Direction Finding of Earthquake Epicenters by Laser Strainmeters

The article considers the possibility of determining the direction finding on the epicenters of earthquakes located at significant distances from the locations of laser strainmeters using the triangulation method, based on the data from laser strainmeters, located on Cape Shultz in Primorsky Krai, near the city of Krasnokamensk and the village of Neutrino (Kabardino-Balkarian Republic). Additionally, a method for localization of sources of various vibrations based on the use of data from a two-coordinate laser strainmeter is considered. The ways of improving the obtained results are described, based on the use of additional laser strainmeters in the system of spatially distributed laser strainmeters, which are currently in operation of recording variations in deformations of the earths crust on Popov Island and in the Crimea. The obtained results confirm the possibility of using the created planetary laser interferometric seismoacoustic observatory for recording and bearing sources of natural and artificial signals at any planetary distances.
