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. "

Frantic rescue efforts underway following Himalayan glacier disaster
https://www.accuweather.com/en/weather-news/death-toll-feared-to-ri...
An enormous search and rescue effort continued Monday in northern India one day after a calamitous glacier collapse occurred in the Himalayan Mountains.
A piece of the Nanda Devi Glacier broke off on Sunday, allowing floodwaters to spill down the mountainside and into a valley. The wall of water destroyed one hydroelectric dam and damaged another before surging downstream.
At least 31 people have been killed by the flood, and officials fear the death toll could rise.
More than 2,000 members from the military and police groups joined the search and rescue efforts in India's northern state of Uttarakhand, the Associated Press reported Monday. The operation was focused on 37 workers trapped in a tunnel that filled with water and debris in the flood.
“The tunnel is filled with debris, which has come from the river. We are using machines to clear the way,” H. Gurung, a senior official of the paramilitary Indo Tibetan Border Police told the AP.
On Monday, 12 workers were pulled from a tunnel at the construction site of the Dhauliganga dam.
The death toll is expected to climb as officials continue to search for bodies at the two hydroelectric dams that were damaged as well as in the bodies of water downstream.
After damaging two hydroelectric dams, floodwaters raced down the mountain, prompting evacuations of villages located along the banks of the Alaknanda and Dhauliganga rivers, according to the AP.
There are reports of damaged homes along the two rivers, but it is unclear if any residents are missing, dead or injured as officials continue to investigate.
Government officials airdropped food packets and medicine to at least two flood-hit villages, the AP reported.
According to Reuters, which cited an unnamed government official in India, many local villagers had been able to escape the imminent disaster as soon as they heard the loud rumble of water roaring down the mountain.
“The workers in the tunnel may not have heard anything and got stuck,” the official told Reuters.
India Prime Minister Narendra Modi said he was closely monitoring the situation shortly after being informed of the incident.
“India stands with Uttarakhand and the nation prays for everyone’s safety there,” he said on Twitter. "I have been speaking to senior authorities and getting updates on NDRF deployment, rescue work and relief operations," he added.
Dry and tranquil weather conditions allowed rescue and recovery operations to continue without disruption on Monday. A passing shower cannot be completely ruled out on Tuesday and Wednesday. However, no major precipitation is anticipated.
AccuWeather meteorologists also warn that temperatures trending higher across northern India in the coming days could cause some snow to melt along the southern slopes of the Himalayas, which can cause rivers to rise and lead to flash flooding.
Just two days before this disaster, a large avalanche occurred on the glacier, which added stress to the ice, an SDRF official told the Indian Express.
On Monday, a team was sent to the glacier to investigate the reason why a large piece broke off.
This stretch of the Himalayan Mountains in northern India is home to a chain of hydropower projects on several rivers and tributaries across the region. Authorities said they were able to save other power units downstream because of timely action taken to release water by opening gates, the AP reports.

Norway landslide: Houses buried in Gjerdrum village near Oslo
A landslide in a Norwegian village has injured 10 people, left 21 unaccounted for and buried houses under what looks like a huge slick of mud in a gully.
About 500 people have been evacuated from the village of Gjerdrum, which lies some 25km (15 miles) north-east of the capital, Oslo.
One person was seriously hurt, reports say.
"Police are designating this as a disaster," head of the local police operation, Roger Pettersen, said.
"There are dramatic reports and the situation is serious," he said, adding that people had called emergency services saying that their whole house was moving.
Several people were reported to be trapped and some were said to have managed to phone relatives appealing for help.
Of those still missing, police said in a statement: "We don't know if these people are in the landslide area, if they are away on holiday or in another way unable to contact police."
The landslide struck in the early hours of Wednesday and is reported to cover an area of 210,000 sq m (2.3m sq ft).

Landslide triggers massive debris cascade in remote part of B.C. coast
Force of event in November equivalent to a magnitude 4.9 earthquake, scientists say
Scientists suspect a massive landslide scoured the Elliot Creek bed, creating this canyon, after an initial outflow into a glacial lake triggered an 'outburst flood.' (Bastian Fleury/49 North Helicopters)
A massive landslide on the B.C. coast about 220 kilometres northwest of Vancouver in November propelled approximately 7.7 million cubic metres of debris into an ocean inlet, reshaping a swath of coastal landscape.Scientists say the force of the event was equivalent to a magnitude 4.9 earthquake — and was about one-sixth the size of one of Canada's biggest landslides in 1965.
The so-called Hope Slide near Hope, B.C., in January 1965 was one of the largest in Canadian history, sending 47 million cubic metres of rock, mud and debris across Highway 3.
But last month's slide into Bute Inlet went almost unnoticed for weeks, as it was in such a remote area.
Scientists say the initial slide happened on the mainland about 110 kilometres northeast of the closest city, Campbell River on Vancouver Island, when a steep slope let go and sent debris into a swollen glacial lake.

Geologists and seismologists believe that initial slide caused what they refer to as an "outburst flood," that happened when the lake overflowed in a sudden wave down the mountain around 6 a.m. PT on Nov. 28.
'Cascade of hazards'
"This is the kind of thing that I get excited about," said Daniel Shugar, an associate professor in the department of geoscience at the University of Calgary.
"It's quite an interesting hazards cascade or sort of domino series of events. One landslide triggered a displacement wave — like a tsunami in the lake — which cut down through the moraine [a debris accumulation] that was damming that lake to cause this outburst flood and then this turbidity current in the ocean."
Shugar suspects heavy rain caused the initial slide on the slope that had shown instability before. The sudden burst of water from the lake created a knock-on effect propelling millions of cubic metres of mud and debris and scouring out Elliot Creek into more of a canyon.
"This slurry of material, almost like wet concrete, carrying boulders would have been washing down Elliot Creek and then the Southgate River and would have uprooted trees and deposited them into Bute Inlet," said Shugar.
Watch | Footage from helicopter pilot's camera as he discovers the magnitude of the debris field:
Helicopter pilot Bastian Fleury flew to B.C.'s Southgate River on Dec. 10, 2020, to investigate why trees and logs were floating down the nearby Bute Inlet. The pilot found evidence of a massive landslide that had carved the creek bed into a canyon. 0:52
It has been a rainy fall, with Rivers Inlet residents forced out for fear of landslides in late October. But, other than the odd lodge, there are rarely people near the area where this slide was triggered, especially in winter.
Curious helicopter pilot discovers size of landslide
On Dec. 10, with logs and trees floating into Bute Inlet, a helicopter pilot decided to fly over the remote area near the Southgate River — about a 15-minute flight from Campbell River — looking for the source of the destruction, at first following the Southgate River, then the creek.
Bastian Fleury of 49 North Helicopters has flown for a decade, so he's seen a few slides. But nothing like this.
"It was just a weird sight. I've seen landslides but that's a big, big one. We knew something big happened," he said.
Fleury could not fly far enough to find the source, because the weather was hazardous, and visibility higher up wasn't great.
But he suspected that it was somehow related to the glacial lakes fed by the Homathko Icefield, one of the largest in the southern half of the Coast Mountains.
In Fleury's footage, as the helicopter flies along the former creek bed, it's clear that whatever force came down the mountain was powerful. The shallow creek bed has been transformed into a steep-sloped canyon. In other still photos along the river, odd islands of spindly trees are precariously perched, as a mud river continues to flow by.
"It's really crazy," said Fleury, who is looking forward to flying up farther to see the initial site where the slope collapsed, when the weather co-operates.

Six people missing after Alaska landslide (nbcnews.com)
Six people missing after Alaska landslide
December 2 2020
The landslide in southeast Alaska followed heavy rains and destroyed several homes.Six people are unaccounted for in Alaska after a large landslide following heavy rains, officials said.
Nine feet of mud and trees covered the area after the major landslide, which happened sometime before 1:50 p.m. Wednesday in Haines, state troopers said in a statement. At least four houses were destroyed in the community of around 2,000 people in southeastern Alaska.
There had been smaller landslides, but the biggest happened Wednesday afternoon, Haines Mayor Douglas Olerud told NBC affiliate KTUU of Anchorage.
"We’ve had significant rainfall on top of frozen ground and snow," he said.
Search-and-rescue operations were suspended for the evening because of unstable ground, state troopers said, but more help was set to arrive Thursday.
The Coast Guard, as well as mountain rescue personnel and medics from Juneau either have arrived or would be arriving Thursday, officials said.
More than 9 inches of rain fell on the Haines airport over 36 hours, National Weather Service meteorologist Gregg Spann said Wednesday evening, and another inch or inch-and-a-half is expected before the storm is over.
A flash flood watch was in place for the Haines area through Thursday morning.

At Least Twelve Dead In The Landslide Of The Peñas Blancas; Feared Up To 30
Nov 18 2020
The landslide of approximately a length of 1,000 meters and a width of 200 meters occurred on Tuesday. Search and rescue efforts continue. The unofficial death and missing number is much higher.
TODAY NICARAGUA – At least twelve people died in a landslide in the Macizo Peñas Blancas, in the municipality of El Tuma-La Dalia, in northern Nicaragua.
On Wednesday afternoon, 12 deaths have been confirmed, while another 19 people have been rescued alive.
At least 15 others have been reported missing.
The tragedy occurred in the Los Roques sector, in the San Martín de Peñas Blancas community, in the Matagalpa department (province).
Members of the Nicaraguan Army, Police, Fire Department, Minsa, Comupred and Codepred participated in the rescue efforts.
Authorities indicated this Wednesday that a brigade made up of 100 people are involved in the search and rescue in an area that is difficult to access due to the ravages of Iota.
The Army is using dogs to search for any survivors.
The government assures that the families in “previous years received a proposal to relocate a place because they were in a risk zone, but they did not accept, they were also advised to evacuate before the arrival of the hurricane, but they decided to stay.”
The Bishop of the Diocese of Matagalpa, Monsignor Rolando Álvarez, lamented the tragedy and assured that priests are moving to the area to make themselves available.
“Deep sorrow for what has happened to us in the Macizo Peñas Blancas, between La Dalia and Rancho Grande. At this moment our priests are mobilizing to that area and we are making ourselves available to all who are affected. I will keep you informed,” tweeted the Monsignor.

Video: Concerns over massive peat slide at Co Donegal bog
16 November, 2020 01:00CONSERVATIONISTS have expressed concern about a dramatic landslide resulting from peat slippage at a bog in Co Donegal.
Footage of trees being swept away as tonnes of peat slipped downhill near Meenbog Wind Farm, close to Ballybofey and the Co Tyrone border, went viral at the weekend.
The wind farm is owned by Invis Energy who said: "Invis Energy, owner of the Meenbog wind farm, confirms that a peat slippage occurred at the site. There is no risk to public health. We are working with the relevant authorities to fully address the matter. We are grateful to the local community for their continued support."
The local Gweebarra Conservation Group warned that thousands of tonnes of peat and conifer trees potentially entering the Mournebeg River was "a catastrophe for spawning salmon and trout".
The group also said it "remains to be seen" if drinking water would be affected and warned that as bogs are 'carbon sinks', an unknown quantity of carbon would have been released into the atmosphere.
A spokesperson for Irish Water said there was "no immediate concern for water services in the Finn Valley", due to the displaced peat and trees entering the river downstream of the Lough Mourne reservoir.
Both Donegal County Council and cross-border body The Loughs Agency are also investigating the incident near Barnesmore Gap.
Meanwhile, Derry City and Strabane Sinn Féin councillor Kieran McGuire urged NI Water to liaise with their counterparts in Irish Water to "urgently assess the situation" and ensure drinking water in both Co Donegal and Co Tyrone is safe.
He added: "This is an extremely worrying and developing situation."
