What are the global impacts of Tonga volcano eruption?

The impact of Tonga volcanic eruption on the world may lead to an abnormal drop in atmospheric temperature, resulting in "volcanic winter". However, it is still necessary to continuously observe the volcanic activity to determine the impact on temperature.

Moreover, some meteorologists pointed out that volcanic eruptions will generally have a lasting impact on the global and East Asian climate in the next 1 to two years, and the cooling effect will be around 0.3℃.

The cause of Tonga volcano eruption:

Mainly due to the movement of the earth's plates. At present, the eruption scale of Tonga volcano is estimated to be 5 or 6, which has affected the Pacific Ocean and triggered tsunamis in Japan, Australia and other places. The abnormal rise of sea waves has also been detected along the coast of China and Zhejiang.

However, it is necessary to continuously observe whether there is a volcanic earthquake. Professor Laban Xiao explained that this volcanic eruption was accompanied by an earthquake and a submarine landslide, and the superposition of these factors would produce a stronger tsunami.
