Mining in the spotlight over quake
Wednesday 6 August 2014 – 6:44pm
JOHANNESBURG – Seismologists say Tuesday’s earthquake was the result of natural shifts in the earth’s crust.
But, mining activity may have been the trigger as untreated acid water is a catalyst for earth tremors in South Africa’s mining regions.
For seismologists to be able to state conclusively these earthquakes are caused by mining, they need to prove that earthquakes didn’t take place in the area before miners started digging. That historical data doesn’t exist.
Nonetheless, the Treasury has allocated R225-million over the next two years to clear water out of Gauteng’s gold mines.
