European-Mediterranean Regional Centroid-Moment Tensors

These pages host various information on seismic source characteristics in the European and Mediterranean area. Our main product is a (routinely updated) catalog of seismic moment tensors for this region. You can also read a short description of the rationale of our project.

The seismic moment tensor is a complete description of the earthquake size and source geometry. The Centroid Moment Tensor (CMT) is a reliable method for calculating moment tensors, by which the Global Centroid Moment Tensor Project systematically studies global seismicity. We use instead a modified algorithm (modelling intermediate-period surface waves) to compute Regional CMTs (RCMT) for moderate-magnitude events, not well studied at global scale.
