When a natural event becomes a disaster

         Natural disaster is never purely natural. The moment when a natural event such as a hurricane, tornado, or wildfire "meets" with a societal community on its path, the event has the potential to become a disaster from the perspective of human society. Hurricanes essentially serve as nature's venue to reallocate energy geographically from the tropical region to higher latitudes. But because some communities are built on the usual path of hurricanes, they are vulnerable to this type of natural events. Hurricane Maria has left the U.S. territory Puerto Rico in despair. Because of its geographic location, Hurricane Maria certainly will not be the last one to affect this region. To build better resilience, the first thing every community needs to do is raise its awareness of such interactions between nature and society.
