Earthquakes!

[Kiwi Graham]

So now there has been a big one in the Kermadec Islands.

Are we (earth) getting more of these or are they just being 'reported' more?

[Maha]

Sizable ones always get reported...if its news making (damage and/or tsunami etc)
Rotorua have 100+ annually but they are very minor and you hardly feel them.
I remember around 1979 there we counted 12 in a single day while living there.

[Edbear]

Some better reporting, yes, but records do show that over the last century or so, they have been getting more frequent and bigger. The Earth is going through a phase at the moment of plate shifting so expect more, possibly more frequent, larger earthquakes.

[dogsnbikes]

I think the equipment is just more senstive now than it was 30 years ago, so are being reported more, growing up south of Rotorua they were an everyday occuance you just lived with earth-quakes........

And the smell of bum....:blink:

enjoy the hail and fire storms, poison critters etc. Oh btw they had a shake over there recently to.

REM song released nov 1987

That's great, it starts with an earthquake, birds and
snakes, an aeroplane and Lenny Bruce is not afraid.
Eye of a hurricane, listen to yourself churn - world
serves its own needs, dummy serve your own needs. Feed
it off an aux speak, grunt, no, strength, the Ladder
start to clatter with fear fight down height. Wire
in a fire, representing seven games, and a government
for hire at a combat site. Left of west and coming in
a hurry with the furys breathing down your neck. Team
by team reporters baffled, trumped, tethered cropped.
Look at that low playing. Fine, then. Uh oh,
overflow, population, common food, but it'll do to Save
yourself, serve yourself. World serves its own needs,
listen to your heart bleed dummy with the rapture and
the revered and the right, right. You vitriolic,
patriotic, slam, fight, bright light, feeling pretty
psyched.

It's the end of the world as we know it.
It's the end of the world as we know it.
It's the end of the world as we know it and I feel fine.

Six o'clock - TV hour. Don't get caught in foreign
towers. Slash and burn, return, listen to yourself
churn. Lock it in, uniforming, book burning, blood
letting. Every motive escalate. Automotive incinerate.
Light a candle, light a motive. Step down, step down.
Watch your heel crush, crushed, uh-oh, this means no
fear cavalier. Renegade steer clear! A tournament,
tournament, a tournament of lies. Offer me solutions,
offer me alternatives and I decline.

It's the end of the world as we know it.
It's the end of the world as we know it.
It's the end of the world as we know it and I feel fine.

The other night I dreamt of knives, continental
drift divide. Mountains sit in a line, Leonard
Bernstein. Leonid Brezhnev, Lenny Bruce and Lester
Bangs. Birthday party, cheesecake, jelly bean, boom! You
symbiotic, patriotic, slam bug net, right? Right.

It's the end of the world as we know it.
It's the end of the world as we know it.
It's the end of the world as we know it and I feel
fine...fine...

I was living in Newcastle when that shook to bits too.

[wysper]

I would go with being reported more. And also earthquakes would have more news resonance in NZ just now.

[NighthawkNZ]

We now have better detection equipment and communications and have more detectors in place to detect with more being placed around the planet. I read somewhere, that we have around 15000 seismographs stations things scattered and in the next few years 1500 more will be in place...

So basically it means we are now detecting every single earthquake and now relising how many there actually are that we never knew about.

The other thing to think on, years a go you wouldn't hear about the earthquake till the next night (unless you were there) on the news (sometimes 2 days) now we hear about it with 1/2 Hr it will be on the net.

With the ChCH quake we here in NZ are now on edge about every report on an Earthquake... I was getting sick of reading about every aftershock on YahooNews... after a big quake there are after shocks one thing we know that happens... no need to report all of them. Napier had something like 8500 after shocks... ChCh is up around that number as well...

NZ has thousands of Earthquakes every year... many are to small to be detected. you can see the pattern along the main fault... But shake something hard enough it will cause and make another faultline...

I'm going down into a burning ring of fire.....


You been into the chillis again, huh?

[fliplid]

The Earth is going through a phase at the moment of plate shifting...
I think it's been going on for just a tad while longer than a moment :facepalm:

[slofox]

And the Kermadecs have gazillions of quakes...

Didn't know BD had been to Geordie land though :blink:

[Oakie]

And the Kermadecs have gazillions of quakes...
About one magnitude 7+ every three to five years.

[Edbear]

More seismographs have meant in increase in the detection of smaller quakes but if we look at larger quakes the frequency has been increasing. It's not reporting "improvements" either, as that has nothing to do with the data collected, only with the data disseminated.


Trends since 1986

For example, between 1986 and 1996 (incl), a period of 11 years, there were "just" 15 earthquakes listed by USGS of magnitude 7.0 or greater. This is not markedly different (albeit a slight decrease) from previous (similar periods) of 20th century, where an average of about 18 might be expected.

But between 1997 and 2007 (incl), a period of only 11 years, there were 99 earthquakes with magnitude 7.0 or greater : This is more than a six-fold increase on the previous similar period - and is a stark increase on any earlier decades in 20th century too.

The trends in nature here, particularly from 1997 support the wider realisation of prophesy about the "End Times", namely that an increase in earthquake activity is a pre-requisite for the "second coming of Jesus Christ" foretold in the bible. It does not indicate how close we are to this event, but suggests it is not too far away.

Future Trends

Past performance cannot necessarily be taken as a clear indication of future trends (unfortunately many scientists tend to assume too often that it is, by simply projecting forward on an existing trend, without considering other factors) so we must be careful how past events are interpreted. However, it is clear we are currently living in a time when earthquake frequency has increased, it will be interesting to see if the immediate future maintains this trend.

Other Notes

When there are multiple earthquakes (over 7.0) occuring within 5 days of each other in the same geographic area, only one has been counted. This may result in slightly different (lower) numbers for earthquakes than might otherwise be listed, although consistancy in this approach makes historical comparisons more reliable, as large after-shocks were not always recorded (in addition to the "main" quake) in previous decades.


incl = inclusive dates.

I was going to make some smart arse comment about leaving you lot to enjoy hell why I enjoyed the USA...

except I'm going up the western coast... so I'm still fucked :facepalm:
