article_snippet.sent: Ocean waves provide most of the energy that feeds the continuous vertical oscillations of the solid Earth,' said the researchers.
article_snippet.sent: As these so-called long waves travel over the ocean floor (stock image) and continental shelves they create seismic waves that oscillate much slower.
article_snippet.sent: these waves are known as long because these waves travel from the floor to the coast and back again.
