Question
Indicate if the following geological hazards can be caused by earthquakes (True) or not (False).
1- materials lose coherence and act as a fluid
2- meteorite impacts
3- groundshaking combined with liquefaction reduces the strength of some slopes considerably, resulting in landslides
4- regional metamorphism
5- inundation of land in coastal areas when faulting drops land below sea level
6- giant water waves created by faulting on the sea floor or by landslides slipping into the ocean
7- fires and floods
8- volcanic ash falls
9- tornadoes
Explanation / Answer
1- materials lose coherence and act as a fluid
Answer:True
materials lose coherence and act as a fluid is a hazard.
2- meteorite impacts
Answer:False
Tsunamis are also generated fall of large size meteorites but not by earthquakes.
3- groundshaking combined with liquefaction reduces the strength of some slopes considerably, resulting in landslides
Answer: True
Soil liquefaction occurs when groundshaking, water-saturated granular material temporarily loses its strength and transforms from a solid to a liquid
4- regional metamorphism
Answer: False
Regional metamorphism is caused by large geologic processes such as mountain-building.
5- inundation of land in coastal areas when faulting drops land below sea level.
Answer: True
6- giant water waves created by faulting on the sea floor or by landslides slipping into the ocean.
Answer: True
7- fires and floods
Answer: True
Ground shaking and rupture, damage, fires and floods are hazards of earthquake.
8- volcanic ash falls
Answer: True
Most earthquakes directly beneath a volcano are caused by the movement of magma.Which produces ash fall.
9- tornadoes
Answer: False
