Japan: Satellite Monitoring & Event Situation
Track recent event signals and monitor Japan 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 Japan 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, 64 event signals were recorded in and around Japan, most in the kinetic category.

Most active areas
Event data powered by the GDELT Project. Figures cover the mapped region around Japan and update hourly. For situational awareness only — not for tracking or targeting individuals.
Why Analysts Watch Japan From Space
Japan sits on the Pacific Ring of Fire and in the main typhoon corridor, so its satellite story is one of rapid-onset hazards: earthquake damage, volcanic activity from Sakurajima to Mount Asama, and typhoon flooding. Dense urban coastlines mean even moderate events have visible footprints.
Typical monitoring angles
- Post-earthquake damage assessment comparing pre/post Sentinel-1 SAR scenes
- Volcanic thermal anomalies and ash plumes at active volcanoes via FIRMS and optical imagery
- Typhoon flood mapping across low-lying urban plains with SAR
Monitor Japan From Space
Off-Nadir Delta lets you watch Japan without any GIS software. View Sentinel-1 SAR (all-weather, day or night) and Sentinel-2 optical imagery, draw any area to build a time series with anomaly detection, and overlay active fires.
The Delta Watchfloor adds the event layer: geolocated signals in and around Japan, ranked by severity, that you can connect to satellite imagery in one tip-and-cue workflow.
