The Balance Process in Subduction Zones

The subduction zone seismic-cycle is a complex phenomena with individual earthquakes as clearer manifestations. Although earthquakes are fundamentally space-extended, they are inferred to be material ruptures mostly considered as points in space. Nevertheless, in the temporal dimension, because they are plate-velocity dependent, it is less clear that they can be considered as point processes. Therefore, when considering this plate velocity in the balance analysis and assuming a locally homogeneous stochastic process hypothesis along coarse-graining upscaling it is possible to get a picture that makes sense of the whole seismic-cycle. This picture has emergent properties not available from purely seismic events, but that are more and more frequently recognized from geodetic and satellite observations, such as distant interactions and slow slip events. Taking advantage of the instrumentation installed at northern Chile, which makes use of both temporary and permanent stations from the National Seismological Center and IPOC it has been possible to obtain a well detailed picture of the seismic cycle between 2007 and 2023, that is consistent with representations obtained from geodesical measurements. We also obtain this representation for 49-year ISC catalog. We discuss possible applications of this seismic cycle representation.
