GEOLOGY

Detailed explanation-1: -There are three factors of destructions from tsunamis: inundation, wave impact on structures, and erosion. Strong, tsunami-induced currents lead to the erosion of foundations and the collapse of bridges and seawalls.

Detailed explanation-2: -In addition to loss of life and mass injuries, other potential impacts include damage to and destruction of homes and businesses, ports and harbors, cultural resources, utilities, and critical infrastructure and facilities. There may be loss of access to basic services such as power, sewer, and water.

Detailed explanation-3: -Tsunamis may create significant flooding in coastal locations. A large tsunami might inundate areas many kilometres inland. The waves that impact the shore first, followed by floods inland, can inflict significant infrastructure damage (including houses and roads), land, agriculture, and livestock.

Detailed explanation-4: -People who live in floodplains or non-resistant buildings, or lack warning systems and awareness of flooding hazard, are most vulnerable to floods.

Detailed explanation-5: -A tsunami is a series of enormous waves created by an underwater disturbance usually associated with earthquakes occurring below or near the ocean. Volcanic eruptions, submarine landslides, and coastal rock falls can also generate a tsunami, as can a large asteroid impacting the ocean.
