The number of people killed by flash floods and cold lava flow from a volcano in western Indonesia over the weekend has risen to 41 with 17 more missing, a local disaster agency official told Agence France-Presse (AFP) on Monday, May 13.
Hours of heavy rain caused large volcanic rocks to roll down one of Indonesia's most active volcanos into two districts on Sumatra island Saturday evening, while flooding inundated roads, homes and mosques. "Data as of last night, we recorded 37 dead victims... But from this morning it has grown again, the figure reached 41 (dead)," Ilham Wahab, West Sumatra disaster mitigation agency official, told AFP.
Rescuers were searching for 17 still missing, three in Agam district and 14 in Tanah Datar, both the worst-hit areas of the flood and home to hundreds of thousands of people, he said. Ilham could not confirm the number of locals evacuated because officials had encouraged "people to evacuate to relatives' places, which are safer" than tent shelters in heavy rains. "We are focused on first, searching and rescuing the victims, second, protecting the evacuees, protecting the vulnerable people," he said.
Roads in the districts were turned into rivers, with mosques and houses damaged. Heavy rains inundated neighborhoods with muddy flood waters and swept vehicles into a nearby river, while volcanic ash and large rocks rumbled down Mount Marapi. Cold lava, also known as lahar, is volcanic material such as ash, sand and pebbles carried down a volcano's slopes by rain.
Authorities sent a team of rescuers and rubber boats to look for the missing victims and to transport people to shelters. The local government set up evacuation centers and emergency posts in several areas of Agam and Tanah Datar.
Indonesia is prone to landslides and floods during the rainy season. In 2022, about 24,000 people were evacuated and two children were killed in floods on Sumatra island, with environmental campaigners blaming deforestation caused by logging for worsening the disaster.
