PROBLEM TO BE SOLVED: To provide an earthquake motion intensity prediction method and a disaster prevention system using real-time earthquake information, capable of estimating/evaluating an earthquake motion intensity in an assumed position with precision higher than that of conventional one, based on the real-time earthquake information. SOLUTION: A correction factor reflected with a ground characteristic in the assumed position is calculated based on an observation record concerned in the earthquake motion intensity obtained in the ground in the assumed position in the past or the ground in the vicinity thereof, and based on the earthquake motion intensity in the assumed position estimated by a distance damping expression based on a hypocentral position and a magnitude of an earthquake. The earthquake motion intensity in the assumed position is predicted by multiplying the earthquake motion intensity in the assumed position estimated by the distance damping expression, based on the hypocentral position and the magnitude in the generation of the earthquake, with the correction factor, when obtaining the real-time earthquake information including the hypocentral position and the magnitude in the generation of the earthquake.
