Earthquake in Gauteng today

We here in benoni also experienced it for  a solid odd minute . I was putting my 2 yr old down to nap, dont usually sit with him but I did today, walls started shaking, mirror and desk lamp shook off his shelf. and  skylight started cracking. When I realised it wasn't going to stop I grabbed him to run down our 3 flights of stairs, the house was shaking so badly that we couldnt see the balustrade or the hand rail. Very scary. Once ouside you could see the houses around us shake.
