India has released a radically updated seismic zonation map under the revised Earthquake Design Code (2025), placing the entire Himalayan arc in a newly created highest-risk Zone VI for the first time.

Can someone share the same in the form of a vector file?
Really need it for my study.


Thank you,
Meghma

Even a high res image seems hard to find. Best i've found was on reddit https://www.reddit.com/r/MapPorn/comments/1panz3v/map_of_india_showing_earthquake_zones_2025/

The chance of finding vector are low, but should be possible to create. First step would be to georeference this image, maybe via https://mapwarper.net/
