Development and Operation Experience of a Seismic Warning System for a Nuclear Power Plant

Autor: F. O. Arakelyan, U. N. Zubko, D. G. Levchenko

Publikováno v: Seismic Instruments. 54:247-253

Requirements for the seismic resistance of nuclear power plants (NPPs) considerably differ from those for of other industrial facilities due to the necessity of protecting not only the NPP itself, but also the environment from radiation hazard. Accor

Nature of 'transparency windows' in the broadband spectrum of seafloor microseisms

Autor: Vadim D. Levchenko, D. G. Levchenko

Publikováno v: Oceanology. 53:294-307

The peculiarities of the microseisms spectra shape when recording on the ocean floor in the frequency band of 0.003–20 Hz are examined. The origin of the stable minima in the microseisms spectrum (“transparency windows”) at frequencies of about

Dynamic full-wave modeling of storm microseism propagation in an oceanic environment

Autor: D. G. Levchenko, Vadim D. Levchenko, Andrey Zakirov

Publikováno v: Oceanology. 51:677-687

The full-wave modeling of storm seismoacoustic field propagation in oceanic waveguides and at the ocean-continent border in the low-frequency range from 0.01 to 1 Hz using the numerical grid method is considered. The 2D model proposed by Press and Ew

Dynamic modeling of the propagation of low-frequency seismic acoustic fields in the oceanic medium

Autor: D. G. Levchenko, Vadim D. Levchenko, Andrey Zakirov

Publikováno v: Doklady Earth Sciences. 435:1623-1626

Numerical modeling of the propagation of wave fields in heterogeneous media has developed signifi� cantly in hydroacoustics, seismic prospecting, and other fields. Since modeling of the physical processes is complicated, a number of simplifications
