Meaning and Definition
A geological fault where the hanging wall has moved down relative to the footwall, typically caused by extensional tectonic forces.
In a broader context, the term may be used metaphorically to describe a fundamental structural weakness or flaw that causes a system, plan, or entity to collapse or fail under its own weight.
Dialectal Variation
British vs American Usage
Differences
No significant difference in technical usage. The term is standard in the geological lexicon of both regions.
Connotations
None beyond the precise technical definition.
Frequency
More common in mid-20th century geological literature; 'normal fault' is now the dominant term in contemporary publications in both regions.

- Confusing it with a 'thrust fault', which involves upward movement.
FAQ
Frequently Asked Questions
Yes, in modern geology, 'gravity fault' is a synonym for 'normal fault'. 'Normal fault' is the more current and widely used term.
The name comes from the idea that gravity assists the downward movement of the hanging wall block as the crust is pulled apart (extended).
It would be very unusual unless you are specifically discussing geology. Most people would not be familiar with the term.
The opposite in terms of movement direction is a 'reverse fault' or 'thrust fault', where the hanging wall moves up relative to the footwall due to compressional forces.
A geological fault where the hanging wall has moved down relative to the footwall, typically caused by extensional tectonic forces.
Gravity fault is usually technical / academic in register.
Gravity fault: in British English it is pronounced /ˈɡrævɪti fɔːlt/, and in American English it is pronounced /ˈɡrævəti fɑːlt/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'gravity' pulling the hanging wall down along the fault line, like an elevator going down.
Conceptual Metaphor
A FAILURE IS A COLLAPSE (metaphorical extension: a fundamental flaw that causes a downward failure).
