During 20-26 January, HVO reported an active lava surface about 200 m below a vent in the floor of Kilauea's Halema'uma'u crater.
The lava surface occasionally spattered, and both rose and drained through a hole in the cavity floor.
A plume from the vent drifted multiple directions, dropping small amounts of ash, and occasionally fresh spatter, downwind.
Lava from beneath the Thanksgiving Eve Breakout (TEB) and rootless shield complex flowed SE through a lava tube system.
Thermal anomalies detected by satellite and visual observations revealed active lava flows on top of the pali from lava-tube breakouts.
During an overflight of Pu'u 'O'o crater on 19 January scientists saw a recent but inactive lava flow across the bottom of the crater.
On 22 January a small part of the crater rim collapsed in front of the web camera, revealing an incandescent vent at the base of the E wall.
During 23-26 January, incandescence was seen from the vent, as well as from high on the E wall, the crater floor, and low on the S wall.
