Kilauea Volcano’s summit lava lake continued to circulate Monday, U.S. Geological Survey Hawaiian Volcano Observatory scientists report.
The lava lake, which also occasionally spatters, producing a gas plume during the day and glow at night, has seen little net change in level in the past few days, and was about 150 feet below the rim of the Overlook vent within Halemaumau Crater as of Sunday evening, scientists said.
In addition, tiltmeters, which are used to measure tiny changes in the “tilt” or angle of the ground, have not recorded any significant trend since June 28, according to the observatory.
Seismicity rates beneath Kilauea’s summit continued within background values, with some bursts in seismic tremor recorded during periods of vigorous spattering within the vent, scientists said.
Seismicity rates at the East Rift Zone also remained at normal levels, the scientist said.
At the East Rift Zone eruption site, June 27 lava flows remained active within about 5 miles northeast of Puu Oo.
