Summary:The analysis of seismotectonic deformations associated with the seismogenic activation of the Chilean subduction zone at the beginning of the 21st century is reported. The constructed models of source zones of the three strongest ( M ≥ 8) earthquakes that occurred in the Chilean subduction zone in 2010, 2014, and 2015 are presented. A comparative analysis of the stress release during these events was carried out. It has been established that the 2010 Maule earthquake could have contributed to the initiation of the 2015 Illapel earthquake.
