Activity Summary: Kīlauea Volcano continues to erupt at its summit and within its East Rift Zone. According to Civil Defense the front of the lava flow closest to Pāhoa advanced 9 m (10 yards) since yesterday afternoon. The flow continues to have surface breakouts behind the flow front as of this morning according to HVO webcams and Civil Defense.
June 27th Lava Flow Observations: Civil Defense reported this morning that the leading tip of the active flow advanced 9 m (10 yards) and widened to approximately 27 m (30 yards) since yesterday afternoon. The flow front is now 630 m (0.4 miles or 690 yards) from the Pāhoa Marketplace and 960 m (0.6 miles or 1050 yards) from the intersection of Highway 130 and Pāhoa Village Road. The flow remains active behind the front in several areas.
Puʻu ʻŌʻō Observations: No significant change in ground tilt has been observed in the past 24 hours and tilt remains flat. All other monitoring data indicate no significant changes at Puʻu ʻŌʻō. The most recent measurement of sulfur dioxide emissions from the East Rift Zone was about 250 tonnes per day on December 19, 2014.
Summit Observations: Inflationary tilt began in Kīlauea's summit at about 5:00 PM HST yesterday evening. The summit lava lake has shown the usual fluctuations associated with changes in spattering behavior, which are also manifested as variations in tremor amplitudes and gas release. Small amounts of particulate material were carried aloft by the plume. The average emission rate of sulfur dioxide ranged between 5,500 and 7,700 tonnes/day for the week ending on December 23 (see caveat below).
- 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.
