2. 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.

3. 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!—.

6. What are some
problems?
Who is affected and
what are some
problems, go hand in
hand.

7. The cost in damages are great from
human lives as well as animal lives, to
communities and businesses.

8. Solutions
Before
During
1. Secure your space
2. Plan to be safe (have some sort of plan
already developed, communication and
such.
3. Organize disaster supplies (convenient Places)
4. Minimize Financial Hardships (Strengthen
home, consider insurance)
1. Drop
2. Cover
3. Hold on
After
1. If not injured help those that are. Evacuate from Tsunami Zones.
2. Re-connect with your community and restore what was
destroyed.

11. Tsunami

12. Indonesian Tsunami

13. 1720 feet tall in
Lituya Bay, Alaska
Landsat Image 40 years later. Vegetation and
Soil were completely removed.
Located 7 miles from the actual source.

14. Personal Issues
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.

15. Solutions
1. 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.
