Temporal pattern of global seismicity indicates temporal clustering of large earthquakes (Mw≥8.2) followed by relative quiescence (stress shadow). It is a characteristic seismic pattern along the plate boundaries. Clustering of the largest earthquakes during 1950s to 1960s followed by the extended period of low-moment release until 2003 and then again heightened moment release since 2004 has been observed, which represents a seismic temporal pattern of 50 years period.
