Quaternary fault kinematics and stress tensors along the southern Caribbean from fault-slip data and focal mechanism solutions Franck A. Audemard, Gloria Romero, Herbert Rendon, Victor Cano Fundación Venezolana de Investigaciones Sismológicas Publicado en: Earth-Science Reviews 69 (2005) 181–233 Abstract: Deformation along the southern Caribbean coast, as confirmed by the compilation of stress tensors derived from fault-plane kinematic indicators (microtectonics) and further supported by focal mechanism solutions herein presented, results from a compressive strike-slip (transpressional senso lato) regime characterized by a NNW–SSE maximum horizontal stress (1H=11) and/or an ENE–WSW minimum (1h=13 or 12) horizontal stress, which is responsible for present activity and kinematics of six sets of brittle features: east–west right-lateral faults, NW–SE right-lateral faults—synthetic Riedel shears, ENE–WSW to east–west dextral faults—P shears, NNW–SSE normal faults,...
