标题： On the spatial correlation between areas of high coseismic slip and aftershock clusters of the Maule earthquake Mw=8.8

摘要： 我们研究了与2010年2月27日MW 8.8智利马乌莱大地震余震相关的集群的空间分布。 我们使用了一种最近的聚类方法，该方法基于潜在概率密度函数的非参数估计来检测形成与高密度区域相关的集群的点子集。 此外，我们使用非参数核方法为每个这些集群估计概率密度函数。 这使我们能够识别出事件频率和同震滑动之间存在关联的一组区域。 我们的结果表明，高同震滑动在空间上与高余震频率相关联。 显示英文摘要

摘要： We study the spatial distribution of clusters associated to the aftershocks of the megathrust Maule earthquake MW 8.8 of 27 February 2010. We used a recent clustering method which hinges on a nonparametric estimation of the underlying probability density function to detect subsets of points forming clusters associated with high density areas. In addition, we estimate the probability density function using a nonparametric kernel method for each of these clusters. This allows us to identify a set of regions where there is an association between frequency of events and coseismic slip. Our results suggest that high coseismic slip spatially correlates with high aftershock frequency.
