Cars and trucks were everywhere, thrown around like toys. House ruins were everywhere. There were tables, chairs, and all kinds of furnitures scattered around making piles of ruins. People were trying to search for their belongings that was still in good condition. Sounds of people digging the piles to look for their things. Roofs were still falling apart. But some houses were lucky to still stand, even though it wasn’t a whole anymore. Babies crying, dogs were barking. Everybody was really scared because they didn’t know where they’ll live. All they’re belongings are ruined and they didn’t have anything anymore. The dusts from houses covered my skin. It was really terrifying view.

Bam Earthquake

Bam is a city located in Iran. And Iran is the country bordered by Turkey, Armenia, Azerbaijan, Turkmenistan, Afghanistan, and Pakistan. The earthquake occurred because the eurasian plate and the arabian plate squashed Iranian plate making the plate break and crash to each other. California, USA is also at high risk of earthquakes. Builders are forced to make buildings earthquake-proof.

Comparing Two Earthquakes
Location Bam, Iran Northridge, USA
Magnitude 6.5 (Richter Scale) 6.7 (Richter Scale)
% Of population killed 43% 9.5%
% Of buildings damaged 70% 20%
Are strict rules in force for seismic-proof buildings? There are no strict rules for seismic-proof buildings and they make their houses using mud bricks that are easy to break. Rules there are very strict and all the buildings are seismic-proof buildings.

 

But why do people continue to live in natural disaster areas? Some people just don’t have enough money to move to another area that’s safer and some people just don’t care about they’re surroundings. There are also people that have good jobs and good way of life in that area so they don’t want to move. People that live in big cities don’t know where to move to. And in Tokyo and California, where the technology is really good, they rely on the technology and they safe.

Earthquakes

 

Step 1: Pressure build up because of the powerful forces pushing.

Step 2: Too much pressure, mass of rock gives way and push upwards.

Step 3: The stored energy released in waves called seismic waves.

Step 4: The focus point is where the seismic waves started.The epicenter is the point above on the earth’s crust.

Step 5: Aftershocks are small earthquakes that happens after the rock set into the right place.

 

How Big?

  • We use seismometers to measure the waves on a graph.
  • Scientists tell how big it is from the graph.
  • And the energy from an earthquake has is called its magnitude.
  • We use Richter scale to show it. (example below)

Richter Scale:

1

You wouldn’t notice this

2

30 times more energy than 1

3

30 times more energy than 2 and so on

4

5

Windows might break

6

Damages buildings

7

Major catastrophe

8

9

10

(Biggest ever recorded 9,5)

 

  • On the scale, with only 1 number difference, it means it’s shaking 10 times harder. And that means there is about 30 times more energy is released.
