how does tsunamis affect the Earth?

Answer 1

Tsunami is an unusually large sea wave produced by a seaquake or undersea volcanic eruption.

These phenomena rapidly displace large volumes of water, as energy from falling debris or expansion is transferred to the water into which the debris falls. Tsunamis caused by these mechanisms, unlike the ocean-wide tsunamis caused by some earthquakes, generally dissipate quickly and rarely affect coastlines distant from the source due to the small area of sea affected. These events can give rise to much larger local shock waves (solitons), such as the landslide at the head of Lituya Bay which produced a water wave estimated at 50 – 150 m and reached 524 m up local mountains. However, an extremely large landslide could generate a megatsunami that might have ocean-wide impacts and covers up vast lands, a good example would be the province of Java

The tsunami smashed into a 110-mile stretch of Java’s coastline that was unaffected by the devastating 2004 Indian Ocean tsunami. Waves more than 6 feet high reached 200 yards inland in some places, destroying scores of houses, restaurants and hotels. Cars, motorbikes and boats were left mangled amid fishing nets, furniture and other debris. hope that help you. Cheers

Answer 2

The big tsunami from a couple years ago in Indonesia/Thailand tilted the Earth's axis.

Answer 3

tsunamis could cover some of land and it effects the earth's water percentage
