Flash Floods Kill at Least 16, Displace Hundreds in Indonesia

Severe flash floods triggered by intense monsoon rainfall have killed at least 16 people in Indonesia’s North Sulawesi province. In addition, the disaster has displaced hundreds of residents, authorities said.

The floods struck the Siau Tagulandang Biaro Islands district early on January 5, 2026. Days of heavy rain caused rivers and streams to overflow, sending torrents of muddy water, rocks and debris through villages on Siau Island.

Search and Rescue Ongoing

Emergency teams, supported by BNPB, police and military units, deployed to the worst-hit areas. However, damaged roads and disrupted communication networks slowed access to several villages.

As floodwaters receded on January 6, rescuers recovered 16 bodies. Meanwhile, teams continued searching for at least three people still missing in areas where entire neighbourhoods were submerged.

Emergency Response Declared

Authorities declared a 14-day emergency response period to accelerate relief efforts. As a result, aid agencies began distributing food, temporary shelter and medical assistance to affected families.

At least seven houses were completely washed away. Moreover, more than 140 homes suffered moderate to severe damage. Over 680 residents have since taken refuge in churches and public buildings.

Infrastructure Damage and Health Concerns

Initial medical assessments identified multiple injuries among survivors. Consequently, emergency teams evacuated vulnerable residents to safer locations.

At the same time, local authorities worked to clear blocked roads and restore access to isolated communities. Heavy equipment and relief supplies were mobilised to support recovery operations.

Risk of Further Flooding

Officials urged residents to remain vigilant. According to weather forecasts, additional rainfall could trigger more flooding or landslides in already affected areas.

This disaster follows a broader pattern of extreme weather in Indonesia. In recent months, monsoon rains have caused deadly floods and landslides in several regions, including Sumatra.

Ongoing Climate Challenges

Overall, the floods highlight Indonesia’s continued vulnerability to extreme weather events. In remote areas, limited infrastructure and difficult terrain often worsen the impact of natural disasters, especially during the monsoon season.
