We analyzed the IRIS broadband seismograms for the June 9, 1994, Bolivia earthquake, the largest deepfocus earthquake ever recorded. We inverted the record sections with a duration of 330 sec which include P, pP and sP phases, and obtained a dipslip mechanism: (dip(δ), rake(λ), strike(ф)) = (13°, 4°, 1°) or (89°, 103°, 95°), with a scalar moment of .
