Owing to its geo-climatic, geological and physical features, Gujarat is vulnerable to all-major natural hazards (Drought, Flood, Cyclone, Earthquake, Tsunami etc.). The State is also under constant threat of industrial (chemical) disasters which is well supported by the fact that 35% of the total Major Accident Hazard (MAH) units of the country are located mostly at Vapi, Hazira, Ankleshwar, Dahej ect. In addition, occurrence of biological disasters and other technological/human caused hazards such as transportation accidents, terror attacks, radiological accident etc. are most likely in the State.

GSDMA has developed Gujarat Hazard Risk & Vulnerability Atlas. This is the first geographically explicit Level 1 assessment of its kind outside the United States that integrates six hazards viz. earthquake, flood, cyclone, tsunami, drought and industrial (chemical) accidents, covering whole State of Gujarat. The vulnerability of the State to six major hazards as per this Atlas is described below in brief:

Cyclone:

  • Gujarat falls in the region of tropical cyclone. With the longest coast line of 1600 km in the country, it is highly vulnerable to associated hazards such as floods, storm surges etc.
  • Most of the cyclones affecting the State are generated in the Arabian Sea. They move North-East and hit the coast particularly the Southern Kutch and Southern Saurashtra and the Western part of Gujarat.
  • Two cyclonic storm seasons are experienced in Gujarat: May to June (advancing southwest monsoon) and September to November (retreating monsoon).
  • The Hazard Risk and Vulnerability Atlas prepared by GSDMA shows the Cyclone hazard zonation along with the basic wind speed at the Taluka level (Figure 1). Over 120 cyclones originating in the Arabian Sea had passed through Gujarat over a period of 100 years. Figure 1 shows a maximum wind
  • Figure 1 shows a maximum wind speed class of more than 55 m/sec along the Saurashtra coast, specifically in Porbandar, Jamnagar and Junagadh districts, which are exposed to high intensity cyclonic and storm impact. The 51 to 55 m/sec class extends further inland to cover much of Jamnagar, part of Rajkot, Junagadh and Kutch districts. The 48 to 50 m/sec class extends to most of Rajkot, part of Amreli and Jamnagar districts including Jamnagar, Rajkot cities and parts of Kutch. The 45 to 47 m/sec class covers much of Saurashtra and all of Kutch. This is followed by the 40 to 44 m/sec class that gets its swathe from Kutch through northern Saurashtra all the way to the coast of Gulf of Khambhat and southern Gujarat. The rest of the State falls into the 34 to 39 m/sec class.

Drought:

  • Gujarat is one the chronic drought prone State of India, with an average annual rainfall about only 700 mm with more than half of the Talukas of Gujarat receiving rainfall within the range of 200-400 mm.
  • Substantial portions of the State are arid to semiarid. With large parts of North Gujarat and Saurashtra having no sources of alternate irrigation, drought vulnerability increasing with groundwater overexploitation. Falling water tables put added stress on crops and water supplies.

Flood:

  • The climatology of Gujarat is influenced by the Arabian Sea in the West and three hill ranges along its Eastern border. A long coastline makes parts of arid Saurashtra and Kutch occasionally experience very high rainfall. These occasional heavy rainstorms are responsible for most of the floods in the State. While the Northern part of the State is mostly arid and semi-arid, the Southern part is humid to sub-humid. Extremes of climate, be it rainfall or temperatures are quite common in this region.
  • All major rivers in the State pass through a wide stretch of the very flat terrain before reaching the sea. These flat lowlands of lower river basins are prone to flooding. Cities like Ahmedabad, Surat and Bharuch are located on the flat alluvial plains of large rivers.
  • Concentrated runoff resulted by heavy rainfall cause flash floods in the small river basin of Saurashtra and Kutch because of their fairly impervious catchments (rocky or black cotton soils) and steep sloping upper catchments.
  • Figure 3 shows the majority of the area of Gujarat is flood prone, irrespective of the size of the catchment.
  • The flood prone river sections were identified from settlement level analysis. Flood prone river sections in Saurashtra extend to the upper basins due to the presence of dams which have to resort to emergency discharge during heavy rainstorms. Even small valleys in Saurashtra are used for agriculture. Hence flooding in these zones impacts both residents and settlements.

Earthquake:

  • Whole of Gujarat region has earthquake hazard of different levels from moderate to high as zones III to V are assigned to it in the seismic zoning map of India.
  • In the Seismic Zoning Map of India the Gujarat region is divided into three zones. Kachchh region (about 300km x 300km) is assigned zone V where earthquakes of magnitude 8 can be expected. A belt of about 60-70km width around this zone covering areas of North Saurashtra and areas bordering Eastern part of Kachchh are assigned zone IV where intensity VIII can be expected mainly due to earthquakes in Kachchh and some local earthquakes along North Kathiawar Fault in Northern Saurashtra. Rest of Gujarat lies in zone III where intensity VII can be expected due to moderate local earthquakes or strong Kachchh earthquakes.
  • The estimated mean taluka earthquake PGA zonation for a 100-year return period is presented in the figure 4. All of Kachchh, almost the entire coastline of northern Saurashtra that adjoins Kachchh and a small area in Patan district fall into the very sever intensity zone over a 100-year return period.
  • The cities of Ahmedabad, Bharuch, Rajkot, and Bhavnagar fall into the severe intensity zone, while Bhuj and Jamnagar fall in the very severe intensity zone over this time frame.

Tsunami:

  • Gujarat is prone to Tsunami risk due to its longest coastline and probability of occurrence of near and offshore submarine earthquakes in the Arabian Sea.
  • Makran Subduction Zone (MSZ) -South West of Karachi is an active fault area which may cause a high magnitude earthquake under the sea leading to a tsunami.
  • In past, Kandla coast was hit by a Tsunami of 12 mtrs height in 1945, due to an earthquake in the Makran fault line. Tsunami prone areas in the State include coastal villages of Kutch, Jamnagar, Rajkot, Porbandar, Bhavnagar, Anand, Ahmedabad, Bharuch, Surat, Navsari and Valsad districts.
  • The Hazard Risk and Vulnerability Atlas prepared by GSDMA shows (Fig. 5) the estimated inundation based on Probable Maximum Surge (PMS) at highest high tide level.
