The sensors, spaced 1.5 cm apart, were used to record seismic events resulting from the release of 5 rocks in a seismology laboratory. The methodology involved instrumental tests, equipment assembly in a controlled environment, and data extraction into the MSEED format using the ObsPy library. During data interpretation, challenges were identified, such as a 10% amplitude loss in the LSOL station due to a sampling rate of 90 sps, while the LSBM operated at 100 sps, along with the identification of the P-wave phase. Detailed analysis facilitated the determination of the calibration factor between the stations, essential for converting the electromagnetic pulse into soil mechanical movement, concluding with a linear regression model that established the calibration factor at 928.187 COUNTS.CC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/SismologiaCalibração de sismógrafoAnálise de dados sísmicosEspectrogramas de eventos sísmicosFator countSeismologySeismograph calibrationSeismic data analysisSeismic event spectrogramCount factorbachelorThesisCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS
