    Japanese Scientists Detect Rare Deep-Earth Tremor S-wave Microseism

    Scientists in Japan studying earthquakes for the first time have detected a rare deep-Earth tremor, known as an S (secondary) wave microseism. 
    •    Microseisms are very faint tremors. 
    •    The detection was made by scientists from the National Research Institute for Earth Science and Disaster Prevention in Japan. 
    •    The rare deep-Earth tremor S wave microseism was detected for the first time and traced its location to a distant and powerful storm. 
    •    The storm in the North Atlantic known as a weather bomb which was a small but potent storm that gains punch as pressure quickly mounts. 
    •    During the storm, groups of waves had sloshed and pounded the ocean floor which struck between Greenland and Iceland. 
    •    Using seismic equipment on land and on the seafloor researchers found a tremor known as an S wave microseism. 
    •    S wave Microseisms are very faint tremors compared to P (primary) wave microseisms and they occur in the 0.05 to 0.5 Hz frequency range.
