A new concept of time and its applications: Natural time

Part of the Springer Praxis Books book series (PRAXIS)


As explained in earlier chapters of this book (for example see Section 3.5), the preseismic electric signals of the VAN method (that is, the SES), are detected a few hours to several months before the earthquake. This information is obviously very important if one compares this relatively short time-window with the usual statistical estimates of the seismologists, for example that an earthquake will occur in an area after 30 years plus or minus 10 years, which in practice means that the earthquake might occur after 20 to 40 years. (Note that all these statistical seismologists’ estimates are based on the conventional concept of time, that means they count the time in years, days, hours, etc.)
