AN EARTHQUAKE about 10 kilometres off Tasmania's north coast rattled dishes at Wynyard but left no reports of damage.
The magnitude 3.4 earthquake struck at 7.21am yesterday - about 10 kilometres from Wynyard in Bass Strait - and lasted one or two seconds.
A 2.5-magnitude aftershock followed about 10.30am.
Seismologist Jonathan Bathgate said although earthquakes of this magnitude did not occur every day, there was a history of them in the region.
"There was a 3.5 and 3.7 quake in 2007, a 3.6 in 2006, dozens of magnitude-2s and, early last century, a magnitude- 5 off Strahan," he said.
Mr Bathgate said that more than 150 people reported the event through the Geoscience Australia website, with "no shortage of phone calls" too.
"It could certainly be felt, but there were no reports of damage and neither would you expect there to be at this magnitude, that far offshore," he said.
