Shakeing In Santiagio

[JackLuis]

"Huge quake hits Chile; tsunami threatens Pacific"

"TALCA, Chile — One of the strongest earthquakes ever recorded struck Chile on Saturday, toppling homes, collapsing bridges and plunging trucks into the fractured earth. A tsunami set off by the magnitude-8.8 quake threatened every nation around the Pacific Ocean — roughly a quarter of the globe"

Fortunately Chile has much better construction that Haiti, but an 8.8!

Thanks Stella, I forgot the link.

Here it is.

And here

There is no engineer on the planet who can design a building 'proof' against an 8 and this one was almost a 9. That estimate of 122 dead is going to skyrocket. However, as was pointed out, Chile isn't Haiti.

The Tsunami warning for us in So-Cal is about 2 Feet higher waves (give or take) so I'm not going to pack up the cat and run for it just yet--

But OMG! It must have been like an atom bomb going off for Santiagio. I well remember the Northridge quake and this one was twenty times stronger That's just terrible.

And there's bound to be aftershocks.

I think it's more like 200 times? Lemme see. 7.0=32x10 to the sixth and 8.8=15.8x10 to the nineth. These numbers are too big for this bear of modest brain.

Okay, calculator on. Chile '10 is 493 times the Northridge. OMG!!!

 

[3113]

Okay, calculator on. Chile '10 is 493 times the Northridge. OMG!!!

Um, no. Actually the force is something like 32x when you move up from say, 4.0 to 5.0. So it's actually about 32x the strength of the Haiti and 64x the strength of Northridge.

Oh, and my husband and I stopped by the beach to check out the Tsunami, but I think we were too early. Nothin'.

 

[Freefall_mc]

Hang in there you all. With an 8.7?, the after affects sound scary.

I think we are using different way's of calculating. I'm using the released energy in TNT equivalents. What are you using?

 

[voluptuary_manque]

Okay, I've got it figured out. You're calculating the amplitudes, the size of the shock wave at the surface. I'm calculating the released energy in megatons of TNT. We're both right.

Ah! Okay. So if it's that many megatons of TNT, how was the earthquake in relationship, say, to an atom bomb?

 

[3113]

Hang in there you all. With an 8.7?, the after affects sound scary.

The epicenter was just off shore, near the town of Concepcion, 212 miles from Santiago. And yeah, scary is the word. Here's some pictures:

The largest thermonuclear explosion of all time was the Russian 50 megaton explosion. Compared to the Chilean earthquake, it was a snapped twig. However, it was horrifying to behold, all the same.

Atom or Hydrogen ?
The first Atom Bomb (Trinity) measured about 15000 tons of TNT.
The first Hydrogen device (Ivy Mike) was about 15 million tons of TNR.
Tsar Bomba was 57 million tons.
(Sakarov declined to make such a big bomb. He thought 50 Mt was big enough).

Now what was the TNT equivalent in Cile ?

Was that one a 'layer cake' construction ?

 

[voluptuary_manque]

Now what was the TNT equivalent in Cile ?

15.8 gigatons

It's pretty bad but at least it wasn't right undaer a population center like in Hati.

It also wasn't under a jerry-built slum, which is what most all of Haiti is.

 

[DesertPirate]

True, very True.

Fortunately Chile has much better construction that Haiti, but an 8.8!

Chile's in one of the worst subduction zones on the planet from what I understand.

That's my understanding as well. Most places the continents are sliding along at about two inches a year. The subduction under Chile is three and a half. I read where Humboldt made some very accurate measurements of the height of many of the mountains in the Andes. Today, some two hundred years after his explorations, the same mountains are some hundreds of feet higher. At the rate they are growing, the time will come when the Andes surpass the Himalayas as the world's greatest mountain range.

Update to story (Real Life)

Chile quake moved entire city 3 meters to west: study"

"CHICAGO (AFP) – The massive earthquake which struck the west coast of Chile last month moved the entire city of Concepcion more than three meters (10 feet) to the west, scientists said Monday.

Preliminary measurements drawn from global positioning stations showed that Concepcion, Chile's second largest city, is now 3.04 meters further west than it was prior to the 8.8-magnitude quake which struck February 27."

There is a plot bunny in it I know it.

WOW! All I can say is this...
