Massive tremor in Jhb?

Thousand of kilometers of tunnels beneath Johburg all along the great reef, the ground below is basically a honeycomb of old mines. We had tremors on a daily basis in the late 90's in Boksburg. I'm surprised the big quakes don't happen more often. Literally all those tunnels just collapsing and settling. Last I heard they were pumping the sediment back down into them.

Topstar was a thing.
 
That the drive-in?

Back then we had the Fun Factory in Boksburg and Randburg Waterfront actually had a lake with a bungee jumping platform in the middle of it.
Topstar was on top of a mine dump. Pretty much all of those mine dumps are gone now.

People love to say this, although its a vanishingly small amount of tunnels compared to the rest of the crust, insignificant I'm sure
 
Scary. Was sitting on the edge watching ornaments fall off the shelf.
Same. Some of my stuff also rattled off the windowsill.
Got the skik of my life.

Also left a light tremor this morning between 11 and 12 I think.
