Estimation of Uncertainty For Earthquake Source Inversions

Seismologists utilize seismic waveforms in order to estimate the moment tensor (mt) on a routine basis; however, it is an inverse problem, and the result has limited reliability. therefore, a realistic estimate of the uncertainty of mt is of crucial importance in evaluating solution quality. in general, two major sources of uncertainty can be recognized: observational and modeling uncertainties. the first one is associated with the data error, which may be owing to instrumental or ambient noise effects.
