Death toll rises to 10 after landslide at dam site in orangutan habitat The death toll from a landslide at a hydropower construction site in northern Sumatra has risen to 10, with three people still missing and feared dead. The disaster was the second landslide to hit the site in the Batang Toru forest in the space of five months. Experts and activists have again questioned the project developer’s disaster mitigation plan, warning that the area could also be hit by an earthquake, with even more devastating consequences. Conservationists also say the project threatens the only known habitat of the critically endangered Tapanuli orangutan, which numbers fewer than 800 individuals.
