Study of Seismic data from the Cadí (LEGEF-IEC) Broadband Station

Abstract

Verifying the quality of data recorded by seismic stations is essential, particularly when the station is part of a broader seismic network. In this study, we assess the data quality of the Cad´ı (LEGEC-IEC) broadband station. This evaluation is conducted through the elaboration, analysis, and comparison of cumulative Power Spectral Density (PSD) spectra, Root Mean Square (RMS) amplitude values, and the examination of various seismic events. The results indicate that the recorded data exhibits expected seasonal and frequency-dependent patterns, the ambient noise levels are within acceptable limits, and the station reliably captures global seismic events. Consequently, we conclude that the data produced by the station is of high quality and temporally consistent; therefore, the station is operating correctly
