NASA Details Earthquake Effects on the Earth |
NASA scientists using
data from the Indonesian earthquake calculated it affected
Earth's rotation, decreased the length of day, slightly
changed the planet's shape, and shifted the North Pole
by centimeters. The earthquake that created the huge
tsunami also changed the Earth's rotation.
Dr. Benjamin Fong Chao, of
NASA's Goddard
Space Flight Center, Greenbelt, Md. and Dr. Richard
Gross of NASA's Jet
Propulsion Laboratory, Pasadena, Calif. said
all earthquakes have some affect on Earth's rotation.
It's just they are usually barely noticeable.
"Any worldly event that involves the movement of
mass affects the Earth's rotation, from seasonal weather
down to driving a car", Chao
said.
Chao and Gross
have been routinely calculating earthquakes' effects
in changing the Earth's rotation in both length-of-day
as well as changes in Earth's gravitational field. They
also study changes in polar motion that is shifting
the North Pole. The "mean North pole" was
shifted by about 2.5 centimeters (1 inch) in the direction
of 145º East Longitude. This shift east is continuing
a long-term seismic trend identified in previous studies.
They also found the earthquake decreased the length
of day by 2.68 microseconds. Physically this is like
a spinning skater drawing arms closer to the body resulting
in a faster spin. The quake also affected the Earth's
shape. They found Earth's oblateness (flattening on
the top and bulging at the equator) decreased by a small
amount. It decreased about one part in 10 billion, continuing
the trend of earthquakes making Earth less oblate.
To make a comparison about the mass that was shifted
as a result of the earthquake, and how it affected the
Earth, Chao compares it to
the great Three-Gorge reservoir of China. If filled
the gorge would hold 40 cubic kilometers (10 trillion
gallons) of water. That shift of mass would increase
the length of day by only 0.06 microseconds and make
the Earth only very slightly more round in the middle
and flat on the top. It would shift the pole position
by about two centimeters (0.8 inch).

Ice age, Polar
reversal, super volcanic activities, massive earthquakes,
Tsunamis, hurricanes – we are in the middle of
a deadly 11,500 year cycle
India Daily Technology Team (Sep. 28, 2005) |
According to some geologists and scientists, we are
in the middle of a deadly 11,500 year cycle when the
ice age comes back. The start of the cycle is marked
with Polar reversal, super volcanic activities, massive
earthquakes, Tsunamis and nasty hurricanes. 11, 500
years back, the last ice age happened and what we have
started experiencing – all happened.
In the last one year the Earth experienced the largest
three earthquakes in the last two hundred years. The
under water volcanoes and earthquakes have gone up 88%
over the last three years. The continental earthquakes
have gone up by 62% during the same time frame. The
rate of increase of these earthquakes and volcanoes
when drawn against time is staggering.
We are experiencing hurricanes and storms like never
seen before in recorded history. The intensity of these
storms in the Pacific and Atlantic oceans are increasing
exponentially.
A simulation model monitoring the recent seismic disturbances
– earthquakes and volcanoes show extreme disturbance
in the outer and inner core of the Earth. The interaction
of the inner core and the rest of the earth cause the
electromagnetic properties of the earth. The ongoing
polar reversal is accelerating and will eventually have
reverse polarity in North and South pole.
According to the simulation model, the Earth’s
inner core and outer core is going through some serious
disturbances. That in turn is influencing the viscous
semi fluid mantle. When that happens, the convection
within mantle increases substantially. That is also
influenced by solar polar reversal. In our modern age
we have not experienced a simultaneous solar and terrestrial
polar reversal.
Between now and 2012, these
disturbances will keep increasing making Earth’s
crust and tectonic plates very disturbed causing severe
volcanoes and earthquakes.
