India has released a new seismic zonation map under the revised Earthquake Design Code 2025. The most important update is that the entire Himalayan arc has, for the first time, been placed in a newly created highest-risk Zone VI. This makes the Himalayan arc the central exam fact in the update and marks it as the most sensitive category in the revised hazard classification. The update is national current affairs and links directly with Indian geography.
The second key figure is 61%. After the update, 61% of India lies in moderate to high hazard zones. This is a significant increase from earlier estimates, so the topic should be read not merely as a map update but as an issue linked with risk-based planning, building safety and earthquake preparedness. The Earthquake Design Code connects the map with the way safety standards for buildings and structures are framed, making the update relevant at the intersection of geography, science and technology, and national current affairs.
For RAS and UPSC prelims, the likely question areas are direct and factual: which region has been placed in Zone VI, what share of India now lies in moderate to high hazard zones, and under which code the updated map was released. The static-GK linkage is with Indian physical geography, the Himalayan region and disaster-risk mapping. While revising, keep three anchors together: revised Earthquake Design Code 2025, the entire Himalayan arc in Zone VI, and 61% of India in moderate to high hazard zones.
