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 entering the ocean at Kamokuna and producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The height of the lava lake at Kīlauea's summit changed little over the past day and was last measured at about 40 m (131 ft) below the Overlook crater rim. Low rates of ground deformation and seismic activity persist across the volcano.

Summit Observations: The lava lake at Kīlauea's summit continues to be active; its height has not changed much since it was last measured at 40 m (131 ft) below the rim of the Overlook crater on Monday afternoon. No significant change in ground tilt was recorded by summit tiltmeters in the past 24 hours. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 2,500 and 5,400 metric tons/day over the past week. Seismicity rates were at normal, background levels, with tremor fluctuations related to lava lake spattering.

Webcam views of the Halemaʻumaʻu lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Puʻu ʻŌʻō Observations: In the past day, seismic activity has continued at normal, background rates and no significant ground tilt was recorded by a nearby tiltmeter. Webcams show persistent glow from long-term sources within the crater and from a small lava pond on the west side of the crater. The sulfur dioxide emission rates from the East Rift Zone vents have been steady over the past several months, and remain significantly lower than the summit emissions.

Lava Flow Observations: Lava from the episode 61g flow continues to enter the ocean at Kamokuna. Webcam views show persistent surface flow activity on the upper portion of the flow field and on the coastal plain, as well as renewed surface flow activity on the pali. At the ocean entry, intermittent lava flows over the cliff and onto the lava delta ("lavafalls") continue. Surface cracks on the lava delta that had been covered over, are propagating to the surface and beginning to be visible again. The episode 61g flows do not pose a threat to nearby communities at this time.

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.
