Definition
Meaning and Definition
A geological fault where the hanging wall has moved upward relative to the footwall.
In geology, a specific type of dip-slip fault where compressional forces cause one block of rock to move over another, indicative of crustal shortening. It contrasts with a normal fault.

Common Mistakes When Using “reverse fault”
- Using 'reverse fault' to describe any fault where land has moved upwards without the specific compressional, dip-slip mechanism.
- Confusing it with a 'thrust fault' (a subtype, not always synonymous).
FAQ
Frequently Asked Questions
A thrust fault is a specific type of reverse fault where the fault plane is at a low angle (typically less than 30 degrees). All thrust faults are reverse faults, but not all reverse faults are thrust faults.
Reverse faults often create uplifted, rugged topography such as fault scarps, ridges, and can contribute to mountain building (e.g., the Himalayas).
Yes, earthquakes generated on reverse faults can be very powerful and destructive, as they often occur in compressional zones near convergent plate boundaries.
Geologists look for offset layers of rock (stratigraphy). In a reverse fault, older rocks are typically pushed on top of younger rocks, which is the opposite of what is often seen in a normal fault.
A geological fault where the hanging wall has moved upward relative to the footwall.
Reverse fault is usually technical/specialized (geology, earth sciences) in register.
Reverse fault: in British English it is pronounced /rɪˌvɜːs ˈfɔːlt/, and in American English it is pronounced /rɪˌvɜːrs ˈfɔːlt/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Imagine a car reversing UP a steep hill; in a REVERSE fault, the rock block moves UP, not down.
Conceptual Metaphor
EARTH'S CRUST IS A FRACTURED SLAB. COMPRESSION IS A VISE. A reverse fault is a CRACK WHERE THE TOP SLIDE IS PUSHED UP AND OVER.
