1. An area within a known active earthquake zone within which no significant earthquakes have been recorded. It is not always clear whether this gap represents a zone where gradual motion takes place continually so there is no strain accumulation, or where motion is locked and strain is accumulating.
2. (shotpoint gap) In split-spread seismic reflection shooting, the distance between the shot point and the nearest groups of geophones, which is larger than that between subsequent geophone groups at larger offsets.
3. (inter-record gap) A blank space on a magnetic tape which signals the end of one block of seismic data (one seismic record) and heralds the start of another. It is used to facilitate the transfer of magnetically recorded data into a computer system.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
