   The first data on earthquake in Western Bohemia date back to the close of the 12th century. The focal region is on the crossing of the significant fault systems of the Bohemian Massif, the Litoměřice deep fault and the Western Bohemian fault system (Mariánské Lázně fault and faults parallel to it) - Fig. 1. The last earthquake swarm afflicted Western Bohemia at the turn of the years 1985 and 1986. It was documented by rich macroseismic and instrumental material. The strongest shock of the swarm occurred on Dec.21, 1985 at 10h 16m UTC. It has a local magnitude ML=4.6 and an epicentral intensity 7 MSK-64. The analysis of seismograms (examples in Fig.2), especially of the local seismological stations showed that separate shocks differ in the size, focal position and focal mechanism (Fig.3). The time duration of the main part of the swarm was about 2 monts. It splits into four actived periods. Fig.4. The study of the 1985/86 earthquake swarm has been carried on.
   This investigation is especially directed towards revealing regularities in the nature of a focal process during the swarm. Understanding these physical laws we consider as a key to the prediction of earthquake in this region. At present, the inhabitants of the investigated region rarely describe the sounds that could be connected with schocks of the tectonic origin in this region. Local seismological stations record weak earthquakes from time to time. A comparison of these data with the space-time pattern of earthquakes in Vogtland in the years 1968/85, obtained on the basis of the published data on the Vogtland array, shows that contemporary seismic sctivity represents normal life of the region under investigation in the period between stronger earthquake swarms.
   Though the focal region is located in three states in respect of earthquake research and especially of desirable prediction of earthquakee in this region in the future, it is necessary to carry out the same basic investigations in all three states by the same methods and to assure a joint complex e
