Unfortunately, the whole of Japan is in the zone of increased seismic activity. For all its long history, the country has suffered many times from destructive earthquakes. To the soil fluctuations of 4-5.5 points, local residents have long reacted relatively calmly.

But, since Japan is an island country, the threat of tsunamis is added to the threat of earthquakes. High waves do not always come after earthquakes, although it is believed that they can be caused by fluctuations of any intensity. In fact, most often tsunamis are formed after earthquakes of 6 points or more. In addition, it can be caused by typhoons, which are often brought here from the Pacific Ocean. So the probability of a tsunami as a result of natural disasters should be more accurately called average.

The meteorological services and agencies of Japan inform about such a threat in advance. If it is high, many leaders release employees home, cancel flights of air and land transport, and evacuate the population from coastal cities. It is necessary to know that even after announcing the possibility of a tsunami, it does not always come in.
