Chile Earthquake Earth’s Axis

Chile Earthquake Earth s Axis : , March 1 AFP) – The earthquake that killed more than 700 people in Chile on February 27 that might turn the Earth’s axis and shorten the day, said the National Aeronautics and Space Administration (NASA world.

Earthquakes can involve the transfer of hundreds of kilometers of rock by several meters, and the overall change in the distribution on this planet. This affects the Earth’s rotation, said Richard Gross, a geophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses a computer model to calculate the effects.

“The length of the day should be got shorter by 1.26 microseconds (millionths of second),” Gross said Tuesday in an e-mail response to questions. “He added that the axis around the globe balanced overall must be moved from 2.7 milliarcseconds (about 8 cm or 3 inches).”

Changes that can be modeled, although they are difficult to detect because of their small physical size, “said Gross. Some changes may be more pronounced, and the islands has been transformed, according to Andreas Rietbrock, a professor of earth sciences at the University of Liverpool, who has studied the disaster area, though not since the recent earthquake.

Santa Maria island off the coast near Concepcion, Chile’s second largest city, which may be raised 2 meters (6 feet) of the latest quake, Rietbrock said today in a telephone interview. The rock show there is evidence to suggest the past to transform the island of earthquakes upward in the past.
‘Ice skater effect’

“This is what we call the impact of the ice skater,” David Kerridge President of Earth hazards and systems in the British Geological Survey in Edinburgh, said in a telephone interview. “As the ice skater puts when going on around in a circle, and she pulls in her arms, she gets faster and faster. It’s the same idea with the earth revolves If you change the distribution of destruction, and the rate of rotation changes.”

Rietbrock said he was not able to get in touch with seismologists in Concepción to discuss the earthquake which registered 8.8 on the Richter scale.

“What is certain that the earthquake has to do is to make Earth ring like a bell,” said Rietbrock.

Magnitude 9.1 Sumatra in 2004, which was born from the tsunami in the Indian Ocean today shortening by 6.8 microseconds, and shifted about 2.3 milliarcseconds, Gross said.

Changes that occur in the day, and then carry on “forever and said,” Benjamin Fong Chao, Dean, Faculty of Earth Sciences at National Central University in Taiwan, in an e-mail.
“This small contribution buried in significant changes as a result of other causes, such as atmospheric mass moves on the ground,” said Zhao.
