Lava activity remains confined to two vents on the north and northwest sides of Halemaʻumaʻu crater near the summit of Kilauea volcano, according to the Hawaiian Volcano Observatory.

As of 7 a.m. today, the growing lava lake within the crater was 554 feet deep — an increase of 39 feet over the previous 24 hours. The lake was at least 780 yards long on its east-west length.

The west lava vent, which is located on the lowest down-dropped block within the crater, was intermittently active. The north vent remains the most vigorous.

Sulfur dioxide emission rates remain high — estimated at around 35,000 to 40,000 tonnes/day.

Seismicity remained elevated but stable, with a few minor earthquakes and tremor fluctuations related to the vigor of fissure fountaining, according to HVO.
