Quake and Tsunami Devastate South Asia
pfb writes "From reuters, 'The world's fifth-largest quake in a century has hit southern Asia, triggering a speeding tsunami that crashed into Sri Lanka and India, drowning hundreds, and swamping tourist islands in Thailand and the Maldives.'"
...set off by the 8.9 magnitude earthquake...
Windows in JAKARTA, Indonesia, were rattling, and some even broke. And that is a 2-3 hour flight away from the epicenter!
Actually only the preceeding earthquake is unpredictable. When you know where the epicenter of the earthquake is and the topography and makeup of the ocean floor, you can see where the resulting tsunamis (if any are created) will hit hardest.
Unfortunately, you don't have much time between the quake and the tsunami hitting. I hear if Canary Island (The one ready to fall into the sea and wipe out the east coast) would cause a tsunami that could travel across the Atlantic Ocean in 45 minutes, and I read on the BBC that this most recent tsunami was going 2,000km/h, which seems to be roughly the same speed. Mind boggling though.
Also hurting any warning effort is how do you get a mass warning out to places like Sri Lanka? There's no mass media infrastructure and only the minimum of transport infrastructure. I suppose part of this tragedy is how unavoidable it was in these nations' current states. Only Japan has invested any significant amount of money in Tsunami warning systems.
Yup...
As these events are rare around this part of the world there has so far not been a need to set up a warning system.

Of course, this all happening at full moon will probably fuel the people who study whether the gravitational pull of the sun and moon impacts the occurrence of earthquakes like it does tides.
Village idiot in some extremely smart villages.
Can anyone put some kind of comparision between the energy release here and the energy release of the prospective planet impactor 2004MN4 ? It would help to put things into scale, if not perspective.
If MN4 were to hit, estimated release is 450-2000 MT of TNT, so how does a Richter 8.9 compare.

I'm on an island right next to Sumatra (relatively), and there were huge tsunami's hitting us too. The last I heard 15 people died in the floods. It's not as bad as what people in Sri Lanka and India experienced, but still...
My mom felt the quake at around 9, I didn't notice anything though. I'm very thankful Malaysia is relatively safe from quakes, but I feel so sorry for all who were affected.

I heard about it late last night on a net radio feed (my time EST 0 dark thirty am sometime, I was half asleep) right after it happened, but a tsunami wave travelling roughly the speed of a commercial jetliner doesn't give a lot of leeway even if the people in the soon to be affected areas hear about it.
And this one follows that 8. something quake that hit between tasmania and antarctica just the other day.
I think this story should be taken into consideration along with the asteroid stories, as this wave was only roughly 40-50 feet high, yet by some reports it traveled up to half a mile inland in some places. Just imagine one ten times higher (something like that) from a large asteroid oceanic strike.
But ya, you would think that their would be some sort of emergency alert tied to seismographs, that would automatically get posted to various radio and television and internet sources if it was of sufficient strength, ie, danger. I know we have this alleged emergency alert system in the US that will over ride the TV and radio stations OTA broadcasts, but no idea in other nations what they have for that. Civil defense is always lesser funded than military offense in most nations it appears. What would it really cost to develop a radio based alert system for these various nations? Cost of one jet fighter or tank? And it could be tied to cellphones for that matter through the various national carriers, say, in a true natural disaster (impending or otherwise) scenario, your phone might ring with a pre recorded short message.
I realise in the poorer areas it might be problematic, but surely someone in most areas has a phone or a radio or whatever, you don't have to get the message to every single human directly, just to enough of them in any given area for word of mouth to help out a lot. Wake up and alert one dude per poor village, he can go running outside yelling his head off for that matter, like "dang evac! Tsunami coming! Move it people!" something like that anyway. The old church bells ringing hard and fast deal.
What is interesting is that there was another quake on the 24th of 8.1 off the coast of Tasmania, the other side of the continential plate that caused this one ( AFAIK). That end of the plate gave way and that affected this one? A warning? I don't know, but it might have been related.
Massive earthquake felt in Tasmania
December 24, 2004 - 7:55AM
The world's biggest earthquake in almost four years has struck 800 km
off the coast of Tasmania, Australian seismological officials said.
Geoscience Australia said the quake, measuring 8.1 on the Richter Scale
hit the Macquarie Rise, in the Pacific Ocean, at 1.59am. [...]
It's a Bagel.
Realize that, like yourself, many did not associate the earthquake with a tsunami. CSI Miami (a US TV show) had a tsunami hit Florida in the program. So right now, when I hear "earthquake" and "water" my brain's primed to think "tsunami."
I imagine that a lot of earthquake people have the knowledge and training that they, too would think "earthquake." But they still may have been caught by surprise. The places that were close by could not be warned, and how many would have thought "hmmm - Sri Lanka's gonna get it?" It's a thousand miles away. Again, it may not have occurred to everyone.
For those it did occur to, there's the question "What do you do?" There may have been an assumption - "someone's got the job to issue the warning." If there is an appropriate "responder," often you can make things worse by trying to get involved and tying up resources as a result. So some may not have bothered because they thought that it would be handled. Others may simply not have known who to call.
I'm sitting here wondering. Let's say I'd been online looking at an Earthquake page when the 8.9 quit. Who would I have called to warn about a tsunami hitting Sri Lanka? I don't think I'd have thought my calling would do any good, first off. But let's say I put it all together and decided to start making calls. Who would I call? The Sri Lankan embassy? 911?
I have no freakin' idea.
This is why public safety organizations have emergency drills. Stuff like this happens and you do what you do every day. Who's job is it every day to warn the people of the Indian ocean if there's a tsunami? No one. So everyone did in the emergency what they do every day, which turns out to be just that - nothing.
The more I think of it, the more this looks like one of those events you learn from. At this point the question is, how much do you learn?
This sig seemed like a good idea at the time....
