Attenuation coefficients of the PL waves are determined from the records at three stations in Japan. The coefficients are from 0.7 to 2.6per 1000km. They show a clear tendency with period, and are well explained by the imaginary part of the complex root of the period equation for a crustal model JW-1 by YOSHII (1970).
