Abstract:	摘要： SUMMARY The Coulomb model for stress change estimation is considered one of the most powerful physics‐based forecasting tools, even though its calculations are affected by uncertainties due to the large number of a priori assumptions needed. The aim of this paper is to suggest a straightforward and reliable strategy to apply the Coulomb model for real‐time forecasting. This is done by avoiding all dispensable assumptions, thus reducing the corresponding uncertainties. We demonstrate that the depth at which calculations are made is a parameter of utmost importance and apply the Coulomb model to three sequences in different tectonic regimes: Umbria‐Marche (normal), Landers (strike‐slip), and Chi–Chi (thrust). In each case the results confirm that when applying the Coulomb model: (i) the depth of calculation plays a fundamental role; (ii) depth uncertainties are not negligible; (iii) the best forecast at a given location is obtained by selecting the maximum stress change over the whole seismogenic depth range. 出版者： Oxford, UK: Blackwell Publishing Ltd 出版日期： 2012-02 出處： Geophysical journal international, 2012-02, Vol.188 (2), p.583-599 資源來源： Alma/SFX Local Collection 版權： 2011 The Authors Geophysical Journal International © 2011 RAS 識別號： ISSN: 0956-540X 識別號： ISSN: 1365-246X 識別號： EISSN: 1365-246X 識別號： DOI: 10.1111/j.1365-246X.2011.05276.x
