Earthquakes evidence consecutive stages of inverse cascading of seismic activity to main shock and direct cascading of aftershocks. The first may reflect coalescence of instabilities at the approach, while the second indicates readjustment in a new state of a complex system of blocks-and-faults after a catastrophe. The cascades observed in seismic dynamics are by far more diverse than a power-law family easily tractable in computer and mathematical modeling.
