Abstract
Following the Chilean earthquake of 1960 May 22, important additional evidence on the distributions of the density ρ, incompressibility k, and rigidity μ in the interior of the Earth arose from recordings of free Earth oscillations with periods up to the order of one hour. A few hundred separate modes of free Earth oscillations have now been recorded and any acceptable Earth model has to be compatible with the better determined observational periods of these modes.
