This world is full of unpredictable events.  Weather forcasters, geologists and news reporters do their best to give us advance warning of impending disasters, but sometimes disaster hits without warning.  Sometimes, even with advance warning, it is so much worse than we could have even predicted.  Being prepared to take care of yourself for up to seven days after a disaster hits is your best chance of survival.  Familiarizing yourself with the various natural and man-made disasters we may face is part of getting prepared.
