Bulgaria: Satellite Monitoring & Event Situation
Track recent event signals and monitor Bulgaria 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 Bulgaria 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, 10 event signals were recorded in Bulgaria, most in the kinetic category.

Why Analysts Watch Bulgaria From Space
Bulgaria’s monitoring themes run along its two water borders. On the Danube, the Kozloduy nuclear plant cut Unit 5 output in August 2026 after what its operator called an unprecedented and critical decline in the river’s level; on the Black Sea, the Port of Varna runs terminals in the Bay of Varna and on Beloslav Lake.
Typical monitoring angles
- Danube water extent near Kozloduy during low-water periods, tracked with Sentinel-1 SAR and Sentinel-2 time series
- Wildfire hotspots and burn scars near Strumyany (Blagoevgrad) and Rani Lug (Pernik) via NASA FIRMS and Sentinel-2, as in July 2025 (Copernicus EMS EMSR822)
- Vessel activity at the Varna East and Varna West terminals with SAR ship detection
