All three islands are exposed to severe emergencies, but the risks differ by location. Grande Comore has particular exposure to Karthala, coastal flooding and other coastal hazards. Anjouan and Mohéli suffered extensive effects from Cyclone Chido on 14 December 2024, including damaged homes and crops, flooding, landslides, power cuts and displacement. Cyclone Kenneth in April 2019 caused at least seven deaths, more than 200 injuries and approximately 186 million US dollars in damage and losses, equal to about 16% of national GDP. Tsunamis and failures affecting roads, ports, airports, electricity, water, sanitation, health services and telecommunications also matter because island transport and supply redundancy are limited. The Direction Générale de la Sécurité Civile, under the Ministry of the Interior, coordinates with the Plateforme Nationale pour la Prévention et la Réduction des Risques de Catastrophes, island authorities, governors, communes and international partners. The Direction Technique de la Météorologie within ANACM provides meteorological information, while the Observatoire Volcanologique du Karthala monitors volcanic activity. The Comoros Red Crescent and United Nations, IFRC, World Bank, ARC and REPAIR partners may support operations. Formal systems, humanitarian assistance and local informal action coexist, and the national disaster-risk strategy for 2024–2030 provides a framework for continued improvement. Weather information may come through meteorological authorities, local officials, radio, mobile networks and community channels. TIAEWS/HADHARI began a project on 23 April 2026 to make warnings more actionable, inclusive and understandable across the islands; the project launch does not prove that nationwide coverage is complete. Households should keep water, food, medicines, lighting, a radio, a charged power bank and important documents ready, identify routes and gathering points, and plan support for children, older people, people with disabilities and pregnant people. Buildings near unstable slopes, exposed coasts, riverbeds, lava or ash areas require particular caution. During an emergency, follow verified instructions from authorities, leave threatened coasts, riverbeds, steep slopes and lava or ash zones, and avoid damaged buildings and utility lines. No single nationwide shelter and transport matrix is reliably documented, so routes, gathering points and temporary accommodation should be verified locally. Do not return until authorities give clearance. Assistance can include food, water, emergency shelter, kits and cash or voucher support, but access depends on the event, damage, vulnerability, registration, island logistics and partner presence; no universal entitlement, fee schedule or compensation guarantee is established. Recovery commonly begins with damage and needs assessments and may include temporary housing, water and sanitation, food, health, protection and livelihood support. The Post-Kenneth Recovery and Resilience Project includes resilient housing, coastal protection, roads and community infrastructure; additional financing in 2025 added 12.5 million US dollars, including work on a 12-kilometre RN3 corridor serving approximately 13,000 people.
Disasters in Comoros
Comoros faces cyclones, intense rainfall, flooding, landslides, volcanic activity from Karthala, earthquakes, coastal erosion, sea-level rise, drought and water shortages. Disaster management is shared among civil-protection authorities, island and municipal structures, weather and volcano-monitoring services, humanitarian organizations and local networks rather than one reliably documented integrated system. Preparedness, local warning channels and household plans reduce risks when transport, power, water or communications are disrupted.
Tip
Treat disaster readiness in Comoros as a local household plan supported by several authorities and community channels, not as a single nationwide service. Prioritize a usable escape route, basic supplies, reliable warnings and support for people who may need help moving. Do not depend on automatic shelter, transport, compensation or emergency assistance.
