Tonga, an island nation in the southwestern Pacific Ocean, has recently become the focus of global attention.
Volcanic eruption in Tonga
A "once-in-a-millennium" volcanic eruption on The island of Hon Aha Apai, about 65 kilometers north of Tonga's capital Nuku'alofa, triggered a tsunami that swept across the Pacific Ocean in a matter of hours. The tsunami hit Australia, New Zealand, Japan, and the west coasts of North and South America, and atmospheric shock waves were detected around the world.
According to the latest reports, after the end of the volcanic eruption, the land of the erupting island disappeared in large areas.
More experts pointed out that the crater has completely awakened and will continue to erupt for weeks or even years, and it is not clear when the peak of its eruption will come.
The "year without summer" is another issue that experts worry about. In 1815, Mount Tambora in Indonesia erupted violently, cutting the entire summit by more than 1,200 meters and killing more than 50,000 residents. Large amounts of volcanic ash aerosols entered the stratosphere and could not settle, forming a giant umbrella that caused global temperatures to drop by an average of 0.53 degrees in 1816. That year is also known as the "Year without Summer".
This extreme weather not only makes the summer not hot, but also makes the winter extremely cold. Abnormal climatic conditions make crop harvests the most directly affected. Social unrest such as famine and riots caused by the decline in grain production also came.
The number of craters of Mt. Fuji has increased
In addition, according to Korean media reports, the number of Mt. Fuji craters in Japan is also increasing, and has increased nearly 6 times to about 300. Magma is being stored in large quantities inside it. Japanese experts say Mt. Fuji could erupt at any time, and although the last major eruption was 315 years ago, Mt. Fuji has always been an active volcano. Modern technology cannot accurately predict the exact timing of an active volcano eruption and its likely impact.
It has been reported that the eruption of the Tonga volcano indicates that the geological activity of the Earth, especially volcanic activity, is entering a period of high incidence.
China's active volcanoes
The number of active volcanoes in China is much smaller than the number of active volcanoes in Japan.
The three main active volcanoes are Heilongjiang Wudalianchi Volcano, Heilongjiang Jingpohu Volcano, and Jilin Changbaishan Tianchi Volcano. Fortunately, they are basically dormant at the moment.
The Changbai Mountain Tianchi at the crater of Changbai Mountain is the largest crater lake in the mainland. The last eruption of Changbaishan Volcano dates back to 1903.
These volcanic anomalies have not been reported.
