Introduction
Natural disasters such as earthquakes, floods, cyclones, and tsunamis can lead to significant human casualties and disruption. However, the severity of impact, especially the ratio of deaths to those affected, is not uniform and largely depends on the type of disaster, the level of preparedness, and population density.
Type of Calamity
Different disasters have varying death tolls. For instance, tsunamis and earthquakes usually cause more fatalities due to sudden onset and lack of warning, while droughts affect more people over time with fewer immediate deaths. Cyclone Amphan (2020) caused fewer deaths due to early warnings, while the 2004 Indian Ocean Tsunami led to massive loss of life.
Preparedness and Early Warning Systems
Areas with disaster management systems, evacuation plans, and public awareness show reduced mortality. Japan experiences frequent earthquakes but has low fatalities due to earthquake-resistant infrastructure and public drills. In contrast, Haiti’s 2010 earthquake caused massive deaths due to poor preparedness and infrastructure.
Population Density
Highly populated areas like urban slums are more vulnerable due to congested living conditions and inadequate housing. The Bhopal Gas Tragedy (1984) in a densely populated area led to thousands of deaths. Similarly, floods in densely populated regions cause higher casualties due to delayed evacuation and limited access to relief.
Conclusion
Thus, the ratio of fatalities in disasters depends not only on the natural event but also on human and systemic factors. Improving preparedness, infrastructure, and public awareness is crucial to minimize disaster-related deaths.
