Sri Lanka: Satellite Monitoring & Event Situation
Track recent event signals and monitor Sri Lanka from space — geolocated events, the most active areas, and satellite imagery in one place. Free to browse on the Delta Watchfloor.
Quick answer — what Off-Nadir Delta is
You can monitor Sri Lanka from space on Off-Nadir Delta — viewing Sentinel-1 SAR and Sentinel-2 optical imagery, tracking any area over time with anomaly detection, and overlaying geolocated event signals (from global news media) and active fires. In the past 7 days, 46 event signals were recorded in Sri Lanka, most in the protest category.

Why Analysts Watch Sri Lanka From Space
Cyclone Ditwah made landfall on 28 November 2025 and caused what the UN called one of Sri Lanka’s worst flood disasters in two decades, with deadly landslides in the central hill country. On the coast, the Sri Lanka Ports Authority describes the Port of Colombo as the country’s premier port.
Typical monitoring angles
- Flood extent along the Kelani River and in Gampaha, Colombo, Puttalam and Mannar districts with Sentinel-1 SAR
- Landslide scars in Kandy, Badulla and Matale compared in Sentinel-2 before/after scenes with terrain data
- Ship activity at the Port of Colombo and Hambantota International Port with SAR ship detection
