The shallow boreholes at The AltotiBerina near fault Observatory (TABOO; northern Apennines of Italy)

[摘要] As part of an interdisciplinary research project, funded by the EuropeanResearch Council and addressing the mechanics of weak faults, we drilled three200–250 m-deep boreholes and installed an array of seismometers. The arrayaugments TABOO (The AltotiBerina near fault ObservatOry), a scientific infrastructuremanaged by the Italian National Institute of Geophysics and Volcanology. Theobservatory, which consists of a geophysical network equipped withmulti-sensor stations, is located in the northern Apennines (Italy) andmonitors a large and active low-angle normal fault.

The drilling operations started at the end of 2011 and were completed byJuly 2012. We instrumented the boreholes with three-component short-period(2 Hz) passive instruments at different depths. The seismometers are nowfully operational and collecting waveforms characterised by a very highsignal to noise ratio that is ideal for studying microearthquakes. Theresulting increase in the detection capability of the seismic network willallow for a broader range of transients to be identified.
