Activity Summary: Kīlauea Volcano continues to erupt at its summit and East Rift Zone. At the summit, the lava lake continues to circulate and occasionally spatter, producing a gas plume during the day and glow at night. At the East Rift Zone, surface flows are still active within about 8 km (5 mi) northeast of Puʻu ʻŌʻō.
Summit Observations: Summit tiltmeters recorded the start of slow inflationary tilt yesterday afternoon. In concert with the tilt, the level of the lava lake rose a bit and is 39 m (128 ft) below the rim of the Overlook crater this morning. Seismicity rates beneath Kīlauea's summit continued within background values, with bursts of seismic tremor associated with periods of vigorous spattering of the lava lake. Sulfur dioxide emission rates ranged between 2,100-2,700 tonnes/day for the week ending June 30.
Puʻu ʻŌʻō Observations: There have not been any significant changes at Puʻu ʻŌʻō. Seismicity rates are at background levels. Webcams show multiple incandescent outgassing vents within the crater. The sulfur dioxide emission rate from all East Rift Zone vents was about 700 tonnes/day when last measured on June 19, 2015.
June 27th Lava Flow Observations: Webcam images indicate that active lava breakouts continue within an area extending about 8 km (5 mi) northeast Puʻu ʻŌʻō.
- 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.
