Enriching seismic network catalogues is a key object to understand the seismotectonic processes and hazard. In areas with poor knowledge of patterns, installation dense local networks essential. The enhanced density coverage improves detection events low energy. Nowadays, Machine Learning (ML) techniques are becoming widely used in seismology, addition standard automatic procedures (i.e., STA/LTA-based algorithms).In this study, we assess performance P- S-wave picking earthquake algorithms...

The great potential of the Global Navigation Satellite System (GNSS) in monitoring ground deformation is widely recognized. As with other geophysical data, GNSS time series can be significantly noisy, hiding elusive signals. Several denoising techniques have been proposed to improve signal-to-noise ratio over years. One most effective has proved multi-resolution decomposition through discrete wavelet transform. However, analysis requires long data sets effective, as well computation times,...
