A European earth observation satellite captured imagery of what appears to be waves spreading after an underwater volcano erupted off the island nation of Tonga on January 15.
The satellite passed near Tonga and collected data about 13 hours after the eruption. The satellite's radar allows detailed observation of Earth's surface and changes in sea surface.
Tofua Island, which is about 100 kilometers north of the volcano, is near the center of the imagery taken from the satellite. Semicircular waves can be seen spreading over dozens of kilometers around the island.
Professor Mori Nobuhito at the Disaster Prevention Research Institute of Kyoto University is an expert on tsunamis and high waves. He said the imagery captured the sea-surface change after the eruption.
Mori pointed out that each wave was up to five kilometers apart from the next one, which is a much narrower interval compared with tsunamis generated by earthquakes.
He said this led to a shorter period between each wave, which corresponds with what was indicated by the data collected by tide gauges at various locations after the eruption.
Mori said this observation is very rare, and the data is important to help understand how the sea surface changed after the eruption.
He added that if the intervals are shorter, waves tend to move in a complicated way, as they are reflected over terrain.
Mori said waves with shorter intervals were apparently traveling back and forth in the Pacific even half a day after the eruption, which possibly led to the waves of various heights that were observed around Japan.
He also said the sea-surface change was a very rare and complicated phenomenon caused by multiple factors, including a change in atmospheric pressure after the eruption.
He said that he believes the spatial data will lead to a deeper understanding of the entire phenomenon.
Key words : 90 percent

The US Centers for Disease Control and Prevention says new research shows a booster dose of a coronavirus vaccine is 90 percent effective in preventing hospitalization due to infection with the Omicron variant.
The CDC on Friday released its study on the effectiveness of booster shots of the Pfizer and Moderna vaccines, based on data from medical institutions across the country.
It says that two doses of the vaccine were 81 percent effective against hospitalization after six months when the Delta variant was surging, and 57 percent when the Omicron variant became dominant.
However, a booster shot raised the effectiveness to 94 percent during the Delta wave, and to 90 percent during the Omicron surge.
Unvaccinated people aged between 50 and 64 are 44 times more likely to be hospitalized for COVID-19, compared to fully vaccinated and boosted individuals. The figure rose to 49 times among those aged 65 or older.
CDC Director Rochelle Walensky said the research demonstrates that protection against hospitalization is higher for those who have had booster shots. She urged people who are eligible to get their booster shot to get it as soon as possible.

The daily tally of new cases of coronavirus infection in the United States remains high at more than 700,000, creating staff shortages at schools and hospitals.
The daily national count of confirmed new infections has surpassed 1 million on some recent days.
The figure has been continuing to surge in southern, midwestern and western states in contrast to a downtrend observed since mid-January in the eastern state of New York and elsewhere.
The Centers for Disease Control and Prevention says as of Wednesday, the seven-day average of new cases in the US stood at more than 740,000 while that of new hospital admissions hovered above 20,000.
National Guard personnel have been helping with non-medical jobs at hospitals across the western state of Oregon to lessen the burden on medical professionals.
Parents of students have been teaching classes at some schools in the southern state of Texas due to the spread of infections among educational staff.
The CDC predicts that the coronavirus will continue to spread across the US, raising the possibility that about 61,000 more people could die from the virus over the next four weeks.

Sunday marks two years since China imposed a lockdown on the city of Wuhan to bring the coronavirus outbreak under control.
The lockdown on Wuhan in Hubei Province came amid the world's first confirmed outbreak of COVID-19 in the city. The measure lasted for two-and-a-half months.
Wuhan's health care system collapsed due to a surge in the number of coronavirus patients.
Authorities say that as of April 2020, more than 3,800 people had died of the disease in the city. But they say no community transmission of the virus has been observed in the city since last August.
The central government has been maintaining a "zero-COVID" policy to prevent the spread of the virus. It involves large-scale PCR testing and lockdowns on areas where infections have been reported.
Authorities implemented a de facto lockdown on the city of Xi'an in Shaanxi Province last December. The city has a population of about 13 million, making the measure equivalent to Wuhan's in the number of people affected. The lockdown remains in effect in part of Xi'an.
Authorities also sealed off some areas of Beijing, the nearby city of Tianjin, and elsewhere after cases of the Omicron coronavirus variant were detected there.
Officials are now scrambling to contain infections ahead of the Beijing Winter Olympics, whose opening ceremony takes place on February 4.

The Chinese government has tightened its control on information about the coronavirus in the country. Authorities detained people who tried to tell the world about the city of Wuhan when it was put under lockdown two years ago.
Independent journalist Zhang Zhan traveled to Wuhan during the lockdown and shared online firsthand accounts, including ones about citizens who were forced to live a tough life. The Shanghai native was detained by authorities for spreading false information.
In December 2020, a court sentenced Zhang to four years in prison for disrupting public order. She is still serving time in prison.
Her lawyers argue the ruling was unfair.
In November, the US Department of State and international human rights groups urged the Chinese government to free her immediately.
One of her lawyers, Zhang Keke, says he hopes Zhang will be released as soon as possible. He also wants many people to pay attention to this issue.
Some people point out that the initial response to the outbreak in Wuhan by President Xi Jinping's leadership was delayed. The government is apparently trying to control information to stem critical opinions.

The head of the International Campaign to Abolish Nuclear Weapons, or ICAN, has urged Japan to contribute to the treaty's effort against nuclear weapons.
Saturday marked one year since the UN treaty banning the use, development and possession of nuclear weapons took effect.
Fifty-nine countries and regions have ratified the treaty. But Japan, which is under the US nuclear umbrella for its security, is not a signatory, along with nuclear states such as the United States and Russia.
Executive Director of ICAN, which won the 2017 Nobel Peace Prize for its contribution to the adoption of the treaty, Beatrice Fihn spoke with NHK.
Fihn expressed her strong concern over the present situation where nuclear states are modernizing their arsenals.
She warned of the dangerous situation stemming from the tensions between the US, and China and Russia while expressing appreciation for the participation of more countries.
The Executive Director said the "risk of nuclear weapons use is increasing" and it is urgent to "work on nuclear disarmament" and work with the treaty on nuclear prohibition.
She said that non signatory countries including Germany and Norway have shown their intent to take part as observers in the first meeting of signatories which is scheduled in March this year.
Fihn explained that a very concrete discussion about victim assistance, a subject in which the Japanese government has a lot of expertise, is to take place at the meeting and stressed that Japan could contribute much in a non-political way.

Pottery makers in the western Japanese city of Koka in Shiga Prefecture are busy making dolls for the Girls' Festival on March 3.
The region is known for its pottery called "Shigaraki-yaki," and statues of raccoon dogs.
One of the potters, Kuzuhara Junko, has been making what are known as Hina dolls.
She kneads a lump of clay and cuts out parts for kimono. Pine branch and chrysanthemum patterns are then embossed into the kimono.
Small clay spheres are transformed into faces by carving eyes, nose and mouth with a needle.
After the clay dolls are dried for about ten days, they are painted and baked in a kiln several times.
Kuzuhara says that she makes the dolls, hoping that they will help people think of the coming spring and be uplifted, as many are feeling down amid the coronavirus pandemic.
The doll making will continue till mid-February.
