摘要

Earthquake prediction in a time domain of a few weeks to months is the ultimate goal of earth scientists who have been attempting to evaluate seismic, geodetic, hydraulic, geochemical, isotopic, etc. precursors for this purpose. Two recent attempts toward earthquake forecasting in India’s Koyna-Warna seismic area (Gupta et al. 2006, 2007) using earthquake nucleation phenomena were successful. Other precursors such as soil gas radon were recently attempted in a reservoirtriggered seismic area (Sukhija et al. 2007). Earlier studies (Gupta et al. 2000; Chadha et al. 2003, 2008) have demonstrated that pore pressure changes in such areas could be a valuable precursor; also promising were a large number of geochemical precursors studied in active seismic areas along geological faults (Virk et al. 1994; Igarashi et al. 1995; Tsungoai and Wakita 1995; King et al. 1995; Gupta et al. 2002; Das et al. 2006). In this paper we report for the first time significant temporal changes of δ13C values of dissolved inorganic carbon (DIC) in groundwater associated with earthquake processes in a reservoir-triggered seismic area.
