Sea-related tourism in Sanya has been suspended due to the typhoon. Is it possible that the typhoon could trigger a tsunami?

Sanya’s sea-related tourism has been suspended due to the typhoon. Is it possible that the typhoon could trigger a tsunami? Guys, this is a great question. The good thing is that it is relatively objective and fair in stating the facts without any bias. Moreover, the issues it touches on are topics related to people's relations and are relatively down-to-earth. In addition, the second half of this question is of a popular science nature. The editor has always insisted that writers should be impartial when describing facts. This is our conscience and responsibility. In addition, words have a power that cannot be ignored. Therefore, popularizing science, disseminating knowledge, and resolving misunderstandings are also the responsibilities of literary workers. Okay, based on the above principles, the editor will elaborate on this issue.

According to the Hainan Provincial Meteorological Observatory’s forecast, the tropical depression in the central South China Sea intensified into this year’s No. 8 typhoon (tropical storm level) at 17:00 on the 22nd. At 8:00 on the 23rd, the center was located about 210 meters east-southeast of Sanya. Kilometers of sea surface, it will make landfall along the coast from Lingshui to Sanya, Hainan Island, from the night of the 24th to the morning of the 25th, or pass by the southern coast of Hainan Island. Affected by this, there will be an obvious storm in Hainan from the 23rd to the 25th. The Hainan Provincial Meteorological Bureau continued to issue a level three typhoon warning at 6:00 on the 23rd. Affected by the typhoon, Sanya closed beaches and suspended sea-related tourism. So the question is, is it possible for a typhoon to trigger a tsunami?

As far as the editor knows, tsunamis may be caused by geological activities such as underwater earthquakes, volcanic eruptions, or underwater collapses and landslides. When an earthquake occurs on the seafloor, the power of the shock waves causes the seawater to undulate violently, forming powerful waves that continue to push forward and submerge coastal areas one by one. Such a disaster is called a tsunami. Typhoons do not belong to geological activities such as underwater earthquakes, volcanic eruptions, or underwater collapses and landslides. It is only a meteorological disaster, so it will not cause a tsunami, but only a storm surge.

So what is a storm surge? According to experts, storm surge is a disastrous natural phenomenon. Severe atmospheric disturbances, such as strong winds and sudden changes in air pressure (usually referring to disastrous weather systems such as typhoons and extratropical cyclones), cause abnormal rise and fall of sea water, causing the tide level of the affected sea area to greatly exceed the normal tide level. It's called a storm surge. It can also be called "storm water increase", "storm tsunami", "meteorological tsunami" or "wind tide". According to the nature of the storm, storm surges can usually be divided into two categories: typhoon storm surges caused by typhoons and extratropical storm surges caused by extratropical cyclones.

Typhoon storm surges are more common in summer and autumn. Its characteristics are: fierce, fast, strong and destructive. Typhoon storm surges occur in all maritime countries and coastal areas affected by typhoons. Extratropical storm surges mostly occur in spring and autumn, and sometimes occur in summer. Its characteristics are: the water increase process is relatively gentle, and the water increase height is lower than the typhoon storm surge. It mainly occurs in mid-latitude coastal areas, mostly along the North Sea coast of Europe, the East Coast of the United States, and the northern coast of my country. To sum up, it is true that Sanya has suspended sea-related tourism due to the typhoon, and it is also very necessary.

As for whether the typhoon may trigger a tsunami? My answer is, no!
