Check Out the Massive Sinkhole Tearing Apart a Street in San Fran

A new sinkhole has opened up; this time in San Francisco.

A massive 30-by-20 foot sinkhole tore apart a street in the Bay Area of San Francisco on Wednesday, according to a CBS local San Francisco affiliate.

The sinkhole, caused by heavy overnight rain, sits at the intersection of Lake Street and Sixth Avenue.

Jean Walsh, a spokesperson for the San Francisco Public Utilities Commission, told CBS that sand had eroded around an underground water main pipe at the intersection. As a result, the pipe collapsed, causing rocks and sand to erode.

This sinkhole has an explanation as to why/ how it formed unlike the other ones in recent times: Siberia, Florida.....
This one is due to the torrential rains California is getting right now where sand/ sediment under the road was washed away and the hole opened. Still though, it's a bit unnerving.

What says ATS?

The war machines are getting ready to emerge from the ground.

a reply to: strongfpNice blurp about War of The Worlds. However, I am surprised that it does not happen more often out there in San Francisco. The whole area sits on a marsh of sorts.

Couldn't help but laugh at Nature's pun...

The sinkhole, caused by heavy overnight rain, sits at the intersection of Lake Street and Sixth Avenue.

Name a street Lake Street in a geologically unstable area... nature opens up a hole and fills it with rain.

Here's the picture,




The Florida sinkholes causes are known, the bedrock is *sandstone. It's more likely for sinkholes there to appear in areas where the *sandstone has degraded badly forming caverns, and when the water table goes down that's when a sinkhole can occur. When the caverns are full of water they help support the weaker subsoil above.

* Sorry I meant Limestone.
Just to add, look at all the old patches on that road. Aside from the pipeline or whatever that is, They are all in the area of collapse, somebody shudda knew something!

Looks like they had that area open before for a main repair or something, by the looks of the patch work.
Maybe the sandy soil washed onto the storm line.
Id be the first one to drive into it while changing the radio.
