accelerogram
C2Technical / Scientific
Definition
Meaning
A graph or record showing the acceleration of the ground during an earthquake.
In a broader sense, it can refer to any graphical record of acceleration vs. time, though its primary use remains in seismology.
Linguistics
Semantic Notes
A highly specialized term primarily used by seismologists, geophysicists, and earthquake engineers. It is not used in everyday language.
Dialectal Variation
British vs American Usage
Differences
No lexical differences; the term is identical in both varieties. The concept and usage are universal in the technical field.
Connotations
Purely technical and factual with no cultural or regional connotations.
Frequency
Extremely low frequency in both, used exclusively within seismology. No notable difference in usage frequency.

- (Not applicable for this C2-level technical word)
- Scientists study accelerograms to understand earthquakes.

Learning
Memory Aids
Mnemonic
Think: 'ACCELERate' + 'diagram'. It's a diagram showing how acceleration changes.
Conceptual Metaphor
EARTHQUAKE FINGERPRINT: An accelerogram is a unique 'fingerprint' of the shaking at a specific location.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation to 'акселерограмма'. While technically understood by specialists, the more standard Russian term in seismology is 'акселерограмма' or 'акселерограф' (for the instrument). The direct translation is a very low-frequency calque.
Common Mistakes
- Confusing it with 'seismogram' (which can record displacement or velocity, not just acceleration).
- Using it in non-technical contexts.
- Misspelling as 'accellerogram' or 'acellerogram'.

FAQ
Frequently Asked Questions
No, it is a highly specialized technical term used almost exclusively in seismology and earthquake engineering.
A seismogram is a general record of ground motion (which could be displacement, velocity, or acceleration). An accelerogram is a specific type of seismogram that records acceleration.
Primarily seismologists, geophysicists, and civil/earthquake engineers who need precise data on ground shaking to assess seismic hazard and design structures.
It would be highly unusual and likely confusing unless you were speaking to a specialist. In everyday contexts, you would say 'earthquake record' or 'graph of the shaking'.
