Rescue teams race against weather and unstable terrain as 21 remain missing in Cilacap and Banjarnegara following torrential downpours
Indonesia's disaster mitigation agency on Friday confirmed the death toll from landslides across two regions of Central Java has risen to 30, with 21 people still missing as rescue operations enter their second week. The National Disaster Mitigation Agency (BNPB) reported the casualties following torrential rains that triggered deadly slides in Cilacap district last week and Banjarnegara regency over the weekend.
The rising toll underscores the operational dilemma facing more than 700 rescuers deployed across the disaster zones: push forward through waterlogged, debris-choked terrain to locate survivors while managing the risk of secondary landslides that could claim more lives. With Indonesia's wet season only two months old and forecast to run through April, saturated soils and continuing rainfall threaten to trigger additional slides across the steep volcanic landscape of Central Java.
Two disaster zones, mounting casualties
BNPB spokesperson Abdul Muhari outlined the breakdown by location. In Banjarnegara regency, 10 people have been confirmed dead with 18 still missing. The slides damaged dozens of houses, injured seven residents, and forced the evacuation of nearly 900 people to temporary shelters set up in schools, mosques and village halls. Local authorities, coordinating with BNPB, have established basic services for evacuees as search operations continue.
Cilacap district has borne the heavier toll: 20 confirmed dead and three missing. Nearly 400 residents have been evacuated from at-risk zones. Authorities announced this week they would extend search operations into next week, deploying excavators to accelerate the clearing of massive debris fields that have buried homes and blocked access routes.
The scale of the response reflects the difficulty of the terrain and conditions. At least 700 personnel—drawn from police, military, search and rescue units, and volunteer teams—are working across both sites. Heavy machinery has been brought in to move earth and rubble, but the equipment itself faces limits in unstable, waterlogged ground.
The rescue clock and the weather watch
"We face several obstacles in the search, particularly with landslide ponds filled with debris and continuously flowing waters, [which] also risks new landslides due to rains," Abdul Muhari told reporters. His assessment captures the central tension: rescue teams must navigate submerged zones where debris dams have created ponds, all while rain continues to fall and destabilize surrounding slopes.
Indonesia's weather agency confirmed the wet season began in September and will persist through April. The current rainfall has already saturated soils across much of Central Java's mountainous interior, where steep terrain and dense settlement patterns combine to elevate landslide risk. BNPB has warned that continuing precipitation could trigger additional slides in areas already weakened by recent events.

Regional disaster systems under strain
The Central Java landslides add to a week of compounding weather-linked crises across the Indonesian archipelago. In East Java, Mount Semeru's major eruption on Wednesday threw ash and gas more than 13 kilometers away, with nearly 900 people staying in shelters set up in schools, mosques and village halls, while authorities evacuated nearly 190 people from the volcano's slopes, including hikers stranded at a campsite. While the eruption did not cause the Central Java landslides, the concurrent events are stretching Indonesia's disaster response capacity across multiple provinces simultaneously.
The broader Southeast Asian context reflects similar pressures. Typhoon Kalmaegi's devastation of the central Philippines earlier this month killed at least 114 people, demonstrating the regional strain on preparedness systems as extreme rainfall events test response capabilities from Manila to Jakarta.
Outlook: extended search, rising risk
Rescue operations in both Cilacap and Banjarnegara will continue into next week, BNPB confirmed, though the agency acknowledged that persistent rain and unstable ground may eventually force a transition from active search to recovery mode. The 21 missing persons represent families awaiting closure and communities unwilling to abandon hope while any possibility of survival remains.
Casualty figures are likely to rise as access improves and teams penetrate deeper into debris zones. The more significant risk, however, is that saturated soils and continuing monsoon rains will trigger new landslides across Central Java's steep interior before the wet season ends in April. With more than 1,300 residents already evacuated and temporary shelters operating at capacity, authorities face months of sustained alert and potential repeated displacement as Indonesia's most densely populated island navigates its most dangerous season.
