Upon making contact with the shore, tsunamis can severely alter the coastal landscape through rapid erosion and deposition of sediment. High wave energy may transport coastal vegetation and marine debris and leave in place unstable barren dunes susceptible to further erosion.

Tsunami waves and the receding water are very destructive to structures in the run-up zone. The areas close to the coast are flooded with sea water, damaging the infrastructure such as sewage and fresh water supplies for drinking.

Economy Immediately following a tsunami disaster, many businesses will be unable to trade because of destruction to premises, stock, machinery, facilities, transport networks, supplies and loss of staff.

Tsunamis can have a devastating effect on human lives. They can destroy homes, change landscapes, hurt economies, spread disease and kill people.

Natural disasters cause destruction of property, loss of financial resources, and personal injury or illness. The loss of resources, security and access to shelter can lead to massive population migrations in lesser-developed countries.

In a disaster, you face the danger of death or physical injury. You may also lose your home, possessions, and community. Such stressors place you at risk for emotional and physical health problems. Stress reactions after a disaster look very much like the common reactions seen after any type of trauma.

In fact, some economists argue that despite the widespread destruction they leave behind, hurricanes, earthquakes, floods, volcanic eruptions and ice storms can spur economic growth. Rebuilding efforts provide a short-term boost by attracting resources to the region, economists say.

This finding suggests that after a flood, damaged production capabilities are offset by increased investments in assets and increased labor. Overall, these empirical studies suggest that the indirect effects of natural disasters significantly reduce economic growth, especially in low-income countries.

1. Disasters increase scarcity and reduce the output of economies. In simplest terms, inputs are necessary for outputs; fewer inputs means fewer outputs. When a disaster damages or destroys resources – whether labor, capital, or natural resources – total production in the economy must fall.

Economic rebuilding after a disaster never completely recovers what was lost and does not return communities to a “normal” state that existed before. There is often a “new normal”, as societies and economies are forever altered.

Keep them at a higher level, protected from flood damage. Ensure that your family has an emergency kit and plan….If a storm surge is forecast

1. Check supplies including medications, radio, flashlight and batteries.
2. You may have to evacuate.
3. Make sure the basement windows are closed.

Cyclone Amphan is classified as one of the most powerful, deadly tropical cyclones to ever impact Bangladesh and India. It was categorized as a category 5 hurricane and the havoc it wreaked was devastating.
