Louisiana is no stranger to many kinds of natural disasters. Since 1953 the state has declared 84 major disasters. Due to the large coastal area and many river systems, including Mississippi river - the largest river in the US by volume, flood remains the main threat.
Historically most of the floods were caused by hurricanes with Katrina being the most prominent one in recent history.
With almost half of all residential properties in Louisiana located in a potential flood zone, hurricane preparedness becomes a high priority.
On a lesser but still significant scale Louisiana is also exposed to tornadoes, wildfires, and even minor tectonic activity.
