Earthquake tremors near Armidale, close to Dorrigo, labelled a 'non-event'

The 2.5 magnitude tremors hit 50 kilometres east of the town at 9:58pm.

Geoscience Australia seismologist Spiro Spiliopolous said they did not receive felt reports in Armidale.

“There is a swarm going on south of Armidale,” he said.

“We don’t expect any damage from an earthquake of that size, it’s too small for that.”

The earthquake began closer to Dorrigo.

Armidale Dumaresq State Emergency Services controller Josh Osborne said he did not receive any calls.

“It was a quiet event, quiet earthquake,” he said.

“I missed the earthquake myself, I was working.

“I remember the 2012 earthquake, a couple of window panes rattled and it felt like a truck went by my house.

“Also a non-event.”

Earthquakes are not common in the region, the last one registered as a 4.2 magnitude in 2012.
