Whole Island of Sumatra Moved 100 feet
That is amazing. In a single instant.

And the whole humanitarian loss is just devastating. It is so great that it is unimaginable.

Was Krakatoa this big?

2. so far, Krakatoa was worse, but who knows what the final #'s
will be from this disaster.

Found some cool facts about Krakatoa, including:

"4. At least 36,417 people were killed, most by the giant sea waves, and 165 coastal villages were destroyed."

3. And wsn't the air darkened for years after - due to all of the ash?
But it did cause amazing sunsets and sunrises.

We think we are such a big deal until something like this happens.

4. it caused "the Year Without a Summer"
all that ash prevented a summer from occuring all over the world. there's old british newspapers reporting on that year because europe didn't get a summer that year because of all the particulates in the atmosphere keeping away the normal amount of solar radiation.

it also was loud enough to be heard by a british clipper ship some 800 miles away somewhere in the indonesian area.

the island blew up, emptied its magma chamber and then what was left of the island collapsed within the empty magma chamber. the tsunamis must have been easily crested over 50' high, most likely 60' or 80' in areas.

22. I think that was the eruption of Tambora - 1815
Although global temps did drop slightly in response to Krakatoa as well.

5. I am no physicist, but Sumatra is a BIG Island, MUCH bigger than Krakatoa
was...

Think of the energy that would be in an earthquake that moves an island which is nearly 1000 miles long and 200 miles wide, and how deep? Just 100 feet. It boggles the mind

http://www.lonelyplanet.com/destinations/south_east_asia/sumatra/


I haven't read about the 100 ft displacement yet. Do you have a link?

31. LWolf (below has a link) that mentions 100 ft displacement
of the entire Island of Sumatra. Which would involve an incredible amount of energy.

A 100 ft lateral movement would be easily detected with even not very sophisticated GPS systems.

So, if this isn't a confusion in the early reporting, there ought to be upcoming stories about how airport runways and such no longer match their GPS coordinates etc.

11. Oh, yeah. God wanted all the people killed. God loves and causes all
Edited on Mon Dec-27-04 09:56 AM by Pirate Smile
the tragedies in the world. God causes genocide, war and starvation?

Ever heard of free will to go along with Mother Nature?

Did you ever think maybe God doesn't pick which team wins and which team loses? Who scores the Touchdown?

I don't think God is a micro-manager.

I don't think God is the weather forecaster for the world everyday and decides when to shift the plates in the earth to cause an earthquake.

Do you really think God decides that?

16. There is no plan. Everything that happens does not happen for a reason.
I am willing to buy into the Gaia principle - that the earth is a living organism that acts as an amoeba acts - just because it "is".

However the idea that some omnipotent God would conduct mass murder operations as part of a "plan" is rediculous. It strikes me very curious as to why this devastation could be part of some "plan": vague to its point, indiscriminate of its victims and cruel in its application.

Since you're privy to God's plan, perhaps you'd like to enlighten us!

Yeah, a plan. Okee dokee. Sure. Were that true, I'd get the hell outta Dodge, cuz if He's pissed at people, that tsunami was a warm up pitch for what he has in store for those of us that defile the planet the most. Note: If you live near the White House...run!

Edited on Mon Dec-27-04 10:31 AM by hatrack
. . . which lies deep below the surface of the earth. Below the mantle lies a liquid core, and below it a solid inner core, the whole thing thermodynamically powered by heat generated from gravitation and from the decay of radioactive elements. :eyes:

34. Nah...made me think of George Carlin.
He's right, you know. (Emphasis mine)

"The planet isn’t going anywhere, folks, we are! We’re going away. Pack your shit – we won’t leave much of a trace. Thank God for that. Nothing left. Maybe just a little Styrofoam. The planet will be here, and we’ll be gone. Another failed mutation; another closed-end biological mistake.

The planet will shake us off like a bad case of fleas. And it will heal itself, because that what it does; it’s a self-correcting system. The air and water and earth will recover and be renewed."

37. Carlin still rocks!!!
It's amazing how the album that's from "JAMMIN IN NY" and "WHAT AM I DOING IN NJ" are STILL RELIVANT. Nice to see we learn from history, NOT! Nothing like a year with FOUR hurricane in a little more than a month and an earthquake so strong it knocks a large island 100 feet while at the same time altering THE ORBIT OF THE PLANET! Sleep tight!

10. Is Mother Earth in ass-kickin mode?
Supervolcanoes

snip

"The last supervolcano to erupt was Toba 74,000 years ago in Sumatra. Ten thousand times bigger than Mt St Helens, it created a global catastrophe dramatically affecting life on Earth. Scientists know that another one is due - they just don't know when... or where.

It is little known that lying underneath one of America's areas of outstanding natural beauty - Yellowstone Park - is one of the largest supervolcanoes in the world. Scientists have revealed that it has been on a regular eruption cycle of 600,000 years. The last eruption was 640,000 years ago... so the next is overdue."

Old Faithful?

12. This earthquake changed the earth's orbit.
It was that powerful. However microscopically, the earth's orbital path around the sun changed in just two hours. This information per CNN - sorry no link.

I thought I felt an increase in temperature as the Earth changed orbit.

It is now almost ten degrees here.

21. Thank you for the links.
Really fascinating (and I apologize that I didn't look for the links myself...guess I didn't really believe there would be any, to be honest...)

The LA times article answers a lot of questions I had too!
(i.e., how much time between the earthquake and the tsunami hitting some shores - about two hours; how tsunami's work, etc.)

The magnitude 9.0 earthquake that struck off Indonesia on Sunday morning moved the entire island of Sumatra about 100 feet to the southwest, pushing up a gigantic mass of water that collapsed into a tsunami and devastated shorelines around the Indian Ocean and the South China Sea.

30. Scary stuff, Toba supervolcano is on Sumatra!
Earthquake moves island of Sumatra


Los Angeles, CA, Dec. 27 (UPI) -- The magnitude 9.0 earthquake off Indonesia moved the island of Sumatra about 100 feet to the southwest, the Los Angeles Times reported Monday


http://washingtontimes.com/upi-breaking/20041227-092017-3455r.htm



Notice Toba, a volcanic center on Sumatra. Toba erupted last around 75,000 years ago.
“Toba caldera produced the largest eruption in the last 2 million years. The caldera is 18 x 60 miles (30 by 100 km) and has a total relief of 5,100 feet (1700 m). The caldera probably formed in stages. Large eruptions occurred 840,000, about 700,000, and 75,000 years ago. The eruption 75,000 years ago produced the Young Toba Tuff. The Young Toba Tuff was erupted from ring fractures that surround most or all of the present-day lake.”

40. Some info about the Toba supervolcano


Comparison of volumes produced by some of the greatest volcanic eruptions. The Young Toba Tuff has an estimated volume of 2,800 cubic kilometers (km) and was erupted about 74,000 years ago. The Huckleberry Ridge Tuff, erupted at Yellowstone 2.2 million years ago, has a volume of 2,500 cubic km. The Lava Creek Tuff, erupted at Yellowstone 600,000 years ago, has a volume of 1,000 cubic km. The May 1980 eruption of Mount St. Helens produced 1 cubic km of ash.



Toba is located near the Sumatra Fracture Zone (SFZ). Stratovolcanoes in Sumatra are part of the Sunda arc. Volcanism is the result of the subduction of the Indian Ocean plate under the Eurasian plate. The subduction zone is marked by the Java Trench. The geologic symbol for a subduction zone is a line with "teeth" (black triangles). The teeth are on the over-riding plate (the Eurasian plate in this case).
