Locations Affected: Indonesia
Severe flash floods and landslides in Indonesia’s Central Java province have caused widespread destruction, resulting in at least 21 fatalities and 11 injuries. Heavy rainfall since 20 January caused rivers to overflow, affecting nine villages in the Pekalongan Regency. Other impacted districts include Kendal, Brebes, Grobogan, Pemalang, Demak, Sragen, Tegal, and Surakarta City. Flash floods have also affected several other provinces in Indonesia. A landslide was reported on 20 January in Denpasar, Bali, leading to four fatalities.
Indonesia’s Vulnerability to Landslides
Landslides frequently occur in Indonesia during the rainy season, which lasts from October to March. Mountainous regions and fertile floodplains, home to millions of Indonesians, are particularly vulnerable to floods and landslides.
Impact of the Floods and Landslides
- A landslide in Pekalongan has damaged a dam, destroyed three main bridges connecting villages, and submerged multiple houses.
- Rescue and search operations for missing people are ongoing but hindered by poor accessibility and adverse weather.
- Heavy rainfall in Batang Regency has damaged multiple bridges, six connecting facilities, and five houses.
- Almost 300 people have been evacuated to temporary government shelters in Pekalongan, while over 500 residents have been evacuated in Batang.
Outlook on the Situation
Moderate to heavy rainfall is forecasted in Central Java to continue till 24 January, potentially worsening the flooding in affected areas and triggering new landslides. Adverse weather conditions may exacerbate challenges in rescue operations. Persistent inundation and debris on roads could lead to traffic and supply chain disruptions. Potential damage to utility infrastructure may result in power and communication outages. Additionally, flooding could contaminate potable water and increase the risk of waterborne diseases. Organizations are advised to stay updated on the situation and implement contingency plans accordingly.
