Abstract. Experiments based on the BK model for stick-slip motions in one-dimensional mass-spring systems were conducted using ten blocks. The movements of each block at every 1/30 second were recorded by video pictures and the state of each block at every time step is classified into stick or slip. It was found that the power law holds between the size of slip event and its frequency. It was also clarified that the ratio of coupling spring constant to the driving spring constant larger, the smaller the power becomes.
