Queensland – 2nd earthquake in two days – Strongest in almost a century

“I live in Caloundra on Queensland’s Sunshine Coast,” says reader Rosco.

“On July 30 a 5.3 magnitude earthquake was reported about 100 km offshore. I didn’t notice this one.

“Yesterday, August 1, I certainly noticed the effects of a quake.

“The frame of our house was stressed and moved and settled slightly – not visibly but audibly. I looked towards a large window where the noise appeared to come from but nothing was visible.

“I turned back and noticed the blades of the ceiling fan visibly vibrating in a high frequency. They stopped after about 30 or so seconds.

“Queensland has been rattled by another earthquake — the strongest in almost a century — and two strong aftershocks, two days after a similar-sized quake hit the region.

“Senior seismologist Dan Jaksa said a magnitude-5.7 quake struck at 1:38pm on Saturday, with its epicentre 110 kilometres due east of Fraser Island at a depth of 10 kilometres.”

“This is equivalent to the earthquake that occurred in 1989 in Newcastle, which of course is the most damaging earthquake in Australia’s history,” said Jaksa.

Australia is one of the least active earthquake localities on Earth. The “ring of fire” is many hundreds of kilometres away from Australia.

However eastern Australia, particularly SE Queensland and northern NSW has remnants of ancient huge volcanoes – the Glass House mountains and Mt Warning. Both of these possibly would have been up to 100 kilometres in diameter at near sea level today when active – you can still see the extent of the footprint in the circle of hills surrounding the remaining “plugs”.

“Geoscience Australia has warned more earthquakes may follow.

“Enough already.”

  1. More news from Australia.

    Snow on the beach in Hobart, Tasmania.

    http://www.9news.com.au/national/2015/08/03/09/51/hobart-wakes-to-best-snowfall-in-almost-30-years

    Hobart, Tasmania is situated at about 43 degrees South – similar to the northern end of NZ’s South Island or say Bandon, Oregon.

    Mt Wellington is only 1271 metres high and has regular snow – even rarely in summer.

    But this snow fell at sea level – Hobart is on the large estuary of the Derwent River.

    PS – Tasmania has some spectacular scenery !

  2. I live in SE Queensland also, smack in the middle of an ancient volcanic region which includes the Glasshouse Mountains area just south of here. These volcanoes are very old, nothing but volcanic plugs now, however, I’m reminded of the fact that volcanoes often form above rising crustal melt from subduction zones, the principal cause of volcanoes like Mt. St. Helens. We are far from the Ring of Fire, however, the crust from the Pacific plate subducting under the Australian plate is probably melting somewhere beneath our feet. This is a geologically stable area, and we are not prone to tectonic earthquakes of any sort, however, earthquakes are also associated with rising magma. I’m just wondering what might be in store for this previously volcanic region of SE Queensland… I guess we’ll find out soon enough!

  3. A Tasmanian rescue helicopter has abandoned plans to winch out a couple trapped with their car in Mount Field national park after heavy snowfall in the state.
    The couple were stranded in the snow on Lake Dobson Road on Sunday night and remain trapped.
    A helicopter crew landed nearby late this afternoon and walked to the couple, but were unable to winch them out due to deteriorating weather.
    A local ground crew is now on its way to the site, and more snow is expected in the area.
    Police Inspector Gary Williams said authorities were still having difficulties extracting the couple.
    “That vehicle, there’s probably half or about three quarters of a foot of snow at that area at the moment and we are having some difficulty getting to that vehicle,” he said.

  4. Also, NZ fur seal seen in Queensland waters (27S LAT) this (my guess) due to colder waters in northern Tasman sea. These animals dont normally come far north as nearly into tropical waters!

    • But it seems as if he’s blaming the oil and coal industry for their deaths. So these researchers were obviously warmists. I think the whole thing is a load of bull,,,,

    • Piers Corbyn has suggested that the spin rate of our planet is being slightly braked by the solar wind. He thinks that as we get closer to a solar minimum, the breaking is weaker, which could result in a ‘jolting’ effect on oceans and plate tectonics. This effect could exacerbate earthquakes.

      Of course the ‘experts’ will not pay any attention to his theory. 🙁
