Explain the four characteristics of a disaster and the conceptual relationship between hazard, vulnerability, and exposure.

Welcome back — been a while! Let's pick up where you left off. 1. The four characteristics that define a disaster are: Sudden onset or rapid escalation: Disasters often occur unexpectedly or develop quickly, leaving little time for preparation. Widespread impact: They affect a large geographical area or a significant portion of a population, causing extensive damage and disruption. Overwhelms local capacity: The scale of the event exceeds the ability of the affected community or local authorities to respond effectively using their own resources. Serious disruption: Disasters cause severe loss of life, injury, damage to infrastructure, and interruption of essential services and normal societal functions. 2. The conceptual relationship in a disaster highlights the interaction between a hazard, vulnerability, and exposure. A hazard is a potential threat (e.g., an earthquake or flood). Vulnerability refers to the susceptibility of a community or system to the impacts of that hazard due to factors like weak infrastructure or poverty. Exposure is the presence of people, assets, or systems in areas where a hazard might occur. A disaster arises when a hazard impacts a population or system that is both vulnerable and exposed, leading to severe consequences that overwhelm their capacity to cope. Send me the next one 📸
