What does catastrophism mean?
Catastrophism is the geological doctrine that the Earth's major features were shaped primarily by sudden, violent events — great floods, earthquakes, volcanic upheavals, or impacts — rather than by the slow accumulation of everyday processes. The term entered scientific vocabulary in the early nineteenth century, when Georges Cuvier used catastrophic events to explain abrupt breaks in the fossil record, and it was later contrasted sharply with Charles Lyell's uniformitarianism, which held that present-day processes acting steadily over immense time account for all geological change. For much of the century catastrophism fell from favor, but modern science has revived aspects of it: the asteroid-impact explanation for the extinction of the dinosaurs is often cited under the related label 'neocatastrophism'. Today the word appears chiefly in histories of science, geology textbooks, and metaphorical uses describing interpretations of change driven by sudden rupture rather than gradual evolution.
nounThe theory that changes in the Earth's crust during geological history have resulted chiefly from sudden, violent, short-lived events such as floods and impacts, rather than from gradual, continuous processes.
- In geology: the doctrine that major features of the Earth's crust were formed by sudden, short-lived catastrophic events rather than by gradual processes.
- By extension: any general view or interpretation emphasizing sudden, dramatic events as primary causes of change.
"Catastrophism held sway until Lyell's uniformitarianism gradually won over the geological establishment in the nineteenth century."
"Early nineteenth-century geologists like Cuvier argued for catastrophism, attributing fossil extinctions to sudden upheavals."
"Some historians read the French Revolution through a lens of catastrophism, seeing rupture rather than continuity."
Rarely pluralized; the plural appears only when distinguishing different varieties or historical versions of the doctrine.
"Nineteenth-century writers proposed various catastrophisms to explain gaps in the fossil record."
Before scientists accepted slow-and-steady geology, they believed Earth's surface was shaped by global disasters — a view championed by Cuvier, who blamed mass extinctions on ancient cataclysms.

Etymology of catastrophism
Catastrophism derives from 'catastrophe', borrowed via Latin from Greek katastrophē ('an overturning'), built on kata- ('down') and strophē ('turning'). The English suffix -ism marks it as a doctrinal label, coined in the early nineteenth century to name Cuvier's school of thought. Its cognates include 'catastrophe' itself and the near-synonym 'cataclysm' (from Greek kataklyzein, 'to wash down'), while the rival term uniformitarianism was coined to oppose it directly.

How catastrophism is actually used
A technical term of historical geology and philosophy of science; outside scientific contexts it is rare and somewhat formal. Modern geology accepts elements of both gradual and episodic change, so the term often appears in discussions of intellectual history (e.g., 'Cuvier's catastrophism') or in the extended form 'neocatastrophism' for impact-driven explanations such as asteroid extinction events.
Easily confused with catastrophism
Uniformitarianism is its rival theory, holding that geological change results from slow, steady processes acting over vast time rather than sudden violent events.
