A very efficient method for estimating the completeness magnitude mc and the scaling parameter b of earthquake magnitude distributions has been thoroughly tested using synthetic seismic catalogues. Subsequently, the method was employed to assess the capability of the b value in differentiating between fore-shocks and aftershocks, confirming previous findings regarding the Amatrice-Norcia earthquake sequence. However, a blind algorithm reveals that the discriminative ability of the b value necessitates a meticulous se- lection of the catalogue, thereby reducing the predictability of large events occurring subsequent to a prior major earthquake.

Abstract
A very efficient method for estimating the completeness magnitude mc and the scaling parameter b of earthquake magnitude distributions has been thoroughly tested using synthetic seismic catalogues. Subsequently, the method was employed to assess the capability of the b value in differentiating between fore-shocks and aftershocks, confirming previous findings regarding the Amatrice-Norcia earthquake sequence. However, a blind algorithm reveals that the discriminative ability of the b value necessitates a meticulous se- lection of the catalogue, thereby reducing the predictability of large events occurring subsequent to a prior major earthquake.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
