Abstract

Magnetic and bathymetric data are combined with earthquake mechanism studies to produce a tectonic model for the Juan Fernandez microplate at the Pacific-Nazca-Antarctic triple junction. Presents a schematic evolutionary model which relates the formation of the Juan Fernandez microplate to differential spreading rates at the triple junction, and discusses related complexities. The future evolution of the 4 plate system depends on whether one or both ridges remain active. -from Authors
