Dispersion of Rayleigh waves along a mainly Atlantic path

Summary It is shown that the dispersion curve of Rayleigh waves of an Earthquake of Haiti as observed in Budapest agrees well with those obtained byEwing &Press, as well as byBerckhemer for Atlantic route, though the latter related to purely oceanic routes, while with the curves observed at Budapest 80% of the route refer to an oceanic, 20% to continental path.
