The project aims to investigate the possibility of monitoring microseismicity due to fluid injection in sedimentary rocks. The drill hole which is used for the frac-experiment is situated in Gross Schoenebeck, 45 km north of Berlin. Here a sedimentary cover of 4.2 km exists. Between 3.8 and 4.2 km depth (open hole area) 2829000 l of fluid were injected. Continous seismic recordings were made at 28 stations from 25th February to 7th March 2003, including the injection phase, with a sampling rate of 1000 Hz.
