O1 g 6. 0 hz <br />Vertical 0.008 g 6.0 hz <br />Radial 0. O1 g 5, 5 hz <br />1 / No frequency corrections necessary. <br />To facilitate comparison with the record of a velocity seismometer <br />we convert to velocity and displacement as follows: <br />Acceleration ti (27(f) (Velocity) ~ (2r(f)Z (Displacement) <br />where f =dominant frequency of record <br />Maximum Maximum <br />Velocity Displacement <br />Transverse: 0, 1 in/sec 2, 65 X 10-3 in. <br />Vertical: 0, 08 in/sec 2, 1 X 10-3 in. <br />Radial: 0. 11 in/sec 3, 2 X 10-3 in. <br />
