Short summary
The Nazca–South American subduction front is one of the most active in the world. We have chosen four zones along this front to do a comparative study on possible different dynamics. Data are public and well tested in the last decades. The methods are original since mutability and Shannon entropy are not always used in this kind of problem, and, to our knowledge, this is the first time they are combined. The north of Chile could be a zone with greater chances of a large earthquake.
The Nazca–South American subduction front is one of the most active in the world. We have...
