“Tonga eruption has one big explosion every 1000 years”… The Korean Peninsula is safe as there is no undersea volcanic activity

As a large-scale submarine volcano erupted from Tonga, an island nation in the South Pacific, questions about the possibility of a submarine volcano eruption on the Korean Peninsula are growing.

18 days <뉴스1> According to the report, at about 1:10 pm (Korea time) on the 15th, a volcano erupted near Hunga Hapai Island, Hunga Tonga, 65 km north of Nuku’alofa, the capital of Tonga.

Volcanologist Robin George Andrews told Middle Eastern media Al Jazeera that it was a “big bang that would happen once in a thousand years.” In the aftermath of the eruption, a 1.2m high tsunami struck Nuku’alopa, and a tsunami warning was issued at one time in Japan, the United States, and New Zealand about 10,000 km away.

Fortunately, it is not expected to have a direct impact on Korea. In Korea, the Japanese archipelago is obstructed diagonally, so the possibility of a tsunami is low.

Strong winds of 30-65 km/h are blowing from the far seas in the central part of the East Coast and the far northern seas in the southern part of the East Sea, where a storm warning is currently in effect, and the waves are very high at 1.5-4.0 meters. did.

If so, is there a possibility that a submarine volcano around the Korean Peninsula will explode? In conclusion, the possibility is very slim.

Ulleungdo, Dokdo, and Jejudo, which are submarine volcanoes, are classified as active volcanoes, but they are known as volcanic bodies with little large-scale volcanic activity during the Holocene (within 10,000 years). The last eruption was also 5000 and 1000 years ago, respectively. There are no clear signs of activity.

In comparison, Tonga Volcano erupted on a large scale in 2009 and 2014, and since the eruption began last month, the danger has been constantly warned.

An official from the Korea Meteorological Administration explained, “It can be said that there is no submarine volcano around the Korean Peninsula that rises above the surface or sinks again, causing earthquakes and tsunamis, like the Tonga Volcano.”

Experts also believed that the possibility of an underwater volcano erupting around the Korean Peninsula was low.

Hong Tae-kyung, a professor of earth systems at Yonsei University, said, “There are traces of activity hundreds of thousands of years ago in the waters off Ulleungdo, but there are no active volcanoes around the Korean Peninsula other than Jeju Island and Mt. Baekdu.”

Professor Hong said, “When a submarine volcano on the eastern coast of Japan erupts, depending on the explosive force, if the ground shakes violently like an earthquake, it can cause pressure changes in adjacent volcanoes and cause volcanic activity. However, the possibility of reaching Korea is very low,” he explained.

On the other hand, it is estimated that there are about 30,000 submarine volcanoes worldwide. There are at least 30 submarine volcanoes in Japan, which is adjacent to Korea. In addition, Krakatau, Indonesia, veterans of the South China Sea, Loihi, Hawaii, and Santorini, Greece are widely known as submarine volcanoes.
