There is enough power and possible destruction in each type (and more) that you mentioned here. The fact is we may not know how much destruction is carried in a storm, etc. until after it has happened....that within itself should cause concern, if not fear.
Hurricanes, and floors can be predicted and tracted allowing those in it's path to move out of it's way....the storms, tornadoes, heavy rains and floors that are carried within a hurricane, especially after they make landfall, should also be cause for concern.
Earthquakes, to me, are very scary....they seem to just happen without much, if any, warning.....not something you can necessarily prepare for
I try not to allow fear to come into the equation....when you are in fear you can't think....but I am concerned whenever I hear about any natural disaster looming.
