Residents on Tasmania's northern coast have woken to tremors after a 3.4-magnitude earthquake struck 10km from the shore.The earthquake, about 10 to 12 kilometres from Wynyard, hit at 7.21am (AEDT) on Sunday, sending short and sharp tremors to nearby Burnie and as far away as Launceston, said Geoscience Australia seismologist Jonathan Bathgate.
Mr Bathgate said the agency received around 100 calls from residents who felt the tremors.
"It's been fairly widely-felt across that section of Tasmania," he said.
"They generally hear a loud noise and feel a sharp, sudden jolt.
"The phones have been just ringing constantly.
"I think it woke a few people up."
