Until twenty years ago the slow earthquakes were considered rare moreover non-real. Then with the dense seismological networks and the GPS monitoring places disposed in Japan, those non-typical earthquakes became to frequently observed. Nowdays, twenty years later, these slow earthquakes have been detected in Alaska, Cascadia, Mexico, Costa Rica, New Zealand, Peru and Chile. Different researchs of slow earthquakes have suggested a relationship between those non typical earthquakes which ocurred in stable sliding region and that giant thrust eartquakes which originated in the locked region. The nearbily of these locations advice the interaction between these two different kind of events. Also, it is expected that stress accumulation in the locked zone should influence stress regimes in the soubrounding region, so slow earthquakes in the stable sliding zone may change in response to stress built up in the locked zone (Obara and Kato 2016). So to better understand the great earthquake cycle, it is important to resolve the complete subduction process with all the knowledge that we have nowdays, the slow deformations and fast slips.
