An unusual phenomenon about the tsunami in Japan!!!
• Mariners who escaped the onslaught of the tsunami soon had to contend with another peril - the appearance of vast whirlpools off the coast of Japan.刚刚逃 过滚滚而来的巨大海啸浪涛的船员还来不及喘息，就又将面对另一处险象环生的挑 战——在日本近海岸线上出现的巨大漩涡。 The powerful vortices appeared yesterday morning when the oceans, swollen by the vast surge of water, began to recede. The powerful vortices appeared yesterday morning when the oceans, swollen by the vast surge of water, began to recede.在广大淹水地区出现“退水”的情况下，出现威力强劲的大漩涡。 As the water levels fell, whirlpools hundreds of yards wide appeared, sucking everything into the themselves and creating new danger for passing boats.随着水位的下降，漩涡的范围扩张到几十码的区域，它毫不留情滴将周围的所 有一切都吸入其内，这又给过往的船只造成了新的危险。 Whirlpools are created by rising and falling water - and are a common feature of tsunamis. But they are rarely as spectacular - or as well photographed.漩涡是由于水涨水退的变化而引起的，是海啸所常常伴随的现象，但 拍摄到如此大规模的海啸，的确实属少见 Dr Simon Boxhall, of the National Oceanography Centre in Southampton, said: 'It's exactly the same thing that happens when you take a plug out of a bath or sink.来自南安普敦国家海洋学中心的西蒙·博克斯霍尔教授说，“这样情况就 如同与你将蓄满时的鱼缸或水槽的塞子拔掉一样。”

Tsunamis are destructive waves caused by earthquakes, volcanic eruptions, underwater landslides, or climate change. The speed of tsunamis can be as high as 100m/s to 200m/s in the ocean. And it can cross the ocean within hours. The wavelength can reach hundreds of kilometers and the tsunami can spread thousands of kilometers with little energy loss. The waves are less than a meter high in the ocean, but when they reach the coast, their wavelength is shortened and the wave height increases dramatically, reaching tens of meters, forming a "water wall" with enormous energy.

Do not raise your hand in the water, do not struggle. You should reduce the movement as far as possible. float in the water with the wave is what you are expected to do . You will not only avoid sinking, but also reduce the unnecessary energy consumption by doing this.
If you are unlucky enough to fall into the water in a tsunami, please try to grab some branches, boards and other things that can be suspended in the water.

The global tsunami zone is roughly the same as the earthquake zone. Tsunami is mainly controlled by submarine topography and coastline geometry and wave characteristics. The walls of the wave ice have been repeated every few minutes or tens of minutes, destroying the Banks, flooding the land, destroying the property, which is extremely destructive.

Step 2: Keep a radio on hand at all times and take official warnings seriously. People who live in areas prone to Tsunamis must always follow official warnings and directions right away.

Lecture 6 Tsunami
Southeast Asia Tsunami 2004
The sea bed is estimated to have risen by several meters, displacing an estimated 30 cubic kilometers (7 cubic miles) of ocean water and triggering devastating tsunami waves
The massively bigger India and Australian plates easily “shove” the smaller Burma microplate（缅甸微板 块） around
Southeast Asia Tsunami 2004
Seismographic data revealed that the first phase involved a rupture about 400 kilometers (250 miles) long and 100 kilometers (60 miles) wide, located 30 kilometers (19 miles) beneath the sea bed, which is the longest rupture ever known to have been caused by an earthquake
Southeast Asia Tsunami 2004
Then a pause of about 100 seconds took place before the rupture continued northwards towards the Andaman and Nicobar Islands There was a vertical change along the rupture that ranged from a few meters up to 50 meters
关于海啸( tsunami)的PPT
Translation:
What does the Japanese word “tsunami” mean? Tsunami is a Japanese word with the English translation, “harbor wave.” Represented by two characters, the top character, “tsu,” means harbor, while the bottom character, “nami,” means “wave.”
Tsunami vs. Wind Wave:
Tsunamis are often no higher than wind-driven beach waves but they are much more dangerous.
Historic tsunamis
• Highest or tallest The tallest tsunami ever recorded so far is the 1958 Lituya Bay megatsunami(立图亚湾巨型海啸）, which had a record height of 524 m (1742 troyed town after being hit by a tsunami, caused by the 2004 Indian Ocean earthquake
The Development of a Tsunami:
• A tsunami starts when a huge volume of water is quickly shifted. This rapid movement can happen as the result of an underwater earthquake (when the sea floor quickly moves up or down), a rock slide, a volcanic eruption, or another highenergy event. • Not all earthquakes generate tsunamis. To generate tsunamis, earthquakes must occur underneath or near the ocean, be large and create movements in the sea floor. All oceanic regions of the world can experience tsunamis, but in the Pacific Ocean there is a much more frequent occurrence of large, destructive tsunamis because of the many large earthquakes along the margins of the Pacific Ocean.
