摘要

•Characterization of regional seismicity in Ghana.•P- and S-phase dataset picked using deep-learning.•A conservative strategy to circumvent the problems of false negative detections.•A joint inversion was applied for the hypocentral parameters and 1D velocity model.•Clusters of events and updated seismic catalog for the region.
