Unusual focal mechanism, either near vertical motion on a near vertical trench-perpendicular plane, or trench-parallel motion on a sub-horizontal plane with a shallow dip towards the trench.

@m_ashrafy Thank you. The model is limited to a single fault plane. So, if the rupture occurred on several faults with different geometries and/or slip kinds, it should reflect in a difficulty to model the waveforms correctly. There is room for that since waveforms are not perfectly fitted

@InSeismoland The fact that the two planes cannot be discriminated may reflects mainly the lack of clear directivity, and possibly the lack of near enouth stations in this case.
