摘要：We study the spatial distribution of clusters associated to theaftershocks of the megathrust Maule earthquake MW 8.8 of 27 February2010. We used a recent clustering method which hinges on a nonparametricestimation of the underlying probability density function to detect subsetsof points forming clusters associated with high density areas. In addition,we estimate the probability density function using a nonparametric kernelmethod for each of these clusters. This allows us to identify a set of regionswhere there is an association between frequency of events and coseismicslip. Our results suggest that high coseismic slip is spatially related to highaftershock frequency.
