Indonesian authorities are searching for several hundred tourists after Mount Barujari on Lombok island spewed a massive column of ash into the atmosphere. More than 1,100 others have been evacuated, the country’s disaster agency said on Wednesday.

The ash column reached 2,000 metres. nearly 400 foreign and local tourists had been registered since Sunday to climb the mountain, leaving from the Sembalun monitoring post, about 11km from the crater.
