The Coulomb failure stress change (\u0394CFS) has been widely implemented to understand the spatial distribution of aftershocks. Here we propose a new metric for evaluating aftershock generation based on the energetics of shear faulting in a prestressed state. Unlike \u0394CFS, the new metric depends not only on coseismic stress changes but also on background crustal stresses. The energetics-based formulation expands the \u0394CFS defined on a specific plane into a generalized failure stress defined in a three-dimensional space. We examined the diagnostic ability of the new metric by applying receiver operating characteristic analysis to 12,175 aftershocks (M\u22650) that followed the 1992 Landers earthquake. With a realistic background stress field inferred from thousands of earthquake focal mechanisms, the new metric was able to discriminate the triggering mechanisms of the aftershocks: two-thirds were direct responses to coseismic stress changes and one-fifth resulted from strength decreases owing to pore-fluid pressure increases.", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2022-04-01", "subitem_description_type": "Other"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1016/j.epsl.2020.116103", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2020.
