A lot of seismic phenomena with small magnitude has been taking place in theLadoga lake region. One of them is the earthquake which was recorded on the31$^\text{th}$ of July, 2010 followed by an earthquake swarm near Nikonovskycape. There is only one station in the region that is why it is difficult toprocess the data. In this work we propose a new method for obtaining main eventfocal mechanism and constructing the synthetic seismograms for this event. Thedata of swarm events is used to test the method of constructing syntheticseismograms and the data of close events to determine the parameters of themedia. Since the amplitude of the wave P is close to zero, the location of thenodal plane can be submitted. That is the reason why we can find the focalmechanism for the earthquake using data of the single seismostation. Resultingfault plane has the same inclination as known tectonics line which theearthquake source is placed on. Our proposed method is based on Green functionmethod with using several kinds of sources and temporal $\delta$-shapedsequences.
