2002 Mw 5.9 Earthquake Using Source Scaling Law

In Calderoni et al., 2005, a section of text that was pres-ent in the original manuscript was inadvertently deleted dur-ing composition. The section entitled “Random Summation of Aftershocks (RNDS) ” is printed correctly below. Random Summation of Aftershocks (RNDS) RNDS (Joyner and Boore, 1986) generates synthetic seismograms of the target earthquake at a generic station (STAT) through the following equation: N Main AfterGM (t) wGM (s t) , (13)STAT STAT j j1 where is the ground-velocity time history of aAfterGM (t)STAT colocated subevent recorded at the same station. Time his-tories were preprocessed similarly to the ESR technique and randomly added with a shift time sj uniformly distributed between 0 and source duration T. According to Joyner and Boore (1986), the scaling factor w and the total number N in summation (13) are obtained through the ratios of the seismic moments of the two events 1/3M0,Main w (14) M0,Afte
