What is an earthquake?

In simple definition an earthquake is when an event whether it be natural or human induced causes the ground to shake.

WHY EARTHQUAKE’S OCCUR

An earthquake is like a snap of your fingers. When you first press your fingers together and sideways, friction prevents them from moving. The same thing happens with the friction along an earthquake fault line, a "crack" in the earth's crust. Pressure builds until—snap!—.

Fresh water supplies may be destroyed or disrupted. Food supplies will most likely be unavailable. The potential for disease, post-traumatic stress disorder, grief, starvation, and injuries will make the post-tsunami period nearly as perilous as the tsunami itself.

Personal Issues

Solutions1. Learn about the potential danger in advance. Meaning your

home, school, and work. Where are you located. See if you area is proned for Tsunamis.

2. Prepare in advance. Assemble some type of emergency pack. (First aid kit, rain coat, some food, a radio if you can).

3. Be the smart one in your community. If it doesn’t have a community tsunami readiness training with plans of evacuation, start one!

4. Heed natural warning signs such as earthquakes, which depending on size of earthquake should be your first cause of alarm. A rapid rise and fall of coastal waters. Animal behavior changes.

5. Listen for community and government warnings.6. If you get caught in the tsunami grab for something that floats if

possible. 7. Abandon belongings. Remember Save lives, not possessions.8. If you survive, keep away until the “all clear” signals is passed.

Their can be a following of other waves after the first wave impacts.
