Flooding fields can help manage soil-borne pests like nematodes by creating anaerobic conditions that disrupt their life cycle.

Reforestation is a process of replanting trees in an area, reforestation is an effective way of checking floods, planting trees can reduce the height of flood by 20%.

• Earthquake is a sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust and the sudden release of energy in the Earth's lithosphere that creates seismic waves.
• A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not.
  
• Hence earthquakes recorded by a seismograph.
• So, the correct answer is 'By a seismograph'.

• A tsunami or tidal wave, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
• A tsunami can be caused due to various reasons. Among them, the most destructive Tsunamis are caused by earthquakes 
  
• Hence a tsunami can be caused due to Underwater earthquake.
  
• So, the correct answer is 'Underwater earthquake'.

Earthquakes are caused by the sudden release of accumulated energy when tectonic plates, which have been locked or jammed, finally slip past each other. This release of stress generates seismic waves.

• A tsunami or tidal wave, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
• Mangroves are forests of salt-tolerant trees and shrubs that grow in the shallow tidal waters of estuaries and coastal areas in tropical regions. Mangroves protect shorelines from damaging storm and hurricane winds and tsunami.
• A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Coral reefs provide protection to our coasts from the tsunami, storms, and floods.
  
• Hence Coral Reefs and Mangroves can act as natural barriers to control Tsunami.
• So, the correct answer is 'Both A and B'.

The Japanese word Tsunami is composed of 'tsu', meaning harbor, and 'nami', meaning wave. It literally translates to harbor wave.

The 2004 Indian Ocean earthquake and tsunami occurred on December 26, 2004, and is recognized as one of the deadliest natural disasters in recorded history.

Slip erosion is a common term used to describe the downward movement of soil and rock, which is scientifically known as a landslide.

Floods lead to soil erosion (A-2), Earthquakes can trigger landslides (B-3), and Droughts cause food scarcity (C-1).
