This kind of subduction zones always produce deep quakes and large quantities of magma, because the oceanic plate going below the south american continental plate is melting and already below Brazil.
Quoting: OXI Luisport  See the seismicity maps here... [ link to static1.emsc.eu] and here you can see the progressive depth on quakes to the plate interior... this indicates the subducted oceanic plate is sinking and melting: [ link to static3.emsc.eu] Thats a great map Luis, really shows some alarming line of strikes. A shrinking subduction zone is more than alarming.
