The effusive eruption at the volcano continues.

The lava flow from the western vent continues to supply to the Halemaʻumaʻu lava lake. The surface activity, outside the lava lake, occurs from breakouts along the margins of the crater on the northeast, east, south, and west sides.

From available HVO monitoring deformation data, the ground has been fluctuating (periods of uplift and subsidence) over the past week varying between values of 1 (inflation) to -2 (deflation) microradians, as seen in the attached graph.

Sulfur dioxide (SO2) emissions reached to a 1150 tonnes on 12 August.

The crater floor has risen by 136 meters since the eruption began.
