An Analysis of the Generalized Vicinity of a Large Earthquake Using Regional Data: The Kuril–Kamchatka Region


The method for constructing the generalized vicinity of a large earthquake as put forward and implemented in (Rodkin, 2008, 2012, 2020; Rodkin and Tikhonov, 2016) was previously used for analysis of world earthquake catalogs only. The use of this method for the analysis of regional catalogs presupposes a lower magnitude threshold for classification of large events and incorporation of regional seismicity peculiarities. We constructed the generalized vicinity from regional data for the Kuril Islands and Kamchatka. The same seismicity features have been identified as those for the generalized vicinity based on worldwide data; in particular, we identified the effect of earthquake hypocenters getting shallower in the near vicinity of a large earthquake. However, the regional data revealed the unexpected effect of a temporary clustering of large earthquakes, including those cases where they were far from each other. The volumes of higher activity involve considerable parts of the subduction zone far from each other both along the trench and over depth. We have estimated characteristic parameters of these clusters and the fraction of statistically dependent and independent large events. The mutual influence of seismicity at different depths has been discussed.
