Commonly used terms and definitions
A fault section, usually defined with the OpenSHA GeoJSON file format. A fault section has, at a minimum, a unique ID number, a fault trace, dip, rake, and upper/lower seismogenic depths. Some large faults, e.g., the San Andreas Fault, may be broken down into a number of different fault sections (e.g., Coachella, Mojave, etc...).
A small subset of a fault section, usually with length approximately equal to half of the down-dip width of the fault.
A collection of [fault sections](#fault-section] for a region.
A single path through a model's epistemic logic tree; usually specifiying a combination of input data and model parameters used.
A supra-seismogenic ruptures for which multiple fault sections participate
TODO
A Rupture Set defines all of the on-fault supra-seismogenic ruptures in a fault system, and their properties (magnitude, rake, etc).
TODO
An inversion technique used in the UCERF3 Grand Inversion. See Wikipedia entry for more information.
A Solution defines the annual rate of occurrence of each supra-seismogenic ruptures from a Rupture Set, and may also supply information about gridded seismicity.
An earthquake rupture that ruptures the entire seismogenic width of the fault, usually with M≥6.5 (depending on the seismogenic width and scaling relationships used). In a Rupture Set, this refers to a unique set of fault subsections.
