The fociMT algorithm is point-source moment tensor inversion and the fault rupture processes (e.g. directivity or spatial changes in elementary moment tensors) are NOT considered. As such, the algorithm is valid for events with simple source time functions that can…

No. There is no requirement that input data come from earthquakes displaying similar focal mechanism. The hybridMT refinement method is NOT based on empirical Green’s function technique, where this requirement is imposed. Actually, the larger the variability of focal mechanism,…
Shortly speaking, no. The moment tensor refinement method used in hybridMT algorithm is NOT using the concept of empirical Green’s function technique, although the refinement of seismic moment tensors is also achieved by suppressing the propagation effects (similarly to EGF…
“omega” parameter which is a part of ASCII input file is basically the area below the first P-wave ground displacement pulse (in time domain) or equivalently the spectral level taken from the amplitude spectrum of ground displacement pulse. The unit…
