A new database of source time functions (STFs) extracted from the SCARDEC method

Abstract : SCARDEC method (Vallée et al., 2011) offers a natural access to the earthquakes source time functions (STFs), together with the 1st order earthquake source parameters (seismic moment, depth and focal mechanism). This article first aims at presenting some new approaches and related implementations done in order to automatically provide broadband STFs with the SCARDEC method, both for moderate and very large earthquakes. The updated method has been applied to all earthquakes above magnitude 5.8 contained in the NEIC-PDE catalog since 1992, providing a new consistent catalog of source parameters associated with STFs. This represents today a large catalog (2782 events on 2014/12/31) that we plan to update on a regular basis. It is made available through a web interface whose functionalities are described here.
