Shift in Earth's Axis

The 2010 Chile 8.8 earthquake may have changed the entire Earth's rotation and shortened the length of days on our planet, a NASA scientist said on Monday.The quake, should have shortened the length of an Earth day by 1.26 milliseconds, according to research scientist Richard Gross at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
"Perhaps more impressive is how much the quake shifted Earth's axis," NASA officials said in a Monday update.The computer model used by Richard Gross and his colleagues to determine the effects of the Chile earthquake effect also found that it should have moved Earth's figure axis by about 8 cm or 27 milliarcseconds.

The Earth's figure axis (axis around the Earth where the Earth's mass is balanced, offset from the Earth North-South axis by 10 metres) is not the same as its north-south axis, which it spins around once every day at a speed of about 1,604 km/h.

Strong earthquakes have altered Earth's days and its axis in the past. The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami, should have shortened Earth's days by 6.8 microseconds and shifted its axis by about 7 cm or 2.32 milliarcseconds.One Earth day is about 24 hours long. Over the course of a year, the length of a day normally changes gradually by one millisecond. It increases in the winter, when the Earth rotates more slowly, and decreases in the summer, Gross has said in the past.

The Chile earthquake was much smaller than the Sumatran temblor, but its effects on the Earth are larger because of its location. Its epicenter was located in the Earth's mid-latitudes rather than near the equator like the Sumatran event.The fault responsible for the 2010 Chile quake also slices through Earth at a steeper angle than the Sumatran quake's fault, NASA scientists said."This makes the Chile fault more effective in moving Earth's mass vertically and hence more effective in shifting Earth's figure axis," NASA officials said.

Gross said his findings are based on early data available on the Chile earthquake. As more information about its characteristics are revealed, his prediction of its effects will likely change. The salt-measuring NASA satellite instrument destined to be installed on an Argentinean satellite was also undamaged in the earthquake, JPL officials said.

2010 Chile Earthquuake

The 2010 Chile Earthquake occurred off the coast of the Maule region of Chile, on 27 February 2010 at 06:34UTC. The earthquake was a magnitude of 8.8 and lasted about 3 minutes. It was the seventh strongest earthquake recorded in the century. The cities experiencing the strongest shaking—VIII (Destructive) on the Mercalli intensity scale—were Talcahuano, Arauco, Lota, Chiguayante, Cañete, and San Antonio. The earthquake was felt in the capital Santiago at Mercalli intensity scale VII (Very Strong). Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru. Tsunami warnings were also issued in 53 countries, and a tsunami was recorded, with amplitude of up to 2.6 m high, in the sea at Valparaíso, Chile. The epicenter of the earthquake was offshore from the Maule Region, approximately 8 km west of Curanipe and 115 km north-northeast of Concepción. The earthquake also caused seiches to occur in Lake Pontchartrain to the north of New Orleans, United States, located nearly 7,600 km from the epicenter of the quake.[20]

Purpose of Blog

This blog post was meant to be the first. Sorry for the late blog post......


This blog will be used for Language Arts. It is for certain LA assignments and for ACE. In this blog, I will also be blogging about Climate Change and Disasters around the world. I chose this topic because I think it is really important for us people to know that we will continue to destroy our home, and we will be the ones suffering, not anyone else. I chose Natural Disasters because they are consequences to global warming. Natural disasters can also reveal one's personality. We will be amazed by the miracles and the victims' ordeals.

*There is no need to comment on this post.

Reflection on Multiple Intellligences Test

I feel that the test is somehow a little accurate and a little off. It is accurate because I do not know much about nature, and I am weak in languages. However, the reason why I say it is a little off is because I know myself better than I know languages. The test actually allowed me to know myself a little better. I just realised that when I moved around to study, I study better.I also realised that i am intrapersonal and it actually links up with the reason on why I thought of the subject ‘Climate Change and Disasters’. After I thought deeply into the connection, I found out that I thought of the topic because I cared for people. I knew that I was Number Smart because I was always good at numbers. In my primary school, Mathematics was my best subject and I alwaysseem to be able to do it at ease. I wonder how do they come out with the questions that can actually tell you your so-called personality?

LA Home Learning Assignment

I chose to do the activity on this particular learning style: Kinaesthetic(Body Smart)

i. When Charlie is taking a test to determine if he’s suitable for the operation

This picture shows that one is nervous. Charlie is nervous because he is afraid that he would fail the test.








Source: http://www.cccoe.net/social/bodylang.htm

This picture above shows that one is worried. Charlie is worried that he would not be suitable for the operation and hence not able to be smart like the others.


ii. When Charlie realizes that his friends had been making fun of him all this while







Source: http://profalbrecht.wordpress.com/2008/12/30/ace-your-accounting-classes-12-hints-to-maximize-your-potential/

This picture shows that one is angry. Charlie Gordon is angry with his friends that they had humiliated him. He is also angry with himself that that he had been with those types of friends without knowing it.

iii. When Charlie realizes that Algernon has died.







Source: http://chuckmullis.wordpress.com/2009/02/05/depressed-about-dating/

This image shows that one is depressed and wants to be left alone. Charlie Gordon wanted to be left alone despite being offered help from Miss Kinnian. He was depressed because Algernon was the only friend he had and now he was dead and could never be by his side.
