Short-term Earthquake Prediction Based on Seismic Precursory Electric  Signals Recorded on Ground Surface.





“What today seems impossible, is tomorrow’s reality”



   The term “earthquake prediction” refers to the knowledge of the earthquake prognostic parameters, that is the location, the time of occurrence and its magnitude, for some time before it takes place. According to the prognostic time window it is distinguished as: long-term, referring to a time window of some decades of years, medium-term, referring to a time window of a few years (2-3) and short-term, referring to a time window of the order of up to a couple of months, while sometime the term “immediate” is used when the time window is of the order of a few days.


    The aim of this web site is exactly this:


a. to present the implemented earthquake prediction deterministic specific procedure, by which,  after introducing different physical models  that are related to the seismicity and physical properties of a seismogenic area,  allow us to use conventional physics laws and mathematical analysis for the calculation of the individual prognostic parameters.


b. to give the opportunity to other scientists, being interested in the topic of earthquake prediction, for further research related to the seismic precursory electric signals.


   For the fulfillment of the aim of this web site, all the  details of the methodology (theoretical analysis, application examples on real large EQs, used hardware, collected raw data for the period 2003 - 2012),  a detailed monograph (374 pages) under the title "Short-term Earthquake Prediction" written by Dr. Thanassoulas (Geophysicist) and published on 2007, are freely downloadable in PDF form.


   We hope you will enjoy  touring in this web site (it takes some hours to visit all of it) and encourage you to apply and test this methodology in your own country (provided it is a seismogenic one).
