FC: Earthquakes | The "dragons" of the earth | By Alyssa Aguilar. Arushi Garg, and Trisha Karnik | Challenge

1: When it strikes, what would you do? | A. Panic B. Hide C. Drop, Cover, and Hold on D. Duck and cover | Answer: C and D | On with the presentation. Just sit back and hold on...

2: How are they caused? | The top of the mantle and the crust of the earth is like a big puzzle making up the surface of the earth. The pieces are named tectonic plates. The edges of the plates are called plate boundaries.

3: Faults are what make up the plate boundaries. The plate boundaries sometimes get stuck, because they are very rough. Tectonic plates move around, sliding past each other, so, when the plate boundaries get stuck, the rest of the plate moves.

4: While it is moving, energy is being stored. Then, the edge gets unstuck and the energy is all released on the faults. They can be released as either S waves (seismic waves) P waves (primary waves). P waves are a lot faster than S waves.

5: What should you do when it strikes? | If you are outside: If you can, move to an area free of trees, signs, or hazardous objects. Avoid any falling objects or anything to big that could fall.

6: If you are inside: Stop, drop, and hold on. If you are in bed, stay there and duck and cover with your pillow over your head. | If you are driving: Find the safest and closest parking spot, set the parking brake, and wait in the car until the shaking stops. If you are on the highway, pull over on the closest road, and wait for the shaking to stop

7: If you are somewhere high (high-rise): Drop, cover, and hold on. Avoid any broken glass and other dangerous objects that may hurt you. | Where do they happen? | They strike mostly around the Pacific ocean and the countries on it.

8: Mostly countries like: Chile, countries up Central America, west coast of the U.S., Mexico, southern Alaska, Aleutian islands to Japan, Philippines, New Guinea, islands of the South West Pacific, and New Zealand. | Types of Damage | It depends on the earthquake. If it is a small earthquake, probably just small things knocked of a table, or framed

9: pictures knocked off walls. But in a big one, it could be buildings broken, signs, trees, power lines, all knocked down, and tons of major damage.

10: Effects on the people and economy | They can also knock down gasoline stations or spread fires, causing more damage and injuries. The more damage, the more money put in to rebuild the city. | Earthquakes cause tons of major damage, and sometimes the shaking can cause tsunamis.

11: For the people, they need to pay for healing injuries, and the damage of their houses. Lives can sometimes be taken. The economy, needs to spend their money on rebuilding buildings, and if they cannot afford it, the city may end up like the city Managua of Nicaragua. | Managua still looked the same fifteen years later from their "earthquake attack."

12: What to do before it | To avoid being in too much danger when an earthquake strikes, fix anything that may fall easily in shaking, such as loose windows or almost-falling-off doors. Practice drop, cover, and roll, and identify places to cover. Secure things that could fall and easily hurt someone.

13: Also secure things that are very valuable and cost a big amount of money. | Emergency Kit | Keep one at home and in car: | Medicines, prescriptions list, doctor's contact info.

14: First aid kit and handbook (if needed) | Examination gloves (non latex would be best) | Dust mask | Spare glasses, or contact lenses, and cleaning solution for glasses | Bottled water | Whistle, so to warn rescuers where you are | Emergency cash | Road maps | Phone numbers of people out-of-area listed down

15: Snack foods (best if high in calories) | Flashlight with new batteries (working too) | Small items that keep you comfortable (small toys, journal, games, etc. | Special provisions for pets, elderly, and small children in family | Copies of identification items (drivers license, ID card, etc. | THANK YOU!
