When Hurricane Sandy veered on Oct. 29, the sudden increase in crashing ocean waves sent rumbles through the Earth detectable on seismometers. The wave-on-wave collisions created what are called standing waves, doubling the energy directed at the seafloor, scientists reported today. The ocean gave the seafloor a little shove, sending seismic waves through the Earth.
I did not know this. Cool, huh? Not sure how they plan to use this for climate change investigations.
