Seismic noise: unfortunate companion of seismic measurements but also a scout from the Earth's depths
Růžek, Bohuslav ; Zedník, Jan
Seismic records are contamined by noise. In classical approach elastic waves generated by an earthquake or a quary blast are considered as a deterministic signal and seismic noise as a random signal. Commonly noise is removed or at least reduced by filtering. In recent years also an opposite approach appeared. Propagation of noise followed the same principles as for the deterministic signals - it is medium dependent.

In the present contribution, description of software package for seismic data transmission and processing in OS Linux are given. Some examples of type analysis for several focal zones of mining induced seismic events and preliminary velocity characteristics are also presented.

Five temporary seismic stations were put into operation in the region delimited by the towns Ostrava-Opava-Hranice na Moravi. These stations are primarily operated in order to collect data from quarry blasts and mining induced events. Corresponding recordings will be used for the velocity model inversion. A strong quarry blast in Jakubčovice was recorded by 8 stations and interpreted
