Sydney - A 5.7-magnitude earthquake rattled popular tourist towns stretching across more than 1 000 kilometres of Australia's north-eastern coastline on Thursday.The quake hit at a depth of seven kilometres about 54 kilometres off Bowen in Queensland State, the United States Geological Survey said.Buildings in Townsville city were evacuated, the Townsville Bulletin reported, but police said there were no reports of major damage.Australia's Bureau of Meteorology said there was no tsunami warning for the island continent."It's been widely felt right up the coast, from Sunshine Coast up to north of Townsville, so quite a lot of the Queensland coast has felt some shaking," Geoscience Australia senior seismologist Jonathan Bathgate told AFP."We haven't had any reports of damage at this stage. The fact that it is 50 kilometres offshore is the reason for that. If it was closer to the coast it might have been a different story."We would expect to get aftershock activity after an event of this size."Townsville resident John Towning said the shaking lasted for about six to seven seconds."I thought, 'there's no train around, no plane around', then I got up and had a look and I thought, 'geez, the whole bloody place is shaking'," Towning told the Australian Broadcasting Corporation."I sat down again and it was like the bloody chair was vibrating... It was more funny than scary. You don't normally get those things here."The tremor followed a 4.6-magnitude quake that struck 126 kilometres off the Queensland city of Bundaberg, 800 kilometres south of Bowen, early on Sunday.The strongest recorded quake in Australia was a 6.6-magnitude earthquake that hit the small mining town of Tennant Creek, Northern Territory, in January 1988, according to Geoscience Australia.
