India plans “Geotechnical Characterisation” of 30 cities

SHARE

India: The Ministry of Earth Sciences (MoES) of India has planned “Geotechnical Characterisation” of 30 cities in the country.

MoES is mandated to provide the country with best possible services in weather/climate, ocean state, earthquakes, tsunamis and other phenomena related to earth systems through well integrated programmes. The Ministry has planned to take up Seismic Hazard Microzonation (SHM) of urban agglomeration of 30 targeted cities spread over the county on 1:25000/50000 scale during the 12th Five Year Plan period. SHM is to be performed based on a hierarchical model for seismic microzonation with emphasis on “Geological Condition” and “Ground Condition Mapping” as cardinal components in evaluation of accentuated seismic hazard on “Site Amplification”. The exercise will involve generating multi-thematic maps like soil classification map, N value maps for different depth zones, liquefaction susceptibility maps, Vs30 map, etc. It will also cover generation of subsurface lithological distribution, different lithological cross section in cities etc. in grid pattern on 1:25,000/1:50,000 scale. It will also include integration of multi-thematic data in GIS base and preparation of ground Condition Map based on holistic Geotechnical Characterization.
