The results of seismic noise analysis during West Bohemia seismic swarm (September 2011) are presented in the Jeroným Mine. Eight characteristics of the noise were used which include mutlifractal parameters and wavelet-based entropy. The main peculiarity of the resulting time series of mean values of seismic noise parameters with time step1 hour is their daily periodicity. Besides that some statistics extract periodicity of 1 week. The seismic swarm manifests in non-stationary behaviour of the noise parameters which includes breaking the daily periodic structure and existing of irregular spikes.
