Volcano erupts on same Indonesian island hit by deadly quake

A volcano has erupted in central Indonesia, prompting authorities to warn airlines about volcanic ash in the air.

Mount Soputan in North Sulawesi province spewed ash nearly 20,000ft into the sky.

The eruption status has been raised from an alert to “standby” 2.5 miles from the summit and up to four miles to the west-south-west.

“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 presents a hazard for plane engines.

Soputan is on the northern part of Sulawesi island, where a central region was severely damaged by an earthquake and tsunami on Friday.

Indonesia has dozens of active volcanoes.
