"We use time‐reversal imaging for microearthquake location and investigate the possibility of a\r\nsimultaneous qualitative moment‐tensor estimation. We cross‐correlate the data with the synthetic\r\nstrain Green's tensor and stack individually for each moment‐tensor component. The objective\r\nfunction for the source location is then formulated as the squared sum of those stacked components.\r\nThe maximum value of the objective function corresponds to the estimated source location and\r\norigin time. Similarly, the corresponding stacked components at the estimated source location give\r\nthe entire time history of the qualitative estimation of the moment tensor. We apply the method to\r\nsynthetic data of various types of moment‐tensor sources computed for a complex and\r\nheterogeneous model, namely the Pyhäsalmi ore mine in Finland. We also test the method with the\r\nsame data adding white noise up to 40% of the absolute maximum. Although the method is\r\ncomputationally intensive, it is fully automatic and can easily be adapted to parallel processing. The\r\npreliminary results show that the method is robust and reliable."^^ . "2011" . . "2011" . . "Society of Exploration Geophysicists"^^ . . .
