The rare deep-Earth tremor S location is traced for the first time to a distant and powerful storm.
The weather bomb North Atlantic՚s storm was a small still potent storm that gains punch as pressure quickly mounts.
Ggroups of waves had sloshed and pounded the ocean floor between Greenland and Iceland at the time of storm.
Using seismic equipment on land and on the seafloor researchers found a tremor known as an S wave microseism.
S As compared to P (primary) wave microseisms wave Microseisms are low faint tremors and occur between 0.05 and 0.5 Hz frequency range.
P wave microseisms are easily detectable during major hurricanes, fast-moving waves and travel through gaseous, liquid and solid materials.
Whereas the elusive S waves are slower and only travel through solid rock, not liquid, Humans experience them during earthquakes.
Significance of Discovery:
This new Detection will be very helpful to experts learn to get more idea about the inner structure of Earth and increase detection of earthquakes and oceanic storms.
S waves microseismic will also help to understand the deeper crust and upper mantle structure inn future.
