The tsunami from the volcano circled the Earth twice

(ORDO NEWS) — The shock waves and tsunamis, which have already circumnavigated the Earth twice, reached Eurasia, Australia, North and South America.

Experts are now carefully studying the consequences of the eruption of the underwater volcano Tonga, which completely de-energized the kingdom of the same name with a powerful ash emission, damaged the coastline in dozens of countries and, according to scientists, could become the largest in the world over the past 30 years.

The eruption is viewed from a distance of 65 kilometers. Eyewitnesses admitted that at first they mistook the eruption of an underwater volcano off the coast of the Pacific kingdom of Tonga for a nuclear bomb explosion. Thunder peals were heard on the Fiji Islands 800 kilometers from the epicenter.

A gigantic mushroom rose in the middle of the ocean to a height of 20 kilometers. The ash cloud that was thrown out by the Hunga-Tonga-Hunga-Haapai volcano exceeded 250 kilometers in diameter. The eruption itself occurred on a desert island, which was formed in 2014 as a result of volcanic activity.

Experts have already recognized this eruption as the strongest in the last 30 years. Evidence of this is the tsunami that hit the coast of the main island of the kingdom. Usually, tidal waves do not arise from underwater volcanoes. But in this case, Hunga-Haapai stirred up almost the entire Pacific Ocean.

In Japan, which is located 8 thousand kilometers from the islands of Tonga, the alarm was sounded in the evening, 8 hours after the eruption. Sensors in the ocean, by which seismologists determine the likelihood of a tsunami, showed that the entire east coast of the country is under threat.

Sirens wailed in the port cities. Traffic jams formed in the middle of the night as people chose to spend the night in evacuation centers.

“I heard that the tsunami is about a meter high,” says one of them. “But we don’t really know how high it can rise. I decided it was better to evacuate.”

In Japan, a tidal wave turned the current in the rivers in the opposite direction. The main victims were fishermen whose boats were capsized or sunk. But the very fact that a volcano (and not an earthquake) caused a tsunami on the opposite side of the ocean is an extremely rare phenomenon.

“I think that the eruption led to a change in atmospheric pressure. This can be called an” atmospheric surge “, because of which the tsunami reached Japan,” explains Tohoku University professor Fumihiko Imamura.

The same tidal waves reached Australia, New Zealand, and also the west coast of America – from California to Chile. In the Kingdom of Tonga, which after the tsunami plunged into darkness for several hours due to a dense cloud of ash, the situation is still not clear – communications are not working on the island (the volcano tore the underwater cable).

There are definitely victims – the body of the British Angela Glover, who disappeared after the eruption, was found washed ashore on January 17. In the near future, Australia and New Zealand are preparing to send planes with humanitarian supplies and specialists to the kingdom to assess the extent of the damage. Volcanic ash prevented this before.

According to experts, only in order to restore the Internet and mobile communications on the island, it will take at least a week, of course, provided that there is no re-eruption. But now no one can answer the question – how the volcano will behave further.
