You probably don't think about what's under the street much, but you might start to now. A sinkhole opened up in the middle of a Philadelphia street, and it was apparently full of this green ... stuff. What does this mean? Are secret tunnels below the streets pumping radioactive goo across the country for some nefarious purpose? No. As the Redditor who took this photo learned, this is actually a fluorescent dye. Cities add it to water in sinkholes to see where they go, and hopefully fix the problem that causes it. Still, nearby pizza restaurants should be on the lookout for a pack of giant talking turtles. Just in case. [Source]

Four families have not been able to return to their homes due to a giant sink hole caused by a water main break in South Philadelphia. It's at the middle of the intersection at 21st and Bainbridge. Crews say the sink hole is 15-feet deep.

"It's enormous," said flooding victim Marisa Block. "I heard sink hole and I was thinking something like three or four feet, nothing that big. It's the entire intersection!"

The 96-year-old, 48-inch transmission main broke at 9 p.m Sunday, according to a spokeswoman for the Philadelphia Water Department.

Crews worked through the night, where water flowed up to three feet high in some spots, as you can see in this NBC10 viewer photo.

On Monday, there was a gas leak at the same location, but authorities say it was quickly fixed.

A sinkhole swallowed up the front end of a car on a street in Philadelphia's Hunting Park section early Tuesday morning.

The nose of the Pontiac Bonneville was sinking down below the street - its rear raised in the air. That was the sight neighbors were met with early this morning on the 3600 block of Marvine Street in Hunting Park.

Car owner Fran Leftenant woke up to an officer knocking on her door.

"I thought I had two missing tires, but it wasn't the case. My car was sinking," said Leftenant. "Right now I'm just sick."

She and other residents watched as the hole got deeper, and the lean on the car greater. A tow truck was called.

The sinkhole formed at about 10 feet. It's now an estimated to be about 50 feet wide and 50 feet deep.

A big sinkhole in Christian County is getting even bigger.

It's in a field in the bent-water subdivision on the north side of Nixa.

The sinkhole formed at about 10 feet. It's now an estimated to be about 50 feet wide and 50 feet deep.

Since it's on private property, it's up to the developer to decide what to do about it.

The person who lives close to the sinkhole is bringing someone in to determine its potential impact.

Man swept along 15 metres on to railway line by torrent outside his home in Walsden following day of heavy rainfall

Roads and railway lines were submerged in water after torrential rain and flash flooding hit one small town for the second summer in a row.

Parts of the market town of Todmorden, West Yorkshire, were left under 45cm (18in) of water. Emergency services worked late into Monday night to clear the water and deal with hazards such as partially collapsed roads.

One resident in nearby Walsden was swept along about 15 metres by the torrent. He was carried downhill and ended up on the railway tracks at the end of his street.

Clearing out his flood-damaged home, the man said he was too shaken to talk about the incident.

One of his neighbours said: "The water was bubbling up and he was trying to redirect it. He went through the gate, was taken down the road and under the gate, on to the railway lines.

"He thought he was a goner. It's a fair distance. And with the torrent that was coming through, he's lucky to be alive today. Very, very lucky."

Dramatic mobile phone footage taken from inside office building shows the moment a tornado hit near Milan, injuring 12 people and filling the air with flying debris.

The twister swept through Grezzago, an industrial area of Milan in Italy on Monday, overturning vehicles, uprooting telegraph poles and damaging buildings.

Footage uploaded onto social media site www.youreporter.it shows the tornado swirling around the outside of an office building, hurling debris in the air.

No causalities were reported but at least 12 people were left injured by the tornado .

A cement truck proved to be too much for a street section on Xian's outskirts on Saturday, causing a seven-metre-deep sinkhole and raising questions over construction safety in China.

In the early morning, a cement truck was swallowed by a sinkhole as it was on its way to its daytime deployment in northern China's Shaanxi province. No one was injured, and the driver was able to escape the vehicle. It took urban authorities until 10pm to remove the truck from the site.

Coastguards have issued a warning to holidaymakers after a cliff fall at a "vulnerable" section of coast in Dorset.

The landslip took place at West Bay, near the area where holidaymaker Charlotte Blackman, 22, died when a cliff collapsed and crushed her last summer.

Heavy rainfall at the end of last week is thought to have made the land unstable and crumbly, the Maritime and Coastguard Agency (MCA) said.

No-one was injured in the landslip, which happened near Freshwater Beach Holiday Park on Friday and has left the cliff with an overhang.

A driver and his passengers had a lucky escape after the car he was driving was almost buried under a landslide in China.

Video of a car almost being washed away by floods and a landslide in northwest China has been released.

The footage shows the driver trying to get away from the deluge, but changing his mind when he realises what is happening.

All the car's occupants escaped unhurt.

Almost a million people have been affected by flooding in the region since the start of July.

Traverse City, Michigan - Already ravaged by toxic algae, invasive mussels and industrial pollution, the Great Lakes now confront another potential threat that few had even imagined until recently: untold millions of plastic litter bits, some visible only through a microscope.

Scientists who have studied gigantic masses of floating plastic in the world's oceans are now reporting similar discoveries in the lakes that make up nearly one-fifth of the world's fresh water. They retrieved the particles from Lakes Superior, Huron and Erie last year. This summer, they're widening the search to Lakes Michigan and Ontario, skimming the surface with finely meshed netting dragged behind sailing vessels.

"If you're out boating in the Great Lakes, you're not going to see large islands of plastic," said Sherri Mason, a chemist with State University of New York at Fredonia and one of the project leaders. "But all these bits of plastic are out there."

Experts say it's unclear how long "microplastic" pollution has been in the lakes or how it is affecting the environment. Studies are under way to determine whether fish are eating the particles.

The newly identified hazard is the latest of many for a Great Lakes fish population that has been hammered by natural enemies like the parasitic sea lamprey, which nearly wiped out lake trout, and man-made contamination. Through it all, the fishing industry remains a pillar of the region's tourist economy. Until the research is completed, it won't be clear whether the pollution will affect fishing guidelines, the use of certain plastics or cities that discharge treated wastewater into the lakes.
