Short summary

The developed numerical inversion technique based on the least square inversion and a truncated SVD approach were applied to recovering the initial tsunami waveform. The method presented allows one to control the instability of the numerical solution. Analyzing the singular spectra of the matrix obtained during numerical calculations one can estimate the future inversion by a certain observational system that will allow offering more effective disposition for the registrators by precomputations.
