SAN FRANCISCO (AP) — Authorities are trying to figure out what caused a massive sinkhole that started swallowing a big rig on a San Francisco street Friday.
The driver, Alejandro Curiel, told KRON (http://bit.ly/2pO6MNJ ) that he had stopped the truck against the curb when it started slowly sinking on the right side.
He scrambled to climb out of the driver side because a tree was blocking the passenger side. He escaped unharmed.
San Francisco Public Utilities Commission spokeswoman Betsy Rhodes said they have not identified an obvious cause of the sinkhole that measured 10 feet (3 meters) by 20 feet (6 meters) and about 8 feet (2.5 meters) deep.
She said previously that a sewer main may be to blame.
Rhodes said the area around the sinkhole in the city's South of Market neighborhood was stabilized and not in danger of sinking.
The driver, Curiel, told the TV station that he "can't believe it happened to me."
Someone started a Twitter account in the name of the sinkhole and said it was just chilling. It also wished everyone a happy #Sinkholedemayo in honor of Cinco de Mayo.
