The **data** extracted from the broadband stations are in MiniSeed format; therefore not further conversion is needed, only into .mat files. In this case we followed the same procedure as for the Cubes, we took the time **data** of each explosion to cut the MiniSeed file 30 s before it and 60 s after it and save it in Matlab files. The only problem we addressed in this step was that the coordinates of the broadband stations were daily calculated and differ from one day to another in some decimals. In order to have a final station coordinates we calculated the mean of all these daily GPS coordinates.
