Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these are secondary effects of an earthquake?
A
Tsunami
B
Fires
C
Ground Shaking
D
Landslides
Explanation: 

Detailed explanation-1: -Secondary earthquake environmental effects (EEE) are induced by the ground shaking and are classified into ground cracks, slope movements, dust clouds, liquefactions, hydrological anomalies, tsunamis, trees shaking and jumping stones.

Detailed explanation-2: -Primary effects of an eartquake can include the ground shaking, buildings collapsing, and the ground splitting. Secondary effects may include subsidance, tsunamis, fires, contamination of water supplies, gas leaks, and power outages.

Detailed explanation-3: -Earthquakes can trigger landslides and mudslides, especially in areas with water-soaked soils. Landslides may result in falling rocks and debris that collide with people, trees, animals, buildings and vehicles. They also can block roads and disrupt utility lines.

Detailed explanation-4: -Landslides can also sometimes cause blockages to rivers, forming quake lakes which can then, if unstabilized, unleash huge flooding on settlements downstream. Although there have not been many instances, flow-on disasters such as a flood where an earthquake occurs simultaneously can have major cascading impacts.

Detailed explanation-5: -A landslide might occur as either a primary, secondary or tertiary hazard. occur in some of the areas affected by earthquakes, volcanoes and landslides, but rarely do volcanic eruptions trigger tsunami.
