gujarat is most likely to be affected by earthquake
give reason why??
Answers
Gujarat is located in the “Himalayan Collision Zone”-where Indo-Australian tectonic plate slides under Eurasian plate-causing active fault lines beneath.
The Vulnerability Atlas of India (BMTPC, 1997) classifies Gujarat into four classes based on a base of 10.3 million buildings recorded in the 1991 Census and BIS standard (IS: 1893 1984).
The proportion of area in Gujarat that falls into these (MSK Intensity Scale) zones is as follows:
Very High Risk: >MSK IX (19 percent)High: MSK VIII (13 percent)Moderate: MSK VII (66 percent)Low Damage: <= MSK VI (1 percent)
Kutch District located in Very High Risk Seismic Zone – V.
Parts of Jamnagar, Rajkot, Patan and Banaskantha in High Risk Zone – IV.
Most other parts of the State lie in Moderate Zone - III and a very small part in Low Damage Zone – II.
Earthquake risk is very high in Gujarat and the State has suffered major earthquakes in - 1819, 1845, 1847, 1848, 1864, 1903, 1938, 1956 & 2001 (9 times in past 200 years). The 2001 Kachchh earthquake was the third largest and second most destructive earthquake in India over the last two centuries.
In order to provide a guiding framework to undertake mitigation investments and activities, GSDMA initiated a study for preparation of a Composite Hazard Risk & Vulnerability Atlas for the State covering six natural and man-made hazards and the physical, social and economic vulnerability of its people, assets and economy at Taluka-level. The hazards that have been examined in detail using advanced computer assisted GIS models, probabilistic analysis and detailed field studies include: earthquake, cyclone, storm surge, flood, chemical accident exposure (between 25 and 200 year return period), and importantly for Gujarat – drought, over a period of a century.
