Earth Quake

[martymas]

we have bin getting these small earthquakes

\since the big onje

the are called hummers

when they come in a series of small shakes

tho not in the city i live in

this is a small report

and it looks as tho it has gone right

through the north and south isalnd

the shake in the north island

was in and area that

had one of the biggest earthquakes we have ever experienced

back in ti 1920"s

many people died

perhaps not as big as sanfrancisco

but it must have bin frightining for the people

the city i live in is sitting in ancient crator

but it is dormant

I hope you can avoid the "big one" marty! I also live in an earth quake zone on the west coast of BC, Canada. My area is due for a large scale quake at any time.

Do they use the term "aftershocks" there? That's what they call the baby quakes that occur after a larger one (here, at least). "Hummers" has an ENTIRELY different meaning.

I'd take it as a good sign that things are settling down -- for a while we hope.

ime not sure why they are called hummers

i think it is a term from

the little after shocks

which used to have a ripple affect

and go on for several days

or weeks

we here down under have to live with it

it must be terryfing for people who live in earthquake zones

like japan

california. ect

i saw a graph

on tv

and the fault line we have in nz

runs right accross the pacific

to the shores of the usa

i used to worry about them but not any more

they are interesting

natural part of nature

when i first became aware of earthquakes

i nearly shit myself

They need to figure out how to secure the plates together somehow. That way they can't shift and cause Marty to have to clean himself up all the time. lol

Just wait till the eco freaks get carbon sequestration programs underway.

If I were a gambling man I would lay odds that they will stir up all kinds of earthquakes by pumping pressurized liquid carbon dioxide into deep wells.

[MrBill]

The oil companies have been pumping nitrogen into the old wells forcing the remaining oil out of the cracks and crevasses for years.

[martymas]

ok at last i have some one who agrees with me

man hasent helped

earthquake zone here has bin

with us for millions of years

geez i feel old

one scientist thinks

when the moon is full the gravity from the moons pull causes these hummers

Ah but nitrogen is on thing and liquid carbon dioxide another.

Liquid CO2 is a heavy duty solvent; and can act as a lubricant.

The nitrogen under similar temp and pressure will remain a gas and even as a liquid is not a solvent or lubricant.

Speaking of lubricants, in proper circumstances (like when the hydrated magnesium silicate - TALC lubricates a fault line) lubricants will keep the quakes small and smooth , while where the fault line is dry it will grab and lurch. But therein lies the rub. The small slips can put added stress on areas that cannot slip and eventually lead to the big one.

Of course it is all necessary, part of the carbon cycle that keeps our planet liveable. The Nuclear fission reactor at the core of the planet drives the tectonic plates which recycle the water and carbon and they in turn lubricate this conveyor to keep it running smoothly.
