Measuring the displacement on seismic observation of buildings is important, especially for structural health monitoring. However, there is still no standard method for measuring seismic displacement. Therefore, we studied the applicability of kinematic GNSS positioning to measure the displacement. As a result, we saw that the seismic displacement measured by GNSS positioning agrees with the seismic displacement measured by displacement meter in two examples of seismic records. Furthermore, we also saw that kinematic GNSS positioning can have higher accuracy than what is generally said when used for seismic observation.
