Abstract
Simple models of mass movement and seismic processes are important for understanding the mechanisms for their observed behavior. In the present paper, we analyze the dynamics of a single-block and Burridge-Knopoff model on horizontal and inclined slope with Dieterich–Ruina and Carlson friction laws. In our experiments, the slip events are distinguished by acoustic emission bursts, which are generated by slider displacement. Also acceleration was recorded on each sliding plate using attached accelerometer. In the case of the inclined slope experimental model a seismic vibrator, which produces low periodic impact (forcing) was attached to the sliding plate. This was a numerical simulation of dynamic processes occurring at one- and four-plate Burridge-Knopoff system
