In this work the data of the earthquake catalog of the NOAA, NationalGeophysical Data Center (NGDC) are processed in terms of global seismic energyrelease. The determined Global Cumulative Seismic Energy Release (GCSER) graphas a function of time, is analyzed in the magnitude domain (discrete energywindows). Characteristic components of the analyzed graph are: its accelerateddeformation character observed for energy windows lower than the backgroundseismicity (M = 7.0 - 7.5), its lock state that started on 1923 and longseismic quiescence periods that preceded recent mega - earthquakes. Thebackground GCSER value oscillates during the last century with a period of 60years and with increasing amplitude. The recent (1952 - 2012) 5 mega -earthquakes are closely related to the amplitude increase of the GCSERoscillation. Hence, it is suggested that more mega - earthquakes are probabledue to occur in the future. A global mechanism is postulated for the generationof the mega - earthquakes based on the principles of the non-linearity of theearth, the Markovitz wobble and the expanding earth. The determination of themagnitude of the 5 recent mega - earthquakes by the Lithospheric Seismic EnergyFlow Model (LSEFM) method indicates that the latter is globally applicable.  Key words: Global seismicity, expanding earth, mega - earthquakes, Markowitzwobble, background seismicity, magnitude determination
