Hawaii Volcano National Park - Current Update


Saturday, December 16, 2017, 9:04 AM HST (Saturday, December 16, 2017, 19:04 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: Kīlauea Volcano continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow is still producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The surface of the lava lake at Kīlauea's summit was measured at 44 m (143 ft) below the floor of Halemaʻumaʻu crater yesterday and has decreased since that time. There have been no significant changes in ground deformation or seismicity rates across the volcano.

Summit Observations: The lava lake surface was measured at 44 m (143 ft) below the rim of the Overlook Vent yesterday morning. Summit tiltmeters have continued to record deflationary tilt since that time. Summit sulfur dioxide emission rates remain high. Seismicity rates were at normal, background 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. Glow has been persistent at long-term sources within the crater and from a small lava pond on the west side of the crater. The tiltmeter on Puʻu ʻŌʻō cone recorded deflationary tilt 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. Based on overnight web camera images, surface lava flow activity persists on the upper portion of the flow field, on the pali and in scattered areas along the coastal plain. A new breakout came over the pali Monday morning and continues. These lava flows pose no threat to nearby communities at this time. A plume from the Kamokuna ocean entry area was not seen in webcam views over the past 24 hours. The webcam views are available at: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Ocean Entry Hazards: 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 a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.
