Australia’s second-largest earthquake in two decades struck north-western WA on Sunday night.

The 5.9 magnitude earthquake struck offshore, around 100 kilometres from Coral Bay, at a depth of 10 kilometres at around 10:26 pm local time.

The Joint Tsunami Warning Centre advised that there was no tsunami threat from the submarine ‘quake, which was felt as far south as Perth — around 1,000 kilometres from the epicentre.

Coral Bay residents reported experiencing violent tremors, but no significant damage has yet been reported.

The main event was soon followed by a 3.7-magnitude aftershock off the coast of Carnarvon, with Geoscience Australia warning that tremors with a magnitude of around 3 would be plausible following an event of this scale.
