TL;DR: It is shown that isotope geochemistry and seismic velocity anisotropy provide strong evidence for trench-parallel flow in the mantle wedge beneath Costa Rica and Nicaragua, contradicting classical models which predict trench-normal flow owing to the overlying wedge mantle being dragged downwards by the subducting plate.

TL;DR: In this paper, the authors present the first regional surface velocity field for Central America, showing crustal response to interaction of the Cocos and Caribbean plates, and they infer that buoyant, thickened CNS-2-Cocos Ridge crust resists normal subduction and instead acts as an indenter to the Caribbean plate, driving crustal shortening in southern Costa Rica and contributing to trench-parallel fore-arc motion in Nicaragua as a type of tectonic escape.

TL;DR: Hagerty et al. as mentioned in this paper presented a comprehensive analysis of all the seismic and acoustic data collected thus far, and demonstrated that harmonic tremor is not a seismic propagation effect and that pressure disturbances propagate within the magma gas mixture inside of volcanic conduits.

TL;DR: A detailed geometry of the Wadati-Benioff zone under Costa Rica, obtained from seismicity recorded by a dense local seismographic network jointly operated by the Costa Rica Volcanological and Seismological Observatory, National University, and the Charles F. Richter Seismology Laboratory, University of California, Santa Cruz, was presented in this article.
