Laboratory modeling of landslide and seismic processes triggering

The modern concept of seismic and landslide  processes relays mainly on the model of frictional instability.  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. We investigated stick-slip process: triggering of instabilities by recording acoustic emission, accompanying the slip events. 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 frequency impact (forcing) was attached to the sliding or/and immovable plate. We can impose an external periodical mechanical loading to sliding plate and at several points of fixed plate individually or together. Simple landslide model triggering effect is depend on inclination angle, numbers of vibrators, distribution and triggering signal amplitude
