The floods that hit the Indonesian island of Sumatra have left behind a dramatic toll: over 500 dead, hundreds injured and more than 400 missing. The authorities speak of one of the worst disasters in recent years, worsened by torrential rains that overwhelmed entire communities. According to the National Disaster Management Agency, more than 290,000 people have been forced to leave their homes, while many affected areas still remain unreachable.

Rescuers forced to dig with their bare hands
Rescue operations are concentrated above all in the regions of North Sumatra, West Sumatra and Aceh, the most affected by the failures of river banks and massive landslides. In many areas, rescuers were only able to proceed with their bare hands, without heavy equipment, slowing down the recovery of the missing. Entire villages like those in the Agam district have been invaded by mud and debris, leaving dozens of people trapped or untraceable.
Compromised infrastructures and isolated territories
The collapse of bridges and roads made interventions even more complicated. In the Bireuen district, for example, the collapse of a bridge blocked connections between Medan and Banda Aceh, forcing residents to travel on small boats to cross the rivers. Local authorities have also declared a state of emergency until December 11, while intermittent rains continue to threaten the stability of already affected areas.
Flash floods mixed with heavy mudflow swept through Tapanuli, Sibolga, Aceh, and Padang in Sumatra, Indonesia on Thursday.

More and more frequent extreme events
The monsoon season, intensified by tropical storms, has made this flood one of the deadliest in Southeast Asia. In addition to Indonesia, serious damage and victims were also recorded in Thailand, Malaysia and Sri Lanka, where the overall toll exceeded one thousand victims. In Indonesia, some images show beaches covered in logs washed downstream, fueling suspicions about a possible role of illegal logging in worsening the impact of landslides.
A disaster that highlights how, as the climate crisis advances, extreme weather events become increasingly frequent, unpredictable and above all deadly, hitting some of the most vulnerable regions of the planet with devastating force.
