Earthquakes
The quake, one of the largest to hit the state in many years, was recorded 60 kilometres west of Bowen just after 3.30pm (AEST) Saturday.
The rumblings were felt in several towns throughout the region, but police say there are no reports of damage or injuries.
There have been several aftershocks, with one registering a magnitude 4.

Damage seen from the devastating earthquake in February, which followed a quake last September
New Zealand's second largest city remains devastated following a 6.3-magnitude earthquake in February which claimed 181 lives, and followed a stronger, but less destructive 7.1 quake last September.
The latest tremor hit at 5:49pm (local time) and was centred 16 kilometres west of the city at a depth of nine kilometres, the US Geological Survey said.
The tremor struck about 3.30pm local time (0530 GMT) about 124 kilometres southeast of Townsville at a depth of 10 kilometres, according to the United States Geological Survey.
A low rumbling was felt at Magnetic Island, a 20-minute ferry ride from the mainland and part of the Great Barrier Reef, according to a hotelier at the All Seasons resort, where it briefly interrupted a wedding on the beach.
"Some of the guests felt a bit of a shake, nothing much. It wasn't major, no-one fell over and nothing was damaged," she said.
"It was just like a shudder, my office backs onto the laundry and I said 'Oh, that was a big spin cycle.' It hasn't stopped the world up here.
Here's how the U.S.G.S. breaks down the science of the earthquakes:
4:47:25 a.m. - a 3.2-magnitude earthquake hit 14 miles from Anza
4:48:42 a.m. - a 3.0-magnitude earthquake hit 15 miles from Borrego Springs
4:48:52 a.m. - another 3.0-magnitude earthquake hit 16 miles from Borrego Springs
4:48:56 a.m. - the final 3.0-magnitude earthquake hit 14 miles from Anza
Friday's earthquake could be felt as far away as Nairobi, Kenya, by people on high floors of downtown buildings. Nairobi is 220 miles (350 kilometers) northeast of the epicenter.
The U.S. Geological Survey says the epicenter was 90 miles (145 kilometers) southwest of Arusha, Tanzania.
Africa does not have any known major earthquake zones. The area southwest of Mount Kilimanjaro is one of the few regions on the continent with regular seismic activity.
Scientists have released the menacing noise of the Japan earthquake which plunged the nation into unprecedented chaos when it shook the nation on March 11.
The cataclysmic mega-quake sent a merciless tsunami bulldozing its way through streets and homes wiping out towns and communities in a matter of minutes.
It began Sunday and continued into Thursday, with scores of small temblors reported.
On Wednesday, the region around Hawthorne, Nev., recorded a 4.4 and 4.1 quake as well as many smaller temblors. There have also been smaller quakes on the California side of the border, along the Eastern Sierras in Inyo and Mono counties.
The bulletin added that the carbon dioxide emissions of the Volcano is still in high levels which suggest anomalous gas release from the magma at depth. The Alert Level II hoisted last Saturday has not been lifted due to the increased activity of Taal Volcano.
The Institute had advised the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 -1977 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.
In today's episode of TV Patrol, it was reported that there were cracks noted on the walls and floors of the houses and on the roads in Talisay, Batangas which is 10 km away from Taal Volcano. The Phivolcs is still to investigate what caused the cracks.

Survivors in Miyako, Japan, observe a moment of silence in the rubble exactly a month after a massive earthquake and tsunami.
The 7.1-magnitude aftershock briefly forced Tokyo's main international airport to close both of its runways. The epicenter was just inland and about 100 miles north of Tokyo. The operator of the crippled Fukushima Daiichi nuclear complex said the latest quake had no impact on the plant.
A warning was issued for a three-foot tsunami, the same as for after an aftershock that shook the northeast coast last week. That quake generated no tsunami.
People at a large electronics store in the northeastern city of Sendai screamed and ran outside, though the shaking made it hard to move around. Mothers grabbed their children, and windows shook. After a minute or two, people returned to the store.
