The Centroid Moment Tensor is a good summary of the fault rupture happening during an earthquake. We here describe a method for its determination in case of large earthquakes (with magnitude greater than 6.5) recorded world-widely by permanent digital seismic stations networks, as well as how deploying it on a Grid computing facility finally enabled its fast completion. Two different approaches of this process used over the last years are herein detailed and discussed. Some important impacts of this work are then highlighted and future trends are foreseen.
