Did the earth move for you?

Did anyone else in Hobart feel the earthquake this morning? Apparently it was only about 600 km's off the coast.

It woke my husband and me up around 2am this morning.
We live in a beachside suburb, about 30 minutes from Hobart and I think these places felt it more than further up into the city and suburbs. Who else felt it?
It took a little while to realise what it was at first. Scary stuff!

 

[MightyFighting]

No, try harder next time.

According to seismologists it was the largest quake to hit the world this year. 8.1 on the Richter scale if it had have hit in a populated area it would have been devastating. Bloody hell I thought I was living in a paradise, just 600 km's closer and I may have been history!

I'm in Lauderdale and felt nothing.

I'm in Howrah, woke up in the middle of the night, but don't think it was because the house was shaking or anything..

 

[Syd]

Tasmania = Paradise??

...I thought I was living in a paradise...

And here I always thought you lived in Tasmania....

 

[Bee]

I am in Seven Mile Beach. We felt it.

What you felt was merely an aftershock of the massive ******** I dropped before I went to bed. Monster.

Sure it was the earthquake Bee.
You guys are a married couple now, no need to find excuses to explain these things away.

Oh, hang on, you are married now, then it must have been an earthquake!!

I don't think the faultline is going to move so I think you're safe.

Beautiful spot.

Rode a pushy around Tassie in 1990. Remember going horse riding along that beach - lovely.

So what was it? A horse or a bike?

My missus reckons I resemble a horse. I reckon she resembles a bike.

I was online during the early hours of this morning, and I remember someone else from Tasmania posting here that they'd just felt an earth tremor as they were were posting. Can't remember who it was though, or which thread it was.

Yep, quite a lot of people in this area own horses. And you often see them riding them along the beach.

8.1 is one big mother of a quake

Surprising it didn't form some kind of tidal wave, coz an 8.1 quake will cause movement along the fault line

Apparently the reason it didn't was because it was horizontal and not vertical. Or something like that.

Large quake strikes off Tasmanian coast

Seismologists say an earthquake which struck 700 kilometres south-east of Hobart overnight was the largest the world has experienced this year.

The quake struck north of Macquarie Island just before 2:00am, and was felt by residents on the state's east coast.

It was originally thought to measure 7.8 on the Richter scale, but the magnitude has now been revised to 8.1

Geoscience Australia Seismologists Cvetan Sindadinovski says the quake would have caused widespread devastation had it struck a populated area.

"If I can put it in parallel with the Newcastle event of 1989 for example, this was about 30 times larger,"

Dr Sindadinoviski says the quake did not cause a tsunami or unusal tidal activity because it was a horizontal rather than a vertical displacement.

The Macquarie archipelago is the only island group in the world composed entirely of oceanic crust and rocks from the mantle, deep below the earth's surface.

The island group, with mountains rising to 400 metres above sea level, became a UNESCO World Heritage site in 1997 due in part to its unique natural beauty and in part to its diversity in fauna.

Its colony of king penguins, numbering around 850,000, is one of the largest in the world

Okay, a horizontal quake is where the tectonic plates slide sideways against each other, the earthquake is the sudden jerking release

eg.- one plate wants to move north, the other plate wants to move south, the longer it takes between movement, the greater the pressure build up, the higher in magnitude the quake will be when the slide suddenly happens.

the verticle quake is when the plates move apart, or move into each other, the mid atlantic trench is one such example of movement

if they move away from each other, the central crust breaks apart, causing the underlying magma to ooze upwards, filling the gap, this has been a verticle displacement because the sudden breaking of the crust is a downwards movement, then a sudden upwards movement with the magma surging upwards.

if the plates move towards each other, the usual occurance if for one plate to slide upwards over the top of the other plate, causing obvious upward and downward movements. This sudden drop is displacement, which if underwater, is filled in by that water, causing a tsunami to form.

Typically the largest tsunami will be about 30 meters in height.

A mega-tsunami is caused by something completely different to earthquakes

Here is a not so well known but very possible casue of the end of civilisation as we know it...

http://www.solcomhouse.com/yellowstone.htm

I saw this on Discovery a few months back. Basically this thing in Yellowstone has blown its lid on a regular 600,000 year cycle. The last one waas 640,000 years ago and the lake has been found to be tilting due to movements in the ground.

There are others in the world (eg. Toba in Indonesia), but this is the one that's next due to go. Don't panic though folks, it's as likely to go off in 1,000 years as it is next year.

It is a worry though.

To tie this into the (intelligent) life on other planets debate, apparently the earth has been in one of the most stable periods of its existence, allowing higher forms of life to flourish. This may well be very rare. It's scary to think that it's not a matter of if an apolyptic event occurs, it's a matter of when. And it will happen. If not a super volcano, then something else.

I've heard this too. Basically it's a statistical freak of nature that we haven't had something like this happen for so long, whether it be this, a mega asteroid, or an uncontrolled plague of Port Adelaide supporters.

FACT is something will destroy civilisation on earth as we know it one of these days, whether it be done by nature or as a result of our own actions remains to be seen.

Edit - and yes Higgs, if you're worried about this I agree that beer is as good an answer as any!!!!

That would be I, BomberGal.

Felt it here in North Hobart quite gently, certainly nothing compared to that experience I had a couple of years ago. But my girlfriend who lives in Warrane had the walls shaking quite a strongly.
