The sudden eruption was accompanied by a thunderstorm and rain, which pushed lava and smoldering debris and formed thick mud that destroyed at least one bridge connecting two main villages of Pronojiwo and Candipuro, as well as hampering the evacuation, Lumajang district head Thoriqul Haq told TV One.
“Thick columns of ash have turned several villages to darkness,” Haq said, adding that several hundred people were moved to temporary shelters or left for other safe areas.
Television reports showed people running in panic under a huge ash cloud, their faces wet from rain mixed with volcanic dust.
The 3,676-metre (12,060-foot) Semeru, the highest on the country’s most densely populated island, had last erupted in January, with no casualties.
Indonesia, an archipelago of more than 270 million people, is prone to earthquakes and volcanic activity because it sits along the Pacific “Ring of Fire,” a horseshoe-shaped series of fault lines. Indonesia has about 128 active volcanoes.
