Answer 2

The exact statement regarding earthquakes is- 3) The earth is constantly vibrating less and more.

3) Correct option- The earth is constantly vibrating less and more

• The basic characteristic of an earthquake is the shaking or vibration of the earth's surface.
• Movements in the earth's outermost layer are causing these vibrations or tremors.
• Hence, this option regarding constant vibrations which can be high or low, is correct.

1) Incorrect option- The number of catastrophic earthquakes is much higher than the number of mild earthquakes on Earth.

• Mostly the earthquakes that occur on the earth are mild.
• There have been a good few numbers of catastrophic earthquakes like the 1960 Chilean earthquake, the Good Friday earthquake in Alaska (1964),  the 2004 Indian Ocean earthquake, etc.
• We cannot feel most of the mild earthquakes.

2) Incorrect option- Damage to the epicenter of the earthquake the proportion is low.

• Earthquakes do not cause damage to the epicenter.
• Instead, earthquakes are caused due to the movement of tectonic plates or volcanic activity, nuclear tests, etc.

4) Incorrect option- Earthquakes stabilize groundwater.​

• Earthquakes do not stabilize groundwater.
• The permeability of the aquifers in the affected regions might increase which in turn might increase the flow of groundwater.

Hence, the correct answer is option 3- The earth is constantly vibrating less and more.
