Chile Earthquake Make Shorter Day
The devastating earthquake measuring 8.8 on the Richter scale that shook Chile will change the entire Earth's rotation and shorten the length of day on our planet, according to a NASA scientist told Space.com, Tuesday.
by scientists Richard Gross of the Jet Population Laboratory, NASA, at Pasadena, California,
Chile Earthquake listed as the seventh strongest earthquake in history is likely to shorten the long days on Planet Earth up to 1.26 milliseconds.
"Perhaps more interesting is how strong the Chile earthquake that shifts the axis of the Earth," NASA officials said, in a recent statement Monday U.S. time (Tuesday GMT).
Computer models used by Gross and his colleagues to determine the impact of the Chilean earthquake also found that the quake appears to have shifted the axis of Planet Earth until approximately 3 inches (8 cm or 27 milimiliardetik).
The axis of Earth is not the same north-south pole on the planet, which rotates once each day with a speed of about 1,000 mph / miles per hour (1604 kph, kilometers per hour).
The axis is the axis of the Earth where the planet's mass balance. Axis is branched from the north-south axis of the Earth until about 33 feet (10 meters).
Powerful earthquake has changed the days on Earth and its axis in the past. The 2004 Sumatra earthquake measuring 9.1 on the Richter scale, triggering tsunami waves, has been shortened days to 6.8 microseconds and shift the axis of Earth to about 2.76 inches (7 cm, or 2.32 miliardetik).
One day is equal to about 24 hours. In a matter of years, long a normal day turned gradually to a millisecond. It was increased in winter, when the Earth rotates more slowly, and decreases in heat Masim, Gross said.
Chile earthquake is smaller than the Sumatra earthquake vibrations, but the Chilean Earthquake impact on Planet Earth is greater because of its location in the middle latitudes of the Earth, not at the equator, such as Sumatra Earthquake.
Chile earthquake fault which resulted in 2010 also cut on Earth on a steeper angle than the fault in Sumatra quake, according to information from NASA scientists.
"This is what makes Chile fracture more effective in moving the Earth's mass vertically, and therefore more effective in shifting the axis of Planet Earth." NASA scientists said.
Gross communicating the findings are based on preliminary data available in Chile Earthquake. Because information about the characteristics of the earthquake the more open, Chile Earthquake prediksanya about the impact may change.
Chile quake killed more than 700 people and caused devastation across the country in South America.
Some of the giant telescope in the Atacama Desert, Chile, escaped the impact of the earthquake damage, according to the European Southern Observatory.
A NASA satellite instruments measuring salinity mounted on a satellite Argentina also survived the earthquake shocks, according to JPL officials.
Instruments called Aquarius is located in the town of Bariloche, Argentina, who had previously been placed on satellites Satellite de Aplicaciones Cientificas (SAC-D). Satellite integration facility located approximately 365 miles (588 km) from Chile Earthquake epicenter.
Aquarius instrument is designed to be able to provide monthly global maps of salt concentration of the oceans, in order to track the current circulation and its role in climate change.
