| Abstract: | The earthquakes and tsunami on November 15, 2006 and January 13, 2007, near Simushir Island are described. Long-term and short-term precursors of the phenomena are discussed. A joint analysis of the seismological and geodetic data provided reliable interpretation of the source mechanisms of the earthquakes. The actions of the tsunami warning personnel are analyzed. Extensive experimental data on the tsunami occurrence at different sites of the Pacific Ocean are presented. The tsunami of November 15, 2006, was numerically modeled using coseismic vertical displacements of the ocean bottom calculated from GPS data. The observed and calculated data on the maximal tsunami run up are compared. |
