1900 years ago, Pompeii was instantly frozen under the power of Mount Vesuvius. However, in recent years, the Earth has once again experienced a volcanic rage, and on January 15, 2022, the Tonga volcano erupted, which may reach a magnitude 6 intensity, equivalent to the destructive power of 1,000 Hiroshima atomic bombs. The volcano, located less than 60 kilometers from Tonga's capital, has raised worldwide concerns.
Volcanic strength is usually measured using the volcanic eruption index, which is calculated by the volume of volcanic ejecta, with each stage ten times larger than the previous level, with a maximum of 8 levels. Volcanic eruptions of VEI magnitude 6 are rare in modern history, but the Tonga volcano has been initially assessed to be over magnitude 5 and has the potential to reach magnitude 6. The erupting mushroom cloud is more than 20 kilometers high and 400-500 kilometers in diameter, which is shocking.
With a diameter of 400-500 kilometers, if this volcano erupts in Japan, it will cover most of the bustling areas of the country, causing a huge disaster. In addition, the lightning activity near Tonga makes the sky blood-red and the scene looks like the end times.
Tonga, located in the western South Pacific, consists of 173 islands with a population of about 100,000 and is less than 60 kilometers from the site of the volcanic eruption. The eruption caused communications to be cut off, Tonga was almost completely cut off from the outside world, information was blocked, and the country was isolated.
Tonga is not only exposed to loud impacts, but also the threat of tsunamis of up to 3 metres, which can be widespread and potential disasters are immeasurable.
In addition, volcanic ash threatens air and satellite communications, making it difficult to provide timely assistance. Flights were affected and ships had difficulty accessing areas affected by dust and tsunamis.
The most serious is the toxic gases in volcanic ash, which can pose a serious threat to the people of Tonga and require measures to protect life.
Although Tonga is unlikely to be buried in its entirety like Pompeii, it faces great challenges. The eruption will also have global repercussions, potentially leading to a short-term drop in global temperatures and exacerbating global food shortages.
After these two years of catastrophe, humanity has become vulnerable, and we look forward to the earth being more kind to us. May we face this challenge together and protect the future of life and the planet.
This Tonga volcanic outrage is not just a local natural disaster, it has global implications. As mentioned earlier, this eruption will have a significant impact on global temperatures. The temperature drop of 03-04 degrees, although seemingly small, is enough to trigger major ecological and climate change.
First, falling temperatures on a global scale will have a profound impact on agriculture and food supply chains. Global food production and supply chains, already affected by the pandemic, will suffer further setbacks, leading to food shortages and rising food prices in more regions. This will exacerbate global hunger, especially in regions already facing food insecurity.
Second, falling temperatures could trigger extreme weather events, including more frequent extreme cold and snowfall, putting additional pressure on energy supplies and infrastructure. This can lead to power shortages, heating problems, and traffic disruptions, with wide-ranging negative impacts on social life and the economy.
In addition, sulfur dioxide and other toxic gases released by volcanic eruptions will pollute the atmosphere, potentially triggering a drop in air quality and affecting human health. This contamination is not limited to areas near volcanoes, but can also spread further afield, potentially harming a wide range of people.
Finally, the eruption will also shed light on scientific research and monitoring. We need stronger global monitoring systems to provide earlier warning of volcanic eruptions and other natural disasters to reduce losses and protect the vulnerability of human societies.
Overall, the Tonga volcanic eruption is a reminder of the powerful and unpredictable nature of the earth's natural forces. It calls for greater solidarity and collaboration on the part of the international community to respond to possible future natural disasters and protect our fragile planet and life. Only through global cooperation can we better withstand these challenges and create a safer and more sustainable future.
