R3 Radio Blackout
R3 radio blackout. HF radio communication significantly degraded or impossible on the sunlit side of Earth.
Geographic Context
This solar storm event occurred at coordinates 0.00°, 0.00°.
Event Assessment
This event is a solar storm event classified as medium severity. Calamity.live has classified it as "medium" severity with a severity value of 60. The computed Calamity Score is 56 out of 100, reflecting a moderate-impact event. The primary scoring components are: population (80), historical (80), intensity (60). Data for this event was sourced from swpc, one of the 250 scientific monitoring sources aggregated by Calamity.live.
Regional Monitoring Context
This solar storm event is being tracked through Calamity.live's global monitoring network, which aggregates data from 250 scientific sources. Real-time monitoring and multi-source verification help ensure data accuracy and timely reporting of significant natural hazard events worldwide.
Cascade Risk Analysis
This event may trigger secondary hazards through cascade effects. Cascade detection is an automated process that evaluates how primary disasters can trigger secondary events — for example, earthquakes triggering landslides, or volcanic eruptions causing lahars and pyroclastic flows. These secondary hazards can sometimes pose a greater threat than the initial event, particularly in mountainous terrain or densely populated areas.
