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

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).

Here are some maps of volcanic regions in eastern Australia
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!!!

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
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 there was a 7.1 quake. This was bigger than the 6.9 that flattened the freeways in San Francisco 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(1) (actually more like this) 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.....
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 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
(2)I have no pic of the '79 lego ships I built, but I had these (1 & 2) 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...
Here are some maps of volcanic regions in eastern Australia
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.

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).

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.....

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.

missing out on all the fun
