Abstract
We investigate the ablation processes of three bolides including one meteorite fall using the amplitude data. After converting the observed amplitudes of the ground displacements to the pressure amplitudes of the shockwaves (Ben-Menahem and Singh, 1981), we estimate the meteoroid diameters invoking the formula of ReVelle (1976). The results reveal the temporal changes in the meteoroid diameters along the trajectories.
