The Bransfield Rift (El Rif del Bransfield)

The result of observations and the aeromagnetic profiles through the gravimetric river basin, along with the geologic studies throughout the coasts of the South Shetland Islands, as well as registered seismic and volcanic activity throughout this region has demonstrated that the Bransfield Strait is a dynamically active rift in total expansion. The regional aeromagnetic observations have allowed a more precise identification of the rift and its relation to the active volcanism of the area.

The aeromagnetic map shows a series of linear, in "echelon", and to a great extent parallel magnetic anomalies in the direction of main the structural course of the Bransfield Strait.
