Kīlauea Volcano Summit Lake Deepens to 591 Feet
Lava activity at the Kīlauea Volcano on Hawaiʻi Island remains confined to Halemaʻumaʻu Crater, with the lava lake deepening to 591 feet and maintaining its 72 acres in size.
As of 4 a.m. on Tuesday, Dec. 29, the Hawaiian Volcano Observatory reports that the lava lake was 587-591 feet deep with a narrow black ledge around it. The SO2 emissions were reduced from the day before, but remained at elevated levels.
The HVO reports that seismicity remained elevated but stable, with steady elevated tremor and a few minor earthquakes.
The HVO reports that “Geodetic monitors indicate that the upper portion of the East Rift Zone contracted while the summit deflated.” According to HVO scientists, “This was associated with magma withdrawal to feed the summit vents. There is no seismic or deformation data to indicate that magma is moving into either of Kīlauea’s rift zones.”
Two or three narrow channels of lava were visible this morning at the west vent which continued erupting lava into a lava lake within Halemaʻumaʻu crater.
Over the past day, the main island of cooler, solidified lava floating in the lava lake drifted slowly westward in the lake until about 10 p.m. on Monday night when it stalled along with 10 or so much smaller islands to the east.
The main island was about 820 feet long and 440 feet wide, and about 7 acres in area, according to the HVO.
