- Current Update, last updated Mar 30, 2015 07:57 :
Three areas of breakouts in the upslope portion of the June 27th flow field in Kīlauea's East Rift Zone continue to be active, all are within 6 km (4 mi) of Puʻu ʻŌʻō. The Alert level was reduced to WATCH on 03/25/15 owing to the decrease in immediate threat during the past several weeks. Kīlauea continues to host a lava lake at its summit.
June 27th Lava Flow Observations: Webcams showed overnight that three areas of breakouts continued to be active in the upslope portion of the June 27th flow field located to the northeast of Puʻu ʻŌʻō: the northern flank of Puʻu ʻŌʻō (Feb. 21 breakout), an area near Puʻu Kahauale’a, and an area 5-6 km (3-4 mi) northeast of Puʻu ʻŌʻō. Last Tuesday's HVO overflight showed that the farthest northeast breakout area was continuing to burn forest.
Puʻu ʻŌʻō Observations: The tiltmeter on the north flank of Puʻu ʻŌʻō continues to show no significant tilt. The sulfur dioxide emission rate from all East Rift Zone vents was about 400 tonnes/day when last measured on March 20.
Summit Observations: Tiltmeters at Kīlauea's summit recorded no significant tilt during the past day. The summit lava lake level has been steady for the last several days, at about 35-40 m (115-130 ft) below the rim of the Overlook crater. Summit tremor has been steady and somewhat elevated during the past several days as well. Sulfur dioxide emission rates averaged 4700 - 6300 tonnes/day for the week ending March 24.
- 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.
