Cyclone Amphan: Survivors return to face destruction left by storm

Millions of people across Bangladesh and eastern India are taking stock of the devastation left by Cyclone Amphan.

A massive clean-up operation has begun after the storm left 84 dead and flattened homes, uprooted trees and left cities without power.

India’s Prime Minister Narendra Modi has arrived in West Bengal state to conduct an aerial survey.

Authorities in both countries had evacuated millions of people before the storm struck.

Covid-19 and social-distancing measures made mass evacuations more difficult, with shelters unable to be used to full capacity.

Officials also said people were afraid and reluctant to move to shelters for fear of contracting the virus.

The cyclone arrived with winds gusting up to 185km/h (115mph) and waves as high as 15ft.

It is the first super cyclone to form in the Bay of Bengal since 1999. Though its winds had weakened by the time it struck, it was still classified as a very severe cyclone.

Three districts in India’s West Bengal – South and North 24 Parganas and East Midnapore – were very badly hit.

In Bangladesh, there are reports of tens of thousands of homes damaged or destroyed and many villages submerged by storm surges in low-lying coastal areas like Khulna and Satkhira.

The affected areas include the Sunderbans, mangroves spread over an area of more than 10,000 square kilometres that spans both India and Bangladesh – the swampy islands are home to more than four million of the world’s poorest people.

Those in the Sunderbans say it is too early to estimate casualties in the area, which is now cut-off from the mainland by the storm.

“There are houses which have collapsed and people could be trapped in them but we don’t know yet,” Debabrat Halder, who runs an NGO in one of the villages, told the BBC.

He recalls cyclone Bulbul in November 2019, which was followed by a huge incidence of fever, diarrhoea and flu, and is afraid that that the same may happen again.

And worse, he adds, is that the flooding from contaminated sea water, has likely destroyed the soil.

“Nothing will grow in this soil,” he says, adding that it will likely take years to convert it into fertile land again.

Kolkata, the capital of West Bengal, and one of India’s biggest cities has been devastated. Its roads are flooded and the city was without power for more than 14 hours.

The state’s chief minister, Mamata Banerjee, said the devastation in Kolkata was “a bigger disaster than Covid-19”.

But assessment of the damage is being hampered by blocked roads and flooding in all these areas.

Residents flee homes as subway tunnel collapses in China

  • Hangzhou subway operator says water seeped into underground construction site
  • Zhejiang’s capital was scene of subway collapse that claimed 21 workers’ lives in 2008

Homes in a major city in eastern China were evacuated on Wednesday after water seepage at a subway construction site caused a main road to cave in and cut a gas main.

Authorities in Hangzhou, Zhejiang province, said dozens of residents feared for their homes as buildings cracked and swayed from the cave-in.

Videos posted to the Weibo microblogging network showed yellow smoke engulfing the neighbourhood as the road fell below street level. Authorities said Hangzhou’s gas supplier managed to close off the mains.

Hangzhou Metro Group, the city’s subway operator and the company overseeing the network’s expansion from four lines to nine for the 2022 Asian Games, said on Weibo that water seeped into a tunnel that connected two stations in the centre of the city, leading to the collapse.

That caused a hole under the carriageway and took the pavement down with it. Hangzhou Metro said homes around the site were cleared and authorities were monitoring for further danger.

It was not known how many residents were affected, but no casualties were reported.

Most residents were put up in a nearby school until accommodation could be arranged, the City Express newspaper reported, adding that several truckloads of cement were poured into the hole.

Eight Chinese killed as road collapses near subway construction project
The road collapse in central Hangzhou was the latest in a series of subway construction accidents there – some of them deadly – in the past decade as China races to expand its urban rail networks.

In November 2008, 21 workers were killed and 24 were injured when a tunnel Hangzhou’s Line 1 collapsed beneath an eight-lane road and river water rushed in. A court sent eight people to jail for terms of between three and 5½ years for negligence at the site.

Two years later at the same place, a truck driver died and another was injured as a pit collapsed.

In 2016, four construction workers were killed when mud flooded a pit at a station on Line 4.

A cave-in similar to Wednesday’s collapse overturned a truck at a construction site near Hangzhou railway station this month, but no one was injured, Hangzhou Metro said.

According to the China Association of Metros, by the end of last year, more than 5,700km (3,540 miles) of urban railway had been built in 35 mainland cities, of which more than a third – 2,100km – was completed since 2015.

Block of flats collapses in southern China after ‘sinking into ground’

Emergency workers sealed off a building in the southern Chinese city of Shenzhen after it collapsed on Wednesday morning, local authorities said.

At around 11.20am, a block of flats in Luohu district suddenly sank into the ground and leaned to one side, the Shenzhen government said on Weibo, China’s equivalent of Twitter.

“Before it happened, the local community office heard noises coming from underground, and evacuated residents. Right now there are no casualties,” the Weibo post said. “The case is being investigated.”

In a short video published by state broadcaster CCTV, a residential building appears to have sunk into the ground and leans on the neighbouring building, with bricks and concrete strewn on the ground.

The area was closed off as police, ambulance crews and firefighters attended the scene.

The authorities also evacuated residents from surrounding buildings, moving them into temporary housing. A panel of experts began to investigate the cause of the collapse, while water, gas and electricity supplies were cut off in the area and construction work was halted as a precaution.

Earlier this month, a stadium in Shenzhen collapsed while demolition work was being carried out, killing three workers and injuring three. The part of the venue that collapsed had previously been used as a basketball court but was being renovated, with most of the interior having been torn down apart from a few pillars supporting the roof.

A trucker in eastern Zhejiang province collapsed a steel bridge by crossing it with a load weighing 50 times the bridge’s capacity.
The driver, surnamed Zhang, said he missed the two-tonne load warning sign when he tried to take dozens of concrete pipes to a construction site on Thursday morning, Kankannews.com reported.
He was not familiar with the area and used the bridge suggested by his digital map.
When the laden truck, weighing about 100 tonnes, was halfway across, the structure gave way, pitching the vehicle and its cargo into the water below. The driver managed to escape.
The truck’s load was 50 times the bridge’s breaking capacity. Photo: Weibo

Residents of a nearby village said a concrete bridge on the site fell into disrepair and was dismantled. It was replaced with a temporary steel structure a couple of years ago.

The new span was intended only for foot traffic and light vehicles, they said.

The pipes were recovered on Thursday evening.
