Karangetang Volcano Erupts, Sending Glowing Material Up to 400 Metres

Karangetang volcano erupted on Siau Island in Indonesia’s North Sulawesi province on November 13.

The small explosive eruption at its north crater sent glowing material about 300 to 400 metres above the crater; the ash column’s height was not observed.

Lava flowed down several parts of the volcano, travelling up to 1,000 metres west-southwest and 500 to 700 metres northwest and south.

The volcano remains at Alert Level II, and people are advised to stay at least 1.5 kilometres from its craters and outside an extended danger area 2.5 kilometres to the south-southwest.

Earlier lava deposits may still collapse, creating further lava flows or hot clouds, particularly to the south, southeast, west and southwest.

Rain could also trigger lahars or flash floods in rivers flowing from the volcano, potentially reaching the coast, so nearby residents are urged to remain alert.
