Question

Union Minister for Science & Technology and Earth Sciences has released Seismic Microzonation reports for Delhi and Kolkata. The purpose of this microzonation is to

• A. cut down the expenditure of government by enabling targeted compensation during earthquakes
• B. creation of specialized and dedicated administrative for each microunit
• C. identify geo-morphological and geological variability within a macro zone
• D. to demonstrate the resolution capability of new Cartosat satellite

Answer 1

The correct option is C

identify geo-morphological and geological variability within a macro zone

Union Minister for Science & Technology and Earth Sciences has released Seismic Microzonation reports for Delhi and Kolkata.

Earlier a seismic zoning map for entire India was prepared and published by the Bureau of Indian Standards (BIS). It had classified the entire country into 4 major groups viz. Zone-V (High intensity), Zone – III (moderate seismic zone), Zone- IV (high seismic zone) and Zone-II (Low intensity). These zones encompass wider area for which specific design spectra is commonly used, despite geo-morphological and geological variability within the respective zone.
