Space Forum / Astronomy / December 2004SE Asian Earthquake & Earth's Rotation
There was a blurb on the TV news today asserting that at some point the level 9 earthquake in southeast Asia even affected the Earth's rotation! Does anybody know what was meant by that?

When the earth gets to moving around like it did in Indonesia I tend to believe that the after affects will cause weather pattern changes around the globe. If you're walking down a flat path and then suddenly the path rises 20 meters, do you think that's going to be a pretty big change to the surrounding environment? According to the USGS the shift in the Indian plate caused the Burma plate to rise significantly. That rise in relation to the global water level forced all the water in the area around it to have to go someplace else which caused the tsunami. I'm just wondering why so many people died. When you live in an area where this type of event is not totally uncommon, you'd think the people in those areas would know better. 20,000+ dead tourists would have been expected, not 20,000+ natives. Yes, it's a cold-blooded, hardcore way to view it but as is obvious, lack of common-sense sometimes carries some extreme consequences. > > There was a blurb on the TV news today asserting that at some point the > > level 9 earthquake in southeast Asia even affected the Earth's [quoted text clipped - 3 lines] > > > > Double-A http://story.news.yahoo.com/news?tmpl=story&cid=1539&e=2&u=/afp/asiaquakeusmapshift Thanks for the story. > I'm a pretty firm believer in chaos theory as it applies to weather. > When the earth gets to moving around like it did in Indonesia I tend to [quoted text clipped - 7 lines] > level forced all the water in the area around it to have to go someplace > else which caused the tsunami. I was wondering whether the rising of islands and such would shed any light on whether the Earth might be expanding or shrinking. If expanding, the rotation should slow. If shrinking, the rotation should speed up. However, if one plate is subsuming underneath another plate, then there must be some lowering of altitudes elsewhere, perhaps over a vast area, to compensate for the rising of lands at the site of the quake. > I'm just wondering why so many people died.

According to some of the reports from the area, this type of event isn't so common there. Maybe that's just their excuse for not being prepared, I don't know. But I'll bet this event will draw the nations of the Indian Ocean into setting up a Tsunami warning system similar to the one already in place in the Pacific rim. > Yes, it's a cold-blooded, hardcore way to view it but as is obvious, > lack of common-sense sometimes carries some extreme consequences. As a science oriented person, I am much more interested in hearing these science snippets about how the Earth is being affected, rather than endless compilations of the body count. Double-A This was truly a worldwide earthquake. Vibrations were detected as far away as Central Park NYC. Six-foot Tsunami waves were observed in South America some 23 hours after the quake. Today's reports are that the Earth's day may have been shortened by milliseconds. Does this indicate global shrinkage? One would think that if the Earth is continuing to cool, that some small shrinkage would be occurring. I guess I'll put off my thoughts of buying a beach house for now! The odd thing is that on the coastline near where I live, there are plenty of hills where houses would be safe. Yet everyone builds on the low ground that is not only subject to Tsunamis and storm driven waves, but also to flooding by local rivers. Look to the hills, and you see only trees. Double-A Now the news reports now say that the earthquake may have shortened the Earth's rotational day by up to 3 microseconds. If this is true, then that means the Earth is now rotating faster! This would result if the Earth's mass were to move closer it the center. Is this conclusive evidence that the Earth is shrinking? Double-A > Now the news reports now say that the earthquake may have shortened the > Earth's rotational day by up to 3 microseconds. It didn't say that the day got shorted by 3 microseconds. It said that THAT day got shortened by 3 microseconds, and the axis was shifted over a little bit because of the redistribution of mass and shock waves and all that. Buried away deep in the USENET archives within another message, a cryptic warning: >From me: >From news://misc.misc; July 26, 2004 Subject: "How will this thread end?" >This thread will end late on December 31, 2004 [...] >For hours on end, a home video will be piped in the [quoted text clipped - 4 lines] >will stop abruptly just after someone makes the >comment "it's coming!" or "it's almost here!"

If this is true, then that means the Earth is now rotating faster! This would result if the Earth's mass has pulled closer to its center. Is this conclusive evidence that the Earth is shrinking?

Assuming a rotational speed up (yet to be confirmed) is based on the conservation of angular momentum (idealized here are there are other contributing factors in the changes of the earth's rotation rate)... > Is this conclusive evidence that the Earth is shrinking? No--the earth is not appreciably shrinking or expanding. In general the Earth's rotation rate slowing from tidal friction (2 parts due to the Moon and 1 part due to the Sun). OUR RESTLESS TIDES http://co-ops.nos.noaa.gov/restles1.html we will stick you there to warn of all future events > > There was a blurb on the TV news today asserting that at some point the > > level 9 earthquake in southeast Asia even affected the Earth's [quoted text clipped - 25 lines] > Yes, it's a cold-blooded, hardcore way to view it but as is obvious, > lack of common-sense sometimes carries some extreme consequences. > we will stick you there to warn of all future events > [quoted text clipped - 6 lines] >> Yes, it's a cold-blooded, hardcore way to view it but as is obvious, >> lack of common-sense sometimes carries some extreme consequences. Foot the bill and I'll start packing. I'm all for preventing needless loss of life. Best not to move to Florida Louisiana,Alabama,or Texas. Florida has many reasons for being the worst with loss of life. I'll let you all list the reasons We might all have to move to Iowa,or Indiana Bert. |
