Alpukat Merapi

 YOGYAKARTA: Indonesia's Mount Merapi erupted three times on Tuesday, killing at least 13 people and causing thousands to flee as it emitted searing clouds and volcanic ash.

Twelve bodies were found by rescuers at a house near the volcano and a baby died elsewhere, with predictions that the toll was likely to rise.

Before the latest eruptions people living in the shadow of Indonesia's most active volcano had been warned to evacuate or risk being killed.

"We heard three explosions around 6:00 pm (1100 GMT) spewing volcanic material as high as 1.5 kilometres (one mile) and sending heat clouds down the slopes," government volcanologist Surono told media.

Yogyakarta city search and rescue official Taufiq told reporters that 12 people had been killed at one location.

"The bodies were found around the house of Merapi's gatekeeper Mbah (grandfather) Marijan," he said.

"Some were found inside the house, others outside. They were burnt by heat clouds.

We've not found Mbah Marijan yet."

The house of Marijan, the traditional spiritual keeper of the mountain, is about four kilometres (2.5 miles) from the peak, in Sleman district.

"There are likely to be more victims as the terrain is difficult, roads are damaged and trees uprooted, it's dark and the condition of the volcano is still unstable," Taufiq added.

Local TV station reported that 15 bodies were found in and around the house. Footage showed Marijan's burnt house and several bodies covered in ash being put in body bags.

Earlier, a doctor at Muntilan hospital, Sasongko, confirmed the death of a baby, telling TV station: "The baby had severe breathing difficulties from inhaling volcanic materials and we could not help it."

The baby's death was the first reported fatality from the volcano in central Java, around 25 kilometres (15 miles) north of the cultural capital of Yogyakarta.

At least 24 people were treated at the same hospital for breathing difficulties, while elsewhere five men suffered burns.
