- Current Update, last updated Oct 6, 2015 08:33 :
Activity Summary: Eruptions continue without significant change at Kīlauea Volcano's summit and in its east rift zone at Puʻu ʻŌʻō. Seismicity, deformation, and outgassing continue at low background rates across the volcano. There is no lava flow threat to nearby communities.
Summit Observations: The lava lake in the Overlook Vent continues to circulate and spatter. Small fluctuations in lava lake level are visible via the Webcams. Monday morning's measurement of the depth to the lava lake surface was 57.5 m (about 189 feet) below the current vent rim. Low levels of seismic activity continue with episodic fluctuation of volcanic tremor amplitudes. Summit sulfur dioxide emission rates ranged from 1,500 to 4,300 metric tons per day during the 2-week period ending September 30.
Puʻu ʻŌʻō Observations: Eruptive activity continues at Puʻu ʻŌʻō with no significant changes or events. Sulfur dioxide emission rate from all East Rift Zone vents was about 400 metric tons per day when measurements were last possible on September 14, 2015.
June 27th Lava Flow Observations: The 'June 27th' lava flow continues with scattered surface flow activity. The lava flow is not threatening any communities. Satellite images of the flow field show lava breakouts between 3 km and 7 km (1.9 and 4.3 mi) northeast of Puʻu ʻŌʻō. The overall level of surface activity appears to have declined slightly compared to the past few months.
- 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.
