A series of small, probably phreatic explosions occurred at the volcano's summit crater early on Tuesday. INETER indicated the activity took place between 6:41 - 8:50 local time and consisted of at least 2 explosions, which generated a small steam and ash plume rising to about 200 m height.

INETER believes that these eruptions were an isolated event and not sign of a new eruptive phase with new magma involved, but most likely caused by the sudden vaporization of overheated infiltrated rain water. The alarm level of the volcano was not raised and no particular measures are planned.
