Recent World Earthquake Activity
As requested- the usual inelegant fast grab of links, but it covers the best and worst of it.
Imagine the power of 12 H bombs all going off at once.
Bless you, backhoe. You do FreeRepublic proud!
Thanks for this information - as I said last night, I may be sent as part of Australian government efforts to help assist in this, and FR is proving rather useful at helping me find information about how bad this actually is, so I can try and work out if I am likely to be sent or not.
This is looking bad enough now that I suspect I won't be going for a while. My job in such situations is to help restore educational infrastructure - reopening schools etc, finding supplies they need. This is pretty important - but if the disaster is bad enough (and this is looking like it is) it's a lower priority than getting other services working. I might wind up going in a few weeks, or months.
has anyone heard about Diego Garcia at all? I can't find out about anything....

Does anyone know how long a time elapses between the earthquake and the tsumanis hitting lang? I was a little surprised better advance warnings could not have been given, even if it's just a police officer in a truck with a bullhorn.
Does anyone know what the tide level was for the psunamis, and they velocities of which hit shore?
Follow the link at #7 and about halfway through are photos, maps & comments on DG. I had been wondering, myself.
Do you know if those are current pictures or old ones?

Actually, an 8.0 earthquake releases the equivalent energy of a 6 megaton hydrogen bomb. This was a 9.0 so it would release the energy equal to 60, 1 megaton hydrogen bombs.

Somewhere, among all those links, are some diagrams of the sea, land masses, wave action, and a little more- but dogged if I can remember which ones they were in-- you'll have to hunt. Look for a blue-green cross-section drawing of an island in the water.
It's a function of distance. I believe Sri Lanka and India had 1 1/2 hours from the quake to the Tsunami impact. Phuket Thailand would have had the wave hit sooner.
The USGS tried to contact areas but since there was no formal warning network set up by India and Sri Lanka there was no organized way to get a warning out.
It looked like an old stock photo to me- but I did not read the fine print!
Tsunamis can travel across open ocean at up to 500 mph. You could be on a cruise ship out in the middle of the sea and have one go under you and never notice it, because it would only be a foot or two high. It's only when they hit shallow water inshore that they slow down and pile up to great height.
Considering that this one caused devastation 1500 miles away from the earthquake's epicenter, there would've been at least a three-hour time lag before it hit some places. But, I guess that not all earthquakes, even powerful ones, create tsunamis this devastating...any seismologists have an idea?

Good work as usual backhoe. Ping Dolly
Thanks, prairie!
12? It's much more than that. A Magnitude 9 earthquake is 1,800 megatons.
The largest nuclear weapon ever detonated was 50 megatons (and that was a one-off stunt by the Russians that wasn't a real weapon.) This quake was the power of 36 of those.
The thermonuclear warheads we have on our missles (minuteman and Trident) are 300 kilotons.
Thus, this quake was as powerful as about 54,000 warheads from American ICBMs. Or many times more powerful than every single nuclear weapon on the world going off at once.
