Short-Term Properties of Earthquake Catalogs and Models of Earthquake Source (2004, methodology): “Table 3 in Kagan (2003) demonstrated that the shortest interearthquake time interval in catalogs depends strongly on seismogram frequency and methods of seismic record interpretation.”
Bayesian Estimation of the Spatially Varying Completeness Magnitude of Earthquake Catalogs (2010, background): “…this second definition, which assumes the validity of the Gutenberg–Richter law, in other words, the self-similarity of earthquakes (e.g., Wiemer and Katsumata, 1999; Wiemer and Wyss, 2000; Cao and Gao, 2002; Marsan, 2003; Kagan, 2002, 2003; Woessner and Wiemer, 2005; Amorèse, 2007; Iwata, 2008).”
Aftershock Zone Scaling (2002, methodology): “The seismic moment is distributed according to the power law; the Gutenberg–Richter relation is a logarithmic transformation of the law (Kagan, 2002a).”
Evaluation of space–time point process models using super‐thinning (2011, background): “…with the catalog considered here are well known, including potentially missing data at lower magnitudes, greater depths, and farther from seismometers in the seismic network, as well as missing events of low magnitude in the immediate vicinity just following major events (see e.g. Kagan, 2003).”
Regression problems for magnitudes (2006, methodology): “where β∗ U = Sup{β : Un(β) ≥ −Un}, (28) β∗ L = Inf{β : Un(β) ≤ Un}.”
