Abstract
We present several statistically optimal adaptive and robust algorithms for accurate location of microseismicity using small-aperture surface arrays which show superior results in comparison with semblance-based Seismic Emission Tomography algorithm for the events with double-couple focal mechanisms and better suppress coherent noise of hydraulic fracturing
