Description

Analysis of data recorded at Sos Enattos from April 2016-February 2017 and June 2020-March 2021 shows connections between wind and seismic waveforms. Wind speeds are typically below 4m/s, so strong seismic responses to wind are rare but weaker seismic responses are still detectable. The power spectral density of seismic data reveals increased seismic energy for higher wind speeds over a broad range of frequencies (0.3-30Hz). In some cases, the root-mean-square of seismic data increases parabolically with average wind speed. Comparing results for seismometers at the surface and underground consistently shows a reduced influence from the wind on deeper seismic waveforms.
