'More aftershocks': Tremors expected for days after 5.6-magnitude earthquake rattles Queensland

Aftershocks may be felt for days to come after a 5.6-magnitude earthquake rocked Queensland yesterday.

The strongest on-shore earthquake in 50 years rattled Queenslanders as they woke up, with tremors felt from Hervey Bay all the way to parts of northern NSW.

The epicentre struck around 200km north of Brisbane about 9.50am at a depth of 10km, with thousands of residents reporting they felt the quake.

More tremors could be on the way and Queenslanders have been warned to brace for some mild aftershocks, according to Geoscience Australia.

"It was decent wobble. And yes, we're likely to see aftershocks," seismologist Michelle Salmon told Today.

"In fact, there was actually [was one] last night. It was small enough that it was quite difficult for us to locate, so it didn't actually get published, but someone did feel it.

"So we can expect some aftershocks."

The initial quake was felt by around 20,000 people and left 13,000 properties without power.

Locals in the rural Queensland town of Kilkivan, where the epicentre is located, couldn't quite believe the ferocity of the earthquake.

"I'm sitting outside having breakfast and there was just this big... it felt like an explosion, like a gas bottle had gone off," one witness told Today.

"Tiny town. Nothing normally happens out here."

The quake was felt as far away as Brisbane, with witness reports saying they felt the shake as far afield as Bundaberg and the Gold Coast.

There have been no reported injuries or major damage.

"I don't think anybody expected to wake up to that today in Queensland," Premier David Crisafulli said yesterday.

"There's been some amazing stories that have come through and we obviously are waiting to see… damage and we hope everyone is OK."
