Identifying the approach of a major earthquake

Panayiotis A. Varotsos, Nicholas V. Sarlis, Toshiyasu Nagao

By analyzing the seismicity in natural time and studying the evolution of the fluctuations of the entropy change of seismicity under time reversal for various scales of different l…

A complexity measure in natural time analysis identifying the accumulation of stresses before major earthquakes

Panayiotis A. Varotsos, Nicholas V. Sarlis, Toshiyasu Nagao

Here we suggest a new procedure through which one can identify when the accumulation of stresses before major earthquakes (EQs) (of magnitude M 8.2 or larger) occurs. By analyzing…

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…

Geoelectric field and seismicity changes preceding the 2018 Mw6.8 earthquake and the subsequent activity in Greece

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

A strong earthquake of magnitude Mw6.8 struck Western Greece on 25 October 2018 with epicenter at 37.515N 20.564E. It was preceded by an anomalous geolectric signal that was record…

Interconnection of point defect parameters in solids with bulk properties: Application to diamond

P. A. Varotsos

We show that the values of the defect entropy and the defect enthalpy for the vacancy formation in diamond, have a ratio which is comparable to the one predicted by a model suggest…

Interconnection of point defect parameters in solids with bulk properties: A review

P. Varotsos

Two models have been proposed for the interconnection of the defect Gibbs energy g^i with bulk properties almost 60 and 30 years ago, respectively. The one, proposed by Zener, assu…
