The activity of Nevados de Chillan seems intensified since the weekend.
Explosions accompanied by plumes more or less loaded in ash mark the new craters and the crater Arrau. It would be interesting to have information on the presence or absence of fresh magma, and whether these are only phreatic explosions.
The Sinabung had early this morning a beautiful phase of strombolian activity, characterized by a fountain of lava amount to a few hundred meters above the summit.
At midday, moderate pyroclastic flows were observed.
