Indonesia Tsunami Sensors Failed To Detect Huge Waves: Official

Jakarta, Sept 30: Indonesia's geophysics agency lifted a tsunami warning 34 minutes after it was first issued following a major earthquake that sent huge waves crashing into the northeastern coast of Sulawesi island, killing hundreds and leaving thousands more homeless.

The 7.5 magnitude quake and tsunami, which hit the city of Palu about 1,500 km (940 miles) from Jakarta and further along the coastline, killed at least 384 people. Officials said on Saturday the death toll was likely to rise.

Hundreds of people had gathered for a festival on the beach in Palu on Friday when waves as high as six metres (18 feet) smashed onshore at dusk, sweeping many to their death.

The geophysics agency (BMKG) faced criticism on Saturday on social media, with many questioning if the tsunami warning was lifted too soon.

The agency said it followed standard operating procedure and made the call to "end" the warning based on data available from the closest tidal sensor, around 200 km (125 miles) from Palu.

"We have no observation data at Palu. So we had to use the data we had and make a call based on that," said Rahmat Triyono, head of the earthquakes and tsunami centre at BMKG.

He said the closest tide gauge, which measures changes in sea level, only recorded an "insignificant", six-centimetre (2.5 inches) wave and did not account for the giant waves near Palu.

"If we had a tide gauge or proper data in Palu, of course it would have been better. This is something we must evaluate for the future," said Triyono.

It was not clear whether the tsunami, which officials say hammered Palu and the surrounding area at extremely high speeds measuring in the hundreds of kilometres per hour, occurred before or after the warning had been lifted.

"Based on the videos circulating on social media, we estimate the tsunami happened before the warning officially ended," Triyono said.

Indonesia sits on the Pacific Ring of Fire and is regularly hit by earthquakes. The most devastating came on Boxing Day in 2004, when a magnitude 9.5 quake triggered a massive tsunami that killed around 226,000 people along the shorelines of the Indian Ocean, including over 126,000 in Indonesia.

The scenic town of Palu sits at the mouth of a narrow bay in northeastern Sulawesi and is home to around 380,000 people. It was hit by a tsunami in 1927 and 1968, according to Indonesia's national disaster mitigation agency (BNPB).

Baptiste Gombert, a geophysics researcher at University of Oxford, said it was "surprising" the quake had generated a tsunami.

Friday's quake was recorded as a "strike-slip" event where neighbouring tectonic plates move horizontally against each other, rather than vertically, which is what usually generates a tsunami.

"There is some speculation that there was a landslide under the sea which displaced a lot of water and caused the tsunami," he said, adding the narrow bay may have concentrated the force of the waves as they moved toward the shore.

Sutopo Purwo Nugroho, spokesman for the disaster agency, told reporters his team had been "preparing to send public warnings that were easy to understand" when the tsunami warning was "suddenly ended".

The communications ministry said repeated warnings were sent out to residents via text message, but Nugroho said the quake had brought down the area's power and communications lines and there were no sirens along the coast.

Indonesians took to social media to question the BMKG's move to lift the tsunami warning and a failure to release information in a timely manner.

"So upset.. the warning was lifted.. although a tsunami happened..." said one Twitter user @zanoguccy in a direct message to BMKG.

Shanghai, Jan 27: The death toll from a coronavirus outbreak in China rose to 81 on Monday, as the government extended the Lunar New Year holiday and more big businesses shut down or told staff to work from home in an effort to curb the spread.

Chinese Premier Li Keqiang visited the central city of Wuhan, the epicenter of the outbreak, as the government sought to signal it was responding seriously to the crisis.

The total number of confirmed cases in China rose about 30% to 2,744, about half of them in Hubei province, whose capital is Wuhan.

As worries grew around the world, Chinese-ruled Hong Kong, which has had eight confirmed cases, banned entry to people who had visited Hubei in the past 14 days. The ban did not cover Hong Kong residents.

The number of deaths from the flu-like virus in Hubei climbed to 76 from 56, health officials said, with five deaths elsewhere in China, including the southern island province of Hainan, which reported its first fatality on Monday.

While a small number of cases have been confirmed in more than 10 countries, linked to people who traveled from Wuhan, no deaths have been reported elsewhere.

Li is the most senior leader to visit Wuhan since the outbreak began. Clad in a blue protective suit and mask, he inspected efforts to contain the epidemic and spoke to patients and medical staff, the government said.

The government is extending the week-long Lunar New Year holiday by three days to February 2, in a bid to slow the spread of the virus. The Lunar New Year is usually a time for millions of people to travel, but many have had to cancel their plans because of travel curbs over the virus.

Incubation

Wuhan is already in virtual lockdown and severe limits on movement are in place in several other Chinese cities.

The city of 11 million clamped down further on Monday, announcing the suspension of visa and passport services until January 30.

Despite the curbs, the mayor of Wuhan said on Sunday that five million people had left the city for holidays and other reasons.

Images from Wuhan showing hospital corridors packed with people seeking treatment have circulated on social media, along with complaints of soaring prices for essentials such as vegetables.

Chinese leaders have urged transparency in the crisis, after public trust was eroded by the cover-up of the spread of Severe Acute Respiratory Syndrome (SARS), a coronavirus that originated in China and killed nearly 800 people globally in 2002 and 2003.

Much is not known about the newly identified coronavirus, including how easily it spreads and just how dangerous it is. It can cause pneumonia, which has been deadly in some cases.

National Health Commission minister Ma Xiaowei said on Sunday the incubation period could range from one to 14 days, and the virus was infectious during incubation, unlike SARS.

That compares with a World Health Organization (WHO) estimate of two to 10 days for the incubation period.

“Understanding the time when infected patients may transmit the virus to others is critical for control efforts,” the WHO said.

The virus is believed to have originated late last year in a Wuhan market illegally selling wildlife. It has spread to other cities, including Beijing and Shanghai, as well as more than 10 countries including France, Japan and the United States.

‘Overwhelmed’

Australia confirmed its fifth case on Monday involving a woman on the last flight out of Wuhan to Sydney before China’s travel ban.

Health minister Greg Hunt told the Australian Broadcasting Corporation (ABC) authorities aimed to get about 100 Australian children and young people out of Wuhan.

One father of two, Nathan Wang, told the ABC his wife was stuck in Wuhan with the children. “We absolutely want the children to come back, because hospitals in Wuhan are overwhelmed,” he said.

Airports around the world have stepped up screening of passengers from China, although some health experts have questioned its effectiveness.

Last week the WHO stopped short of calling the outbreak a global health emergency, but some health experts question whether China can contain the epidemic.

WHO Director-General Tedros Adhanom Ghebreyesus is due to travel to Beijing to meet officials and health experts.

Australia, France, Italy, Japan and the United States have all said they are working to evacuate citizens from Wuhan.

Some of China’s biggest companies have been affected, with hotpot restaurant chain Haidilao International Holding shutting branches nationwide from Sunday until Friday.

Gaming giant Tencent Holdings Ltd advised staff to work from home until February 7, and e-commerce firm Alibaba removed vendors’ offers of overpriced face masks from its online Taobao marketplace as prices surged.

Scientists predict the world may have a COVID-19 vaccine within one year or even a few months earlier, said the Director-General of the World Health Organisation even as he underlined the importance of global cooperation to develop, manufacture and distribute vaccines.

However, making the vaccine available and distributing it to all will be a challenge and requires political will, Tedros Adhanom Ghebreyesus said on Thursday during a meeting with the European Parliament's Committee for Environment, Public Health and Food Safety.

One option would be to give the vaccine only to those that are most vulnerable to the virus.

There are currently over 100 COVID-19 vaccine candidates in various stages of development.

Adhanom Ghebreyesus said the pandemic has highlighted the importance of global solidarity and that health should not be seen as a cost but an investment.

He added that all countries in the world must strengthen primary health care and crisis preparedness and stressed the need for EU leadership globally.

While the Director-General said the situation in the EU has improved significantly, he underlined that COVID-19 is very much still circulating globally, with more than four million new cases in the last month.

Many Members of European Parliament said that the global community must cooperate including in developing, manufacturing and distributing vaccines against COVID-19 and asked when a safe vaccine could be available.

Several Members of European Parliament underlined the importance of the WHO but also said it has made mistakes in its response to the pandemic.

The Director-General admitted everyone makes mistakes and informed the members that an independent panel will evaluate the WHO response to the pandemic to learn from any mistakes made.

It will start its work soon, he said.
