The eruption of Indonesia’s Semeru volcano has killed at least 14 people and injured dozens, the disaster mitigation agency BNPB said on Sunday, as search teams looked for victims in a landscape covered in deep layers of ash.

Semeru, the tallest mountain on Java island, threw up towers of ash and hot clouds on Saturday that blanketed nearby villages in East Java province.

The eruption severed a strategic bridge connecting two areas in the nearby district of Lumajang with the city of Malang and wrecked buildings, authorities said.

A BNPB official said in a news conference late on Sunday that 14 people had been killed. Fifty-six were injured and 1,300 had been evacuated.

Most injuries were burns, the authorities said.

In the Sumberwuluh area, thick, grey ash coated damaged houses, while volunteers tried to turn away motorists who wanted to go back to their homes near Semeru.

In a barren landscape covered in ash, homes were almost completely submerged, and a truck had only the top of the driver’s cab visible. Some villagers fleeing their homes managed to bring livestock with them. Grey fallen trees lie on roads, the witness said.

Other obstacles include heavy rocks and hot volcanic sediment.
