ИСТИНА

Accurate surface faulting mapping and aftershock hypocenter location make it possible to control source modeling based on wave-form analysis at telesesimic distances. For relatively small earthquake, the source is very complex. History after Spitak. Seismotectonic setting and magnitudes of studied earthquakes are very different. But each of them is largest instrumentally recorded seismic event in the place where it occurred. Aftershock sequences and surface faulting (if any) were studied by organizing expeditions.
