Check out the wiki-page for list of earthquakes in Japan here - http://en.wikipedia.org/wiki/List_of_earthquakes_in_Japan.
It shows the foreshocks on March 9th 2011 and the Sendai earthquake on March 11th with an 8.9 magnitude. Of course, followed by plenty of aftershocks. This earthquake is the fifth largest ever since man knew how to measure earthquake. Probably, if Noah had this Ritcher scale with him, he might have recorded more earthquakes with higher magnitudes. So what exactly did this earthquake do to our Mother earth other than creating a huge Tsunami and killing thousands of people?? Here is a little bit of academic review.
According to experts, this earthquake has moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis. This shift in the axis is 10 centimeters according to National Institute of Geophysics and Valcanology. This shift is so small for a ball of 6370 km radius which is spinning at 30 km per second. But it has some impact which only experts claim to understand. There is one major impact. Mother earth has started spinning faster, now!!! Yeah, which makes our everyday shortened by 1.6 microseconds. (A microsecond is the equivalent of 1/1,000,000 of a second).
Imagine a girl, coming out of a shopping mall with loads of shopped items in her hands, asked to spin about her own centre in an ice skating pond. She will spin at a speed slower than she could spin before entering the mall. It is not because she is tired shopping, it is because of the bags she is carrying in her hands. Those bags increase her momentum during spinning and it decreases the speed of spinning or rotation, technically. Holding a bag of 3 kgs in each hand keeping it stretched to the maximum and then slowly bringing it close to the body will increase the speed of spinning. This is because the moment of inertia falls as she brings the bags close to her body and so her angular velocity increases. This is why ice skating dresses are designed taking care of this angular momentum. The more they are close to the body, they can spin faster and faster, when they do ice skates. In fact, if she was spinning nude in the ice pond, she will be spinning the fastest for sure but making the entire world literally slower for the men audience.
This exactly happened here in Sendai earthquake. The quake has pulled in some of the tectonic plates close to its centre and pushing others outside(lets not bother the names now). So now its like, earth is spinning with her shopping bags close to her body. And she started spinning faster - thereby reducing our day by 1.6 microseconds. Previously, 2004 Indian Ocean quake reduced our day by 6.8 microseconds and
2010 Chilean earthquake reduced our day by 1.3 microseconds. There is no direct impact to a common man because of these negligible changes, which is like a sparrow hitting a flying Boeing Airbus 380 both at their maximum speeds.
So therefore there is not much to hype on this topic as many news channels claim. Even the experts are not sure what long term impacts they may cause. But media makes the common man feel that the world is towards its end. One of the news channels claimed that this earthquake was a result of global warming and related shit. I expect them to telecast how dinosaurs gone mad using cars and refrigerators millions of years ago to cause global warming and earthquakes. Or even how manufacturing industries in Atlantis caused global warming making the continent disappear into the ocean.
Finally, on a lighter note, if the earth keeps increasing its speed of rotation and reaches 30 times its present speed, one good thing is that we can get the paycheck everyday!!!

gud analysis ...example adds spice to technicality n helps comprehension!
ReplyDeleteTimely blog... Conclusion is old, but very apt here... Keep it up....
ReplyDeleteWow...Syam you deserves the hats off , in such a tight schedule, you find time for your blog. Good work dude.
ReplyDeletegood job syam :)
ReplyDeletejust imagining what it would be like to receive a paycheck everyday :P
