There has never been a 300 meter high tsunami in history

There was no tsunami 300 meters high In the 16th century B.C., the volcano of Santorin Island north of Crete underwent an extremely violent volcanic eruption, after which only the island of Thera and some small islands stood in the Aegean Sea. Tsunami experts later found that the tsunami caused by the eruption rose more than 90 meters above sea level and reached the Nile Valley, 300 kilometers away.

1958: The tallest wave ever recorded—the crest of the wave was nearly 500 feet taller than the Empire State Building—crashed down the Gulf of Alaska toward Lituya Bay. (Note: Empire State Building 381 meters, 500 feet = meters).

1958 year. The Tsunami in the Gulf of Litua in Alaska, USA, can be called the world's "devil's tsunami", it once set off a huge wave of 524 meters, with a speed of up to 150 kilometers per hour, which is no less powerful than a nuclear bomb in the water, which shows how terrible the power of the tsunami is.

The area in the ** zone is also a frequent tsunami zone.

Scientific studies have shown that the global tsunami outbreak area is almost the same as the **zone, so the United States is also in the occurrence of 8 3 magnitude **, only after the unprecedented tsunami crisis, the current global record of destructive tsunamis is about 260 times, so calculated, an average of six to seven years will occur, of which the Pacific Rim of the tsunami accounts for about 80, and the Japanese sea accounted for about 60 of the Pacific Rim tsunami, that is, Japan is the world's ** The countries that suffered the most from the tsunami.

The Litua Bay tsunami struck on 9 July 1958, when a massive earthquake triggered a landslide that plunged more than 30 million cubic metres of icebergs into Alaska's Litua Bay. As a result, the waters of the Gulf of Litua have been severely displacedA tsunami of up to 524 meters was caused. The tsunami was the highest tsunami on record, which also upended the oceanographer's perception of the tsunami.

Tsunamis can reach up to 85 meters in height, and the world's highest tsunami is the Ryukyu Islands tsunami in 1771, which is a destructive wave caused by the seabed**, volcanic eruptions, submarine landslides or meteorological changes, and the speed of the tsunami is as high as 700-800 kilometers per hour. When a tsunami occurs, the ** wave travels far away in an ever-expanding circle on the surface of the sea. At a high speed of 600-1,000 kilometers per hour, it gallops 10,000-20,000 kilometers on the unobstructed ocean, setting off 10-40 meters high waves crashing on the shore.

The physical basis of tsunami warning is that the propagation speed of the wave is faster than that of a tsunami.

During the dinosaur period, the super tsunami caused by the asteroid hitting the Earth. It should be considered the highest.

Tsunamis can reach up to 85 meters, and the world's tallest tsunami was the Ryukyu Islands in 1771.

Tsunami, tsunami is caused by the bottom of the sea**, volcanic eruptions.

Destructive waves from submarine landslides or climate change, with tsunami waves reaching speeds of up to 700-800 kilometers per hour.

Tsunamis are usually caused by seafloors with an epicenter within 50 km below the seafloor and above the earthquake level**, but can also be caused by underwater, coastal landslides or volcanic eruptions. After a single jolt, the ** wave travels a great distance in an ever-expanding circle on the surface of the sea. The wavelength of a tsunami is larger than the maximum depth of the ocean, and the waves can travel regardless of the depth of the ocean.

In August 1883, the volcanic eruption on the Indonesian volcanic island of Krakatoa was the worst in human history. The eruption can be heard as far away as Australia. The tsunami waves caused by volcanic eruptions were as high as 130 feet (40 meters).

Tsunamis are natural phenomena caused by underwater **, volcanic eruptions, underwater subsidence and landslides, and are accompanied by loud noises. It is a wave with great destructive power, the most powerful force of nature on the planet.

Tsunamis travel at a speed of about 500 to 1,000 kilometers per hour in the ocean, and the distance between two adjacent waves can be as far as 500 to 650 kilometers

There has been no tsunami in China in recent decades.

Chinese scholars found that in 47 BC (that is, the first year of Yuanren in the Western Han Dynasty) and 173 AD (the second year of Xiping in the Eastern Han Dynasty), China recorded the tsunami of Laizhou Bay and Huangxian County, Shandong. These records have been widely cited by foreign scholars, and are considered to be the world's earliest two tsunami records, and the global tsunami occurrence area is roughly consistent with the ** zone. There are about 260 destructive tsunamis recorded worldwide, an average of about 260.

It happens once every six or seven years. The Tsunami in the Pacific Rim accounted for about 80% of the total number of tsunamis. The Japanese archipelago and its nearby waters account for about 60% of the tsunami in the Pacific Ocean, and Japan is the country that has suffered the most from the tsunami in the world.

The world's highest tsunami was the Ryukyu Islands tsunami in 1771, with waves 85 meters high.
