EARTHQUAKE,TYPHOON,METEORS 8

During a fault movement, Which figure show a friction is overcome, rock snap straight, releasing energy in form of earthquake?

Which of the following figures illustrates normal fault?

Where is the epicenter located in the illustration?

• 1

• 2

• 3

• D

Which point is closest to the epicenter?

• Point A

• Point B

• Points A and B

• Points B and C

How will you describe the movement of fault in this illustration?

• moving sideways

• pulling the sides apart

• pushing the sides together

• moving in vertical direction

How do faults produce earthquakes?

• Once friction is overcome, a fault slip produces earthquake.

• Molten rock materials accumulate and go out along a fault.

• Tectonic plates collide forming a volcano and causing earthquake.

• Magma and lava cause the ground to move producing earthquake.

What happens to the rocks in a fault slip?

• They stick together.

• They slide past each other.

• There is no movement at all.

• They suddenly slip and generate earthquake.

On July 16, 1990, a strong earthquake with a magnitude of 7.8 hit Luzon and its epicenter is located in Nueva Ecija where a lot of buildings and other structures were either damaged or destroyed. What would likely happen to Nueva Ejica as the earthquake hit them?

• People within the area organized a party for celebration.

• Buildings and houses were repainted.

• Lots of people had passed away, properties and infrastructures were damaged.

• Nothing happen.
