Two cars rest at the bottom of a sinkhole that opened up on Woodbridge Street near Laurel Canyon Boulevard in Studio City on Friday, Feb. 17, 2017.
Two vehicles fell into a 20-foot sinkhole in Studio City today and firefighters had to rescue one woman who escaped her car but was found standing on her overturned vehicle.

Firefighters arrived shortly after 8:15 p.m. at 4245 N. Laurel Canyon Blvd., two blocks south of Moorpark Street, to find one car upside-down in a large dark sinkhole full of rushing water, said Erik Scott of the Los Angeles Fire Department.

The single occupant was standing on the car, approximately 10 feet below street level, Scott said.

"Firefighters jumped into action and rapidly lowered a (20-foot) extension ladder down to the (48-year-old woman) allowing her to climb out, and transported her to a local hospital in fair condition," Scott said.

Huge sinkhole shuts down street in northeast Washington State

A massive sinkhole shut down a section of North 8th Street in Lynden Thursday.

Residents noticed a small hole forming on North 8th Street about 8:00 p.m. Wednesday, and by the morning, it was halfway through the street, according to Lynden Mayor Scott Korthuis.

North 8th Street is closed between Pine and Ivy Streets.

A culvert under the street failed, and crews had to remove the sidewalk and a portion of the street, according to Korthuis. "The pipe has probably been in the ground for 40 years. That pipe started to rust and fail. The water got under the pipe and started to wash out the dirt, and that started the sinkhole," said Korthuis.

The sinkhole is about 30 feet wide and ten feet deep. The water channel is about 10 feet wide and has washed out about 90 feet of land.

A vast sinkhole estimated to be 15 meters wide and 20 meters deep has caused a major road collapse in the city of Vladivostok in Russia's Far East.

The incident took place during excavation works while a building was being constructed, the local administration said on its website.

People at the nearby Seaside Regional Institute of Education Development were evacuated following the collapse. The collapsed part of the road was cordoned off by police.


"It all happened during a lunch break... We heard a loud noise and looked in the window - a concrete wall collapsed in the abyss [on the road]. Then a big sinkhole began to form on the road," an eyewitness told TASS.

Sink holes have been appearing over the past month in the Cho Don District of the northern mountain province of Bac Kan, generating anxiety among local residents.
Sink holes have been appearing over the past month in the Cho Don District of the northern mountain province of Bac Kan, generating anxiety among local residents.

According to a preliminary survey by the district's People's Committee, more than 20 holes were found in the district, with each measuring 2-5 metres in width and 2-3 metres in depth.

Ban Tan Hamlet in Bang Lung Town has suffered the most. It has recorded more than 10 land subsidence spots. Some of the sinkholes appeared in springs, diverting all their water under ground. Over the past 10 days, some springs in the district have dried up, leading to water shortage for daily activities as well as irrigation.

Cracks have also appeared, with some measuring hundreds of metres in length.


Hoang Van Trieu, a farmer in Ban Tan Hamlet, said he was very anxious because big holes appeared in his fishing ponds while cracks were recorded in his garden, fields and the foundation of his house.

Three tow trucks were used to keep an unoccupied Oldsmobile Alero from falling into a sinkhole in the Taco Bell parking lot near the intersection of U.S. 421 West and Winkler Mill Road in Wilkesboro about 8 a.m. Monday.

Asphalt had collapsed beneath both tires on the driver's side of the Oldsmobile and it was at risk of falling into the hole by 7 a.m. Monday.

Two conventional tow trucks, one at the front and the other at the rear of the Oldsmobile, were used to left up the car while a rollback tow truck was used to pull it in the direction of the passenger's side and onto the flatbed of the rollback.

A spokesman for Champion Towing in Wilkesboro, which had the rollback and one of the other tow trucks on the scene, said the Oldsmobile was removed from the hole without a scratch. The other tow truck was from Southeastern Cars & Parts in Ronda.

People on the scene Monday morning said the hole could easily be jumped across when it first appeared Sunday. It was at least 20 feet deep and the opening in the asphalt was at least 10 feet across by 8 a.m. Monday, but it was even wider immediately beneath the asphalt.

A large sinkhole appeared Sunday on East 27th Street in East Oakland.
Workers from several agencies on Monday were continuing to repair a large sinkhole that appeared Sunday morning in East Oakland, damaging utility lines and partially swallowing a parked car, officials said.

The hole, about 25 feet wide, 25 feet long and 20 feet deep, opened about 9:21 a.m. in the 2600 block of East 27th Street in the lower Dimond district.

No one was in a parked 1991 BMW that was left partly submerged. It was later towed out.

On Monday, there were workers from the City of Oakland, PG&E and a private contractor at the scene. It was not known when the hole would be refilled and all repairs completed but crews were working around the clock to expedite the repairs, officials said..

Some underground sewer and storm drain lines were damaged as well as the roadway, officials said, but the extent of the damage or how many users were affected was not immediately available.

Gaping sinkhole opens near Australian PM's home

A sinkhole has opened up near Malcolm Turnbull's Sydney harbourside mansion rupturing a gas pipe.

Fire and Rescue NSW were called to Wentworth Street, Point Piper, this morning after the footpath collapsed following the freak weather which had smashed Sydney the day before.

"There was a leak from a gas pipe," a Fire and Rescue NSW spokesman told The Australian. "It was due to the weather, now whether that is a cracked pipe or not I'm not sure at this stage.

"We were notified about it at 7.12am — we responded with a pumper, a station officer and three fire fighters. "Every pumper has air-monitoring equipment on board which can check for explosive limits and deprivation of oxygen and hydrogen sulphide.

Earth 'overdue' for magnetic pole reversal

The Earth's magnetic field, magnetic poles and geographic poles.
Earth's magnetic field may be about to reverse, which could have devastating consequences for humanity.

Scientists think that Earth is long "overdue" for a full magnetic reversal and have determined that the magnetic field's strength is already declining by 5 percent each century. This suggests that a fully reversal is highly probable within the next 2,000 years

Earth's magnetic field surrounds the planet and deflects charged particles from the sun away, protecting life from harmful radiation. There have been at least several hundred global magnetic reversals throughout Earth's history, during which the north and south magnetic poles swap. The most recent of these occurred 41,000 years ago.

During the reversal, the planet's magnetic field will weaken, allowing heightened levels of radiation on and above the Earth's surface.

The radiation spike would cause enormous problems for satellites, aviation, and the power grid. Such a reversal would be comparable to major geomagnetic storms from the sun.

The sun last produced such a storm that struck Earth during the summer of 1859, creating the largest geomagnetic storm on record. The storm was so powerful that it caused telegraph machines around the world to spark, shocking operators and setting papers ablaze. The event released the same amount of energy as 10 billion atomic bombs.

Researchers estimate that a similar event today would cause $600 billion to $2.6 trillion in damages to the U.S. alone. National Geographic found that a similar event today would destroy much of the internet, take down all satellite communications, and almost certainly knock out most of the global electrical grid. The Earth would only get about 20 hours of warning. Other estimates place the damage at roughly $40 billion a day.

A similar solar event occurred in 2012, but missed Earth.

School bus narrowly escapes large sinkhole in Toronto, Canada

The ground nearly swallowed part of a school bus in the city's Harwood neighbourhood Monday after a massive sinkhole opened up in a local road.

The bus was travelling south on Symes Road, just past Hillborn Avenue, when the pavement beneath it suddenly collapsed.

The back of the bus slammed down into the opening sinkhole, but the vehicle luckily had enough momentum to keep from getting lodged. While it escaped the hole, reports from the scene indicate that the rear suspension was shattered and the drive axle was partially dislodged.

The bus eventually came to a stop a few metres away from the sinkhole, where rushing water could be seen gushing through the two-metre-deep opening. Toronto Water is at the scene to assess the situation and police have closed off a section of the road to keep drivers away.

There were no kids onboard at the time. No one was injured.
