- Current Update, last updated Sep 4, 2015 07:09 :
Activity Summary: The lava lake at Kīlauea's summit remains active. Summit tiltmeters recorded slow inflationary tilt overnight. The East Rift Zone lava flow northeast of Puʻu ʻŌʻō remains active within 8 km (5 mi) of the vent and does not currently pose a threat to communities. Normal levels of seismic activity continue across the volcano.
Summit Observations: The lava lake level fluctuated but remained at about 47 m (154 ft) below the floor of Halemaʻumaʻu as measured yesterday morning. Seismic tremor associated with spattering on the surface of the lava lake continued. Tiltmeters at Kīlauea's summit recorded the switch to slow inflationary tilt at about 2 pm yesterday. Trade winds have resumed blowing the gas plume to the southwest into the Ka‘ū desert this morning. Summit sulfur dioxide emission rates ranged from 1,700 to 2,700 metric tons per day for the week ending September 1.
Puʻu ʻŌʻō Observations: Normal activity (continuous gas release and glow at night) continued from vents within the crater. The sulfur dioxide emission rate from all East Rift Zone vents was about 390 metric tons per day when measurements were last possible on August 13, 2015.
June 27th Lava Flow Observations:Clear webcam views yesterday and overnight showed continued scattered activity on the flow field northeast of Puʻu ʻŌʻō. Lava breakouts are active only within about 8 km (5 mi) of Puʻu ʻŌʻō and are not threatening any structures. Some breakouts are marked by smoke plumes where lava is creeping into the forest.
- 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.
