WebDec 31, 2024 · Then, we analyze the Atlantic ridge seismicity, using the global centroid moment tensor catalog, finding that our method allows better constraining distribution parameters, allowing the use more data than estimations based on a single completeness level. This leads to a sharp decrease in the uncertainties associated with the parameter ... WebThe Global Centroid Moment Tensor (GCMT) Database, formerly known as the Harvard CMT (HRV) catalog has produced centroid moment tensor (CMT) solutions since 1976 (Dziewonski and others, 1981; Ekström and others, 2005). The group routinely calculates CMT solutions with a three-to-four day delay .
