According to Times Online:

Hundreds of schoolchildren and miners were evacuated when the biggest earthquake in 50 years hit Australia’s Goldfields earlier today, causing damage to buildings in two towns. So far, only two people have been reported as being treated for minor injuries.

The shallow, 5.0 magnitude quake struck about 8.20am local time (23.20GMT), 10km (six miles) north-east of the gold mining city of Kalgoorlie and the neighbouring town of Boulder in Western Australia.

The prediction is more earthquakes will come to pass at more locations, try to prepare in advance if possible in terms of food & water supply.

Somewhere else in the world are also having earthquakes.
