A volcano erupted in Indonesia on Sunday spewing a cloud of ash 15km into the sky and forcing the evacuation of nearly 2,000 people, authorities said, as they issued their highest warning for the area in the east of Java island.

There were no immediate reports of any casualties from the eruption of the Semeru volcano and Indonesia’s transport ministry said there was no impact on air travel but notices had been sent to two regional airports for vigilance.

”Most roads have been closed and now it is raining volcanic ash and it has covered the view of the mountain,” community volunteer Bayu Deny Alfianto said over phone from near the volcano.

Semeru, the tallest mountain on Java, erupted last year killing more than 50 people and displacing thousands. Indonesia’s disaster mitigation agency said 1,979 people had been moved to 11 shelters and authorities had distributed masks to residents. The eruption began at 2.46am on Saturday and rescue, search and evacuation efforts were on.

The volcano’s plume of ash reached a height of 50,000 feet (15km), said Japan’s Meteorology Agency, which had been on alert for the possibility that the volcano could trigger a tsunami. It later ruled that out. R
