Resumo
PublicationAbstract
In this work we implement an automated workflow, based on the analysis of seismic
waveforms, to study the February 2018 seismic crisis in the island of S. Miguel, Azores. Our workflow
consists on earthquake detection, location, magnitude estimation, clustering based on waveform
similarity and augmentation of the catalog based on template matching. We further characterize the
focal mechanisms of selected events by moment tensor inversion. Our results show the detailed spatiotemporal evolution of seismicity during the crisis, which seems to be related to the intrusion of fluids, and
which is followed by period of surface deformation.
