Resumen:
Explores the possibility of relating the remnant arc to an old subduction process and the active arc to a new subduction developed in front of the previous one. The geometry of two cases is described: a system with two subsequent parallel subduction planes and a system where the most recent subduction plane dips more steeply than the old one. The position of an eventual remnant trench can be determined from the geometric relationships between those parameters and searched on the bathymetric profiles. The models were tested on five inter-arc basins from the W Pacific. -from Author
