Multiple disasters caused by torrential rains in eastern Indonesia have killed at least 55 people and displaced thousands, the country’s disaster relief agency said on Monday. More than 40 other people were missing. Mud tumbled down from surrounding hills onto dozens of homes in Lamenele village shortly after midnight on Adonara Island in East Nusa Tenggara province. Rescuers recovered 38 bodies and at least five people were injured, said Lenny Ola, who heads the local disaster agency.

Flash flooding killed at least 17 people elsewhere and at least 42 are missing, according to the National Disaster Mitigation Agency. Relief efforts were hampered by power cuts, blocked roads covered in thick mud and debris as well as the remoteness of the area on an island surrounded by choppy seas and high waves, said the agency’s spokesperson, Raditya Jati. The bodies of three people were recovered after being swept away by floods in Oyang Bayang village, where 40 houses were also destroyed, Ola said. Hundreds of people fled submerged homes, some of which were carried off by the floodwaters.
