This map was creating by warping or rectifying a non-georeferenced map to Google Maps. The source (before warping or rectification) of the earthquake zone map is http://en.wikipedia.org/wiki/File:India_earthquake_zone_map_en.svg (reference article:Earthquake hazard zoning of India). Warping or rectification was done through Harvard's World Map Warper. Control points:
- Kolkata
- New Delhi
- Mumbai
- Chennai
- Srinagar
- Thiruvananthapuram
- Guhawati
