Multiple Choice

Sea waves resulting from the disturbance of the ocean floor by an earthquake

• .Liquefaction

• Ground Rupture

• Tsunami

Tsunami

This a series of giant sea waves commonly generated by under-the-sea earthquakes whose heights could be greater than 5 meters.

Multiple Choice

Tsunami and storm surge are the same?

• TRUE

• FALSE

TSUNAMI VERSUS STORM SURGE

A tsunami is a Japanese word meaning “harbor waves”. A tsunami is commonly generated by disturbances associated with earthquakes occurring below or near the ocean floor.

storm surges are wind-generated waves on the surface of the sea. 

Signs of an impending Tsunami

• Strong Shaking, Earthquake

• Sea will withdraw. Rapid lowering of sea level or noticeable rise and fall of coastal water

• The unusual rumbling sound of approaching waves

Multiple Choice

This is a displacement on the ground due to movement of fault.

• Ground Rupture

• Liquefaction

• Tsunami

Ground Rupture

Some may experience superficial cracks because of ground failure.

Multiple Choice

It 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.

• Ground Rupture

• Liquefaction

• Ground Shaking

Liquefaction

As a result, any heavy load on top of the sediment body will either sink or tilt as the sediment could no longer hold the load.
