Indonesia’s Semeru volcano spews ash and gas, killing one and leaving dozens hurt


The highest volcano on Indonesia‘s most densely populated island of Java spewed thick columns of ash, searing gas and lava down its slopes in a sudden eruption triggered by heavy rains on Saturday.

At least one villager died from burns and dozens were hospitalised.

Mount Semeru’s eruption in Lumajang district in East Java province left several villages blanketed with falling ash.

A thunderstorm and days of rain, which had eroded and finally collapsed the lava dome atop the 3,676-metre Semeru, triggered an eruption, said Eko Budi Lelono, who heads the geological survey centre.

He said flows of searing gas and lava travelled up to 800 metres to a nearby river at least twice on Saturday. People were advised to stay five kilometres from the crater’s mouth, the agency said.

“Thick columns of ash have turned several villages to darkness,” said Lumajang district head Thoriqul Haq.

Several hundred people were moved to temporary shelters or left for other safe areas, he said, adding that power blackout hampered the evacuation.

The debris and lava mixed with the rainfall formed thick mud that destroyed the main bridge connecting Lumajang and the neighbouring district of Malang, as well as a smaller bridge, Haq said.

Despite an increase in activity since Wednesday, Semeru’s alert status has remained at the third highest of four levels since it began erupting last year, and Indonesia’s Volcanology Center for Geological Hazard Mitigation did not raise it this week, Lelono said.

One man died from severe burns, and 41 others were hospitalised with burn injuries, said Indah Masdar, the deputy district head. She said two villagers were reported missing and several sand miners were trapped in isolated areas along the village river.

Entire houses in Curah Kobokan village were damaged by volcanic debris, Masdar said.

Television reports showed people screaming and running under a huge ash cloud, their faces wet from rain mixed with volcanic dust.
