Abstract
The paper gives a brief description of a system of spatially arranged laser strainmeters, united by the standard time signal system into a single network, installed permanently in Schultz Cape in Primorsky Krai, in Svobodny Cape in Sakhalin Island, in an underground mine near Krasnokamensk, Transbaikalia. As the whole, this system represents the eastern part of the planetary laser-interferometric seismoacoustic observatory, which additionally includes laser strainmeters, located in the western part of Russia. The paper discusses a technique to locate the signal, recorded sequentially by these laser strainmeters. Using the results of detecting the location of the signal and the obtained data of a two-coordinate laser strainmeter allows us to restore not only the place of origin of the recorded signals, but also to determine their amplitudes at each measurement site, the magnitude of the signal at the place of its generation, aperture and attenuation over the propagation distances from the source to the receivers.
