Fault imaging is the process in which faults are processed, identified, and visualized in various ways while conducting seismic exploration. There are multiple motivations for seismically imaging faults. Generally, the goal is to better understand the structural geology of an area, which can range in scale from basin to small-scale reservoir modeling of single formations.

Fault terminology and identification in the subsurface

Source 1: Structural Geology textbook by Haakon Fossen

A fault is "any surface or narrow zone with visible shear displacement along the zone" (Fossen). It is comprised of a hanging wall and a footwall as seen in the figure.

A fault's displacement is described by its heave in the horizontal axis and throw in the vertical axis. Calculating this throw will be discussed in the following section.

First heading

The main headings in the article are second level headings, defined with two equals signs in the wikitext. You never need to use the top-level heading style, defined with one equals sign, as it is reserved for article titles. As with a scientific article, you have plenty of freedom about how to organize your content, but the reader may have some expectations about the order and style that you may want to take into account.

Start with a brief bit of background about the subject. Relate it to other topics, using plenty of links. Create links with a pair of square brackets around key technical words and phrases.

Second heading


You can add as many sections as you think you need to 'spiral out' from the core of the topic. Use judgment to decide when to split out a separate article.


In longer articles, it may make sense to have another level of headings. There are not many occasions when you will need to use H4 headings (four = signs), so don't go there unless it's unavoidable. Never use more than four.[1]


If you have used <ref> tags in the text, you need a References section. Use {{reflist}} as a prettier and more flexible alternative to the more esoteric <references /> tag.
