Lava lake inside Kilauea has risen more than 100 feet since last week

Lava continues to erupt from a single vent in the western wall of Halemaʻumaʻu crater inside Kilauea volcano.

Lava fountains from the vent have sustained heights of about 12 meters (39 feet), according to a report today from the Hawaiian Volcano Observatory.

The lava lake inside the crater has risen about 2 meters (7 feet) over the past 24 hours. It has risen about 34 meters (112 feet) since Kilauea began erupting again on Sept. 29 for the first time since May.

No unusual activity has been noted in the East Rift Zone, HVO said.

“Ground deformation motion suggests that the upper East Rift Zone — between the summit and Puʻu ʻOʻo — has been steadily refilling with magma over the past year,” according to HVO.

Sulfur dioxide emission rates remain high, and seismicity remains elevated but stable.

The prior eruption of Kilauea began in December 2020 and lasted until May of this year. During that eruption, the lava lake inside the crater rose to about 750 feet.
