Earthquakes

What are earthquakes? Earthquakes are devastating natural disasters. They can shake, break, and split the ground apart. Earthquakes can also cause massive damage. Here is some information about how much damage earthquakes do, how to stay safe in one, first hand accounts, and more.

Effects

How much damage can earthquakes do? Earthquakes size and damage are based on the Richter scale. This scale ranges from 0.1 to 10.0. According to the article “What are Earthquakes,” by dummies, earthquakes that are about a 4.0 or less on the Richter scale only occur in small areas, let alone even be felt. 4.0s to 4.9s cover larger areas and are noticeable but still have a great lack in damage. You can really start actually start to see some damage with a 5.0 earthquake starting with poorly constructed buildings. Also, if an earthquake spawns near the ocean, a tsunami can occur. Now that you know that earthquakes have the power to tear down buildings, split the ground in two (or more), and even summon tsunamis, you should probably read about safety tips, some earthquake history, and more.

Earthquake History and Safety

Now you'll read about why when and where earthquakes happen safety tips and history. According to KQED Quest and Learning junction earthquakes usually happen because rocks underground suddenly break along the fault, this sudden release of energy causes the seismic waves that make the ground shake.

There are four types of waves the first wave that happens is called the P wave it is the fastest and least effective. Next is the S wave it is slower but more effective than the P wave. After that is the Love waves and R waves they are the two surface waves. L waves do a lot more damage than P or S waves. Lastly the R wave the last and most powerful wave that moves both vertical and horizontal unlike any of the other waves.

Most of the world's earthquakes happen in the Ring of Fire. The ring of fire is an area where earthquakes usually happen because it is associated with trenches, volcanic arcs, and volcanic belts or plate movement.

Now to learn about the history of earthquakes according to earthquakes By Seymour Simon . Once on September 19, 1985 in Mexico city a major earthquake struck, and over 10,000 people died, and 100+ homes stores, hospitals, hotels, schools, and business buildings. But luckily little damage to neighboring buildings.

Next you'll read about tips and how to stay safe.

  1. always have a fire extinguisher.
  2. Learn first aid
  3. Learn how to turn off gas, electricity, and water
  4. Make plans where to meet after a earthquake
  5. Make sure there aren't heavy things on shelf
  6. Anchor furniture
  7. Learn earthquake plans a school or work building
  8. What to do during an earthquake
  9. Stay calm
  10. Stay away from glass
  11. Go under heavy furniture if indoors if not stay in open area away from powerlines and poles if in a car, stop the car and stay inside the car until the earthquake stops
  12. Don't use elevators

What to do after a earthquake

  1. Stay away from damaged areas
  2. Look for injuries

Lastly, stay away from damaged buildings, now you know where when why some history and tips on how to stay safe.

EARTHQUAKE!!!

Have you ever wondered what it's like to be in an earthquake? The following is a first hand account. This is what it's like to be in an earthquake. This is what Christopher Stent said “I was working from home. I was in the square right outside the Cathedral the Whole front fell down and there were still people in side as it fell. A woman grabbed on to me so she wouldn't fall over. Columbo street was just a mess with water pouring out of the ground.” That was a 1st hand account of the Christ church, New Zealand earthquake in 2011.

Conclution

Now that you know about what earthquakes can do, some earthquake history, how to stay safe in an earthquake, and even some first hand accounts, if your ever in an earthquake you'll know exactly what we're talking about! Thanks for reading!
