Activity Summary: Kīlauea Volcano continues to host a lava lake at its summit and erupt from its East Rift Zone. The East Rift Zone lava flow is active northeast of Puʻu ʻŌʻō; flow field breakouts remain within about 6.1 km (4 mi) of the vent. Lava continues to erupt for a second day onto the floor of Pu`u `O`o crater. Seismicity and deformation are within normal levels throughout the volcano.
Summit Observations: Activity at the summit continues with the lava lake height ranging from 40 - 50 m (135 - 165 ft) below the floor of Halema`uma`u. Seismicity levels are at normal background rates with another Very Long Period (VLP) earthquake at the summit at 2:34am HST. Nearby tiltmeters transitioned from inflationary to deflationary tilt at about 9:30pm HST. Summit sulfur dioxide emission rates averaged around 4,000 metric tons/day for the past week.
Puʻu ʻŌʻō Observations: Thermal webcams show lava continuing to erupt onto the floor of Pu`u `O`o crater. A small amount of lava began to erupt from a second vent within the crater this morning, and flows from both vents are confined to the crater. Small amounts of inflationary tilt continue to be recorded by a tiltmeter near Pu`u `O`o’s summit, while seismic activity is normal. The sulfur dioxide emission rate from all East Rift Zone vents was about 460 metric tons/day when measurements were last possible on November 5, 2015.
June 27th Lava Flow Observations: Webcam images continue to show scattered activity on the 'June 27th' flow field. All active flows are between around 1.9 and 6.1 km (1 and 4 mi) of Puʻu ʻŌʻō. The lava flow is not currently threatening any communities.
- Volcanic History Overview: Kilauea volcano is one of the most active and best studied volcanoes in the world and is renowned for the accessability of her eruptions. Throughout her history, Kilauea has erupted from three main areas, its summit and two rift zones. Kilauea currently has a summit caldera, but it may not always have been evident. Most eruptions are relatively gentle, sending lava flows downslope from fountains a few meters to a few hundred meters high. Over and over again these eruptions occur, gradually building up the volcano and giving it a gentle, shield-like form. Every few decades to centuries, however, powerful explosions spread ejecta across the landscape. Such explosions can be lethal, as the one in 1790 that killed scores of people in a war party near the summit of Kilauea. Such explosions can take place from either the summit or the upper rift zones. Kilauea has erupted more than 60 times in the past 150 years. The current eruption began in 1983.
