The role of propagating stress waves on a geophysical scale: Evidence in terms of nonextensivity

► We examine whether the transient stresses of the seismic waves of a major earthquake (EQ) can trigger a distant significant EQ. ► The analysis draws from a nonextensive model for the EQ dynamics, the Hurst exponent, and Fisher information. ► We find that the triggered seismicity presents higher nonextensivity, increased persistency, and higher organization. ► We further relate the associated kHz electromagnetic activity with the last stage of the impending EQ generation.
