Abstract The interaction between seasonally-induced non-tectonic and tectonic deformation along the Himalayan plate boundary remains debated. Here, we propose that this can be significantly influenced by induced hydrological loading cycles. We explore seasonal mass oscillations continental water storage in Southeast Asia arc region using continuous Global Positioning System measurements satellite data from Gravity Recovery Climate Experiment. suggest substantially higher transient displacements above base of seismogenic zone indicate a role changes aseismic slip rate on deep megathrust may controlled loading. invoke modulation down-dip due to fault resonance process stress changes. This modulates mid-crustal ramp associated micro-seismicity influences timing Central earthquakes.
