Detailed explanation-1: -Tsunamis are among the most infrequent of Earth’s natural hazards. Each year, there are approximately two tsunamis that cause damage near their source. Tsunamis that cause damage or deaths on distant shores (more than 1, 000 kilometers, 620 miles, away) occur about twice per decade.
Detailed explanation-2: -Tsunami is a series of large waves caused by a huge displacement of water in oceans or seas. This is caused due to earthquake or volcanic eruptions underwater. It is a natural disaster which causes a vast damage to human life. Q.
Detailed explanation-3: -Marine hazards, such as storm surges, tsunamis or biohazards, can be devastating for the coasts and their communities. They can also have lasting and damaging effects on the coastal landscape, causing long-term coastal erosion, and on marine ecosystems.
Detailed explanation-4: -Flood waters can pose health risks such as contaminated water and food supplies. Loss of shelter leaves people vulnerable to insect exposure, heat, and other environmental hazards. The majority of deaths associated with tsunamis are related to drownings, but traumatic injuries are also a primary concern.
