Scientists are now electronically filtering out the sounds of earthquakes to that they can listen to storm waves. It is usually much more common to filter out the sounds of waves so that scientists can listen to earthquakes.
The noise of waves crashing ashore creates very specific vibrations, according to study leader Peter Bromirski of the Scripps Institution of Oceanography. And those vibrations indicate how severe storms at sea actually are.
The research team has been studying seismological data on storms which goes back to the 1930's and they note an obvious trend over the past 75+ years. "There is a definite increase in severe storm events over the years that we are noticing at the recording stations," said Bromirski.
According to the National Geographic article, many scientists believe that an increase in severe storms is one of the signs of climate change.
