The west coast of the United States issued a tsunami warning, Peru closed 80 ports, and New Zealand

This week, news of the eruption of Tonga's submarine volcano broke the Internet (the submarine volcano erupted, the sea surface violently "exploded"! Many ships capsized or washed away, Tonga lost contact, and the Pacific Rim countries issued an alert!), January On the 14th and 15th, it erupted several times in a row, causing many countries to issue tsunami warnings. At 6:10 on January 17, another "large-scale eruption" occurred. tragic. The tsunami triggered by the submarine volcano has reached the entire Pacific coast.
According to Hong Kong media reports, the shock wave generated by the Tonga volcanic eruption propagated through the atmosphere, and the air pressure in Hong Kong, about 9,000 kilometers away, was also abnormal.

Tsunami warnings issued in many countries/regions

After the eruption of the submarine volcano in Tonga, the tsunami triggered by the tsunami has spread to the entire Pacific Rim coast. In addition to Australia and New Zealand, Fiji, Chile, Canada, the Republic of Vanuatu, the American Samoa Islands, the Australian Autonomous Island Lord Howe Island, Tsunami warnings were issued for Macquarie Island in Australia and the Norfolk Islands, Japan, Hawaii and the west coast of the United States.

The Australian Bureau of Meteorology issued a tsunami warning immediately after the eruption of the Tonga volcano, covering many states and islands along the eastern coast of Australia. The Australian Bureau of Meteorology said on January 16 that the shock wave of the volcanic eruption traveled at a speed of more than 1,000 kilometers per hour, and the atmospheric pressure in Australia changed significantly. The data showed that the wave height reached 1.72 meters near the country's Norfolk Island and 0.82 meters in its Gold Coast area.

The Japan Meteorological Agency issued a tsunami warning for some areas including the Amami Islands on January 16. The tsunami generated the largest wave height off the coast of Japan near the city of Amami, Kagoshima Prefecture, with a wave height of about 1.2 meters; the wave height caused by the tsunami in most other Pacific coastal areas was less than 1 meter. Twenty-two ships capsized, sank or floated in Kochi, five in Tokushima and one in Mie.

A tsunami warning was also issued for parts of the U.S. West Coast, which includes California, Oregon, Washington state and Alaska, now in effect, according to the NWS National Tsunami Warning Center in Palmer, Alaska.

A pier manager at the U.S. port said a 1- to 2-foot tsunami wave initially hit the pier, which coincided with high tide, followed by larger waves.

"In our port, the surge was about 7 feet, and before the swell came in, it sucked everything out of the port and pushed it in quickly. It was about 7 feet of water in 3 minutes, As a result, strong currents are created, which then cause damage to some of the piers."

Beaches and piers throughout Southern California have been closed as a precaution, while urging people to stay away from the water and shore.

The National Emergency Office under Chile's Interior Ministry issued a tsunami warning to most of the Pacific coast and Pacific islands on the 15th, evacuating people from the coast and beaches. The Chilean Navy's Hydrographic and Oceanographic Bureau released news that the country's northern Iquique and other places encountered waves nearly 2 meters high, and Chile is currently not affected. Chilean authorities will continue to monitor changes in ocean tides through 47 monitoring stations along the coast.

80 piers closed due to seawater intrusion in Peru

In Peru, more than 10,000 kilometers from Tonga, the local National Emergency Operations Center said 22 ports were closed as a precautionary measure due to continued "abnormal waves" triggered by the volcanic eruption.

After the second outbreak of the Tonga submarine fire on January 17, the sea water poured back, and the situation became more severe. The country further closed 80 docks.

In addition, the Peruvian National Civil Defense Agency also urged local authorities to guide the public to take appropriate protective measures to prevent personal accidents and property damage, while calling for the suspension of ports and fishing activities and the transfer of small boats to safe areas.
New Zealand delays ship arrivals

The tsunami hit both the west and east coasts of New Zealand's Northland due to the volcanic eruption and the resulting tsunami. The worst damage occurred in Tutukaka, wher 8 to 10 ships were sunk and many others were damaged. also suffered extensive damage.

In addition, the Port of Taranaki recorded unusual waves for 24 hours. In a post on the port's social media page, Ashley McDonald, the head of operations, said there was a lot of activity, "the largest being 1 metre high, and while these waves are invisible to the naked eye, due to every Each wave has a cycle of about 10 minutes, and the water in and out of the estuary and around the harbour breakwaters can be violently gushed in and out.”

"For this reason, the two ships were delayed until the next day before they entered the port."

What is the impact of the tsunami on the international ocean freight business?

The tsunami triggered by the eruption of the submarine volcano in Tonga has already affected the international ocean cargo transportation industry. According to news from freight forwarding companies, beaches and docks throughout Southern California have been closed.

A tsunami warning is now in effect for the U.S. West Coast including California, Oregon, Washington and Alaska. "Due to higher than normal surf, beaches and piers throughout Southern California are closed until further notice as a precaution.

How much impact will the tsunami have on the safe navigation of ship crews?

Industry insiders believe that the tsunami caused by the violent eruption of the submarine volcano in Tonga has little impact on the safety of ships sailing in the ocean, because the tsunami wave is a long wave with a wavelength of hundreds of kilometers, but the wave amplitude is only a few meters. However, the tsunami is extremely harmful to the berthing and anchored ships, and it is very easy to cause the ship to lose its anchor and break the cable, resulting in accidents such as collision and grounding.

As the shock waves caused by the tsunami continue to violently impact the wharf, it is very easy to cause damage to the wharf. Industry insiders remind that once the ship finds the wharf damaged, it should leave the port decisively to ensure the safety of the ship and the crew.
