Various non-earthquake noisy signals recorded in coastal and offshore regions and their Fourier amplitude spectra: a) microseisms and high-frequency ambient noise (shelf of the Baltic Sea, OBS record); b) high-amplitude microquakes (shelf of the North Caspian Sea, OBS record); c) ship traffic noise (shelf of the Black Sea, OBS record); d) explosions (coastal zone of the North Egypt, onshore record); e) noisy signals produced by engineering works (coastal zone of the North Egypt, onshore record).
