Abstract: On the evening of October 1, 1995, a M-S = 6.1 earthquake destroyed the city of Diner, SW Turkey. Within 48 hours after the main shock, a team of the German Earthquake Task Force arrived in the area to investigate possible earthquake-related changes in the chemical-chemical composition of shallow and deep groundwater's. A mapping was pet-formed to characterise different groundwater types and a continuously monitoring station was installed within the geothermal field of Afton. Repeated measurements, performed 1, 6, 12 and 18 months after the event, reveal post-seismic changes in water discharge, water temperature, and conductivity. We will focus on the changes of spring water discharge observed in the vicinity of the epicentre. In the first month after the earthquake the groundwater discharge increased at springs located within the down-thrown block, whereas a slight decrease was observed at sites on the hanging wall.
