I am just beginning to search sinkhole reports through other languages. Via a link someone provided me to a Polish website I found sinkholes I'd never heard about before, some more interesting than others, and many familiar sinkhole events. The sinkhole in Brazil was one of them. There is just nothing like seeing it as it happens (was caught on cctv.) This one is rather dramatic, occurring in Sweden in 2012. Huge sinkhole in Sweden ![]() Phenomena such as landslides occur more frequently in the world. We reported recently about a number of set phenomena of this kind in China, but what you can see in Sweden is really shocking. Depression, called point Fabian and is located near the town Gallivare in northern Sweden. Recent aerial photographs show us some details about this incredible formations. ![]() This sinkhole is almost regular shape with a side of about 150 meters. The locals obviously are not thrilled the company, especially that of the hole sometimes hear loud noises probably caused by wind. ![]() Witnesses say that the sounds sometimes lasts for 45 minutes and resemble the sound of planes taking off. Some of the sound emitted from the Carpathian sounds like a volcano.

Sinkhole nearly swallows car in Burlington Mall parking lot Mall to reopen Friday UPDATED 6:30 AM EST Feb 21, 2014 BURLINGTON, Mass. —A water main break reported at the Burlington Mall created a sinkhole Thursday afternoon and caused the front end of a car to become stuck. Officials representing the Burlington Mall said the water main break was reported in the parking lot by Sears, and as a result, a large sinkhole formed and the front end of the vehicle became stuck and lifted the back of it into the air. Jeanette Gordon said she’s just taking it all in stride. It was her vehicle that was stuck in the sinkhole. “It’s odd, isn’t it?” she said. “I didn’t believe it.” Gordon said her daughter brought the car to the mall, which is where she works as a sales associate. “She just came out of work and saw the car, and she calls me and says, ‘Mom. You’re going to have to get a ride home from the train station,’” Gordon said. Officials said the mall closed early while emergency crews worked to remove the car from the sinkhole and then make repairs to the broken water main. Officials said the Burlington Mall should be open its normal hours on Friday. http://www.wcvb.com/news/sinkhole-forms-in-burlington-mall-parking-lot/24585826 Eight pictures (here are three) ![]() ![]() ![]() http://www.wcvb.com/news/sinkhole-prompts-mall-closure/24586214 Sinkhole Opens Up Under Car In Burlington Mall Parking Lot ![]() The mall was closed at 5 p.m. due to water problems caused by the break in the main. The owner of the car was working inside the mall when the announcement was made. “So we’re all like closing the register, cleaning out the store, and then we just like left and went to the parking lot,” says Kelly Gordon. “And that’s when I saw my car.” Kelly had joked about the situation until she went out to the parking lot. “I was really, really mad and then I started crying when I got on the phone with my dad,” she says. Crews were working to fix the water main break late Thursday night and a spokesperson says the mall will be open at the normal time on Friday. http://boston.cbslocal.com/2014/02/20/sinkhole-opens-up-under-car-in-burlington-mall-parking-lot/ Burlington Mall reopens after sinkhole incident The Burlington Mall reopened this morning, after a water main break in the mall’s parking lot forced the building to close Thursday afternoon, a mall spokeswoman said. The break outside the Sears store caused a Toyota Camry to dip into a sinkhole. The car was towed and no injuries were reported, said spokeswoman Linnea Kelliher. Burlington public works employees and police will investigate the cause of the break. It is still unclear if it was related to the weather, said Kelliher. http://www.boston.com/2014/02/21/burlington-mall-reopens-after-sinkhole-incident/JOxETo9lpdzDifCn4eLHmN/story.html |

I can tell you now, I won't be able to keep up. I got behind by three the other day. It takes so much time and effort. Not that I don't want to because I do want to. I'm going to bypass the 3 I missed and move on to the ones I collected today. ======================== Sinkhole opens on Penn State campus February 24, 2014 ![]() A large sink hole was discovered Sunday by the loading dock of the Penn State electrical engineering building. The Penn State office of the physical plant is investigating and working on the problem, February 24, 2014. UNIVERSITY PARK — A large sinkhole opened Sunday on the Penn State campus, closing a portion of a parking lot Monday. Penn State’s Office of Physical Plant closed a portion of the Brown A lot and the EE East loading dock in the area of Pollock and Burrowes roads while repairs are made, according to a university news release. Work crews were digging out the sinkhole Monday, and the university reported that the lot should be fixed in one week. Those with Brown A permits will be allowed to park in the Red A lots near the IST Building until Friday, the university stated. Sinkholes are nothing new to University Park or State College. In October 2012, a major sinkhole forced the State College Area School District to close a portion of the Memorial Field bleachers, the site of State High home football games. The field reopened before the 2013 fall football season but only after about $3 million in repairs, which included new west-side bleachers, a temporary bleacher on the eastern side of the field, a draining system that runs water to the sinkhole and new turf. A sinkhole also opened in October 2012 off Park Avenue on the Penn State campus. The sinkhole caused a storm drain pipe to break.

Sinkhole Surprises St. Louis City Street Crew February 24, 2014 ![]() Work crews prepare to fill a sinkhole with rocks in the 8400 block of Minnesota in south St. Louis, after another truck had been stuck in the hole. ST. LOUIS–(KMOX)–A sudden, gaping hole in a paved alley swallowed the back wheels of a city street department truck, with chunks of asphalt falling ten-feet below while the truck teetered over a cavernous void. No one was hurt and the truck was pulled free. But the hole in the 8400 block of Minnesota required a dump truck full of rocks to fill, and neighbors complained the area is honeycombed with caves that have opened up before. ![]() Crews dump rocks hoping to satisfy the appetite of a sink hole. “It’s all under this whole area down here, caves,” said Charles Erxleven, “It’s a costly operation to be living here when something like this has happened. This house has had them. They had to go 22 feet down.” Work crews patched up the hole and were watching it to determine whether the void was now stable. http://stlouis.cbslocal.com/2014/02/24/sinkhole-surprises-st-louis-city-street-crew/ |

West Texas sinkholes cause for concern, and wonder February 24, 2014 WINK, Texas (AP) — The Wink Sinks of Winkler County are barely visible from the highway, and you are not allowed to visit them. But judging from piles of beer cans and the gaps cut into the fences blocking them off, people do anyway. Wink Sink No. 1, as it's called, appeared in 1980. The bigger and more active Wink Sink No. 2 opened in 2002. And they keep expanding. County officials keep an eye out, preparing should the sinkholes envelop nearby roadways or oil production equipment. In the meantime, geologists keep studying the Wink Sinks, even though funds for a comprehensive effort dried up in 2010, and signs posted around the oil leases that surround the sinks warn of "Unstable Ground." At Wink Sink No. 2, fissures split the earth in waves extending hundreds of feet from the hole. It's just shy of a mile east of the first one. Some of the fissures are big enough to swallow a person. "This looks like something from the moon or Jules Verne or something," Winkler County Sheriff George Keely said during a recent visit to Sink No. 2. He said not much scares him, "but I do not like being out here." The sinks are breathtaking in their size and jarring, with broken pipeline jutting out over each of them and cracked fallen rock that looks like a quarry in the middle of a dusty mesquite field. Common news-making sinkholes — like the 40-foot-wide, 20-foot pit in Bowling Green, Ky. that swallowed eight unique Corvettes earlier this month or the Florida sinkhole that enveloped a man's house last year — are created through what is known as karst processes, which is when water dissolves bedrock over time until a sudden collapse. Bowling Green, for example, sits atop a limestone shelf and cave system. But the Wink Sinks are different, said Robert Trentham, a geologist at the University of Texas of the Permian Basin who has studied them since Wink Sink No. 2 emerged. The sinks happened where layers of salt water piled atop each other not far below the surface. Groundwater for as long as 70 million years dissolved those salts, and water-supply wells pumping out of the Capitan Reef aquifer probably sped along that process, until a void grew so large underneath the earth that the surface caved in, Trentham said. "There's a component of nature and a component of man in there," Trentham told the Odessa American (http://bit.ly/1hiKKqm ). "It's a really complex story." The karst-formed sinks stay more or less static once they form. Not the Wink Sinks. Odessa American archives chronicled Juan Garcia of Kermit, then a 26-year-old roustabout, as among the first to stare at the ground giving way at one of the Permian's oldest and most prolific oilfields. Garcia said he saw the ground crumbling and water splashing up. "It was kind of exciting to see everything go down a hole," Garcia recalled years later. First the hole opened at about 20 feet wide and grew to more than 400 feet across today. It is an estimated 80 feet deep, partially filled with fresh water. It fell to Robert Baumgardner, a 29-year-old research associate for the state Bureau of Economic Geology, to investigate the hole. He also named it, rejecting "Kermit Crater" because craters are technically caused by impact and the sink hole was technically closer to Wink. Baumgardner published a paper a year later attributing the sink to dissolution of underground salt. The second sinkhole that opened in May 2002 is less than a mile away, toward Wink. Its original width was 450 feet across. Operators plugged the wells in the surrounding square mile. A sheriff's photo shows the first fence placed a few dozen feet from the ledge. But now Sink No. 2 has blossomed to an oval shape with widths across that vary from about 700 feet to more than 900. And today chunks of the ledge lean in, with fissures extending hundreds of meters. The sink swallowed much of the fence from the sheriff's photo, its barbed wire dangling toward the water. "It's very impressive. I guess that's how I would say it," County Judge Betty Leck said. "When you talk about sinkholes, I haven't seen any that compete in size to ours. And we're lucky it's in a rural area." With the second sink, concern built in the community and on the oilfield lease that maybe some more might pop up and threaten the nearby Shell oil tanks or the highway or worse. The Texas Department of Transportation began to monitor the highway and the county came up with a sinkhole disaster response in its Emergency Management Plan. The Bureau of Economic Geology and UTPB teamed up in 2008 for a study funded by about $200,000 that came in part from oil company donations. A lot of that money went to aerial analysis equipment, Trentham said. But the team also assessed public infrastructure and shared with local planners. And they collected data from oil and gas companies about petroleum infrastructure. Trentham said the biggest takeaway was a "baseline" that offered a sense of what caused the sinks and sags and how they developed. Other ideas about the cause of the sinkholes still circulate in town: a sudden tectonic shift, for example. But the researchers who continue to study the formation say they remain confident in Baumgardner's finding. They are less certain whether oilfield activity played a role but consider it probable: Wells in the Hendrick Field, operating since 1926, would provide a mechanism to dissolve the salt and weaken the earth, according to a 2012 paper by Jeffrey Paine, the principal investigator for the Bureau of Economic Geology. Wink Sink No. 1 surrounds an oil well drilled in 1928 and abandoned in 1964. Wink Sink No. 2 surrounds a water-supply well drilled in 1960 and estimated to have yielded 800 million barrels. "I don't know how you could do that unless you could go down with some sort of sensor and find the cavity that initiated the collapse," said Baumgardner, who has not visited in a few decades. And now scientists such as Paine continue to probe just how safe or how dangerous the sinkholes are. This includes aerial surveys and gravitational diagramming, which, as it happens, show the indentions in the field that might be "sinkhole prone." "There's always a chance that something could happen there," Paine said. "It's one of the more interesting places in the state." http://www.chron.com/news/texas/article/West-Texas-sinkholes-cause-for-concern-and-wonder-5262992.php?cmpid=htx |
