| Abstract | Secular changes in global geodynamic parameters (polar motion excitation, length of day, and J(2), etc.) are significant to understand internal mass transport in the solid Earth system and surface geophysical fluids related to global climate. However, the glacial isostatic adjustment (GIA) and climate-driven surface mass redistribution are insufficient to explain the origin. We are motivated to report the significance of seismic effect in the pursuit of understanding the budget of secular changes in geodynamic parameters. The seismic effect is comparable to the GIA effect and amounts to 20% or larger (up to 30%) of the observed secular changes in global geodynamic parameters. Therefore, the seismic effect must be treated as one key mechanism of driving secular changes in geodynamic parameters, which is critical to invert rheological structure, clarify internal dynamic processes, and reveal the physical evolution of the Earth. |
