The tsunami triggered by the magnitude 9.0 earthquake off the coast of Japan on March 11, 2011 reportedly struck a coastal city in Japan at just over 23 meters (77 feet) high. In many places along Japan's coasts the waves were up to 4 stories high at 10 meters (33 feet). The tsunami wave speed was estimated to be 500mph or 800 kilometers per hour, which crossed the Pacific Ocean reaching the Coastlines from Alaska to Chile.
In comparison, the 2010 Chile earthquake generated tsunami waves measuring 2-9 meters along the northeastern Honshu coastline in Japan.
The 2011 Christchurch earthquake produced a series of 3.5 m (11 ft) high tsunami waves.
The highest tsunami apparently is the 1958 Lituya Baymega-tsunami with a record height of 524 m (1742 ft), which is taller than the Empire State Building and Sears Tower for comparison.

Why did you not have tsunami 20 years ago?
There have been tsunamis through all of Earth's history. They did not just start in the past 20 years.
When was the last time a tsunami happened?
One occurred in Japan just last week, on March 11, 2011. It was triggered by a 9.0-magnitude earthquake that shook beneath the Pacific Ocean close to Japan. The tsunami ran 500 mph until it hit land, and the impact was so hard that California received tsunami warnings too. A tsunami hit Hawaii, and another hit Southern Cali. It didn't cause much damage to California, except for Crescent City and San Pedro.
How many tsunamis are recorded over past 50 years?
In the past 100 years we have had nearly over 200 tsunamis have been recorded (only ones that caused some damage). Japan has suffered a majority of them.
Why do tsunamis bypass Australia?
They don't. According to recent research by the University of New South Wales in Sydney, in the past 130 years, the Australian continent has experienced 145 tsunamis, resulting in 11 deaths. See the related link below for an article on this research. The difference is that Australia has been relatively free of significant damaging tsunamis, and this is why many people believe that tsunamis are not a threat to Australia. The largest tsunami to hit Australia occurred on the northwestern coast at Cape Leveque in August 1977. This tsunami was 6m in height, but no one was killed. However, recent research has indicated that, in the past 130 years, the continent has experienced 145 tsunamis, resulting in 11 deaths. 85 percent of these have been along the eastern coast.
Why did the Japan tsunami 2011 occur?
The earthquake that hit Japan was a magnitude of 8.8 which means the shaking triggered the waves of the ocean and made them grow larger and larger until it hit land. The tsunami was past 15 feet and killed many people.
How has japan tried to prepare for tsunamis in the past?
Japan knows they have tsunamis when a valcano erupts or a earthquake happens.
Where and how often are tnunamis generrated?
Tsunamis are generated when fault lines under the ocean slip past each other during an major undersea earthquake. Japan's recent earthquake caused a tsunami that somewhat threatened the West Coast of the USA. and Japan itself. Roughly 6 tsunamis are generated every century.

Where have some tsunamis happen in the past year?
a tsunami happened in Hawaii in the summer and that's all i know
How did the tsunami erupt in japan?
Tsumanis do not erupt; volcanoes erupt. Tsunamis are waves caused by friction between two plates underneath the ocean. When two plates try to move past each other, most of the time there is no issue. Sometimes, though, the plates will get stuck until there is finally enough pressure to push past the obstruction. This built-up pressure is released into the surrounding ocean and leads to tsunamis. Japan sits at the border between four different plates and as a result, experiences many tsunamis.

Could tsunamis affect the US or have tsunamis in the past?
Yes. Tsunamis have struck Hawaii, Alaska, California, Oregon, and Washington with varying degrees of damage. There is also some concern for the east coast. It is not a question of if a tsunami will affect the U.S. in the future, it's a question of when.
Has a tsunami originated in pacific ocean this past 100 years?
Yes. There have been several. The most notable one struck on March 11, 2011m killing more than 15,000 people in Japan. Other Pacific tsunamis of note struck in 1946 and 1960.

In the past 100 years we have had nearly over 200 tsunamis have been recorded (only ones that caused some damage). Japan has suffered a majority of them.
Are Tsunamis very common in Australia?
Tsunamis are more common than realised in Australia, possibly because the continent has been relatively free of major damaging tsunamis. However, recent research has indicated that, in the past 130 years, the continent has experienced 145 tsunamis, resulting in 11 deaths. 85 percent of these have been along the eastern coast.
