What is the impact of Tonga volcano eruption on neighboring countries?

In Tonga, a South Pacific island country, 14 and 15 had violent volcanic eruptions for two consecutive days. The Australian Meteorological Administration said on June 5438+05 that a tsunami wave with a height of1.2m was observed in Nuku 'alofa, the capital of Tonga.

Japan, the United States, Canada, New Zealand, Fiji, Samoa, Vanuatu, Australia and Chile all issued tsunami warnings. Some experts said that the crater has awakened and the active eruption period can last for weeks or even years. Such a large-scale volcanic eruption shocked the international community, and some public opinion even worried that "Tonga will sink."

The submarine volcano eruption in Tonga, a South Pacific island country, started in June, 5438+04, affecting many countries. On June 16, there were 19 fishing boats capsized or sank in Duokou Port, Kochi Prefecture, Japan.

Influence of Tonga volcano eruption on climate

According to the analysis of meteorological enthusiasts in China, the eruption of Tonga volcano is not enough to transport the huge amount of volcanic ash that affects the global climate to the stratosphere; The location of volcanic eruption is in the southern hemisphere, and its influence on the northern hemisphere is relatively small.

Therefore, the impact of Tonga volcano eruption on the global climate, especially on the northern hemisphere, should be weaker than that of Pinatubo volcano and smaller than that of Tambora volcano, so it is unlikely that there will be a "year without summer" in the northern hemisphere.

From June 5438+1October 65438+July, 2022, it was learned from China Meteorological Bureau that the monitoring of Fengyun -3 D star in China showed that the eruption site of Tonga volcano was located in the south of the key monitoring sea area of El Ni? o-La Ni? a phenomenon. Volcanic eruption will affect the current development trend of La Nina state through air-sea interaction.

Before the eruption, there was strong convection activity over Indonesia, and now volcanic ash has begun to spread westward. It is necessary to be alert to the impact of extreme weather such as convection development and secondary rainstorm on the affected areas.
