Match the Earthquake hazards:
ground shaking
landslides
liquefaction
surface rupture
tsunami
fire
flooding
Earthquake hazards are those that are caused by the primary hazards, and may often be more catastrophic:
Secondary hazards
Tertiary hazards
Tornadoes
Seismic waves
Liquefaction
a process by which water-saturated sediment temporarily loses strength and acts as a fluid. This effect can be caused by earthquake shaking.
(a)
Giant waves caused by earthquakes or volcanic eruptions under the sea.
(a)
What type of plate boundary is associated with the largest earthquakes?
Convergent
Divergent
Transform
What type of fault is associated with the largest earthquakes?
Reverse (thrust)
Normal
Strike-slip
These may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters.
tsunami waves
fires
liquefaction
surface waves
Which building material would be best for Earthquake damage mitigation:
Wood
Steel
Brick
Stone
Adobe
Why are wood and steel better materials for mitigating Earthquake damage:
A secondary earthquake hazard that occurs because of burst gas lines, candles and lamps toppling over:
(a)
In San Francisco, 1906, up to 90% of building damage, after the earthquake, was attributed to:
(a)
Which of the following are the three (3) large zones of Earthquakes:
Circum-Pacific seismic belt
Alpine-Himalayan belt
Mid-Atlantic Ridge
New Madrid Fault
Caribbean island Fault system
A region where two tectonic plates are spreading apart (a divergent plate boundary), deep underwater and far from human development, except for Iceland.
Circum-Pacific seismic belt
Alpine-Himalayan belt
Mid-Atlantic Ridge
New Madrid Fault
Caribbean island Fault system
Extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. It accounts for about 17 percent of the world's largest earthquakes, including some of the most destructive
Circum-Pacific seismic belt
Alpine-Himalayan belt
Mid-Atlantic Ridge
New Madrid Fault
Caribbean island Fault system
This belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking (or subducting) beneath another plate.
circum-Pacific seismic belt
San Andreas fault
Mid-Atlantic Ridge
Alpine-Himalayan belt
The circum-Pacific seismic belt is also known as:
The ring of fire
The Rocky mountains
The Appalachian mountains
Helms Deep
Shadows of Mordor
Describe liquefaction:
Which type of ground would best mitigate the damage from Earthquakes:
Solid bedrock
Poorly consolidated sediment
Water-saturated sand and mud
Which type of ground would most readily lead to liquefaction:
Solid bedrock
Poorly consolidated sediment
Water-saturated sand and mud
