Feedforward reduction of microseism disturbance in a long-based interometric gravitational-wave detector was discussed. Laser interferometer gravitational-wave observatory (LIGO) which has a 4 km base-line detectors was used. Results showed that the root mean-squared displacement near 0.15 Hz can be reduced by 10 dB.
