Hurricane!

Earthquakes and accompanying tsunamis/tidal waves, hurricanes, volcanic eruptions tend to be cyclical. People living in areas where these things may frequent and/or occur, relatively speaking can sometimes live an entire lifetime and never experience any of the above and this often leads to a sense of complacency. In the past few years, areas that had not experienced a direct hit from a hurricane for a generation or more were given painful reminders. Hurricane Ivan clobbered the Caribbean island of Grenada in September of 2004. At the time, the people of Grenada could barely remember what a hurricane felt like.
