The study of the external influences from environmental disturbances is a fundamental issue in interferometric detection of gravitational wave, both in locking and in normal operation. Virgo is continuously monitored by a large number of environmental sensors, ranging from seismometers to microphones to electromagnetic probes, up to a weather station. Using data collected during the engineering runs, we have studied the features of the main external noise sources, and the way they interfere with Virgo operation and expected sensitivity. In this paper we present the preliminary results obtained.
