OVSICORI-UNA reported that on 25 December a phreatic eruption from Laguna Caliente, a summit lake of Poás, was seen by visitors standing at a viewpoint to the S of the crater. Lake water mixed with sediment and blocks was ejected 550-600 m above Laguna Caliente.

MVO reported that during 11-19 December activity from the Soufrière Hills lava dome continued at a high level. Frequent pyroclastic flows were noted on the northern flank. Ashfall also occurred on many other Caribbean islands, as far as Puerto Rico (400 km ENE), and disrupted commercial flights. (Source: GVP)
