Is it crazy to think that there may be a pattern for all these strong earthquakes in the past few years since the Haiti one, and that they may be linked?

It's the Pacific Ring of Fire, which includes Haiti, Japan, Chile, New Zealand, Solomon Islands and Indonesia (list goes on) which have had deadly quakes in the last few years - http://en.wikipedia.org/wiki/Ring_of_Fire *edit, not Haiti which has its own crazy deep-earth stuff going on in the area

The ring of fire doesn't seem to include Haiti: http://arstechnica.com/civis/viewtopic.php?f=26&t=36428

The Caribbean instead has it's own smaller "ring": http://www.csmonitor.com/World/Americas/2010/0121/Haiti-eart...

No: http://wcatwc.arh.noaa.gov/events/PAAQ/2013/05/24/mnafyn/2/W...

indeed, as this document indicates : "DUE TO THE DEPTH OF THE EARTHQUAKE NO TSUNAMI IS EXPECTED."

The Depth of the subterranean earthquake is generally a major factor in Tsunami (The main factor being the displacement of the water mass above).

The last two M9~ magnitude earthquakes causing deadly tsunamis (Indian Ocean 2004, Japan 2011) were only at a Depth of 30km (19mi). This one is very deep, at 619km (385mi) below the surface.

I personally always get Haiti and Papua New Guinea confused in my head. I know they are very different, but for some reason I have to think for a few seconds when someone says Haiti.

These messages are always in caps to send faster over slower systems. http://www.alternatewars.com/BBOW/Computing/Capital_Letters.... I spent a decade as a communicator in the navy and radio teletype is still the primary method of communication at sea.

That makes sense. However, I argue that the NOAA could serve their warnings on the web in all lowercase for the sake of readability. Then again, that could be a quick hack for someone.

* { text-transform: lowercase; }

If it bothers you so much. :)

There is an idea where strong earthquakes are linked to the end of large-scale nuclear tests.

Presumably nuclear tests helped tensions to resolve in small earthquakes and now they build up and release a devastating one.

Why is this still all-caps - in 2013? It's not like there are any teletype lines left that cannot process lower case. Is this some kind of tradition or does NOAA still use EBCDIC mainframes?

fwiw the tsunami warning systems (one each coast) in the usa are currently in the process of selecting and implementing a major upgrade (i am working on one of the bids in a very minor role[1]) so you can expect changes in the next few years (but i have no idea about this particular issue).

[1] which, incidentally, involved me sending thousands of SMS alerts to a co-worker yesterday evening as i ran through a replay of the chile earthquake, effectively DOSing[2] his phone. most entertainment i've had in months. beep. new magnitude estimate. beep. beep. beeeeep... :o)

[2] it's ok, it's only a demo, promise.

Being in Moscow, which is 6000+ km away from the epicentre of the earthquake, we still felt the tremors... Fascinating.

I find this very hard to believe.

It's possible because of the depth.
