Abstract
We used full waveforms of the Hellenic Unified Seismic Network (HUSN) regional stations and a frequency range of 0.03-0.06 Hz. We calculated full moment tensors (MTs) and focused on their ISO and CLVD components. In the tested depth range of 1-20 km, the medians of ISO (=VOL) and CLVD are positive, but their 68% confidence intervals are broad due to the tradeoff of the non-DC with depth. When constraining source depths to ≥ 7 km, indicated by relocations, MTs have unambiguously positive ISO and positive CLVD, pointing to a shear-opening source process.
