Earthquakes and Faults

Which government agency is responsible for studying the movements of faults and earthquakes?

• DOH

• DepEd

• PAGASA

• PHIVOLCS

Which of the following describes a fault?

• An energy released from the inside of the Earth.

• A movement in the Earth’s crust.

• A break in the Earth’s crust.

• A rock layer.

Which of the following refers to the type of fault in which two blocks slide horizontally past each other in the opposite direction?

• strike-slip fault

• reverse fault

• normal fault

• landslide

How do faults produce earthquakes?

• Energy from inside the Earth makes the ground move, once friction is overcome, a fault slips producing an earthquake.

• Rock materials from underneath go out along faults produces earthquakes

• Magma spreads beneath the rock layers producing faults.

• Tectonic plates collide producing earthquakes.

How can you relate fault movements with earthquakes?

• Every time there is an earthquake this all due to fault movements.

• Every time there is an earthquake, rock layers move causing faults to move as well.

• Every time fault moves and friction between rocks is overcome this will result in an earthquake.

• Every time fault moves even though friction between rocks has not overcome, this will result in an earthquake.

Why is it that not all movements along faults produce earthquakes?

• It is because the energy of the Earth that causes the rocks to move is very strong enough.

• It is because the friction between rocks was not overcome by the energy of the Earth.

• It is because there is no friction present between the rocks.

• It is because the layers of rocks were not broken.

Fault movement is always associated with earthquakes. Arrange the following events how fault movements generate earthquakes. I. Once friction is overcome, the rocks suddenly slip. II. Ground suddenly moves and an earthquake occurs. III. Energy from inside the Earth is necessary to make the ground move. IV. The rocks are stuck together due to friction.

• I, II, III, IV

• II, IV, I, III

• III, IV, I, II

• IV, II, I, III

For instance, your house is near a fault, which of the following are you going to consider doing?

• inform your parents about it and evacuate immediately

• inform the PHIVOLCS to monitor your house daily

• tell your parents to construct a big house

• take a selfie of the fault
