Activity Summary: Kīlauea Volcano continues to erupt at its summit and within its East Rift Zone. Active breakouts are occurring in the upper part of the June 27th flow field around the crack system near the abandoned geothermal well site. There has been no net ground tilt across the entire volcano over the past 24 hours, and the level of the summit lava lake fluctuated according to changes in spattering.
June 27th Lava Flow Observations: The lowermost breakouts from the crack system near the abandoned geothermal well site remain active. A Civil Defense overflight on Friday morning found that the most downslope breakout was approximately 5 km (3 mi) above Apaʻa Street. Satellite observations over the past few days indicate that lava is advancing slowly, both on top of and along the northwest margin of the previous flow. HVO is planning to conduct a helicopter overflight of the flow field today, although weather conditions may interfere with those operations.
Puʻu ʻŌʻō Observations: No significant changes were noted near Puʻu ʻŌʻō. The tiltmeter on the north flank of the cone recorded no net tilt over the past 24 hours, and seismic tremor remained low. Webcams revealed no strong variations in the pattern of glow from degassing vents or the configuration of the crater floor. GPS-measured deformation across the cone has shown neither extension nor contraction since July. The most recent measurement of sulfur dioxide emissions from the East Rift Zone was about 250 tonnes per day on November 26, 2014.
Summit Observations: As it was at Puʻu ʻŌʻō, there was no net ground tilt at Kīlauea’s summit over the past 24 hours. The surface height of the lava lake in the Overlook vent fluctuated by up to 10 meters (11 yards) according changes in spattering. Volcanic tremor amplitude similarly varied based on spattering activity in the lake. Small amounts of particulate material were carried aloft by the plume. The average emission rate of sulfur dioxide was 6,900 tonnes/day for the week ending on November 25 (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.
