We identify 3234 small repeating earthquakes (876 groups of repeating sequences) with magnitudes of 2.5 to 4.8 for the period from 1993 to March 2007.
One such is Parkfield, which experiences many repeating earthquakes over relatively short periods.
The researchers used records of repeating earthquakes along the San Andreas fault that Nadeau developed and maintained.

Red and green stars denote repeating earthquakes.
From the perspective of repeating earthquakes, several empirical scaling relationships have been proposed.
If this is the case, repeating earthquakes with a constant static stress drop can possibly occur.
We thank Naoki Uchida for providing a list of repeating earthquakes.
