Activity Summary: Inflationary tilt continued at Kīlauea's summit over the past day, and was accompanied by a modest increase in lava lake level. The East Rift Zone lava flow remains active northeast of Puʻu ʻŌʻō, but has not advanced significantly and poses no threat to nearby communities. Low levels of seismic activity continue across the volcano.
Summit Observations: Data from Kīlauea's summit tiltmeters showed that inflationary tilt continued during the past day. The lava lake displayed a corresponding steady rise within the vent as well. Seismicity continues at background levels. Summit sulfur dioxide emission rates ranged from 2,600 to 5,500 metric tons/day for the week ending July 28.
Puʻu ʻŌʻō Observations: There was no obvious change in activity at Puʻu ʻŌʻō, which hosts several incandescent, outgassing crater vents. Low levels of background seismicity continue. The sulfur dioxide emission rate from all East Rift Zone vents was about 500 tonnes/day when measurements were last possible on July 23, 2015.
'June 27th Lava Flow' Observations: Webcam and satellite views show continued activity on the flow field. Active breakouts were scattered across a broad area extending from about 4 to 8 km (2.5–5 mi) northeast of Puʻu ʻŌʻō. The most distant breakouts are evident by the smoke plumes produced where they are creeping into the forest and burning vegetation along the edge of the flow field.
- 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.
