Zusammenfassung
The use of down-hole seismic instrumentation provides substantial benefits with regard to signal quality and reduced magnitude detection threshold in earthquake monitoring. This is mainly due to reduced levels of ambient and anthropogenic noise with depth, especially within the uppermost few hundred meters. Installing vertical arrays of seismometers in boreholes also allows including the depth as third dimension in addition to surface-based measurements. The installation procedure and selection of the depth of sensors in a borehole can range from quasi-permanent installations, with a retrieving option, to permanently cemented sensors in place. While sensor layouts generally depend on the boundary conditions of a specific project and are a compromise given the substantial drilling costs involved, the improvements in noise reduction generally open new windows in earthquake seismology and geomechanical reservoir monitoring. The current installation of highly sensitive down-hole seismometer arrays in monitoring wells around the eastern Sea of Marmara in Turkey (ICDP-GONAF project) and their integration into the local seismic network for monitoring the activity along the Princes Islands segment of the North Anatolian Fault Zone are discussed and first down-hole sensor responses are presented.
