Small Tremor!!!!

[renormalised]

Just had the house shake a bit about 2-3 minutes ago. A short sharp jolt that lasted about 2-4 seconds. Felt like a small earthquake, probably about 2-2.5 on the Richter. Hard to say, really, but we couldn't find any immediate cause for the shaking.

[Strawb]

Yep got it too Carl - woke me up from my siesta

[renormalised]

Wonder where the epicentre was??. Would have to be closeby, being so small. Wish I still had my geological maps for the area....there's about a dozen or more small faults around here, plus you have the major Hodgkinson-Palmerville Fault which partly runs just off the coast along here.

GA initial report (http://www.ga.gov.au/earthquakes/getQuakeDetails.do?quakeId=3025605&orid=404917&sta=MTSU)


Near Bowen, QLD.
Magnitude (http://www.ga.gov.au/earthquakes/staticPageController.do?page=glossa ry#magnitude): 5.4 (Mb)
Depth (http://www.ga.gov.au/earthquakes/staticPageController.do?page=glossa ry#depth): 24 km

They ask for reports from people who felt it

[supernova1965]

I felt it in Mackay

[ballaratdragons]

5.2 according to USGS http://earthquake.usgs.gov/earthquakes/recenteqsww/Quakes/usc0002stu.php

[renormalised]

Yeah, just went to their site....5.2 according to the USGS.

[AdrianF]

It is on the news now as a 5.1

Adrian

[renormalised]

Actually, GA recorded it as 5.4, and that was from the Mt Surprise seismograph....a lot closer to the epicentre than the USGS. And, in any case, what would the news lot know....if it was left upto them, it would get smaller every time they came on air to report it.

[Ric]

Blimey, there's never a dull moment in Queensland.

[mithrandir]

GA revised it down to 5.2 in their 16:32 update.

Who's to say it won't change some more later, in either direction.

[renormalised]

They're only following the USGS lead.

[ballaratdragons]

Actually Carl, knowing what the media is like, they like sensationalism (Drama sells News) they would keep trying to raise the Magnitude.
The less the Magnitude, the less newsworthy it is :rolleyes:

[renormalised]

Yeah, that's true....it might become a 10 on the Richter soon enough:):P

[ballaratdragons]

:rofl: yep.


I can remember one reporter on FoxNews doing an interview when Japan was struck.

The Seismologist confirmed it as a 9.0 and she kept getting excited and saying "but it could be a 9.5" and he would say "no" and she would keep repeating "but it could've been", until he finally said "yes, it possibly could have been, but it wasn't" :lol:

Then after she had finished the interview she very seriously faced the camera and said "There you have it, and now some video of the resulting horror of that terrible earthquake measured at a possible 9.5 magnitude"

Archie Carumba! :lol:

[renormalised]

That's why I hardly watch TV news anymore. It's not worth the effort and you don't get the facts...all you get is the fantasy.

[Mick]

We didn't feel it we were in the car at the time. But I had to laugh our 20 year old was at home at the time and he hunted the dogs as he thought they were scratching fleas under the kitchen table. :lol:

[OICURMT]

If you felt this earthquake, you can describe it and it will be logged into the USGS system.

[Suzy]

Gosh, you guys must have really wondered "what tha" heck is going on! :eyepop:
Not everyday you get to experience an earthquake.

Oh dear, I really think Queensland has had enough now. :sadeyes: Well said there Ric - never a dull moment in Queensland it seems. :rolleyes: Let's hope all these disasters of late have now finally come to a stop.

What's weird is seeing the postings here of some of you'll wondering what's going on before it became news. How often does that happen..:question: :lol:

Did it moves cups and plates? Cushions fall over? What did you experience?
Strawb got woken up from a snooze so I'm guessing his bed shook :question: From the quake :rolleyes:

[Nortilus]

well it made my house shake for a few seconds and strong enough to make my monitor on my desk wobble a bit and Im in mackay

[Waxing_Gibbous]

We had a one last year and again earlier this year centred on Korrumburra in S. Victoria.
Thought it was cattle stampeding.

[astroron]

I have never experianced an Earth Quake,it must be a strange feeling as the ground and the buildings start to move all around you:eyepop:

I was raised in Peru (mother's from Lima), so I've experienced quite a few from small to rock-N-rolling...

My family lived in Indonesia for four years and I remember when we had a minor tremor rip through Jakarta. My family's first experience...

My two younger sons were having a blast as we lived on the Penthouse floor of our apartment building (23rd and 24th floor). The movement was about 1/4-1/2 meter sway at that level, nice and gentle (building was designed for a 1.5 meter sway).

My youngest (4yrs at the time) was running around in his socks sliding on the hardwood floor yelling in glee as he was having a blast not being able to walk straight... my wife was almost crying as she wasn't sure what was going to happen to us. I told her to relax and that everything would calm down in a few seconds (not much you can do on that high up except wait it out or head down the stairs).

That particular quake was about 150km from Jakarta, so it was pretty gentle compared to some I've experienced.

[Liz]

Hmmm ... didnt feel a thing here, and a group of us were down on the beach. I am about 30 min north of Tville though.

[Analog6]

Considering Newcastle was 5.6, then 5.1 could cause damage depending upon epicentre/depth.

[supernova1965]

It was 10 klm deep but we are a tough breed up here:P:rofl:

[renormalised]

There was another shock yesterday around 4.7 and today of 3.3 (at 11:35am)...all in the same general area.

[bartman]

mmmmmm whats next......
Are there any dormant volcanoes in QLD?:confused2:
NOT that I wish one upon any of you in Queensland or the Beautiful State you live in:thumbsup:
Bartman

[renormalised]

Yes, there are....some around and near Charters Towers and Mingela, and also north of there, up around the Undarra Lava Tubes (Lava Plains). There's quite a large number of shield volcanoes and cinder cones in the region. I've climbed up a few of them and been down some lava tubes (not Undarra).

[supernova1965]

Here are some maps of volcanic regions in eastern Australia

[bartman]

Thanks Carl and Warren,
I'm not to clued on with geophysics, and I dont want to stray off topic, but could an earthquake ( depending on depth, strength and location) affect a dormant volcano?
And no....I'm not in the media and don't want to scaremonger!!!:scared2:
Cheers

[mithrandir]

I have a few examples.

16 Oct 1999, 09:46 UTC (02:46 local). My cousin Christine's birthday. She lives in San Francisco. We were asleep in one of the hotels in Anaheim.

Out near Joshua Tree NP (http://earthquake.usgs.gov/earthquakes/eqinthenews/1999/ushector) there was a 7.1 quake. This was bigger than the 6.9 that flattened the freeways in San Francisco (http://earthquake.usgs.gov/regional/nca/1989/) 17 Oct 1989.

From the 12th floor we watched:


the pool next door emptying itself across the carpark,
powerlines arcing as they swung against each other,
transformers exploding within Disneyland from the power surges.


No-one was reported killed. The worst injuries were on an Amtrak train which was derailed.

Before that, I was at work in Pitt St Sydney when the Newcastle quake hit. A New Zealand co-worker exclaimed quite loudly "It's a <impolite words removed> earthquake." The only one I remember before that was either the 1961 Robertson or the 1973 Picton one. Those three were all about 5.5

My own experience with an earthquake was when I was a kid at just ten years old....
Playing with my lego - trying to build a spaceship to the likes of this (http://i937.photobucket.com/albums/ad216/bartman691/lego%20stuff/lego-crash.jpg)(1) (actually more like this (http://kazza.id.au/10030/) :lol:) but ending up with something like Destiny(2) from SGU in the end....I didnt have enough pieces.....( and I only use Destiny as a reference as, of course at the time SGU ....well you know the rest.... I ramble..)
From memory , playing in the main living area, the room started to sway.....for some reason I was laying on my back and looked up at the chandelier we had. It was swaying big time and all of a sudden I realised something was wrong and I got scared....I got up staggering, yelling out to mum....
By the time I reached her in the kitchen it was over and all was good.
From memory we had no damage and I quickly went back to adding things to my spaceship.....:D
I believe it was the Cadoux Earthquake in 1979, June 2.
Rocking On!!!

Just a bit ( waaayyy) off topic - sorry hehehehe:

(1)Imperial Star Destroyer destroyed (http://i937.photobucket.com/albums/ad216/bartman691/lego%20stuff/lego-crash.jpg) after I tapped it with the vacuum cleaner.....cant find a completed model pic...I know I have it somewhere....BTW Millenium Falcon, AT-AT (motorized) and V19-torrent in the pic as well.
Yes un-sharp pic...I was inebriated :rofl:

(2)I have no pic of the '79 lego ships I built, but I had these (1 (http://i937.photobucket.com/albums/ad216/bartman691/lego%20stuff/928-1_003.jpg) & 2 (http://i937.photobucket.com/albums/ad216/bartman691/lego%20stuff/920-2.jpg)) as some base models and Destiny seemed - from memory - the closest representation to what I built back then...it had wheels too.... 30 odd years ago...

[renormalised]

Yes...I'm very familiar with the Nulla Basalts, Chudleigh Park and the McBride Volcanics (Lava Plains). I've also been to some of the others (Sturgeon, Hillsborough, Clermont etc). There are still some hotspots in and around these places where the residual and radiogenic heat warms up groundwater and you get hot springs.

[renormalised]

I remember the Picton quake quite well. Threw Dad out of bed and woke everyone up:)

[renormalised]

Yes, it could, but there are many factors determining the reactivation of a dormant volcano, one of which is how long has it been dormant for. Unless the source of the volcanoes is still in or near where they erupted, they most likely won't go off again. That being, they've moved too far from the magma that supplied them (moved away from the mantle plume that supplied the intrusive rocks that produced the volcanoes).

[bartman]

This still intrigues me Carl, and I'm not sure if I should proceed in this post. but any hooo......
So, if for instance, the recent quake in QLD might move the magma/mantle plume slightly and could possibly have shifted some of the intrusive rocks to allow a crack/ subsidence and then allow the dormant 'volcano' to re-activate.......
by allowing magma to seep through those cracks and weaken the fissures,
Once again I should probably post this in a new tread.....

[FlashDrive]

oooooh ....!! Gee Wiz Liz .... you missed out .... this is just not on .. eh ...!!! :mad2: missing out on all the fun :D

[renormalised]

No, the plume is at quite a depth....40-50kms or more below the surface. It's usually smaller blobs coming off the top of the plume that act as the direct magma sources for the volcanoes. It's the plate on which Australia sits that moves over the plumes (mantle plumes are usually stationary) and so you get a chain of volcanoes that forms as the plate moves over the plume. However, if the plate cracks to depth, there might be a slight chance for a new eruptive episode to occur over the top of the plume. Although, it also depends on if the plume itself is still there. They do eventually disappear over time.

[Liz]

:lol::lol: Colin, I know!! Everyone else I have spoken to felt it. I think we must have had too much champagne on board. :rolleyes:

Quite a few aftershocks coming through, not that I have felt those either. Paluma felt them though - about 30 min north and west up the mountains.
