- Current Update, last updated Feb 27, 2015 19:06 :
USGS Hawaiian Volcano Observatory (HVO) scientists conducted a helicopter overflight of the June 27th lava flow today and mapped its perimeter. At the time of the flight, scattered breakouts were observed upslope of the flow tip that had stopped advancing earlier this week, located from about 0.6 to 2.7 km (0.4 to 1.7 mi) upslope of the inactive tip. Small breakouts were also active west of Kaohe Homesteads. The breakout on the flank of Puʻu ʻŌʻō was active during the overflight, but had advanced only about 80-100 m (90-110 yd) since Monday, February 23. Two breakouts by Kahaualeʻa were also active today. The more northerly breakout was no longer spreading into the forest; surface flows were scattered within the margins of the flow. The northeasterly breakout advanced about 500 m (550 yd) since Monday, February 23, but its leading edge was not active today. HVO geologists were not able to make measurements of the cross-sectional area of the lava tube because of the active breakouts on the flank of Puʻu ʻŌʻō; the survey line was partially buried by these breakouts.

- 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.
