Long-period seismology probes the Earth's interior through the seismic passband in a period range from 50 to 500 s. The limitation of seismic transparency in this band is known but the source of limitation has been a long-standing puzzle. Here we report evidence that the transparency is limited, over the entire passband, by fundamental Rayleigh waves excited by global and random sources in a thin layer just above the Earth's surface.
