US: Sinkhole At Hillsborough Landfill Expands as Walls Collapse

The sinkhole is in an older part of the 3,300-acre tract at 1596 County Road 672, which opened as a landfill in 1984.
The sides of the sinkhole that swallowed up part of the Southeast County Landfill in Lithia four months ago collapsed last night. The avalanche of dirt did not widen the gaping 129-foot crater, but did deepen it by about 10 feet, officials said.

No one was injured and it is believed the dirt collapse was caused by the process that is aimed at filling the hole that is now estimated to be about 60 feet deep.

"We anticipated some movement, some additional sloughing of sidewall as a result of the pressure grouting," said Richard Siemering with HDR Engineering, which works with the Hillsborough County Solid Waste Department. He said the collapse delayed the process only a couple of hours until assessments could be made.

The grout is forced into the ground to shore up the bottom of the hole, he said, and it exerts pressure in all directions, including up. That can cause the bottom of the hole to shift and that's what caused the sides to fall in.

California, US: Landslide Forces Evacuation of Ranch



A landslide near the small town of Somis in Ventura County forced the evacuation of a residence and several horses.

According to the Ventura County Star, a piece of land about 200 yards long and 100 yards deep moved downhill about 100 feet on a ranch located in the 7600 block of Bradley Road. A residence and 63 horses were being moved.

The landslide started around 6:30 a.m. A local property manager reported seeing trees falling and sliding on a hillside and contacted the Fire Department.

Everett, Washington: Land Crack Appears, Neighborhood is Sinking


Image
EVERETT, Wash. -- People living in the Valley View neighborhood of southeast Everett are waiting and watching. A two story house on their block is tilted at a 20 degree angle and could collapse at any moment.

A crack in the earth that first appeared six weeks ago is now threatening about four homes. The City of Everett has "red tagged" the home on Burl which is collapsing. That means no one is allowed near the property.

A "yellow tag" was posted on two other properties where the land is giving way.

A surface slide in the area of Rob and Margaret Lund's house caused their deck and cement patio to completely collapse.

"There is nothing to stop this from happening again and again," said Rob Lund.

Recent heavy rains has caused the sliding to accelerate in the neighborhood. Neighbors said the problem appears to be getting much worse.

"If that house goes, the land will go with it," said Steve Mosman, who lives right next door to the collapsing home. "It would pull our land down with it. We just don't know what is going to happen."

Hole in Eton Close, Burton
A mysterious hole has caused 'anger and confusion' among residents after being left unfilled and unattended for almost a year.

The hole, which is the size of a small car, appeared in Eton Close, Burton, in April last year and despite repeated attempts by homeowners no-one will lay claim to the 'disaster'.

One resident, who asked not to be named, said: "No-one has any idea why the hole was dug in the first place - it just popped up all of a sudden.

"The situation just continues to go from the sublime to the ridiculous and it has now been left for more than 11 months - nearly a whole year. It has obviously caused problems for all of the people in the road as it is not a small hole - it is as big as a small car.

"Some residents received anonymous notes at the end of last year telling them to sort out the problem.

"The borough council has been involved and could not come out last year due to the bad weather.

The sudden appearance early in the morning of an enormous crack, measuring 100 meters wide and three kilometers long, caused confusion among residents of the Huacullani district in the Chucuito province, department of Puno.

The exact cause of the crack in the earth still unknown. Peru's geophysical institute ruled out the occurrence of an earthquake in the region, but what is clear is that the ground opened up and large blocks of earth can be observed scattered throughout the area.

The event, recorded Wednesday morning, caused the collapse of one house located in the rural community of Llorohoco. Four people managed to escape, but the youngest in the family, five-year-old Jean Carlos Vilcanqui Acero, is missing.

In a strange phenomenon, a black chemical substance gushed out from the earth, creating panic in Maddikera village in Kurnool district on Monday. Huge cavities also formed in the three acres of land owned by a farmer, Nagaiah, of Maddikere, about 100 km from Kurnool, soon after the black substance spewed out from beneath the land. Nagaiah said it damaged the soil. The nearby grass caught fire when the black substance spread like lava from a volcano. A cement electric pole in the vicinity collapsed. Nagaiah said he first saw the phenomenon two days ago. Officials rushed to the village to take stock of the strange occurrence. Experts said they would conduct studies to unravel the mystery behind the spewing out of the blackish material from beneath.

A section of the Coast to Coast Walk in Cumbria has been closed after a landslip near its starting point.

A 40m stretch of the cliff-top path at South Head at St Bees has collapsed and authorities say it is unsafe for the public to use.

Police were alerted yesterday evening and immediately cordoned off the area. Copeland Borough Council also alerted the Liverpool Coastguard office.

The local Coastguard sector manager went to the scene, along with Whitehaven Coastguard Rescue Team and officers from the council to assess the extent of the fall, which is right at the start of the 309km (192-mile) route, which runs from St Bees to Robin Hood's Bay on the North Yorkshire coast.

Liverpool Coastguard watch manager Paul Parkes said: "We would like to advise members of the public to take care when walking the stretch of cliffs between North Head and South Head at St Bees as part of this path has been closed off for safety reasons.

Heavy rains on Maui in the Waiehu area caused the ground to collapse, right next to a road's shoulder.

The huge hole is between Makaala Street and Wailupe Drive.

The sinkhole is 15 feet deep and up to 40 feet wide; it's big enough for a vehicle to fall into.

Sources say it's affecting drainage, fiber optics cables, and a sewer main.

State workers and county public officials will discuss repair efforts on Monday. Drivers are advised that authorities may close a lane along Waiehu Beach Road when repairs begin.
