Since 1997 we maintain and systematically update the European-Mediterranean Regional Centroid Moment Tensor (RCMT) Catalog, which contains seismic-moment tensors for earthquakes with moderate magnitude (4:55:0) in the RCMT catalog, shows that for 75% of the events, the Kagan angle measure of the similarity of two moment tensors is smaller than 20°, reflecting good agreement of the results. We describe improvements and nhancements in the dissemination of the RCMT results through our web site.
