Activity Summary: The summit of Kīlauea Volcano continues to inflate, and the summit lava lake rose to within about 2 m (~7 ft) of the Overlook crater rim. Seismicity beneath the summit and the upper East Rift Zone is elevated. At the East Rift Zone eruption site, widespread breakouts are active within about 8 km (5 mi) of Puʻu ʻŌʻō.
Summit Observations: Kīlauea's summit continued to inflate slowly over the past day, accumulating a total of about 7.5 microradians since inflation started on Tuesday, April 21. The summit lava lake rose slightly since yesterday and is about 2 m (7 ft) below the Overlook crater rim (i.e., the floor of Halemaʻumaʻu Crater) this morning. Seismic activity beneath Kilauea's summit and upper East Rift Zone remains elevated. Sulfur dioxide emission rates averaged 3000-5200 tonnes/day for the week ending April 21.
Puʻu ʻŌʻō Observations: The tiltmeter on the north flank of Puʻu ʻŌʻō recorded no significant change over the past day, but there has been net inflation over the past week. Otherwise, there were no noticeable changes at Puʻu ʻŌʻō. The sulfur dioxide emission rate from all East Rift Zone vents was about 850 tonnes/day when last measured on April 21, 2015.
June 27th Lava Flow Observations: Webcam views of flow field incandescence indicate that surface flows remain active northeast of Puʻu ʻŌʻō. The most distant activity was burning forest about 8 km (5 mi) northeast of the crater when mapped on April 23.
- 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.
