Natural disasters are the most frequent type of disaster, affecting millions of people every year. They can result in significant disruption of everyday life.

Knowing the types of potential natural disasters where you live, work, and vacation is the first step in being prepared. 

Some of the things you can do to prepare for the unexpected, such as assembling a supply kit and developing a family emergency plan, are the same for all types of disasters. However each emergency is unique and knowing the actions to take for each threat will impact the specific decisions and preparations you make.

Receiving Emergency Alerts  will help you to recognize an impending disaster. Knowing what to do to protect yourself and your family will help you take effective steps to prepare beforehand and aid recovery after the event.
