Skeptical? I was too at first when I read this news release: Superstorm Sandy shook the Earth" (open access).
"When Superstorm Sandy struck the United States on 30 October, it didn't just devastate the Eastern Seaboard, it shook the ground as far away as the West Coast, producing tiny vibrations in Earth's crust that were picked up by seismometers there."At first I thought that the signals were being formed from the crashing waves on the shoreline, but that is only part of the signal that the researchers were detecting.
"While some of the motions were produced by surf pounding beaches, a larger fraction came from large storm waves far offshore that smashed into each other."So how is it that possible in a viscous fluid like water? Recall that the effects of surface waves are practically imperceptible more than a few meters beneath the surface due to viscous dissipation. The critical clue to the answer is provided in this sentence: "The ground motions generated by strong storms over the sea typically cycle at low frequency...". Low frequency. That's important.

Incredible as it may seem, hurricanes can induce earth movement across a continent, all due to hydrogen bonding in water.
