Abstract
A description of initial excitation of spheroidal mode 0S2 initiated by the 2013 Sea of Okhotsk earthquake (Mw= 8.3) is presented. It is based on newly revealed fact of standing P-wave origination in the epicenter of the Sea of Okhotsk earthquake and excitation of traveling surface P-waves on the Earth’s surface by this wave. A new interpretation of the nature of free spheroidal Earth’s oscillations in case of strong earthquake (М ≥7,5) is proposed. The spheroidal mode 0S2 is interpreted as combination of standing and traveling P-waves, transferring the Earth’s strain energy.
