Why is this in the news?

The severe cyclonic storm Murasu recently made landfall near Kothapatnam in coastal Andhra Pradesh, causing significant damage to infrastructure, agriculture, and property. Despite the widespread destruction, initial reports indicated no major power disruptions, highlighting the efficacy of pre-emptive measures and disaster preparedness efforts by state authorities. The Andhra Pradesh government also activated its ‘Mana Mitra’ WhatsApp Governance platform for real-time grievance redressal and citizen assistance during the crisis.

Background

  • India’s peninsular coastline, particularly the eastern coast, is highly susceptible to tropical cyclones originating in the Bay of Bengal and the Arabian Sea.
  • The Bay of Bengal is a major breeding ground for cyclones, with a higher frequency and intensity of storms compared to the Arabian Sea.
  • Cyclones are intense low-pressure systems forming over warm tropical oceans, characterised by strong winds, heavy rainfall, and storm surges.
  • The National Disaster Management Authority (NDMA) and State Disaster Management Authorities (SDMAs) are apex bodies responsible for disaster management in India at national and state levels, respectively, operating under the Disaster Management Act, 2005.
  • Early warning systems, including satellite imagery, radar observations, and numerical weather prediction models, are crucial for effective cyclone forecasting and timely evacuation.
  • Coastal states regularly undertake mock drills, community awareness campaigns, and infrastructure strengthening projects to enhance resilience against cyclonic events.

What are Tropical Cyclones and their Impact?

  • Tropical cyclones are violent storms that originate over tropical oceans and move over to coastal areas, bringing about large-scale destruction due to violent winds, very heavy rainfall, and storm surges.
  • They are characterised by a low-pressure centre (the ‘eye’), surrounded by a spiral arrangement of thunderstorms that produce heavy rain and strong winds.
  • The energy for tropical cyclones comes from the latent heat released when water vapour condenses into rain, requiring warm ocean waters (typically above 26.5°C) to form and sustain.
  • The Coriolis effect is essential for the formation of the rotating wind patterns; hence, cyclones do not form within 5 degrees of the equator.
  • Impacts include widespread damage to infrastructure (roads, buildings, power lines), disruption of communication networks, destruction of agricultural crops, and loss of life.
  • Storm surges, which are abnormal rises in sea level caused by the cyclone’s winds pushing water ashore, are often the most destructive aspect of a tropical cyclone, leading to coastal inundation.
  • Post-cyclone challenges involve rescue and relief operations, rehabilitation of affected populations, restoration of essential services, and management of public health issues.
  • Effective disaster management strategies encompass pre-disaster mitigation (e.g., cyclone-resistant infrastructure, mangrove plantations), preparedness (e.g., early warning systems, evacuation plans), response (e.g., search and rescue), and post-disaster recovery.

Climate Change and Coastal Vulnerability

  • The recurring incidence of severe cyclonic storms along India’s coastline underscores the increasing vulnerability of these regions to extreme weather events, potentially exacerbated by climate change.
  • This necessitates long-term strategies for coastal protection, climate-resilient infrastructure, and sustainable land-use planning to adapt to evolving climatic patterns.

Socio-economic Impact

  • Damage to standing crops, fishing boats, and thatched houses directly impacts the livelihoods of coastal communities, particularly those dependent on agriculture and fishing, necessitating comprehensive rehabilitation and compensation mechanisms.
  • The disruption to daily life and potential displacement of residents underscore the humanitarian aspects of disaster response, requiring coordinated efforts for shelter, food, and medical aid.

Challenges

1. Infrastructure Resilience

  • Despite some successes, the extensive damage to electric poles, trees, and houses indicates persistent vulnerabilities in infrastructure, particularly in rural and informal settlements.
  • Ensuring all critical infrastructure, including communication networks, roads, and public buildings, can withstand severe cyclonic impacts remains a significant challenge.
