The Nature of Coseismic Ground Vibrations in the Epicentral Zone of the Sea of Okhotsk Earthquake, May 24, 2013, and Estimation of P-Wave Amplitudes at Teleseismic Distances

Resumo

The GPS-based coseismic observations in the epicentral zone of the earthquake on the Sea of Okhotsk of May 24, 2013, are analyzed. The peculiarities of the changes in amplitudes of seismic waves with distance are revealed on the basis of records from Russian and worldwide seismic stations. The global propagation of P-waves is investigated for the Sea of Okhotsk and Bolivian (June 9, 1994) earthquakes, and the respective amplitudes are estimated at teleseismic distances.
