Tectonic setting
The northern boundary of the Caribbean plate is a diffuse zone of varied fault types. The Muertos Trough marks the southern portion of this zone of deformation with north dipping convergence.Active Faults of the World https://books.google.com/books?id=aQUgAwAAQBAJ Yeats R. 2012 Cambridge University Press 978-0521190855 147
