A bit late for that.  In the last year alone - earthquakes, floods, major volcanic eruption, unusual extreme weather conditions world-wide ... reckon it could be pay-back time for our planet.
Aileen, I will never believe that it's ever too late for prayer!

Japan PM has declared a "nuclear emergency" after one of their reactor's cooling facility has failed. Think

I'm wondering about these faults in the plates - I don't really understand seismic activity - bet Buhweet could explain it ... but, I'd think that when one plate crashes into another it has a large knock on effect.  I wonder if different faults can affect each other, or if one fault line causes earthquakes related to it and it alone etc ........ (convoluted thinking, no ...  Very Happy)
The plates push against each other constantly. Depending on wherther or not it is in a subduction zone or just a plate moving in opposite directions, like the San Andreas in California.
In this case Japan is on an Asian plate which is moving above the Pacific plate. It is being affected by the Philipines plate as well. The Pacific plate is in subduction there, diving under both of those. One quake does not necessarily mean the stress is released sufficently to prevent another. In this case they say up to 30 aftershocks have occured, some even larger than the one in New Zealand. It is pretty much a normal event there, except that this quake, I understand was close to the surface. Remembering that these are giant slabs of rock, one affects another and a push here is a pull somewhere else.

I guess when I asked the question I was wondering if this current earthquake could possibly shake up the San Andreas ...

How long after the earthquake did the tsunami hit?  Did people know to get away or to higher ground?

It's hard to comprehend the magnitude of this devastation.  The volume of natural disasters that appear to be occurring in quick succession are really worrying.  I googled the 2012 thing.  Flip me, if I thought I'd only 18 or so months left, I'd be out there giving it large!  Seriously, does anyone think there's a modicum of truth in it?

It is an interesting coincidence (must be, right? nervous) that this is all happening leading up to 2012.

Hmmm, could be right.

In papers published by the Royal Society, researchers warned that melting ice, sea level rises and even increasingly heavy storms and rainfall - predicted consequences of rising temperatures - could affect the Earth's crust.

Even small changes in the environment could trigger activity such as earthquakes and tsunamis.

I wonder how come the Mayan calendar ends on 21st December 2012?  Did they run out of paper?  As far as I could glean from what I skimmed over today, there's going to be some crazy planetary alignment in 2012 that will cause a huge magnetic shift.

I don't think it will because the San Andreas is on the other side of the mid-Pacific ridge (which form the Hawaiian Islands) basically moving in opposite directions. But it could cause a big one in China.

Presumably they thought the world will end on that date.

I'll be the first to post on 22nd December 2012, and I'll take great pleasure in doing so.

Well, now.  What I can remember is, that they said the world 'as we know it' would end.  I guess that's open to a multitude of interpretations.

I'll see your post, and raise you two...

I heard one guy mention just a few minutes. There was an earth quake warning but by the time they knew it the wave was there. It was just off the coast about 80 to 100Km moving at 200 or 300Km/hour doesn't take long to reach you.
