In OpenSHA, an Earthquake Rupture refers to an event that generates seismic energy as a result of slip on a fault. For large and relatively well-studied events, a rupture may be represented as a portion of a fault that slips during the event. For smaller and less well-studied events, a rupture may be represented simply as a point source. An Earthquake Rupture is defined by a:
A location on a Rupture Surface that marks where earthquake slip nucleates.
An Earthquake Rupture with an associated probability of occurrence. See also Probabilisitic Earthquake Source.
