An event detection and localization design was tested to study semi-automatically unusual seismic signals recorded during the growth, and the induced collapse of a salt cavity. In the proposed detection design, simple spectral signal characteristics are used to detect and characterize seismic events in complex swarming sequences. For event localization, an approach based on simple peak-to-peak amplitude estimation was tested which relied on the derivation of a site specific attenuation law. The results show the great potential of both methods to provide a reliable first order approximation of spatio-temporal attributes of the recorded seismicity.
