 2018, 19:34 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. Lava is not entering the ocean at this time. Kīlauea continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow is producing scattered surface flow activity. Active lava flows pose no threat to nearby communities at this time. This morning, the surface of the lava lake at the Kīlauea summit was roughly 30 m (98 ft) below the floor of Halemaʻumaʻu. Deflation began this morning, and there have been no significant changes in seismicity or gas release across the volcano.

Summit Observations: Summit tiltmeters recorded the onset of deflationary tilt at about 6 am today, and the lake level has changed only slightly. This morning the lake was roughly 30 m (98 ft) below the floor of Halemaʻumaʻu. Sulfur dioxide emission rates remain high. Seismicity is at normal levels, with tremor fluctuations related to 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: No significant changes are evident at Puʻu ʻŌʻō. 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. Surface lava flow activity persists on the upper portion of the flow field, on the pali, and in scattered areas along the coastal plain. These lava flows pose no threat to nearby communities at this time. A distant webcam view of the coastal plain is available at: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Ocean Entry Hazards: Even though the lava delta is not currently active, the ocean entry 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 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. 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.
