I have never felt an earthquake.

But I can imagine that there is a very cool feel. You can live in California so very well with it. In Austria, there are very few earthquakes .. "Unfortunately." a magnitude 5 quake is not "very" destructive, but cool.

How do you think?

I've felt a few - a couple in Greece and a couple here in New Zealand. Before I moved here to NZ from the UK we'd never had to deal with the threat of an earthquake. I haven't felt anything "big" though - and even though I know the consequences - I'd like to.. in a weird sort of way...!

Is the depth for this quake unusually deep, or are quakes frequently this deep?

reply to post by this_is_who_we_are


Yep, that's pretty deep... the area does see quite deep events but this is on the higher side. There was a 581km deep one about a week or so ago near the same spot.

If you check back through the list linked below - you'll see many of the deepest events are Fiji.

I wonder if a number of high magnitude quakes with extreme depth is an indicator of something major on the way.

BIG revision down to 5.4 and 490km depth...

I suspect it's more due to the geology of the area, it's always been active, too.

This was 96km NE of us, and I notice there is one Felt report from Paraparaumu, but we didn't feel it.
Being that far away and on the wrong side of the mountains I can't see how they could tell it was an earthquake and not just the wind, its been blowing 100km/hr winds for 2 days now.

I think you are right Austria

Heres a list of recorded 5+ quakes from iisee 3000BC to 2008
Not many at all
I bet there were more thousands /millions of years ago when the Alps were younger.

map showing location of above earthquakes

thats just ones with the tag Austria, off course there may be more in surrounding countries that would be felt in Austria, especially 6+ quakes

Regarding what they feel like ........
Well it depends where you are at.
3's I've felt have been mostly one jolt.
I've felt lots of quakes in the high 4's around where I live, they are what I call "rattlers", sort of everything shakes for a few seconds and then goes quiet, some are like freight trains passing through a tunnel a few feet below you.
5's in our area tend to be jolts, usually a couple of them, sudden bangs and maybe a slightly tapering off shake.

I have only felt 6's when in bed at night, the scenario is usually that they are quite long in duration, shaking back and forth and quite noisy with a bit of wobbling at the end. I've felt 2 of them like that, and the question asked was do you get out of bed or is it going to stop?. The latest safety message out there is to roll off the side of the bed and lay on the floor, creating the Safety Triangle above you in case the house collapses.

7's are a whole different ball game, I've only felt 1, it was at the Kermadec Islands 1500km away, a 7.6 . No jolts, no rattling, just THE WHOLE FREAKIN WORLD WOBBLED AND SWAYED BACK AND FORTH for about a minute.
It was quite disorientating, I can see how people close lose their balance and fall over.
I wouldn't want to be within 50km of a 7, thanks

I slept through a 4.99 earlier this year it was only 1.5 km from my house. Go figure.

The worst quake I have been in was actually not here in NZ but in Pizzo, Italy in 1980.
That was scary . But thats another story.



[edit on 8-7-2010 by muzzy]

I thank you for your "opinion" I'm always happy about people who can tell of something like that.

Yes, the earthquake in Italy was terrifying.
1980 11 23 - Southern Italy - M 6.5 Fatalities __ 3.000

Yaaaaay, I'm so happy. But still sad.

There was an earthquake in Austria today. It had the strength 3.2

But I have slept. -.-

You are mad Austria. I don't wish to experience an earthquake thank you very much.

Reading about them is quite close enough!!! It might shake the froth of me Guinness and we can't have that.

5.2 quake right under Krakatoa just now

Just a bit more on this quake, 3 aftershocks to the east, thats quite a lot for a "light" quake, maybe there is something bigger in the pipeline?, perhaps more to the west? There has been a big hole (very few quakes) in the South Taranaki Bight for a few weeks now.

There were a couple of minor quakes close to me just after that event, at Raumati South. 100km south west from the 4.3 and on totally different faultlines. Can't say I felt them though, just after 9pm local time, I was watching TV.
