00925njm 22002777a 4500 dc Olaiz Campos, J. A. author Muñoz Martín, Alfonso author De Vicente Muñoz, Gerardo author 2022-06-01 The Slip Model is applied to the Global Centroid Moment Tensor database to determine the present day state of stress. Thus, from each focal mechanism the horizontal shortening direction (Dey) and the shape factor of the strain ellipsoid (k`), defined as the relationship between the maximum horizontal shortening and the vertical axis, are calculated. Additionally, this method proposed the neoformed plane from the calculated nodal planes. In this study, to determine the stress configuration at crustal scale, only depths < 40 km are included. Focal mechanisms are grouped in reverse, strike-slip and normal, to analyse its distribution and to determine the b-parameter from Gutenberg-Richter law. Finally, global shape factor and horizontal shortening direction maps are presented. 10.3997/2214-4609.202210577 https://hdl.handle.net/20.500.14352/2580 https://doi.org/10.3997/2214-4609.202210577 Present-Day Crustal Stress Field from Gcmt Focal Mechanisms Based on the Slip Model.
