Landslide Impact Analysis in Majenang, Indonesia from November 2025 Satellite Imagery

UNOSAT code LS20251118IDN maps satellite-detected landslides in Majenang Sub-district, Indonesia. UNITAR-UNOSAT identified about 30 damaged and 40 potentially affected buildings within a 500-hectare analysis area. This preliminary analysis from Sentinel-2 and Shengi-02 images acquired on 18 and 21 November 2025 has not yet been validated in the field.

Use Cases

• Mapping landslide scar extent based on the 10 hectares of observed scars
• Estimating building damage based on the identified 30 damaged and 40 potentially affected structures
• Planning field validation missions based on the preliminary satellite-derived impact analysis

Strengths

• Analysis covers a defined area of 500 hectares
• Quantifies observed landslide scars (about 10 hectares) and damaged buildings (about 30)
• Uses satellite imagery from two specific dates (18 and 21 November 2025)

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• The analysis is preliminary and explicitly noted as not validated in the field
