Abstract
PL modes in the earthquake seismogram were discussed again. Theoretical dispersion curves for three watercovered crustal models were computed by OLIVER and MAJOR'S and SU and DORMAN'S methods. The transition from the oceanic PL to the continental PL was discussed. Analyzed records are rather “new” and are supported by the high accuracy of time and the suitable instrumental response. Crustal thicknesses were determined from observed group velocities of PL modes. Some discussions on the dispersion of the PL mode which was represented in HUNKINS and KUO'S paper were also given.
