Question 1

shaking of the surface of the earth

Answer 1

earthquake

Question 2

frequent in the philippines because of Pacific ring of fire

Answer 2

earthquake

Question 3

Effects of earthquake

Answer 3

Primary, secondary

Question 4

permanent features an earthquake can bring out

Answer 4

primary

Question 5

happen when ground movement results to other types of destruction

Answer 5

secondary effects

Question 6

are measured at the epicenter

Answer 6

earthquake magnitude

Question 7

the point on the earth’s surface directly above the hypocenter

Answer 7

epicenter

Question 8

it measured on one of the scales based on work of charles richter

Answer 8

earthquake magnitude

Question 9

Amount of loss and destruction depends upon factors

Answer 9

Duration of shaking, distance from the fault, local condition, population density, building quality

Question 10

is measure of the level of ground shaking that correlates more directly with hazard impact than does magnitude

Answer 10

intensity

Question 11

it is estimated on the modified mercalli scale which allocates a numerical value of observation of the temblor and the extent of physical damage

Answer 11

Earthquake intensity

Question 12

Earthquake intensity is measured on this scale which allocated a numerical value of observation of the temblor

Answer 12

Modified mercalli scale

Question 13

Is caused by the passage of seismic waves, forms of energy that travel through different layers of earth caused by vibration or movement

Answer 13

ground shaking

Question 14

this occurs when ground movement happens on a fault line and breaks through the surface

Answer 14

ground rupture

Question 15

follows preexisting faults known as zones of weakness

Answer 15

fault rupture

Question 16

this occurs when seismic shaking causes loose materials in the soil to mix with the ground water or soil saturated with water

Answer 16

liquefaction

Question 17

the soil behaves like a quicksand that has lost its strength to hold and support objects on the top of it

Answer 17

liquefaction

Question 18

subsidence is the lowering of the land due to various causes, one of which is the earthquake on a fault line

Answer 18

earthquake induced ground subsidence

Question 19

it is a japanese word that means “harbor wave”

Answer 19

tsunami

Question 20

what is the meaning of tsunami

Answer 20

harbor wave

Question 21

it is coined as harbor wave because of the destructive effects

Answer 21

tsunami

Question 22

series of waves that are generated by a sudden displacement on the floor area

Answer 22

tsunami

Question 23

landslide may happen during or after an earthquake when a weakened section of land falls off primarily due to gravity

Answer 23

earthquake induced landslide

Question 24

is an instrument used to measure movements in earth’s surface

Answer 24

seismometer

Question 25

can detect vibrations from seismic waves generated by earthquake and volcanic eruptions

Answer 25

seismometer
