Characteristics of focal mechanisms in Chile subduction
Geodesy and Geodynamics, 2012 We use the Centroid Moment Tensor (CMT) solution of the earthquakes occurred in Chile subduction to analyze the characteristics of focal mechanisms. We define the angle between P, B, and T axes of focal mechanisms and three stress axes of tectonic stress

A functional tool to explore the reliability of micro-earthquake focal mechanism solution for seismotectonic purposes [PDF]
Solid Earth, 2021 Abstract. Improving the knowledge of seismogenic faults requires the integration of geological, seismological, and geophysical information. Among several analyses, the definition of earthquake focal mechanisms plays an essential role in providing information about the geometry of individual faults and the stress regime acting in a region.
