Cyclonic Storms: Preparedness Phases and Medium Term Measures

Question: Cyclonic storm Ashobaa is the latest to hit the Arabian Sea Coast and it is expected to further develop into a super cyclonic storm. Discuss the preparedness phases and medium term preparedness measures for coping with such disasters.

• It is centred at 590 km west—southwest of Mumbai, 470 km southwest of Veraval and 960 km east-southeast of Masirah Island (Oman)

A. Preparedness Phases

• Identification of vulnerable areas through simulation techniques

• Identification of local resources for coping with the disaster

• Definition of catchment areas for each shelter

• Formation of medical teams and provision of list of shelters entrusted to each

• Estimation of resource requirements and list of shortfalls

• Backup for restoration of power and communication links

• This includes contingency planning, structural and non structural preparedness in the following sequence:

• Pre Cyclone Period should be made use of by local authorities for developing accurate advance warning capabilities

• Urban local bodies should remove hoardings and deploy adequate boats in areas prone to flooding as a result of cyclonic storm

• Access roads to shelters should be well maintained and upgraded prior to the onset of the storm

• Early warning systems need to be widely spread

• Latitude and longitude details of cyclone shelters should be shared with the affected persons

• Rail and road lines need to be secured and technology solutions to provide last mile connectivity should be popularised

• Wildlife sanctuaries and parks should be guarded at the time of the cyclone
