EARLIER: A BIGGER earthquake could hit the Coffs Coast after 15 shook Dorrigo and Bellingen in the past few days.

Geoscience Australia seismologist Hugh Glanville said earthquakes in this region were rare.

"It's pretty unusual," Mr Glanville said.

"We haven't had a swarm (of earthquakes) in that area for a long time."

But after the swarm of quakes ranging from a 2-3 magnitude shook up the local area, he could not rule out a larger one.

"There is always the chance of a bigger earthquake," he said.

"We never rule out the chance of a bigger earthquake."

Three earthquakes were detected in the area this morning, the largest a 3.3 magnitude at Bellingen.

Mr Glanville said a 3-plus magnitude earthquake could be felt up to 50km away and lasting for up to 10 seconds.

"People describe it like a truck passing through your house," he said.

While he said a magnitude 2 earthquake caused a short shake and may cause a "bang".

Mr Glanville said the earthquakes around Dorrigo and Bellingen at this stage had not caused any damage but ones over a magnitude 4 were likely to cause damage.

He said earthquakes were not unusual in NSW with between 100-200 reported each year.
