Revised Indian Earthquake Zoning Map from Probabilistic-Deterministic Analysis

373.9 MB of geospatial data derived from a combined probabilistic–deterministic seismic hazard analysis for India. The dataset, authored by Ravi Kanth Sriwastav and last updated in April 2026, supports the development of a revised earthquake zoning map. It is available in TIF and SHP file formats under a CC-BY-4.0 license.

Use Cases

• Generate seismic hazard maps for India based on the combined probabilistic–deterministic analysis described.
• Inform regional building code specifications using the revised earthquake zoning data.
• Model ground motion scenarios for disaster preparedness and planning based on the hazard analysis.
• Conduct comparative studies of seismic risk across different regions of India using the zoning map data.

Strengths

• Dataset size of 373.9 MB suggests detailed geospatial coverage.
• Data is derived from a combined probabilistic–deterministic methodology, as stated in the description.
• Available in standard geospatial formats (TIF, SHP) for compatibility with GIS software.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
