Tsunamis are among Earth's rarest hazards. But, even though tsunamis do not occur very often, and most are small and nondestructive, they pose a major threat to coastal communities, particularly in the Pacific. A tsunami can strike any ocean coast at any time. There is no season for tsunamis. We cannot predict where, when or how destructive the next tsunami will be. However, while tsunamis cannot be prevented, there are things you can do before, during and after a tsunami that could save your life and the lives of your family and friends. Read these pages to learn about tsunamis and what you can do to keep yourself and your loved ones safe in the event of a tsunami.
A tsunami is one the most powerful and destructive natural forces. It is a series of waves (not just one) caused by a large and sudden disturbance of the sea. Tsunami waves radiate outward in all directions from the disturbance and can move across entire ocean basins. Most tsunamis are caused by undersea earthquakes, but can also be caused by landslides, volcanic activity, certain weather-related phenomena and meteorites. Not all earthquakes cause tsunamis.

An earthquake is a sudden, rapid shaking of the earth caused by the breaking and shifting of rock beneath the earth’s surface. Earthquakes strike suddenly, without warning, and they can occur at any time of the year, day or night. Forty five states and territories in the United States are at moderate to very high risk of earthquakes, and they are located in every region of the country. Earthquakes strike suddenly, violently and without warning. Identifying potential hazards ahead of time and advance planning can reduce the dangers of serious injury or loss of life from an earthquake.
The actual movement of the ground in an earthquake is seldom the direct cause of death or injury. Most casualties result from falling objects and debris because the shocks can shake, damage, or demolish buildings, bridges, and other man-made structures. Earthquakes can also trigger landslides and generate huge ocean waves called tsunamis. Both of these can cause great damage and loss of life.

It's time to talk about what we can expect when the New Madrid rips and tears and you might be asking what is the New Madrid and why do I need to know about it? Well, it might possibly effect you right where you live so let's talk about that.
The New Madrid fault line essentially follows the Mississippi River from Illinois to Arkansas. The last major adjustment of this seismic zone was way back in December, 1811 and since science says this happens about every 200 years we're way overdue for another big adjustment and we have a lot of ground to cover.

Earthquake Action Plan
The most important thing you can do during an earthquake is to remain calm. By doing this, you will be in a better position to assess your situation and instill confidence in those around you. Think through the consequences of any actions you take. Try to calm and reassure others. Stay as safe as possible during an earthquake. Be aware that some earthquakes are actually foreshocks and a larger earthquake might occur. Minimize your movements to a few steps to a nearby safe place and if you are indoors, stay there until the shaking has stopped and you are sure exiting is safe.
