Resumen
Se presentan los efectos del sismo Ismit ocurrido el 17 de agosto de 1999 sobre los cambios en la composición química de aguas termales y minerales en las zonas más afectadas de (1) Kuzuluk, (2) Bursa, y (3) Yalova/Gemlik en la zona de fallas “North Anatolian”. Los muestreos se realizaron antes del evento, en julio de 1999 y después del evento, en octubre de 1999 y octubre de 2000. En estas tres áreas las aguas han mostrado cambios en su composición isotópica de 2H y 18O; de 36Cl y 13C, así como en sus constituyentes químicos y parámetros físicos durante el período 1987-1996. Tales variaciones están relacionadas probablemente con la actividad tectónica del área y la circulación inducida del agua subterránea. Effects of the August 17, 1999 Ismit earthquake include to short-term changes in the composition of thermal and mineral waters in the areas of Kuzuluk, Bursa, and Yalova/Gemlik along the North Anatolian Fault Zone. We report the results of groundwater sampling campaigns before and after the earthquake. For these three areas changes of isotopic composition in 2H and 18O of the water, and in 13C of the dissolved species of inorganic carbon, as well as changes of some chemical constituents and physical parameters, were observed. These changes are most probably related to the active tectonics of the area and to induced groundwater circulation.
