Summary Nowadays, in a passive seismic processing STA/LTA based on the cross-correlation is computed. This processing is done in order to remove the noise (Earthquake) from the natural noise. Detecting the Earthquake play a key role in passive seismic studies. However, in a passive seismic monitoring system record files contain months and years of data and manually analyzing the data can be expensive and inaccurate. In addition, in the presence of noise, detecting the arrival of weak microseismic events becomes troublemaker. In this passive seismic study, we manually determined the known earthquake. As well as, we computed STA/LTA based on the cross-correlation of the energy ratios method.
