Over the past weeks, the lava dome continued to grow at Soufrière Hills, mainly on the SW part of the dome. Rockfalls and pyroclastic flows occurred on the S side of the dome and in the upper parts of both White's and Tuitt's Ghauts. On 23 and 24 December, ash plumes rising to 3 km were observed and MVO reported that the emissions originated from a vent on the W side of the dome.

At night, incandescent rockfalls were visible from the NW and W.
