GEOLOGY

Detailed explanation-1: -When a tsunami reaches shore, it may appear as a rapidly rising or falling tide, a series of breaking waves, or even a tidal bore. Reefs, bays, entrances to rivers, undersea features and the slope of the beach all help to modify the tsunami as it approaches the shore.

Detailed explanation-2: -Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea.

Detailed explanation-3: -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.

Detailed explanation-4: -A tsunami is an ocean wave triggered by large earthquakes that occur near or under the ocean, volcanic eruptions, submarine landslides, or by onshore landslides in which large volumes of debris fall into the water. Learn more: Tsunamis and Tsunami Hazards.
