“…Physically speaking, classifying earthquakes in these two categories is not firmly accurate. However, isolating the background seismicity from the aftershocks, which we will refer to as catalog declustering, is crucial for a wide range of studies, such as the along‐fault monitoring of transient loading (Marsan, Prono, & Helmstetter, 2013; Marsan, Reverso, et al., 2013; Reverso et al., 2015) or fluid injections (Bachmann et al., 2011; Hainzl & Ogata, 2005; Kothari et al., 2020), and hazard assessments (Azak et al., 2018; Galina et al., 2019; Marzocchi & Taroni, 2014; Taroni & Akinci, 2021).…”
