A 4.6 magnitude earthquake rocked parts of Australia's second largest city, Melbourne, today, but there were no reports of damage or injuries, according to Reuters. Geoscience Australia said the tremor's epicentre was about 90 km (56 miles) southeast of Melbourne. "It was certainly a moderate earthquake that was likely to be felt across a wide area but is unlikely to have caused any damage, except possibly some minor damage near the epicentre," Geoscience seismologist Phil Cummins told local media. Victorian State Emergency Service (SES) said there had been no reports of damage or injuries.
