Recently, a tsunami was observed in the capital Nuku'alofa following a violent eruption of the underwater volcano on Hongaha'apai Island in the South Pacific island country of Tonga. Global experts have been graded: this time it is VEI6, the equivalent of VEI6 energy burst is 620 million tons of TNT explosives, and the number of nuclear bombs is 48,000.
According to the latest news from Agence France-Presse on the 17th, a monitoring station in Darwin said that another "big eruption" occurred in Tonga's submarine volcano.

Tonga's nationwide communications outage
The volcanic eruption ejected impurities such as volcanic ash into the sky. It is estimated that the ash column at the time of the eruption was about 5 kilometers in diameter and 20 kilometers high. The tsunami and volcanic ash caused by the eruption severely disrupted local communication networks.
A 1.2-meter-high tsunami occurred in the capital Nuku'alofa, and a large number of residents near the coast flocked to the highlands for shelter. Tonga's King Tupou VI also reportedly evacuated the palace and was escorted by police to a villa far from the shore.
Communications across Tonga were cut off for a while. Some Tongan residents rushed to upload blurry photos and videos on social media before undersea cables were destroyed. Up to now, most of the communication in Tonga (the full name of the Kingdom of Tonga) is still blocked and lost to the world.
New Zealand Prime Minister Ardern said that the New Zealand authorities are trying to get in touch with Tonga, but due to the seriousness of the disaster, it is difficult to carry out assessment work, and it is not yet possible to count local casualties and property damage. Experts say the eruption could last for weeks or months.
Tongan activist Pakilau Manase Lua, who lives in New Zealand, said the tsunami was just one of the disasters that followed the eruption, with volcanic ash, breathing difficulties and acid rain damaging water sources.
Shane Cronin, a volcanologist at the University of Auckland in New Zealand, said it was Tonga's biggest volcanic eruption in 30 years.
Fortunately, @ Consul Express posted on Weibo that after preliminary verification by the Chinese Embassy in Tonga, there is no report of casualties of Chinese citizens.

Tsunami warning for many countries along the Pacific coast
Tonga's volcanic eruption is so powerful that it will surely spread to other countries.
According to the latest monitoring results, the Tsunami Warning Center of the Ministry of Natural Resources analyzed that the volcanic eruption triggered a transoceanic tsunami that affected the entire Pacific coast. Countries such as Chile, Japan and New Zealand on the Pacific coast have observed significant tsunami waves, with the maximum tsunami wave amplitude reaching 1.5 meters.
Among them, a tsunami danger occurred along the coast of Japan, 8020 kilometers away from Tonga, causing damage to ships along the coast. More than 30 ships have been confirmed to have sunk or capsized in places such as ports in Kochi and Tokushima prefectures on the Japanese island of Shikoku.
Affected by the eruption of the Tonga volcano, the government of New South Wales, Australia, closed all beaches in the state.
Tsunami waves were detected in the coastal waters of China in the early morning of the 16th. Among them, the largest tsunami wave at the Shipu Station in Zhejiang was about 20 cm, and the tsunami waves at the other tide level stations were all less than 15 cm. This process did not cause catastrophic impact on my country's coast.
Most of the Pacific Rim, including Fiji, has issued a tsunami warning. Because the signal from Tonga cannot be contacted now, the signal from Fiji is used in the live broadcast. It is worth mentioning that Fiji, which is 800 kilometers away from the volcano of Chinese said that when the volcano erupted, the local feeling was very obvious.
New Zealand's Civil Defence Emergency Management, more than 2,000km away from Tonga, also issued a warning to residents on the northeast coast of unusually strong waves crashing ashore. One local climate enthusiast tweeted: "The force was so strong that people all over New Zealand heard the 'sonic blast'."
The U.S. Tsunami Warning Center issued a tsunami warning to Hawaii, the northwest coast of the United States, Alaska and other places. A low-lying parking lot in Santa Cruz, California, has been flooded, and regulators have temporarily closed beaches and commercial facilities along the coast.

Trade between Tonga and China
Foreign Ministry Spokesperson Wang Wenbin made remarks on Tonga's volcanic eruption. The Chinese side is very concerned about the Tonga volcanic eruption, which caused tsunamis, volcanic ash and other disasters. The Chinese embassy in Tonga launched the emergency plan immediately and learned about the disaster situation of Chinese citizens. So far, no reports of casualties of Chinese citizens have been received.
He also said that China and Tonga are comprehensive strategic partners. China expresses its deep sympathy and sincere condolences to the Tongan government and people, and is willing to provide support and assistance within its capacity at the request of Tonga.
Tonga has basically no mineral resources on land, so its economy is mainly based on agriculture, fishery and tourism. Tonga is rich in fishery resources and mainly exports tuna.
