- Η Μέθοδος ΒΑΝ είναι πειραματική ερευνητική μέθοδος για την πρόγνωση σεισμών που προτάθηκε το 1981. Η πρόβλεψη των σεισμών σύμφωνα με τη μέθοδο ΒΑΝ βασίζεται κυρίως στην ανίχνευση των σεισμικών ηλεκτρικών σημάτων (SES, Seismic Electric Signals). Στα πλαίσια της έρευνας αυτής εισήχθη το 2001 και η έννοια του «φυσικού χρόνου». (el)
- El método VAN es un método experimental de predicción sísmica, nombrado así por los apellidos de cada uno de sus desarrolladores, los físico griegos, Panayotis Varotsos, Caesar Alexopoulos y Kostas Nomikos. Este método trata de detectar y medir emisiones electromagnéticas que, de acuerdo al equipo de científicos, ocurren con días y horas de anticipación a un sismo y que pueden ser interpretadas como una señal de alerta ante una catástrofe que se aproxima.

- The VAN method – named after P. Varotsos, K. Alexopoulos and K. Nomicos, authors of the 1981 papers describing it – measures low frequency electric signals, termed "seismic electric signals" (SES), by which Varotsos and several colleagues claimed to have successfully predicted earthquakes in Greece. Both the method itself and the manner by which successful predictions were claimed have been severely criticized. Supporters of VAN have responded to the criticism but the critics have not retracted their views. Since 2001, the VAN group has introduced a concept they call "natural time", applied to the analysis of their precursors. Initially it is applied on SES to distinguish them from noise and relate them to a possible impending earthquake. In case of verification (classification as "SES activity"), natural time analysis is additionally applied to the general subsequent seismicity of the area associated with the SES activity, in order to improve the time parameter of the prediction. The method treats earthquake onset as a critical phenomenon. After 2006, VAN say that all alarms related to SES activity have been made public by posting at arxiv.org. One such report was posted on Feb. 1, 2008, two weeks before the strongest earthquake in Greece during the period 1983-2011. This earthquake occurred on February 14, 2008, with magnitude (Mw) 6.9. VAN's report was also described in an article in the newspaper Ethnos on Feb. 10, 2008. However, Gerassimos Papadopolous complained that the VAN reports were confusing and ambiguous, and that "none of the claims for successful VAN predictions is justified", but this complaint was answered on the same issue (en)
