Abstract

The free oscillations of the Earth excited by one of the strongest earthquakes of the past decade (Japan, 2011) are analyzed using strain data obtained with precision laser interferometer-strain meters located in the North Caucasus (near Elbrus) and in Crimea (Sevastopol). Theoretical (PREM model) and observed oscillatory modes (North Caucasus) are compared.
