“Northern” and “southern” California regions are delimited at latitude 36.5° N.
* 99 denotes the time unit value is unavailable.
† Magnitude type as given in the source.
‡ Source is the catalog version from which earthquake record was taken (UCERF2, Felzer and Cao, 2008; UCERF3, Felzer, 2013).
§ Reasons for exclusion: 1, aftershock denoted in UCERF catalog; 2, foreshock denoted in UCERF catalog; 3, below magnitude–completeness threshold for space–time volume (Felzer, 2008); 4, located west of Cascadia trench; 5, located east of trench at 29.3 km depth and within the Gorda Plate.
