katastrof

Katastrof is a term used in several languages to denote a large-scale disaster that causes extensive damage, disruption, or loss of life. It covers a broad range of events and refers to outcomes that overwhelm local capacity to cope, often requiring external aid and long-term recovery.

Etymology and usage: The word derives from Greek katastrophē, meaning an overturning or sudden turning, and has cognates in many languages, including forms such as katastrof in several European languages. The term is used in both everyday language and technical contexts to describe severe disruptive events.

Types: Catastrophes are commonly classified as natural catastrophes—earthquakes, floods, storms, wildfires, droughts, pandemics—and human-made or technological catastrophes—industrial accidents, chemical releases, nuclear incidents, and large-scale infrastructure failures. Some events involve complex interactions among hazards, vulnerability, and exposure, such as cascading failures or conflicts.

Impacts: Catastrophes produce casualties and injuries, displace populations, damage infrastructure, and cause economic losses. They can have long-term environmental effects and reshape social, political, and economic conditions for years or decades.

Response and mitigation: Preparedness, risk assessment, early warning systems, and resilient infrastructure reduce exposure and vulnerability. Effective emergency management, rapid humanitarian assistance, and long-term recovery programs aim to save lives and restore basic services and livelihoods.

Notable examples: Natural catastrophes include large earthquakes and tsunamis, such as the 2004 Indian Ocean tsunami and the 2011 Tōhoku earthquake and tsunami. Technological catastrophes include nuclear and chemical incidents, like Chernobyl (1986) and Fukushima Daiichi (2011).
