Recently, the observation results of the microtremor have been influenced by the setting direction of the measurement instruments called pick. Array observations fit for the investigation of that reason. 3 measuring lines (containing 4 stations) are set at 6 meter intervals. And the vibration axis of the pick were changed in two directions at right angles. It was known that the sureface wave were caused by the noise of cars. For the detail investigation, at the same time , the picks were set in directions with the difference at a 45° angle. Moreover, the difference was changed at a 30° angle. The results : 90° angle The observation results of the microtremor were almost unlike. 45° angle Some elements were alike. 30° angle Some elements changed gradually.
