abstract
The discovery of GW signal from merging neutron stars by LIGO on 17th August 2017 was followed by a short GRB170817A discovered by FERMI and INTEGRAL 1.7 seconds after the loss of the GW signal when it just reached its maximum. Here we present a reproduction of the first paper (published by us in 1984) predicting a short GRB after GW signal of merging neutron stars. Our paper followed the scenario by Clark and Eardley (1977) who predicted a catastrophic disruption of a neutron star in a binary 1.7 seconds after the peak of GW signal. Our next paper in 1990 predicted all the main properties of the short GRB with quite a reasonable accuracy. Typos in English translation are corrected and a few comments are added in the current publication as numbered footnotes (the only footnote from the original paper is marked by an asterisk).

Latest GW neutron star merger rates are consistent with short GRBs being produced by BNS mergers if jets are wide or rates low, with NSBH mergers subdominant.
