Indonesia has dozens of active volcanos.
A volcano has erupted in central Indonesia at Mount Soputan in North Sulawesi province spewed ash 6000 meters into the sky Wednesday morning.
The eruption status was raised from an alert to standby 4 kilometres from the summit and up to 6.5km to the west-southwest.
Standby status means people should avoid the area nearest the volcano and have masks available in the event of ashfall.
Planes were warned of the ash clouds because volcanic ash is hazardous for plane engines.
Soputan is on the northern part of Sulawesi island, where a central region was severely damaged by an earthquake and tsunami Friday.
