Small ash emissions were observed yesterday.A series of 4 small explosions occurred between 13:41 and 15:17 local time, generating plumes of up to 500 m height.
It is not known at the moment, if the eruptions are phreatic, i.e. the result of exploding overheated water, or caused by fresh magma arriving at the summit.
