The seismic records of the three years have been compared to check whether the measures to restrict human activity, due to the COVID-19 pandemic in 2020, have led to a decrease in seismic noise in the area. In addition, the noise levels of the station have been characterised and the main sources of seismic noise in the area have been located. To achieve these objectives, the seismic noise variations have been studied and analysed using the PSD spectral power density calculation method7 p.application/pdfengcc-by-nc-nd (c) Sáez, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/Soroll sísmicConfinament (Emergència sanitària)COVID-19Treballs de fi de grauSeismic noiseLockdownlCOVID-19Bachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
