Calif. thinks they cornered the market on Earth Quakes.
« on: June 03, 2009, 07:14:49 AM »
Getting kind if tired of rocking and rolling.  Watching the lights swing on their chains, and the ceiling fans swinging in circles.  Our house has cathedral ceilings and the lights and fans are hanging on long chains and rods.  The wife sitting up at night in bed gasping and grabbing my arm with a death grip.  Going out into the garage and finding things on the floor.  Even if I don't feel it the dogs do and go ballistic.  It's getting kind of old.  I keep thinking about the 9.something we had back in 2002 that shook the Alaska Pipeline off it's saddles, and damaged the walls, and broke windows in my house.  Heres an exert from todays Daily News Miner:

FAIRBANKS — Earthquakes continue to rattle through Ester and Chena Ridge nearly two weeks after the first quake struck on May 23.

More than 60 earthquakes have occurred in Alaska’s central region since 4 p.m. Saturday, the strongest being a 3.8 magnitude quake on Sunday at 9:35 p.m. just outside Ester.

A majority of the recent quakes register at less than a 1.0 magnitude, meaning it is unlikely anyone in the Fairbanks vicinity felt them according to seismologists with the Alaska Earthquake Information Center.

Quakes continued into Monday, with the strongest registering at a 1.39 magnitude at 4:13 a.m.

At 9:53 a.m. Tuesday, a 1.37 magnitude quake rolled through an area 4 miles southwest of Ester. Just three minutes before that, a 2.13 magnitude quake hit an area 6 miles west of Manley Hot Springs.

As of Tuesday afternoon, there were no reports of damage.

While Fairbanks is no stranger to a sporadic shake here and there, seismologists with the Alaska Earthquake Information Center say the recent tremors are somewhat unusual.

“It’s unusual because it hasn’t happened in a while — since 1967 to be exact, where there were three magnitude 5 and greater earthquakes in the Fairbanks area,” seismologist Natasha Ruppert said.

The earthquakes are not a result of the Denali Fault line, she said. The fault line is located about 100 miles south of Fairbanks near Denali Village.

“These earthquakes are associated with seismic activity, which we’ve known about for as long as we’ve been detecting earthquakes in Alaska,” she said.

Ruppert said that while most earthquakes are associated with faults, it’s difficult for scientists to locate any faults in the Ester area given the lay of the land.

“To know exactly where faults are, geologists need to map those structures, and that is hard to do in Fairbanks because glacial deposits, gravel, ground cover and heavy vegetation make it hard for geologists to look for rocks to identify where faults may lay,” she said.

Questions arise as to whether the recent tremors are foreshocks for a larger earthquake but Ruppert said it’s hard for scientists to forecast future earthquakes based on current activity.

“This is a known area for seismic activity, so people should prepare for any seismic activity if they live in the greater Fairbanks area,” she said.

I'm betting they stop now that goofy is out of the country courting the muslims, if they start up again when he returns the Man Upstairs is making is feelings known  ;)

Look at it this way. When things are shifting it is a lot less dramatic when it does a little bit at a time over a short period vs  nothing for a long time and then a HUGE shift.  ;)

 this is an absolute uneducated guess.. but what if we find out as the oil leaves the grnd the earth loses its hydralic fluid to keep pressure up everywhere.. not to mention creating a vacuum way dn there somewhere..
 now that guess came outa the back cornfield ,,didn t it..slim :)
 did i mention i was old school country..

I have always heard, as long as there are little one, you don't have to worry about big ones.  Well what if that is wrong.

What bothers me is can this be a precursor to the big one?  Like how you hear small pops and snaps just before a board violently breaks.

Don't blame you for being concerned, the seismologist essentially said it is fairly unpredictable. It's interesting how animals like your dogs are more pressure sensitive, similiar to when a storm is coming. Was there a similiar pattern of events prior to  the one in 2002?

well there is that possibility although I think it is less likely then the more gentle solution of shifting Plates............we hope.

I was told by someone with more smarts then I have that the oil and natural gas cavities are replaced/filled with water seeping in.  

That brings up another thought, not that I would worry about it in my remaining life time, hower:

All that oil that has been removed did reduce and will continue to do the mass/weight of the planet Earth. At what level will that change the ballistics in the earth's orbit? With less mass we should be moving closer to our solar systems center of gravity.   HEY Al, that would change our climate !!

World wide quakes:

http://earthquake.usgs.gov/

This site is a bit misleading as it shows quakes of one strength or more for the US, and another strength or more for the rest of the world.

That New Madrid fault is going to really cut loose some day, and it's out in the middle of all that flat land. That's going to make the earth's crust ring like a big sheet of metal, and there's going to be destruction for many, many miles in all directions.

BBF:  Even thou the oil and gas are removed from the eatrh's core, it stays a part of the total mass of earth.  It does not leave the planet, therefore there is no effect with the planet's orbit.

Sourdough :)
I hate to disagree with you mainly because I'm an agreeable type ;)
however the oil( some of it anyway) gets converted to gas and heat. The gas is part of our envelope and does add to the mass, the heat portion however is gone. Natural gas has no emmison other then heat and it is equally gone.   


I think.

BBF:  I'm also an agreeable type.  But if I remember my chemistry right, when natural gas is burned, it puts off heat and CO2.  It does not put off the other bad things like Carbon monoxide, and particulates, but it does emit carbon dioxide.  I will check tomorrow to be sure, but I feel confident my memory serves me correctly this time.  I'll let you know what I find out.  Rog

The molecular mass is unaffected by the production of heat.  It may be transformed into a different compound or element, but the molecules are still there.

Sourdough, my sis lives up on Chena Ridge and she was telling me about those shakers. Haven't felt any in Bristol Bay. But it would have to be big for me to feel. With lively 7 and 11 yr old boys in the house everything is shaking all the time anyway.  I felt a good shaker up there when I was in college in the early 70's.  Moore Hall made quite a cracking sound.

Oh and what I recall from my education up there at UAF, I'm with you on this Sourdough. I believe the first law of thermodynamics may apply. From Wikipedia:
"The first law of thermodynamics, an expression of the principle of conservation of energy, states that energy can be transformed (changed from one form to another), but it can neither be created nor destroyed. " While this law addresses energy I think it may also apply overall to mass as well. Otherwise the world has been getting significantly lighter from the burning of coal and oil for a long time. 

Maybe some professor can chime in....
