The SA Weather Observer did issue this precautionary:
“It is not known whether this tremor is a pre-shock to a major earthquake. Earthquakes fall into 3 categories. Some have fore-shocks, some show subtle signs, and others have aftershocks.
Earthquakes are still not predictable. Some have no warning at all and never show any signs of happening. The third group follow no pattern at all, they go seemingly randomly, and they can not even be estimated. It is very hard to tell which fault will be in which group, and this is why prediction is still impossible. The designation of an earthquake as fore-shock, main-shock or after-shock is therefor only possible after the main event.”
