The kinematics parameters like velocity of the flying rock during an earthquake and the collision between the helmet and the flying rock is presented. Since the seismic wave could be simplified as sinusoid individually in the horizontal direction and the vertical direction, the velocity of the flying rock is calculated separately with the acceleration and the frequency in the correspondingly orientation. Then, theoretical model of the collision process include velocity and the impact force is actualized based on the analysis of cases not only the impact between the rock and the helmet lonely but also the rock and the helmet well-worn on the rescuer’s head.
