Identifying the occurrence time of an impending mainshock: A very recent case

P. A. Varotsos, N. V. Sarlis, E. S. Skordas +1

The procedure by means of which the occurrence time of an impending mainshock can be identified by analyzing in natural time the seismicity in the candidate area subsequent to the…

On a universal relation for defects in solids

E. S. Skordas

We show that the defect data parameters related to various defect processes, e.g., formation, migration, dielectric relaxation parameters, obey a universal law. In particular, the…
