A

Seismologist

27
Q

is the instrument used to record seismic waves

A

-Seismograph

28
Q

is the record of the ground shaking

A

Seismogram

29
Q

is the place inside Earth’s crust where an earthquake originates

A

focus

30
Q

the location directly above where the earthquake starts

A

epicenter

31
Q

A fracture in the rocks that make up the Earth’s crust

A

Fault

32
Q

As the distance from the focus and epicenter increases, the shaking of the ground decreases

wala basa lang

A

-

33
Q

EARTHQUAKE CAN BE DESCRIBED BY:

A

MAGNITUDE and INTENSITY

34
Q

estimate of the amount of energy released at the focus or origin of the earthquake (Arabic numerals)

A

Magnitude

35
Q

is used for the quantitative measure of the earthquake’s magnitude

A

Richter scale

36
Q

refers to the degree of shaking or the severity of its effects on the earth’s surface.

A

Intensity

37
Q

What are the Earthquake hazards? (5)

A
  • Ground Shaking
  • Ground Rupture
  • Liquefaction
  • Tsunami
  • Fire
38
Q
  • Up down and lateral movement or vibration of the ground caused by the passage of body and surface seismic waves
  • Buildings and other structures that can’t withstand ground shaking can have damages, can be destroyed or can collapse
  • can cause landslide and liquefaction
A

Ground shaking

39
Q
  • The offset or deformation of the land surface due to movement of the fault
  • this geologic phenomenon commonly happens in shallow earthquakes
  • ground cracks
  • structures present across fault zones can collapse
A

Ground rupture

40
Q
  • it happens when ground shaking due to moderate or intense earthquake results to the mixing or body of sediments (sand or soil) and ground water, and as a consequence, the ground becomes soft and could no longer support structures that will eventually sink or tilt
  • it can lead to ground failure
A

Liquefaction

41
Q
  • means harbor waves in japanese, is a series of waves generated by an earthquake that occurs below or near ocean floor
  • rapid, violent flooding in communities near coastal areas
A

Tsunami

42
Q

are caused by gravitational force between the earth and the moon

A

tidal waves

43
Q

the heightening of sea level that occurs during typhoons or hurricanes

A

Storm surge

44
Q

is associared with broken gas pipes and damaged electrical lines because of damages caused by ground shaking to buildings and other infrastructures

A

Fire

45
Q

TYPES OF TSUNAMI

A

Local and Far field or Distant

46
Q

tsunami generated within a hundred kilometers from the source and is confined to coasts. Caused by earthquakes, landslides or a pyroclastic flow

A

Local

47
Q

tsunami waves that can travel from 1 to 24 hours before reaching the coastlines of the nearby countries

A

Far field or Distant

48
Q

Signs of an Impending Tsunami

A

1.** If earthquake occurs** in the coastal region and it originated from the oceanic crust, a possible tsunami can take place
2. Rapid fall in sea level may happen as the ocean water withdraws from the coastline
3. Unusual** roaring sound** which can be an approaching tsunami

49
Q

A map that shows areas that area vulnerable or at risk to a specific hazard.

A

HAZARD MAP

50
Q

There is a separate map for each kind of hazard.

basa lang

A

Example is flood hazard map

51
Q

USES OF HAZARD MAP

A
  • Are basis for risk reduction and hazard protection measures
  • Give significant information for emergency planning
  • Show potential risk to the communities, which raises their awareness and readiness
52
Q

It is a vent, hill or mountain from which hot and molten rocks, rock fragments, and gaseous materials have been ejected

A

VOLCANO

53
Q

is molten or hot liquid rock in the Earth’s mantle

A

MAGMA

54
Q

magma or molten rock that reached the Earth’s surface

A

LAVA

55
Q

VOLCANO HAZARDS (6)

A
  • Lava flows
  • Pyroclastic fall
  • Pyroclastic flow
  • Lahar
  • Volcanic gases
  • Ballistic projectiles
56
Q

are rivers of incandescent molten rock or lava that erupted from a crater or fissure and moves downslope or away from an eruption vent.

A

Lava flow

57
Q
  • is the least viscous that can flow up to tens of kilometers from the erupting vent
  • 1000 - 2000 degrees Celsius
A

Basaltic Lava

58
Q
  • it is moderately viscous,it can flow a few kilometers per hour
  • 800 - 1000 degrees Celsius
A

Andesitic Lava

59
Q
  • most viscous and forms a lava dome as it flows at the slope ofthe ground
  • 650 - 800 degrees Celsius
A

Ryolitic Lava

60
Q

occurs when pyroclastic fragments of rocks or tephra are ejected in a great distance and propelled through the atmosphere

A

Pyroclastic Fall

61
Q

is a mixture of pyroclastic fragments, specifically how lava blocks, pumice
and ash, and hot volcanic gases

A

Pyroclastic Flow

62
Q

it is a mudflow or debris flow, a mixture of pyroclastic materials and water

A

Lahar

63
Q

are gases that are released to the atmosphere during eruptions includes water vapor, carbon dioxide, carbon monoxide, sulfur dioxide, hydrogen sulfide, hydrogen chloride and hydrogen fluoride.

A

Volcanic Gases
