Landslides

"The causes of landslides are not a mystery to mankind. Layers of rock and soil such that rain running along a clay or rock layer can create a slippery surface for the weight of the layers above it is a common cause. A rock jumble from previous mountain building, broken or fractured rock easily dislodged. We have stated that the earthquakes man experiences between the periodic passages of Planet X can be considered aftershocks from the last passage, and this is true of landslides also. Mountain building rumples the landscape, so the land is not flat but has steep ravines and hill sides. Older mountain ranges are recognized for their rounded or smoothed appearance, because of frequent landslides distributing the rubble.

"As we approach another passage, another Pole Shift, the pace of landslides has picked up. Why would this be? Plates under pressure will put pressure on regions that contain rumpled hillsides and deep ravines, as these give more readily than strictly flat land, thus act as a weak link. In addition, due to the wobble, the weather has gotten more extreme, with drought and deluge increasing in extremes. Dry ground, suddenly flooded with rainwater needing to seek its level as runoff, will create internal water slides between the rock and soil layers that constitute the rumpled hillsides. Is there an early warning system that mankind could use? The trembles that soil about to slide emits could be detected, yes. These are not earthquakes, and have their own frequency. "

Woman dies after house demolished in landslide

Updated at 6:14 am today

A 63-year-old woman died when her house was demolished in a large landslide near Kaiteriteri in the Tasman district on Sunday.

Emergency services were alerted at 1.15pm and on arrival, found the badly damaged property on the Kaiteriteri-Sandy Bay Road.

One wall and the roof were all that remained of the house and neighbours were attempting to find the woman, who was the sole occupant of the property.

Her body was found partially submerged in the mud - police say the force of the landslide caused her to be ejected from her house.

Senior Sergeant Stu Koefoed says the house was levelled after a 200 metre slip came through the back of it.

"It was a slope and it's come straight through the house, so there's quite a bit of mass involved in the material that's come through the house - taken out most of the walls, the roof was left standing and she was found nearby."

Police have evacuated two neighbouring properties as a precaution and civil defence is managing road closures and monitoring river levels.

St John Tasman District operations manager James McMeekin says residents and emergency crews tried to help and although there was flooding it didn't stop emergency services from getting to the scene.

Several residents in the Tasman District have left their homes in case of flooding from the Riwaka River, although the levels in most of the area's other rivers are beginning to drop.

Ten millimetres of rain an hour is expected to fall on the district until at least midnight on Sunday.

Heavy rain, landslips, and flooding have closed a number of roads in the Tasman and Waitaki areas.

Drivers in the Tasman area can now use the Takaka Hill and can get to Marahau, although there are closures of minor roads, and the Tasman District Council says even roads which are open may be affected by land slips and debris.

Flooding in Canterbury and North Otago

The regional council in Canterbury says staff will be on duty there all night.

Its duty flood controller Tony Henderson says rain started on Saturday night in South Canterbury and North Otago, and is expected to cause problems on Sunday night.

He says streams and creeks are likely to overflow onto neighbouring roads, so residents should check for closures and warnings before setting out for work on Monday morning.

The council says the Western-Ngpara Road to the north-west of Oamaru is closed, which is expected to interrupt school bus services on Monday.

The regional council says there are no road closures in the North Otago area at 10pm on Sunday, although if a steady drizzle continues there, some surface flooding can be expected.

There are also 14 minor roads closed in South Canterbury.

MetService says the rain will ease in South Canterbury and North Otago by 6pm on Monday.

Landslide partly demolishes West Auckland house

Heavy rain has also affected Auckland with the fire service attending over 50 weather-related call outs.

Some people had to be evacuated from a house on Titirangi Beach Road in West Auckland, after it was partly demolished by a landslide but no one was injured.

Lines company Vector says about 650 households north of Auckland are still without power at 10pm on Sunday due to heavy rain and strong winds.

A Vector spokesperson says power has been restored to most houses that experienced outages earlier in the evening.

She says there are about 300 houses in Warkworth, another 300 in Waiwera, and about 50 in Long Bay that still have no power.

But she says lines staff are still hoping to restore power to those houses later on Sunday night.

Although sparse information is currently available, above are images of some of the landslides which occurred in several locations following today's severe quake.

A rockslide near the magnitude-6.3 quake's epicentre killed one person driving a car on a mountain road in Mountain Ali in the southern part of the island.

Rockslides at the scenic mountainous area near the epicentre also injured several people.

Landslide evacuates nearly 100 in Wellington - June 1

A massive landslide in Wellington has swept away backyards and left houses teetering on a cliff edge.

At least 90 people in the suburbs of Kingston and Berhampore were evacuated early this morning when a slip about 40 metres wide by 100 metres long came away from under houses in Priscilla Crescent.

Emergency services were called to the slip in Priscilla Crescent shortly before 5am this morning.

"The hill just slipped away and the rumbling and cracking sound of all the trees lasted for about a minute," one resident says.

"I thought it was a fire, but I looked outside, I couldn't see any flames but I could see the trees moving on the hill and the whole bank was slipping down the hill… The whole house was shaking and everything."

Around eight people have been taken to a Civil Defence center in Newtown. The majority of those evacuated are staying with friends or family.

A burst water main has been fingered as the cause of the slip, but council authorities have not confirmed this yet.

"There's still quite a bit of water coming out of the bank at this point in time which we are unable to establish where that's coming from," says Wellington senior sergeant Shannon Clifford.

Further minor slips have occurred over the morning, and with two houses on the edged of the newly-created precipice it is likely residents will be kept away for a while.

"While we were evacuating people further landslides occurred, whole pohutakawa trees were coming down in that landslide whilst we were pulling people out of their houses," says Mr Clifford.

Comment by Yvonne Lawson on May 26, 2013 at 4:43pm: Landslides and Large Dams - there may be trouble ahead....

The first is the global distribution of large dams – this is from the UN GrandD database, which provides information of large dams worldwide, mapped onto a global digital elevation model using ArcMap:

So each red dot here is a large dam (defined as having a storage capacity of greater than 0.1 cubic kilometres). The interesting thing here is the paucity of large dams in and around the Himalayan chain (and indeed the Andes). As I have shown before, the Himalayas are really the global epicentre for landslide activity, so this is the environment that requires the highest level of care with respect to landslide problems. The map below homes in on the Himalayas, again with a DEM as the backdrop:

The circles with dots in the centre are locations in which my database indicates there have been fatality-inducing landslides associated with large dams in the last ten years. These are mostly landslides at dam construction sites or landslides that have impacted the camps housing employees associated with dam construction or operation.

There are a surprising number of landslides given the numbers of dams in this part of the world.

One child missing, one killed in Minnesota field trip landslide

Jim Mone / AP

Rescue personnel gather near an entrance to Lilydale Regional Park above the Mississippi River during a suspension of search efforts to find a fourth child missing after a landslide swept over a group of children on a fourth grade field trip Wednesday, May 22, 2013, in St. Paul, Minn.

By Matthew DeLuca, Staff Writer, NBC News

Authorities said they would continue their search Thursday for a Minnesota child who remained missing after a gravel slide swept several children on a school fossil-hunting trip into a pit, killing one.

The fourth-graders from a St. Louis Park elementary school were hiking in Lilydale Regional Park on Wednesday when a steep slope soaked by rain gave way, authorities have said. Two trapped children were dug out by firefighters who clawed away gravel with their hands and shovels, they said.

“It appears they were walking along and the ground, after the rain we’ve had, was so soft and it gave way and they fell into what became a hole and the earth came on top of them,” St. Paul Fire Marshal Steve Zaccard said at a news conference, according to NBC News affiliate KARE.

An emergency worker attends to a person on a stretcher, being evacuated out of a rockslide site by helicopter, on the West Side of St. Paul, Wednesday, May 22, 2013.

One of the children pulled from the pit later died, and has not yet been identified by authorities.

“The slide had fallen down on top of them," Zaccard said. “One was partially buried, one was completely buried.”

The search for the missing student was suspended overnight as rescuers battled worsening conditions.

“Water is flowing right into the hole making it extremely dangerous for rescuers to work anymore,” Zaccard said. “We are working with our partners in Parks and Public Works to make the scene safe for what’s become a recovery effort for what might be a fourth victim.”

A man who identified himself as the missing child’s uncle said the student “liked geology,” according to the Minnesota Star Tribune.

“Thoughts and prayers go out to the families of the children and to our first responders who continue to deal with the situation as it develops,” said St. Paul Mayor Chris Coleman.

Comment by Howard on May 23, 2013 at 3:38am: Alberta Highway Near Peace River Collapses (May 18)
Highway 744, Judah Hill road just south of Peace River has been closed due to a collapse.

Alberta Transportation discovered the slide during a routine inspection of the area and was in the process of forging a detour when the rest of the road collapsed shortly after midnight May 18. The area was deemed hazardous and the entire road remains blocked off.

Traffic entering and exiting the Town of Peace River via Highway 744 is detoured to Highway 2 and Highway 683. Due to the location and severity of the slide, the length of time the road closure will be in effect is unknown.

La Prairie Works Inc., the Alberta Transportation contractor responsible for the maintenance of the highway in the area, continues to closely monitor the slide’s activity.

“Until we get that initial assessment done we really don’t know what we’re looking at," according to Acting Operations Manager Mae Stewart.

This is the first serious collapse the road has had.

Landslides surge in Western North Carolina

Pressure builds for regulations

FRANKLIN — It took about a month for the small crack in front of Mike Boggan's mountainside home to turn into a foot-high drop off.

A county inspector told him not to worry about it at first. Today his house stands condemned and Boggan is living with friends, the latest victim in a string of landslides across Western North Carolina.

In the last six months, landslides, mudslides and rock slides in WNC and east Tennessee have destroyed parts of three major highways and damaged at least five houses, Boggan's included.

Governments in both states are spending nearly $20 million to repair the damage, with the biggest expense being the rockslide on Interstate 40. Repair work on that stretch near the Tennessee line should be done this month.

The increase comes during one of the wettest years on record and during one of the hardest winters.

It also comes as local and state lawmakers feel increasing pressure to develop regulations for building on mountainsides.

Worried neighbors

Boggan is not the only one on his street who doesn't know what to do.

Varshana McGaughey and her husband built their home nearby two years ago and worry about the ground's stability.

"My concern is about the stability of the whole mountain," she said, "and what will happen two months down the road or two years down the road."

A slow-moving landslide of about 5 acres made living in Boggan's house too dangerous .

McGaughey hasn't seen problems as severe, although part of her lot and a corner of her driveway did sink recently. It's being repaired with compacted fill dirt on her builder's advice. The cause hasn't been determined.

State geologists have looked at Boggan's property and surveyed land being cleared nearby for the Craftsman's Village development, which was to have homes and shops.

The mountain's soil is decomposed bedrock so soft it can be removed with a hand trowel, said Rick Wooten, a senior geologist with the N.C. Geological Survey.

"It has the worst of both worlds," he said. "It has the plane of weakness it inherited from the bedrock, but the mass has weathered to the point where it's lost the strength of what it had."
