it was one hell of a quake.

'Earth still ringing after Indian Ocean quake'

SYDNEY: Much of the Earth was still "ringing like a bell" two weeks
after the December 26 earthquake that unleashed devastating tsunamis
around the Indian Ocean, Australian scientists said on Sunday.
Australian National University scientists said hyper-sensitive gravity
measuring equipment showed minute reverberations may continue for
weeks.
Herb McQueen, from the university's Earth Sciences Research School,
said the equipment at the Mount Stromlo observatory in Canberra showed
the planet was "ringing like a bell" which had been forcefully struck.
He said the movement was imperceptible to all but the most sensitive
equipment.
"(It) corresponds to about a millimetre of vertical motion of the
earth," he said. "The early signals were much stronger."
McQueen said it was a rare seismic event, picked up by the
observatory's machines, which are normally used to map the structure
of the planet's interior.
Immediately after quake, which measured 9.0 on the Richter scale, US
geophysicists said it made the Earth wobble on its axis and
permanently altered the map of Asia by moving some small islands up to
20 metres.

Man, I bet this is just messing with LIGO big time.
LIGO = Laser Interferometer Gravitational-wave Observatory

Probably giving it a detailed test. How many chances will they get such a
documented event followed by the fade out documented by other methods. What
better way to test your equipment & hypothesis.

True, but since Mother Earth is going to take a while to settle
down from this ringing, it's going to be a while before they can
start getting results again. I understand they were just begining
to get calibrated into the desired sensitivity region.
This thing is so sensitive it can detect the movement of it's
test masses to much less than the diameter of an atom.

Its the sea its sef that rings like a bell.
Fire a bottle rocket in any pnd or lake.
Then try a M80 .
I fire 2000 pounds c4 in sonic imaging ,,20 years ago.
Now we use a PING around 5 million watts.
The air cannon was popular for a ring.
I herd a pingger on a sub in drydock.
it went BANG BANG but in the water it is pinggg pinggggg wile in the
air its a sharp BANG ,,

Ya mmI herd it.
herd it 1500 times.
Depends where it echoed.
It snapped on the sea floor where the crust is
14000 feet thick.
It echos between contenets that are 45000 feet thick.
just on that plate ,,the echo was limited to the 2 plates that slid
by another.
