Cyclone Harold has caused widespread devastation across Vanuatu, Fiji, Tonga and the Solomon Islands, with the storm forecast to intensify as it heads towards Papua New Guinea, New Caledonia and Australia. Cyclones can reach wind speeds of up to 250km/h and produce heavy rainfall, storm surges and flooding. The immediate impacts of cyclones are often the most severe, including damaging or destroying buildings, roads, bridges and other infrastructure. The long-term impacts can affect the economic, social and cultural development of affected areas, including the reduction of agricultural productivity and vulnerability of communities to future disasters. Preparing and responding to cyclones requires a combination of individual, collective and institutional efforts.
Cyclone Threatens Islands and Coastlines in the Pacific
A powerful cyclone is approaching several island nations and coastal states in the Pacific, posing a severe risk to life, property, and infrastructure. As of May 3, 2021, Cyclone Harold has already struck Vanuatu, Fiji, Tonga, and the Solomon Islands, causing widespread devastation and displacement. The cyclone is expected to intensify and move towards Papua New Guinea, New Caledonia, and Australia, potentially affecting millions of people.
What is a Cyclone?
A cyclone is a type of tropical storm that forms over warm oceans, typically between 5 and 20 degrees latitude, and rotates counterclockwise in the Southern Hemisphere and clockwise in the Northern Hemisphere. Cyclones can reach wind speeds of up to 250 km/h or more, and produce heavy rainfall, storm surges, and flooding. Cyclones are also known as hurricanes, typhoons, or tropical cyclones, depending on the region where they occur.
What are the Impacts of Cyclones?
Cyclones can cause a wide range of impacts, depending on their strength, location, and duration. The immediate impacts of cyclones are often the most severe, such as:
– Damaging or destroying buildings, roads, bridges, and other infrastructure.
– Disrupting power, water, and communication systems, leading to shortages and outages.
– Injuring or killing people and animals, either directly or indirectly through floods, landslides, or debris.
– Displacing people from their homes or communities, either temporarily or permanently, creating humanitarian crises and social disruptions.
– Contaminating or degrading the environment, including soil, water, and air quality, and exacerbating existing environmental problems.
The long-term impacts of cyclones can also be significant, affecting the economic, social, and cultural development of the affected areas. Some of the long-term impacts include:
– Reducing agricultural productivity and food security, due to crop loss, soil erosion, and water scarcity.
– Increasing the vulnerability and exposure of communities to future disasters, due to weakened infrastructure, uncontrolled urbanization, and limited access to resources and services.
– Compromising the ecological integrity and biodiversity of the affected areas, through habitat destruction, species loss, and pollution.
– Exacerbating social inequalities and political conflicts, due to unequal access to resources, decision-making, and justice.
How to Prepare and Respond to Cyclones?
Preparing and responding to cyclones requires a combination of individual, collective, and institutional efforts, based on the best available knowledge, resources, and technologies. Some of the key measures for preparing and responding to cyclones include:
– Developing and implementing early warning systems, that can detect, predict, and disseminate timely and accurate information about cyclones, their intensity, and their potential impacts.
– Establishing and maintaining evacuation plans, that can enable people to move to safe and secure shelters or locations, before, during, and after the cyclone.
– Stockpiling and distributing essential supplies, such as food, water, medical equipment, and fuel, to ensure basic needs are met during and after the cyclone.
– Strengthening and retrofitting critical infrastructure, such as hospitals, schools, airports, and ports, to reduce vulnerability and increase resilience to cyclone hazards.
– Mobilizing and coordinating local, national, and international resources, including human, financial, and material resources, to support the response and recovery efforts.
Q. What Should I Do if a Cyclone is Approaching My Area?
A. If a cyclone is approaching your area, you should stay informed about the latest updates from reliable sources, such as government agencies or media outlets. You should also prepare your home and family for the potential impact, by securing loose items, gathering supplies, and identifying safe locations and routes. If you are advised to evacuate, you should follow the instructions and guidelines provided by the authorities and move to a designated shelter or location.
Q. Can I Protect My Property from Cyclones?
A. While it is not possible to completely protect your property from cyclones, you can take some measures to minimize the damage or loss. For example, you can install shutters or storm panels on your windows and doors, reinforce your roof and walls, trim or remove trees and branches that pose a risk, and secure any loose objects in your yard or balcony. You should also review your insurance coverage and policy, and consider adding additional coverage for cyclone-related risks.
Q. What Should I Do After a Cyclone has Passed?
A. After a cyclone has passed, you should assess the damage to your property and surroundings, and prioritize your safety and health. You should avoid touching or stepping on any downed electrical wires or floodwaters, which can be electrically charged or contaminated. You should also check on your family, friends, and neighbors, and offer or ask for help as needed. You should register with the local authorities and humanitarian organizations, and follow their guidance and assistance for the recovery process.
