- Current Update, last updated May 24, 2015 07:26 :
Activity Summary: Seismicity rates are currently normal beneath Kīlauea's summit and minor inflationary tilt has been observed starting early on May 24. At the East Rift Zone eruption site, surface flows continue to be active within about 8.6 km (5.3 mi) of Puʻu ʻŌʻō.
Summit Observations: Seismicity rates beneath Kīlauea's summit, upper East Rift Zone and Southwest Rift Zone were at normal, background levels during the past day. The summit tiltmeter network recorded deflationary tilt of the typical Halemaʻumaʻu source throughout the day on May 23, but is currently recording inflationary tilt, beginning just after midnight on May 24. Sulfur dioxide emission rates ranged between 3,800-8,500 tonnes/day for the week ending May 22.
Puʻu ʻŌʻō Observations: The tiltmeter on the north flank of Puʻu ʻŌʻō continues to show no significant tilt, and seismicity rates have been normal. The sulfur dioxide emission rate from all East Rift Zone vents was about 360 tonnes/day when last measured on May 19, 2015.
June 27th Lava Flow Observations: Webcam images and satellite imagery continue to show surface flow activity from several breakouts in an area northeast Puʻu ʻŌʻō. All surface flows are occurring within 8.6 km (5.3 mi) of 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.
