Hey Matrix is there any relation to EQ in the anitpodes that correlates to Typhoons in the Equateral regions ?

Sorry I don't know Soma.   

But I can say that I have found out that thermodynamics play a part in both these.

I hope to get around to adding a thread in my forum, discussing the behaviour of "Plate tectonics"
and "thermodynamics".


Just as weather is driven by thermodynamics which can be expressed by isobars or contours
of pressure gradients, so too we find a similar phenomena within the Earth's Crust and Mantle
also having thermal convections under the surface of the Earth.

But the changes within the Earth, may be over many years, rather than days as is the case
with our atmospheric weather.
But I think you will find a similar phenomena within the earth, as well as our atmosphere.

Perhaps our weather patterns are affected by these "thermal eddies" within the Earth ?

For us to understand both phenomena I believe we need to study the behaviour of thermodynamics
within the Earth itself. I don't know IF this is already being done or not but Scientists do study
such behaviour on the surface of our planet with regard to weather patterns.

We know thunder storms and tornadoes also involve the collision of Warm and Cold air,
especially as is seen in the case of tornado alley in the US.

So perhaps there may be a connection, but I suspect, only as far as the behaviour of thermodynamics
involving a common origin i.e. the thermal environment within our planet.

But I am always willing to be educated...

Well that was a most facisinating post Mx as I don't know either! but thought it was worth throwing the question out there as it's kinda interesting and you have now made me think!

How is it possible for a planet not to have polar regions?

"Dynamics" and its Influence on Atmospheric behaviour as well as Internal.


Two odd rotating Planets in our Solar System, Venus and Uranus which rotates east to west
instead of west to east !

And the rotational Axis of Uranus points almost directly to the Sun !

If we look at the Dynamics one would expect Uranus to precess in its Orbit ?

Precession is a change in the orientation of the rotational axis of a rotating body.
It can be defined as a change in direction of the rotation axis in which the second Euler angle
(nutation) is constant.

In physics, there are two types of precession: torque-free and torque-induced.

In astronomy, "precession" refers to any of several slow changes in an astronomical body's rotational
or orbital parameters, and especially to the Earth's precession of the equinoxes.

So we have much more to learn about Dynamics on a large scale and other things which influence
dynamic behaviour I guess..

Uranus: The Sideways Planet

10 Need-to-Know Things About Uranus:

1.      If the sun were as tall as a typical front door, Earth would be the size of a nickel
         and Uranus would be about as big as a baseball.

2.      Uranus orbits our sun, a star. Uranus is the seventh planet from the sun at a distance
         of about 2.9 billion km (1.8 billion miles) or 19.19 AU.

3.      One day on Uranus takes about 17 hours (the time it takes for Uranus to rotate or spin once).
         Uranus makes a complete orbit around the sun (a year in Uranian time) in about 84 Earth years.

4.      Uranus is a gas giant and therefore does not have a solid surface. The bulk (80 percent or more)
         of the mass of Uranus is made up of a hot dense fluid of "icy" materials (water  (H2O), methane
         (CH4). and ammonia (NH3)), above a small rocky core.

5.      Uranus has an atmosphere which is mostly made up of hydrogen (H2) and helium (He),
         with a small amount of methane (CH4).

6.      Uranus has 27 moons. Uranus' moons are named after characters from the works
         of William Shakespeare and Alexander Pope.

7.      Uranus has faint rings. The inner rings are narrow and dark and the outer rings are brightly colored.

8.      Voyager 2 is the only spacecraft to have visited Uranus.

9.      Uranus cannot support life as we know it.

10.    Like Venus, Uranus has a retrograde rotation (east to west).
        Unlike any of the other planets, Uranus rotates on its side, which means it spins horizontally.


Like Venus, Uranus rotates east to west. Uranus' rotation axis is tilted almost parallel to its orbital plane,
so Uranus appears to be rotating on its side.

This situation may be the result of a collision with a planet-sized body early in the planet's history,
which apparently radically changed Uranus' rotation.

(Personally I Don't Think so NASA...   . May I suggest it has more to do with Dynamics.)

Because of Uranus' unusual orientation, the planet experiences extreme variations in sunlight
during each 20-year-long season.

The first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer
William Herschel, although he originally thought it was a comet or star.

The seventh planet from the Sun is so distant that it takes 84 years to complete one orbit.

Voyager 2, the only spacecraft to visit Uranus, imaged a bland-looking sphere in 1986.
When Voyager flew by, the south pole of Uranus pointed almost directly at the sun
because Uranus was near its southern summer solstice, with the southern hemisphere
bathed in continuous sunlight and the northern hemisphere radiating heat into the blackness of space.

Uranus reached equinox in December 2007, when it was fully illuminated as the sun passed over
the planet's equator. By 2028, the north pole will point directly at the sun, a reversal of the situation
when Voyager flew by.

Equinox also brings ring-plane crossing, when Uranus' rings appear to move more and more edge-on
as seen from Earth.

The Hubble Space Telescope and the Keck Observatory in Hawaii captured detailed images of Uranus
as the planet approached equinox. While Voyager 2 saw only a few discrete clouds, more recent observations
reveal that Uranus exhibits dynamic clouds as it approaches equinox, including rapidly evolving bright features
and a new Great Dark Spot like those seen on  Neptune.

Uranus is one of the two ice giants of the outer solar system (the other is Neptune).
The atmosphere is mostly hydrogen and helium, with a small amount of methane and traces of water
and ammonia.

Uranus gets its blue-green color from methane gas in the atmosphere.

Sunlight passes through the atmosphere and is reflected back out by Uranus' cloud tops.
Methane gas absorbs the red portion of the light, resulting in a blue-green color.
The bulk (80 percent or more) of the mass of Uranus is contained in an extended liquid core
consisting mostly of icy materials (water, methane, and ammonia).

For nearly a quarter of the Uranian year (equal to 84 Earth years), the sun shines directly over each pole,
plunging the other half of the planet into a long, dark winter.

While magnetic fields are typically in alignment with a planet's rotation, Uranus' magnetic field is tipped over:
the magnetic axis is tilted nearly 60 degrees from the planet's axis of rotation, and is also offset from the center
of the planet by one-third of the planet's radius.

The magnetic fields of both Uranus and Neptune are very irregular.

Uranus has two sets of rings. The inner system of nine rings, discovered in 1977, consists mostly of narrow,
dark rings. Voyager 2 found two additional inner rings.

An outer system of two more-distant rings was discovered in Hubble Space Telescope images in 2003.

In 2006, Hubble and Keck observations showed that the outer rings are brightly colored.

Uranus has 27 known moons, named for characters from the works of William Shakespeare or Alexander Pope.
Miranda is the strangest-looking Uranian moon: its complex surface may indicate partial melting of the interior,
with icy material drifting to the surface.



So to fully understand Earthquakes I believe that the Dynamics involving the rotation of the Planet
has a direct affect on "Tectonics", "Earthquakes" and "Atmospheric" behaviour.

How is a 4.2 strong and a 4.8 moderate?

The "Strong" and "Moderate" descriptions I think they may be based on "Ground Acceleration", rather than "Magnitude" ?

In other words we can have a high magnitude Earthquake which can either have a high or low ground acceleration.
The higher ground acceleration reflects the sharpness while lower acceleration, being more of a rolling type Earthquake I guess ?

The higher the ground acceleration, the more violent it feels, and the more damage done to buildings.

I understand that different Earthquakes have different wave profiles.

But I am NO expert in this area.
