House left dangling after cliff gives way
11 June 2014 Last updated at 20:58 BST

A luxury house in Texas has been left dangling over the edge of a cliff after the ground under its foundations eroded away.

The house, which is on Lake Whitney southwest of Dallas, has been circled by a local TV news helicopter waiting for it to fall into the water below.

The lake is about 50 miles south of Fort Worth. The bedrock appears to be chalk. I'd guess the chalk was eroded by eg a leak from drains. The house is on a cliff edge, so stand by for a dramatic and expensive splash!

Dangling house burnt down for 'safety'
13 June 2014 Last updated at 21:43 BST

Officials in Texas have set fire to a luxury lakeside home that was dangling over the edge of a cliff.
Part of the house fell into the lake on Tuesday - now it has been burnt down to stop the rest of it plunging into the lake.
The owners of the house - which was nearly 50 metres from the cliff edge when it was built - have already abandoned it.

Undercliff Drive repair 'could cost £20m'

Repairing an Isle of Wight road affected by a landslip could cost up to £20m, a report has said.
The ground at Undercliff Drive, on the island's south coast, is continuing to subside more than four months after nine houses there had to be evacuated.
The instability followed heavier-than-average rainfall during the winter.

Six options, including pedestrian-only access, a temporary low-cost road and opening the road in one direction, are due to be discussed by the council.

Nine properties between Niton and St Lawrence were left landlocked and inaccessible when the landslip started in February.
One of the affected properties has been declared unsafe by the council's building control section. Two of the properties are still occupied.

A report to the Isle of Wight Council prepared by Island Roads said ground movement had slowed, but not stopped.
It stated fully repairing and re-opening the road from Ventnor to Niton would cost anything from £6m to £20m.
Jon Gilbey, of Isle of Wight Council, said the options needed to be "fully and properly costed".
"The welfare and concerns of the affected residents remain paramount. We are doing all we can to reach a decision on the road's future as soon as possible," he added.

Island Roads is a partnership between the council and private companies aimed at maintaining the Isle of Wight's highways under a Private Finance Initiative scheme.

Branksome Dene garden collapses into car park

Part of a private garden has collapsed into a beach car park in Dorset.
Tonnes of soil, vegetation and debris fell into Branksome Dene Chine, Poole, as a result of the landslip on Thursday.

Borough of Poole council, which owns the car park, has cordoned off the area while investigations take place. The rest of the parking remains open.
No-one was injured in the collapse which happened at a property behind Sandbourne Road on Thursday morning.

Simon Legg, street scene operations manager, Borough of Poole said: "We are aware of the landslip at Branksome Dene Chine and have cordoned off a small section of the car park.
"A surveyor has visited the property owner to assess initial damage and we understand the owners are seeking advice from structural engineers.
"A further assessment of the stability of the embankments will be undertaken prior to the removal of any material from the car park."

The stretch of coast is prone to landslips, especially following spells of heavy rain.
In February, a 20m wide (65ft) strip of cliff face fell onto the promenade between Bournemouth and Boscombe piers.

Crumbling cliff leaves care home teetering on the edge
Just days after moving in, elderly residents at the Cheval Roc Residential Home on Jersey wake up to a terrifying scene
By Agency
3:53PM GMT 14 Mar 2016

A care home was left teetering on the edge of a sheer cliff face after tonnes of earth fell away in a landslide.
Elderly residents at the Cheval Roc Residential Home on Jersey woke up to the terrifying scene on Thursday last week, just days after they moved in.
The building was left inches from disaster after heavy rain, rough seas and 75mph winds battered the cliff face, causing land and mud to be swept away.

Three rooms closest to the edge will remain unoccupied as residents move in to other parts of the newly-refurbished home, at Bonne Nuit harbour in Saint John, Jersey.
The ten pensioners currently living at Cheval Roc have been given the all-clear to remain there as the damage is assessed.
Engineers said there was no threat to the structure of the building, which was originally around five metres from the edge.
Further work may need to be carried out to reinforce the cliff face.

Jersey resident Chris Brookes, 43, a retail manager, took photos of the damage using a drone.
He said: "I couldn't believe what I saw. It was very scary. This is Mother Nature hitting back.
"It is awful. Apparently the home is structurally safe but how safe can it really be? It has only just been renovated.
"Another home in Jersey is being closed down and a lot of the residents are being moved to the new one.

etc...

This thread looks neglected (although we do have two landslip threads). But now I can offer, not one, not two, but THREE landslides!
Warning as three landslides hit coast of north Cornwall
8 April 2016

Chunks of cliff weakened by prolonged rainfall have collapsed at three separate sites.
Cornwall Council has warned of more possible landslides following the collapses along the north coast of Cornwall in the past week.

The cliff gave way near Treyarnon on Thursday with earlier cliff falls near Trevone and Morwenstow.
The South West Coast Path has been moved further inland in the affected areas.

Leroy Chandler, who runs the Trethias Farm campsite at Treyarnon, said: "There are still pieces half-way down the cliff that haven't gone all the way yet."

A Cornwall Council spokesman said the public should "be vigilant and avoid resting underneath cliffs or straying towards the seaward side of the coast path".

Another version, and some new pics:
These dramatic pictures show the scene after two major cliff falls near Padstow
By CGBen | Posted: April 08, 2016

Cormac engineers were called to Fox Cove near the Trethias Farm caravan park just before midday.
Leroy Chandler, 34, who runs the caravan park with his parents, said he heard the first fall.
"I was in the adjacent field," he told the Cornish Guardian. "I heard it go, and saw a huge cloud of dust appear in the sky.
"I'd say at least 120 tonnes of material came down".

The first sign something was wrong appeared earlier in the day, when Leroy received [a picture of cracks in the coast path] in a text message.
"The first thing I thought was 'That wasn't there yesterday'".
Leroy contacted the countryside team at Cornwall Council, who were quickly at the scene.

Leroy, who also volunteers for Padstow Coastguard, took to social media to issue a warning that people should steer clear of the area.
Meanwhile Cormac's engineers began to secure the site.
"They were quite concerned, as I was, with the cracks in the cliff path," said Leroy. "They secured it off with rope pretty quickly."


Leroy said: "While I was showing the guy from Cormac, the second part of the cliff fell.
"I've seen cliff falls in this area, but he'd never seen one actually happen before."

Leroy described the sight and sound of hundreds of tonnes of dirt and debris crumbling into the sea.
"It's like a slide," he said. "You get small amounts running off, then it starts tumbling. Then because the cliffs are at a gradient, some of it falls outwards in the same way a building would collapse.
"But because it's all fractured slates, it's not a rumbling sound. It sounds almost like tonnes of mussel shells being poured out."

As the volunteer responsible for Padstow Coastguard's Twitter account, Leroy repeated his earlier warning that people should avoid the area.

He said: "It's lucky that we're coming to the end of the Easter period now. It was a cold and wet morning and there weren't many people around".

This seems to be the main landslip thread. I would not want to have been in that first car.

At least 48 people have been killed in a landslide at a vast rubbish dump on the outskirts of Ethiopia's capital Addis Ababa, officials say.

They say dozens of people are still missing since the landslide on Saturday night at the Koshe landfill. A resident said 150 people were there at the time.

A number of makeshift houses are now buried under tonnes of waste.

The area has been a dumping ground for Addis Ababa's rubbish for more than five decades.

A city spokeswoman told AP news agency that many children were among the dead.

There are fears the death toll could rise further. ...

Here is something that I thought of, and have heard concerns expressed about the potential for one occurring as a result of a landslide especially from the Canary Islands.

https://en.wikipedia.org/wiki/Megatsunami#Canary_Islands

It brings to mind the disastrous tsunami of 1700 in Japan. That resulted from an earthquake in what is now the Pacific Northwest of the USA.

I'd just wait for it to fall off the edge, then buy the land for the suddenly-low market value.

This new beach cliff collapse incident just north of San Diego is likely a harbinger of others that will inevitably follow ...
Collapsing California cliff claims 3 lives along beach

A popular surfing beach was closed Saturday after a cliff collapsed, sending tons of sandstone onto beachgoers and killing three people.

A 30-foot-long slab of the cliff plunged onto the sand near Grandview Beach north of San Diego. A KNSD-TV helicopter captured footage of beach chairs, towels, surf boards and beach toys strewn about the sand.

Other beachgoers and lifeguards at a nearby tower scrambled to the towering pile of debris, which was estimated to weigh tens of thousands of pounds, to help dig out victims. ...

A woman died at the scene, and two more people later died at hospitals. Another person was taken to a hospital, and a person who had minor injuries was treated at the scene, according to statements from the city. ...

Cliffside collapses are not unusual as the ocean chews away at the base of the sandstone, authorities said. Some beach areas were marked with signs warning of slide dangers.

Several people have been killed or injured over the years in bluff collapses. The Tribune reported that Rebecca Kowalczyk, 30, of Encinitas died near the same area on Jan. 16, 2000, when a 110-yard-wide chunk of bluff fell and buried her.

Bluffs give way four to eight times a year in Southern California, but “nothing of this magnitude,” said Brian Ketterer, southern field division chief of California State Parks. ...

Here's a New York landslip / landslide that's threatened multiple homes.
A landslide in New York state leaves homes dangling inches away from a giant crater

A landslide left a dozen people displaced after their homes came dangerously close to being destroyed.

Pictures of the scene on Sunday in Waterford, New York, show one home dangling off the edge of a cliff and other homes mere feet away. Initially, seven homes were evacuated, according to Waterford Fire Chief Donald Baldwin. But after engineers inspected the area, that number was reduced to three.

No one was injured and no structures were destroyed.

Engineers and other city officials are continuing to monitor the scene because the slide is still moving, according to Baldwin. Stakes have been placed into the ground to see the rate at which it is moving, according to CNN affiliate WTEN.

The cause for the landslide is unknown, Baldwin said, but he noted that the area used to be a gravel pit.

Is it just me or are a lot of these problems caused by the modern desire for clifftop property?

The cliffs would erode anyway.

Maybe it's different in other countries but in the US, local officials don't do a good job of zoning hazardous lands for safe uses. They will let people build at their own risk if it gives them tax money - penny rich, pound foolish, I think. That, and people insist on their right to do really dumb things. Finally, with cliffside properties, sometimes the distance seems far enough but a few storms, other events, or just time chews it away gradually until adequate support is gone.

In Cornwall you can always tell the older properties.

Hidden in the dip and sheltered. Cornwall has a mild climate but its also stormy.

Modern houses are often on the top.

I knew someone who bought a house facing right out into the Atlantic.

He sold up pretty quick.
