The submarine volcano of Hong Aha Apai Island in the South Pacific island nation of Tonga erupted violently on January 14 and 15. Multinational experts believe that this may be the world's largest submarine volcanic eruption in 30 years.

From the satellite cloud map, the topography of the island has changed dramatically before and after the volcanic eruption.

According to the analysis of a number of experts in Australia and New Zealand, the tsunami caused by the submarine volcanic eruption is huge, and the volcanic ash will have different degrees of impact on the surrounding atmosphere, ocean currents, fresh water, agriculture and people's health, and the specific situation needs to be further evaluated.
