This paper introduces a unified model of lithosphere–ocean coupled resonance, demonstrating how Earth’s solid crust and global ocean system operate as an interconnected harmonic structure. Using the Qindra Core Framework, the study reveals that lithospheric vibrational modes, seafloor oscillation patterns, and large-scale oceanic wave modes form a coherent network of planetary resonance pathways. We show that seismic standing waves, tectonic stress rhythms, ocean basin eigenfrequencies, and tidal-forced oscillations become phase-locked through nonlinear Earth–ocean feedback. This coupling produces stable resonance modes capable of modulating seismicity, long-period ocean waves, coastal energy patterns, and deep-water circulation. The work establishes that the lithosphere and ocean are not independent systems; instead, they form a resonant dual-layer oscillator, driven by gravitational forcing, Earth rotation, and internal energy release. These coupled modes provide new insight into the emergence of long-period geodynamic cycles, oscillatory tectonic behavior, and energy propagation across the Earth system. The model strengthens the growing evidence that planetary harmonics permeate all geophysical domains, linking deep Earth processes to large-scale oceanic dynamics through a coherent resonance architecture.
