The epicentre of the tremor was said to be beneath UJ’s Auckland Park campus by the Council for Geoscience but Dr van Niekerk suspects that a more accurate analysis would find the tremor started at a nearby mine shaft.
“It is very difficult to come up with an epicentre because it takes a lot of reading data, but there are no old mine shafts underneath the university itself so it is highly unlikely. UJ may just have been used as it is a recognisable landmark. Now, if you go just over Brixton hill to the southern side of Brixton Ridge, there are many abandoned open mines. If these mine shafts collapse, they will obviously cause the place to shake.”
