Talasso-Fergana fault zone researching on the base of earthquake data with m <5
Spatial-temporal variations of weak seismicity parameters were analyzed in the region of Talasso-Fergana fault in Tien Shan on the period 1962-1995 years. Heterogeneity of seismic process characteristics was showed in different fault sections. Relatively movable areas were revealed near the fault in the sense of energy migration of weak seismic events. Obtained results were compared with new seismic tomography P velocity models for upper part of lithosphere.
