Question

Discuss the types of tsunamis?

Answer 1

Answer:

Tsunamis are killer waves of local, distant and regional types.

Explanation:

• Tsunamis are tidal waves that move in series and cause displacement of large bodies of water, caused due to the landslides or tectonic shifts or volcanic eruptions, produced within the earth's crust. The gravitational pull of the sun and moon causes huge waves in the ocean waters which form wave high ranges.

• Mostly occurring in the Pacific and Indian oceans, local Tsunamis are those that cause damage in the proximity i.e within 100 kilometers. These can be very dangerous as they take about 10 minutes only to affect the people and hence no chance of predation or warnings.

• Regional Tsunamis are those that cause damage to the 100 to 1000 kilometers from underwater events.  As these provide more waning time than the earlier waves but less than 1 hour as they are within the area of 1000 kilometers.

• Distant Tsunamis are ones that are called Tele tsunamis or ocean-wide tsunamis they often occur with huge destructions and appearing like local Tsunamis but cover a vast expanse of the landmass. The most destructive type of Tsunamis was one on the ocean floor of Indians in 2004 occurring by the earthquake of 9.0 magnitude.
