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. "

At Least 13 Sherpas Dead as Avalanche Sweeps Mount Everest
An avalanche swept down a slope of Mount Everest on Friday along a route used to ascend the world's highest peak, killing at least 13 people in the mountain's deadliest disaster.
NBC News confirmed that all of the dead were Sherpa guides.
The guides had gone early in the morning to fix the ropes for hundreds of climbers when the avalanche hit them just below Camp 2 around 6:30 a.m. local time, Nepal Tourism Ministry official Krishna Lamsal told The Associated Press.
Tilak Ram Pandey, an official at the ministry's mountaineering department, later told Reuters that some other people were thought to be missing.
Hundreds of climbers, their guides and support guides had gathered at the base camp, gearing up for their final attempt to scale the 29,035-foot peak early next month when weather conditions get favorable. They have been setting up their camps at higher altitudes and guides fixing routes and ropes on the slopes ahead of the final ascend to the summit in May.
As soon as the avalanche hit, rescuers and fellow climbers rushed to help. A helicopter was also sent.
Ang Tshering of the Nepal Mountaineering Association said that the area where the avalanche occurred is nicknamed the "popcorn field," which is just below Camp 2 at 21,000 feet.
Nepal had earlier announced several steps this year to better manage the flow of climbers, minimize congestion and speed up rescue operations. The preparations included the dispatch of officials and security personnel to the base camp located at 17,380 feet, where they would stay throughout the spring climbing season that ends in May.

More than 4,000 climbers have scaled the summit since 1953, when it was first conquered by New Zealander Sir Edmund Hillary and Sherpa Tenzing Norgay. Nearly 250 others have died on the mountain.
The worst recorded disaster on Everest was on May 11, 1996, when eight climbers were killed in one day because of a storm near the summit. Six Nepalese guides were killed in an avalanche in 1970.

A Wyoming landslide about the size of two football fields continues to slowly move down a hill, causing nearby residents to evacuate - and splitting apart one home.
48 Jackson residents as well as several businesses were evacuated, according to a CNN report. The residents checked in to a Red Cross station.
So far, only one unoccupied home has sustained any damage. The house is directly atop the slide zone and its interior wooden floor seems to be splitting in two, Assistant Town Manager Roxanne Robinson told the channel.

'What really struck me is the wood flooring, which is separating,' Robinson said. 'One half of the house looks like it's on side of the slide area and the other half is definitely at the crest of the slide.'
Robinson also said that the home's driveway is cracked by a 6-1o-12-inch upward fissure.
According to CNN, the landslide moves slowly enough for officials to observe ground cracks and monitor its path each day.
Officials say the landslide continues to shift, making it unsafe for residents of mostly apartments to return home even though the apartments are outside the area where the highest risk of a collapse exists.
'The cracks continue to widen and deepen,' Robinson said on Saturday. 'If it keeps sliding every day, other complications could arise.'
No one can say right now when residents might be allowed back home, Robinson said.
Robinson said portable water tanks were being placed on the unstable hill in case a fire breaks out. The shifting hill has broken permanent water lines, and the temporary water lines that have been put in place don't provide sufficient pressure for firefighting, she said.
There are power lines on the hill that could be brought down by the slide and spark a fire.
'It's definitely dry on the hill, and we need to have a water supply that we can access in a hurry should it be necessary,' said Mike Moyer, an official with the local incident command team.
At the foot of the slide zone, two restaurants, a liquor store and a just-built Walgreens remain closed amid a slim but persistent risk the hill could collapse suddenly.
A geologist put the risk of sudden collapse at just 5 percent.

YOSEMITE NATIONAL PARK, Calif. (AP) — Officials at Yosemite National Park say a massive amount of rock has fallen from a cliff, closing a hiking trail.
The National Park Service said Monday that nobody was hurt when the 16,000 tons of rock fell 500 feet from a cliff near Hetch Hetchy Reservoir on March 31. Many boulders tumbled into the water.
Officials say the rock crashed down from a cliff east of Wapama Falls. The rock broke into numerous boulders, crushing trees and sending up a small dust cloud.

Land Fissures in Utah (Mar 31)
Cracks in the earth and settling of the ground in areas of the Cedar Valley were the focus of a special Central Iron County Water Conservancy District work meeting March 27.
A just-released report from the Utah Geological Survey (UGS) shows the ground has been sinking.
The comprehensive 116-page report presents the results of an investigation of land subsidence and earth fissures in Cedar Valley, Iron County, Utah
The settling, called subsidence, and the cracks, called fissures, represent a major problem.
“Because the ground does not subside evenly, earth fissures or deep ground cracks, have formed,” said Tyler Knudsen, UGS project geologist.
The subsidence has caused a total of more than eight miles of earth fissures to form.
The earth fissures have been most noticeable in a partially developed subdivision in Enoch, Utah.
Fissures in this area have destroyed pavement and reversed the sewer system in the Parkview Subdivision, which was not completed and contains pavement, sidewalks and one uninhabitable house.
The UGS believes one fissure has extended into the inhabited Legacy Estates subdivision by 240 feet, and comes within 50 feet of a home.

Aerial photos of massive mudslide in Washington state
http://www.nbcnews.com/news/us-news/huge-washington-landslide-kills...Huge Washington Landslide Kills Three and Dams a River - March 22, 2014
Three people were killed and eight injured in a mile-long landslide north of Seattle that demolished at least six houses Saturday morning, blocked roads and dammed a river, bringing fears of a major flood, officials said.
“First responders heard someone inside screaming for help” as the landslide swept a house onto a road in the community of Oso in Snohomish County at approximately 11 a.m. (2 p.m. ET) Saturday, said Washington State Patrol Trooper Mark Francis.
Among the injured was a 6-month-old in critical condition, according to Harborview Medical Center in Seattle. The hospital was also treating a 37-year-old male and an 81-year-old man both in critical condition and a 58-year-old man and a 25-year-old woman in serious condition, said spokeswoman Susan Gregg.
Another man brought to Harborview died of his injuries, Gregg said.
The search for survivors continued into the night. Snohomish County Fire District 21 Chief Travis Hots said at a news briefing late Saturday that people were still yelling for help, NBC station KING5 of Seattle reported.
Earlier, the search involved the Snohomish County Sheriff’s Office, Washington State Patrol, Washington Department of Transportation, and Army Corps of Engineers. The Department of Emergency Management, U.S. Navy and local fire departments were also involved in the search, the DOT said.
Portions of State Route 530 were shut down, and the monster mudslide “diverted part of a local river, which started a flood in the area,” Francis said.
"Very high potential for fast upstream, downstream flooding. Prep now in case you have to leave quickly," the Snohomish County Government warned in a tweet four hours after the initial slide.
Officials said reverse 911 calls were sent warning residents of the danger of flooding from the North Fork Stillaguamish River upstream from the slide, as well as the possibility of flooding 12 miles downstream to Arlington should there be a catastrophic breach by the river.
Snohomish County officials said in a tweet that hundreds of people could be at risk in the flood plain.
"Anyone along the flood plain of the Stillaguamish between Oso and Stanwood should leave," Gov. Jay Inslee said in a statement that offered condolences to the victims' families.
The commander of the Snohomish County Search & Rescue team told NBC affiliate KING5 that the slide is the largest he's seen in the area in 30 years.
Francis said Snohomish County rainfall accumulations have broken records for the month of March.
Aerial photos showed a huge chunk of hillside had let loose, falling hundreds of yards into the valley.
