As per google
A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone.

Sometimes it's to do with the soil being too dry and collapsing on itself.
In this case, it is near some new tunnels that are being created for Highway 16, and they are investigating whether that caused some instabity/weakening of the area.
Interesting article here about the causes of sinkholes.

Really either cause could apply here. Jerusalem has a very high proportion of limestone in the soil, and we've had a couple of very wet winters lately, so there would have been a lot of groundwater.
And as mentioned above, there has been a lot of tunneling in the area, leading to general instability in the bedrock.
The third option is that it was a very small, localised earthquake!

They're not that unusual in this area.
There was one just a week ago at one of the southern entrances to Jerusalem where they're excavating a new tunnel. Caused one heck of a traffic jam 
And there was one in the center of town last summer.
And of course the Dead Sea area is full of them.
And yes, Parshat Korach did indeed come to mind especially because political events can also be construed as providing somewhat of an echo to the parsha....

Near the Dead Sea, sinkholes occur frequently since the level of the sea has been receding. Freshwater seeps into the ground and dissolves the salt that is under the surface in the dried up seabed, and creates cavities. Then so somebody steps on the thin crust of earth that is left and whoosh! It collapses.

My first thought while watching it was 'reminds me of korach v'adasoi'. I didn't even realize it was parshas korach!

I was at Shaarei Tzedek today for an appointment! But in the morning and before the sinkhole broke open. There were no injuries or anything, right?
Guess finding a parking spot round there has just gotten even harder... dang, I still have a bunch more appointments
