Описание слайда:

A new type of earthquake, Japanese scientists discovered. Earthquake, described by researchers led by Professor Ito Iosihiro have ultra-low frequency. Identified seismic processes can lead to fluctuations in the magnitude 3 to 3.5 points. However, the shocks are so slow that their man does not feel. However, these variations contribute to the growth pressures in a seismically active zones. A new type of earthquake, Japanese scientists discovered.
