D FUCKING RRR Flashcards
is a feeble shaking to violent trembling of the
ground produced by the sudden displacement
of rocks or rock materials below the earthβs surface.
earthquake
generated by the sudden displacement along faults in the solid and rigid layer of the earth.
Tectonic earthquakes
earthquakes induced by rising lava or magma beneath active volcanoes
Volcanic earthquakes
of an earthquake refers to the amount of energy released, measured by the
amount of ground displacement or shaking.
Magnitude
is the strength of an earthquake as
perceived and felt by people in a certain
locality
Intensity
disruptive up-down and sideways movement or
motion experienced during an earthquake
Ground shaking
displacement on the ground due to
movement of fault
Ground rupture
is a process that transforms the behavior of a
body of sediments from that of a solid to that of a liquid when subjected to extremely
intense shaking
Liquefaction
failures in steep or
hilly slopes triggered
by an earthquake
Earthquake induced landslide
Even moderate ground
shaking can break gas
and electrical lines,
sever fuel lines, and
overturn stoves.
Fires
sea waves resulting from the disturbance of ocean floor by an earthquake
tsunami
A tsunami is a Japanese word meaning
βharbor wavesβ
The increase in wave heights associated or
during typhoons (when there are strong
winds) or tropical cyclones are called
βstorm surgesβ
are phenomena arising
from volcanic activity
that pose potential
threat to persons or
property in a given
area within a given
period of time
Volcanic hazards
are streams of molten
rock that pour or
ooze from an
erupting vent
Lava flows
are showers of
airborne fine- to
coarse-grained
volcanic particles
that fallout from the
plumes of a volcanic
eruption
Ashfall or tephra fall
is a dense, fast-
moving flow of
solidified lava
pieces, volcanic
ash, and hot gases
Pyroclastic flows and surges
is a violent type of
mudflow or debris
flow composed of a
slurry of pyroclastic
material, rocky
debris and water
Lahar
the fluid gas phase
released by active
volcanoes, both
during eruption
and quiescence
Volcanic Gases
Volcanic materials
directly ejected from
the volcanoβs vent with
force and trajectory
Ballistic projectiles
