DRR EARTHQUAKE QUIZ Flashcards
(26 cards)
AGREE OR DISAGREE
Most earthquake hazards in areas closer to the fault or earthquake-generating structure more likely to experience the brunt of liquefaction.
AGREE
AGREE OR DISAGREE
Denser infrastructure or more buildings in a certain area contributes to the weight of the sediments.
AGREE
AGREE OR DIASGREE
In the case for Metro Manila, liquefaction susceptibility maps have been prepared by PAGASA to monitor potential liquefaction sites and to disseminate this information to the public.
DISAGREE
AGREE OR DISAGREE
Landslides can be triggered by factors such as heavy or prolonged rain, over steepened slopes, removal of vegetation, and earthquakes.
AGREE
AGREE OR DIASGREE
For an earthquake to induce landslides, the following factors must be considered: the strength of the earthquake, the distance from the fault, topography, climate, and the characteristics of the rock or soil.
AGREE
AGREE OR DISAGREE
Loose, unconsolidated materials are more likely to fall in the event of a landslide than indurated rock.
DISAGREE
AGREE OR DIASGREE
Regional tsunamis
are from a nearby source.
DISAGREE
AGREE OR DIASGREE
When an earthquake occurs beneath the sea, the water above the affected area moves upward and produces tsunamis.
AGREE
AGREE OR DISAGREE
A tsunami that is only hundreds of meters offshore can grow up to hundreds of kilometers.
DISAGREE
The sudden and rapid movement of large volumes of rock along fractures on the surface of the earth.
FAULTS
Seismic waves that travel through the interior of the earth.
BODY WAVES
Waves that are trapped near the surface.
SURFACE WAVES
Surface waves that have a horizontal motion perpendicular to the direction they are traveling.
LOVE WAVES
A set of rules that set standards on the construction of buildings.
building code
The visible breaking and displacement of the Earth’s surface along the
trace of a fault.
Ground Rupture
If the block
opposite you when looking across a fault moves to the left.
Sinistral
Vertical or near-vertical faults that displace rock horizontally.
Strike-slip Faults
Cause vertical (normal or reverse) movement.
Dip-slip Faults
If the block moves to the right
Dextral
Occurs when the ground loses stiffness and behaves like liquid in response to
earthquakes.
Liquefaction
The downslope movement of rocks
or sediments under the influence of gravity.
Mass Wasting
Wherein the sediments are compressed and fluids in the pore spaces are
squeezed out.
Compaction
A series of waves generated by large-scale displacements of water which are
usually triggered by earthquakes or major submarine landslides.
Tsunami
