The work is an attempt to clarify the nature of the amplitude- distance curve for P-waves between 87 and 110 degrees, using the spectral amplitudes of earthquakes in the Indonesian region recorded at the Swedish and Finnish seismograph stations. At the present time the results are inconclusive, because even after allowing for station and source terms there is a large unexpected scatter.
