    Extraordinary weather occurrences

    The typhoon season is at full swing this time of year in the Japanese port city of Osaka. These hazards of nature tend to be particularly powerful in September in this destination. Thankfully, though, the 2nd largest metropolis of Japan is somewhat sheltered, which diminishes the impacts of the tropical storm. Furthermore, floods and landslides caused by typhoons are much likelier to be dangerous than the storm itself.

    Earthquakes, which take place almost on a daily basis in Japan, are the consequence of the country's location near 4 tectonic plates. In that regard, Osaka is pretty much susceptible to these natural hazards. Most of the time, though, they manifest themselves as minor tremors.

    Tsunamis are other natural occurrences the city is exposed to. They take place when an underwater earthquake sends a series of speedy waves that hit the coastline. What's more, these waves grow in size as they draw near the shore. If the danger of a tsunami presents itself, go far inland, if possible, take a vantage point or enter the tsunami-proof structure without hesitation. Besides typhoons, tsunamis are the main cause of excessive flooding.
